The probability that fewer than two of the seven households are one-person households is:P(x ≤ 1) = P(0) + P(1) = 0.002 + 0.0322 = 0.0342.

The statistical abstract of the United States reports that 38 percent of the country's households are composed of one person. If 7 randomly selected homes are to participate in a Nielsen survey to determine television ratings, the probability that fewer than two of these homes are one-person households is 0.0813.Explanation:Given that the statistical abstract of the United States reports that 38% of the country's households are composed of one person.Now, we have to find the probability that fewer than two of these homes are one-person households when 7 randomly selected homes participate in a Nielsen survey to determine television ratings.

We are given: The proportion of one-person households = 38% = 0.38. The proportion of households with more than one person = 100% - 38% = 62% = 0.62. We are supposed to find the probability that fewer than two of the seven households are one-person households.The required probability is the sum of the probabilities of selecting 0 one-person households and 1 one-person household.

P(x ≤ 1) = P(0) + P(1)P(0) = probability of selecting 0 one-person households P(1) = probability of selecting 1 one-person householdn = 7, r = 0 P(0) = (7C0)(0.38)^0(0.62)^(7-0) = 0.002 P(1) = (7C1)(0.38)^1(0.62)^(7-1) = 0.0322

Step-by-step explanation:

The pole measures 500 centimeters.

We are required to perform unit conversion to find the answer. Conversion of unit requires the relating link between two units. While relating the two units, usually greater unit holds singular or unit value, which is 1. The smaller unit holds value greater than 1, but at equivalent level with first unit. So, as per the known fact, 1 meter is equal to 100 centimeters. Using this formula to find measurement of 5 meters in centimeters.

1 meter = 100 centimeters

5 meters = 100 × 5

Performing multiplication to find the measurement of pole in centimeters

5 meters = 500 centimeters

Therefore, the measurement of pole is 500 centimeters.

Answer: 57.6m

Step-by-step explanation:

That's a lot of words that questions usually use to try to trip us up but not this time so lets pull all relevant information

199.2m= top of off shore oil rig

-9.6 m is the base of the rig

observation deck is 1/6 of the total height

helly pad is 22.8m above the observation deck

First lets try to find the total height of the rig. We can do this by adding the absolute value of the top and base of the oil rig. So 199.2 + 9.6 = 208.8m

So the total height is 208.8m now lets find the observation deck. We know the observaition is 1/6 of the total height which is 208.8m right so lets multiply. 1/6*208.8m= 34.8m

Now we know the observation deck is 34.8m high. Finally we can find the helly pad which is 22.8 m above the observation deck.

Since the observation deck is 34.8m and the helly pad is 22.8 above observation deck (34.8m) all we have to do is add so 22.8+34.8= 57.6m

So we know the total height is 208.8m

The observation deck is 34.8m

And the helly pad is 57.6m

Answer: The answer is 7x.

Step-by-step explanation:

Answer:

The answer is x=9 and y=1

Step-by-step explanation:

First, you have to substitute x from -4x to 9y which is -4(9y).

That would equal -36y.

Then the second equation would look like this:

-36y + y = -35

Then simplify. If you add -36y and y, it would equal -35y.

-35y = -35

Divide -35 on each side.

y = 1

To find the x value, you have to plug 1 into the first equation. (It doesn't matter which equation you plug into).

So if you plug it into the first equation it would look like this:

9(1) = x

9 = x

If the bag contains a total of n blocks and m of them are blue, we would expect to have selected a blue block approximately (m/n) * 12 times out of the 12 draws, assuming the selection process is random and the probabilities remain constant.

Let's assume that the bag contains a total of n blocks, and m of them are blue blocks. The probability of selecting a blue block on each draw, P(blue), would be m/n.

Since we are replacing the block after each selection, the total number of blocks in the bag remains the same throughout the process. Therefore, the probability of selecting a blue block on each draw remains constant at m/n.

