                          200

Answer:

0.22

Step-by-step explanation:

Let assume the number to be reduced be 100

Reducing it by 78% will be:

100 - ( 78% of 100 )

100 - (78/100)×100

100 - 0.78 × 100

100 - 78 = 22

Since the answer is 22. Hence,

22/100 will be the multiplier

0.22 × 100 = 22

The probability that a randomly selected squirrel has a weight less than 3 pounds:  P(x < 3) = 0.0139

What is Probability?

Chance is a branch of mathematics that deals with numerical representations of the probability that an event will happen or that a statement is true. The probability of an event is a number between 0 and 1, where, broadly speaking, 0 signifies the event's impossibility and 1 denotes certainty.

Given,

μ = 4.1

σ = 0.5

∴ P(x < 3) = P(z < (3 - μ) / σ)

= P(z < (3 - 4.1) / 0.5)

= P(z < -1.1/0.5)

P(x < 3) = P(z < -2.2)

P(x < 3) = 0.0139

As a result, P(x 3) = 0.0139 is the probability that a squirrel chosen at random weighs less than 3 pounds.

Answer:

Total no. of cups = 25+5n

Step-by-step explanation:

Given that,

Jayden begins with 25 cups with soil at the greenhouse.

Each day he will fill 5 cups more.

We need to find an algebraic expression to represent the number of cups he will have after n days.

Here, 5 cups increases with number of days and 25 cups remain fix.

Total number of cups after n days = 25 + 5n

Hence, the required answer is "25+5n".

The probability of choosing a frosted marble based on the given data is 0.16

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event (i.e., an event that will never occur) and 1 represents a certain event (i.e., an event that will always occur)

The probability of choosing a frosted marble can be calculated by dividing the number of frosted marbles by the total number of marbles

P(frosted) = number of frosted marbles / total number of marbles

In this case, Malik randomly chose 25 marbles from the bag, so the total number of marbles is 25. He recorded 4 frosted marbles, so

P(frosted) = 4 / 25

Simplifying, we get

P(frosted) = 0.16

the probability is 5/12

To calculate the probability that the sum of the values on two fair six-sided dice is a prime number, we need to determine the number of favorable outcomes (sums that are prime) and the total number of possible outcomes.

First, let's identify the prime numbers that can be obtained as the sum of two dice:

2 (1+1)

3 (1+2, 2+1)

5 (1+4, 2+3, 3+2, 4+1)

7 (1+6, 2+5, 3+4, 4+3, 5+2, 6+1)

11 (5+6, 6+5)

There are 15 pairs whose sum is prime numbers that can be obtained as the sum of two dice.

Next, let's calculate the total number of possible outcomes when throwing two six-sided dice. Each die has 6 possible outcomes, so the total number of outcomes is 6 * 6 = 36.

Therefore, the probability that the sum of the values on two fair six-sided dice is a prime number is:

Number of favorable outcomes / Total number of possible outcomes

= 15 / 36

= 5/12

Therefore, the probability is 5/12

During ATP hydrolysis, the chemical bond that is broken is the phosphoester bond.

ATP hydrolysis is a process in which ATP (adenosine triphosphate) is converted into ADP (adenosine diphosphate) and inorganic phosphate (Pi) through the addition of water. This hydrolysis reaction is catalyzed by enzymes called ATPases. The bond that is broken during this process is the phosphoester bond between the terminal phosphate group and the rest of the ATP molecule.

ATP molecules contain three phosphate groups connected by phosphoester bonds. These bonds are relatively high in energy due to the negatively charged phosphate groups and their repulsion for each other. When ATP is hydrolyzed, a water molecule is added, and the phosphoester bond between the terminal phosphate and the rest of the molecule is cleaved. This releases a considerable amount of energy, which can be utilized by cells for various energy-requiring processes, such as muscle contraction, active transport, and synthesis of macromolecules. The hydrolysis of ATP to ADP and Pi is a crucial step in cellular energy metabolism.

Answer:

\(\sf area \ of \ sector = 94.25 \ ft^2\)

Explanation:

\(\sf area \ of \ sector = \frac{1}{2} r^2 \theta\)

using the formula:

\(\hookrightarrow \sf area \ of \ sector = \frac{1}{2} r^2 \theta\)

\(\hookrightarrow \sf area \ of \ sector = \frac{1}{2} (6)^2 (\frac{5\pi }{3} )\)

\(\hookrightarrow \sf area \ of \ sector = 30\pi\)

\(\hookrightarrow \sf area \ of \ sector = 30(3.14)\)

\(\hookrightarrow \sf area \ of \ sector = 94.25 \ ft^2\)

Answer:

The range of this quadratic function is

-infinity < y ≤ 2.

Using a system of equations, it is found that:

--------------------------

In a triangle, the sum of the interior angles is of 180º, thus:

\(x + y + z = 180\)

The second angle of the triangle  has a measure equal to the sum of two times the other two angles, then:

\(y = 2(x + z)\)

\(x + z = 0.5y\)

Replacing into the first equation, we find the second angle:

\(x + y + z = 180\)

\(0.5y + y = 180\)

\(1.5y = 180\)

\(y = \frac{180}{1.5}\)

\(y = 120\)

The measure of the second angle is of 120º.

Now, working to find the measures of the first and of the third angles:

\(x + z = 0.5y \rightarrow x + z = 60 \rightarrow x = 60 - z\)

The third  angle has a measure equal to ten less than the first angle, then:

\(z = x - 10\)

Since \(x = 60 - z\)

\(z = 60 - z - 10\)

\(2z = 50\)

\(z = \frac{50}{2}\)

\(z = 25\)

And

\(x = 60 - z = 60 - 25 = 35\)

The measure of the first angle is of 35º.

The measure of the third angle is of 25º.

The line integral along the curve C can be evaluated using Green's Theorem, which relates it to a double integral over the region enclosed by the curve.

In this case, the curve C is the boundary of the region enclosed by the parabolas\(y = x^2 and x = y^2\). To evaluate the line integral, we can first find the partial derivatives of the given vector field:

\(F = (3y + 7e^(√x)/2) dx + (10x + 7cos(y^2)) dy\)

Taking the partial derivative of the first component with respect to y and the partial derivative of the second component with respect to x, we obtain:

∂F/∂y = 3

\(∂F/∂x = 10 + 7cos(y^2)\)

Now, we can calculate the double integral over the region R enclosed by the curve C using these partial derivatives. By applying Green's Theorem, the line integral along C is equal to the double integral over R of the difference of the partial derivatives:

∮C F · dr = ∬R (∂F/∂x - ∂F/∂y) dA

By evaluating this double integral, we can determine the value of the line integral along the given curve.

In an observational study, the statement that a cause and effect can be determined is false.

Observational studies simply establish associations between predictor and outcome variables. Observational studies cannot confirm that an association contemplates cause and effect.

In observational studies, confounding variables may explain an observed relationship between predictor and outcome variables.

In an observational study, a cause and effect cannot be determined. Observational studies are used to gather data about a particular population or phenomenon, but they do not allow for the determination of cause-and-effect relationships.

This is because observational studies do not control the variables that are being studied and, therefore, cannot determine the relationship between two variables.

In order to determine cause and effect, a controlled experiment is needed in which the variables are manipulated, and their effects are observed.