To find the expected number of times we would select a blue block, we can multiply the probability of selecting a blue block on each draw (m/n) by the total number of draws (12):

Expected number of blue blocks = (m/n) * 12

The reasoning behind this is that in each individual draw, the probability of selecting a blue block is m/n. By performing 12 independent draws, we can expect to encounter this probability m/n a total of 12 times on average.

Therefore, if the bag contains n blocks with m blue blocks, we would expect to have selected a blue block approximately (m/n) * 12 times out of the 12 draws.

The correct option is C. Randomization.What is randomization? Randomization is a process that randomly assigns subjects to either a control or an experimental group to reduce bias in scientific research.

Randomization can be done by using various methods such as random number tables, coin flip, and so on.The main objective of randomization is to avoid subjective biases, confounding variables, and statistical outliers in an experiment, to establish cause and effect relationships in a research study.

For instance, in a clinical trial to test the efficacy of a new drug on hypertension, randomization can be performed by dividing the participants into two groups randomly, one group receives the new drug (treatment group), while the other group receives a placebo (control group).The advantage of randomization is that it ensures that known and unknown confounding variables are distributed evenly between the two groups.

Thus, the chances of drawing incorrect conclusions from the research are minimized. It also increases the generalizability and reproducibility of the results obtained.

The first angle is 37.5° and the second would be 52.5°, after we plug in x.

Have a nice day. Feel free to ask questions. Spread The Love.

Answer:

Concept:

Here, we need to know the idea of the complementary angle.

Two angles are said to be complementary if they add up to 90 degrees.

Be aware that three or more angles cannot be complementary even if their sum is 90 degrees.

Solve:

Given information

Angle 1 = x

Angle 2 = x + 15

Given expression deducted from the definition of the complementary angle

Angle 1 + Angle 2 = 90

Substitute values into the expression

(x) + (x + 15) = 90

Combine like terms

(x + x) + 15 = 90

2x + 15 = 90

Subtract 15 on both sides

2x + 15 - 15 = 90 - 15

2x = 75

Divide 2 on both sides

2x / x = 75 / 2

\(\boxed{x=37.5}\)

Find the measure of angle 2

Angle 2 = x + 15 ⇔ Given expression

Angle 2 = (37.5) + 15 ⇔ Substitute values into the expression

Angle 2 = \(\boxed{52.5}\) ⇔ Simplify by addition

The expression equivalent to -3 - 3x -1x is 4 - 2x.

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

To get to this you can combine like terms:

-3 - 3x - 1x = -3 - (3x + 1x)

= -3 - (4x)

= -3 - 4x

= -4x - 3

Along the set of curves given by y = kx, the function f(x, y) will have a constant value as it tends to (0, 0). The correct answer is option d.

To determine along which set of curves the function f(x, y) is a constant value, we need to evaluate the function along each curve and observe where the values remain constant.

Curve: y = kx^2

Let's substitute this curve equation into the function f(x, y):

f(x, y) = f(x, kx^2)

Since we are interested in the values of f along the curves that end at (0, 0), we need to evaluate the function as we approach this point. Let's consider the limit as (x, y) approaches (0, 0):

Lim(f(x, kx^2)) as (x, y) -> (0, 0)

Evaluating this limit is necessary to determine whether f remains constant or approaches a specific value as (x, y) approaches (0, 0). Without further information about the function f, we cannot make a definitive conclusion for this curve.

Curve: y = kx + kx^2

Substituting this curve equation into f(x, y):

f(x, y) = f(x, kx + kx^2)

As before, let's evaluate the limit as (x, y) approaches (0, 0):

Lim(f(x, kx + kx^2)) as (x, y) -> (0, 0)

Similarly, without more information about the function f, we cannot determine if it remains constant or approaches a specific value along this curve.

Curve: y = kx^3

Substituting this curve equation into f(x, y):

f(x, y) = f(x, kx^3)

Evaluating the limit as (x, y) approaches (0, 0):

Lim(f(x, kx^3)) as (x, y) -> (0, 0)

Once again, without additional information about f, we cannot ascertain whether it remains constant or approaches a specific value along this curve.

Curve: y = kx

Substituting this curve equation into f(x, y):

f(x, y) = f(x, kx)

Evaluating the limit as (x, y) approaches (0, 0):

Lim(f(x, kx)) as (x, y) -> (0, 0)

Here, we can observe that as (x, y) approaches (0, 0), the value of f(x, kx) will depend only on x (since y = kx). Therefore, along this set of curves, f will be a constant value because it does not depend on the value of y or the specific choice of the constant k.

In conclusion, along the set of curves defined by y = kx, the function f(x, y) is a constant value as (x, y) approaches (0, 0). Hence, the correct answer is option d.

The formula for the volume of a pyramid in terms of the base area (b) is b = (3v) / h.

To rewrite the formula for the volume of a pyramid in terms of the base area, we can rearrange the equation v = bh/3.

1. Multiply both sides of the equation by 3 to eliminate the fraction: 3v = bh.
2. Divide both sides of the equation by h to isolate b: b = (3v) / h.

To rewrite the formula, we start with the original formula v = bh/3. We want to isolate the base area (b), so we first multiply both sides of the equation by 3 to eliminate the fraction, resulting in 3v = bh. Then, to isolate b, we divide both sides of the equation by h, giving us b = (3v) / h. This final equation allows us to find the base area (b) given the volume (v) and height (h) of the pyramid.

The coordinates of the specified vertex after the given sequence of transformations is given by;

Q' = (3, -3).

In Mathematics, the translation of a geometric figure to the right simply means adding a digit to the value on the x-coordinate (x-axis) of the pre-image of a function while a geometric figure that is translated up simply means adding a digit to the value on the y-coordinate (y-axis) of the pre-image or parent function.

Mathematically, a horizontal translation to the right is modeled by this mathematical expression g(x) = f(x + N) while a vertical translation to the positive y-direction (upward) is modeled by this mathematical expression g(x) = f(x) + N.

Where:

By translating the coordinate Q (1, 3) two (2) units to the right, we have the following:

Coordinate Q (1, 3) → Coordinate Q' (1 + 2, 3) = Q (3, 3)

In Mathematics, a reflection across the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would change from positive to negative. Therefore, a reflection over the x-axis is given by this transformation rule:

(x, y)      →       (x, -y)

(x - 250)^2 + (y + 170)^2 = 180000

The reflected and then translated coordinates of the triangle are R'( 3,2), S'(3,5), and T'( 8, 5).

A sort of symmetry known as reflective symmetry occurs when one half of an object mirrors the other half. It also goes by the name "mirror symmetry."

For instance, both the left and right sides of a human face are typically the same. Most butterflies have identical wings on their left and right sides.

The given points of the triangle are R(3,-4), S(3,-7), and T(8,-7).

The reflected points of the triangle will be:-

R(3,-4) = R'( 3, 4)

S(3,-7) = R'(3,7)

T(8,-7) = R(8, 7)

The translated points by 2 units down will be:-

R'( 3, 4) = R''( 3, 2)

R'(3,7) = S''( 3, 5)

R(8, 7) = T''(8,5)

The matrix must have pivot columns. Otherwise, the equation Ax = 0 would have a free variable, in which case the columns of A would not span R5. Therefore, the correct answer is C.

A pivot column is a column of the matrix that has a non-zero entry in the pivot position and all entries below the pivot are zero. In row echelon form, every row below a pivot column has a zero in the corresponding position. The pivot columns correspond to the linearly independent columns of the original matrix and the number of pivot columns determines the rank of the matrix.

The rank of a matrix is defined as the number of linearly independent columns or rows in the matrix. If the columns of a matrix span Rn, then the rank of the matrix must be equal to n. This means that the matrix must have n linearly independent columns. To ensure that the columns of A span R5, A must have at least 5 pivot columns. If A had fewer pivot columns, then the equation Ax = 0 would have a non-trivial solution, meaning that the columns of A would not be linearly independent and would not span R5.
