step-by-step explanation:

Irene has 49 Books, and Alejandro has 24 books.

Let's assume that Irene has x books, and Alejandro has y books. According to the given information, we can form the following equations:

1. Irene has twice as many books as Alejandro plus 1:

  x = 2y + 1

2. The total number of books between Irene and Alejandro is 73:

  x + y = 73

We can now solve this system of equations to find the values of x and y.

Substituting the value of x from equation (1) into equation (2), we have:

(2y + 1) + y = 73

3y + 1 = 73

3y = 72

y = 24

Now, we can substitute the value of y into equation (1) to find x:

x = 2(24) + 1

x = 49

Therefore, Irene has 49 books, and Alejandro has 24 books.

To verify our solution, we can check if the sum of their books equals 73:

49 + 24 = 7

So, our solution is correct.

In conclusion, Irene has 49 books, and Alejandro has 24 books.

When a quantity increases by 25%, the new quantity becomes 100% + 25% = 125% of the original quantity.

After the first year, the quantity has increased to 125% of its original value. After the second year, it increases an additional 25%, making the new value 125% + (25% of 125%) = 156.25% of the original value. Finally, after the third year, it increases by another 25%, making the new value 156.25% + (25% of 156.25%) = 195.3125% of the original value.

So the quantity has increased by 195.3125% - 100% = 95.3125% over the three-year period. Therefore, the combined percentage growth p over the three-year period is 95.3125%.

In order to create 728 millilitres of the medication, 273 millilitres of component A are required.

A compound in chemistry is a material comprised of two or more separate chemical elements mixed together in a certain proportion. Chemical connections that are challenging to break are created when the elements interact with one another.

Compound A:Compound B ratio in the medication is 3:5. In other words, there are 3 millilitres of compound A and 5 millilitres of compound B for every 3+5=8 millilitres of the medicine.

We may set up a percentage using the ratio of compound A to the total volume of the medicine to determine how much compound A is required to make 728 millilitres of the drug:

3 ml x 3 ml x 3 ml

-------- = ----------

728 ml total, 8 ml overall

If we cross-multiply, we obtain:

8(x) = 3(728)

To find x, we use the formula x = 3(728)/8 = 273

273 milliliters of compound A are needed to make 728 milliliters of the drug.

What are proportions?

In mathematics, a proportion is a statement that two ratios are equal. It expresses the relationship between two or more quantities that are directly proportional to each other. A proportion can be represented as an equation of the form:

a/b = c/d

To determine the amount of compound A needed to make 728 milliliters of the drug, we need to use the given ratio of 3 milliliters of compound A to 5 milliliters of compound B.

Let's start by finding the ratio of compound A to the total amount of ingredients (A+B) in the drug:

3 : (3+5) or 3:8

This means that for every 8 milliliters of the drug, 3 milliliters of compound A are used.

To find out how many milliliters of compound A are needed for 728 milliliters of the drug, we can set up a proportion:

3/8 = x/728

where x represents the amount of compound A needed.

To solve for x, we can cross-multiply:

8x = 3*728

8x = 2184

x = 273

Therefore, 273 milliliters of compound A are needed to make 728 milliliters of the drug.

Answer:

x = 8

Step-by-step explanation:

There are two ways of answering this:

1.)Supplementary Angles/Linear pair:

(5x- 15) + (20x - 5) = 180°

25x - 20 = 180

25x - 20 +20 = 180 + 20

25x = 200

x = 8

2.) Vertical angles theorem:

(5x - 15) = (3x + 1)

5x - 3x -15 + 15 = 3x - 3x + 1 +15

2x = 16

x = 8

At the same rate as his 100-meter freestyle swim in the 2012 Olympics, Nathan Adrian could have completed one loop of a 25-meter pool in 11.88 seconds.

The idea of proportionality can be applied. The time it would take Nathan Adrian to complete one lap in a 25-meter pool is known to be 47.52 seconds for the 100-meter freestyle. Since the tempo is constant while the distance varies, we can establish a ratio:

100 meters / 47.52 seconds = 25 meters / x seconds

where x is the unknown time for one lap in the 25-meter pool.

To solve for x, we can cross-multiply:

100 meters * x seconds = 47.52 seconds * 25 meters

100x = 1188

Dividing both sides by 100, we get:

x = 11.88 seconds

Answer:

[0.6969, 0.7695]

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.

\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)

In which

z is the z-score that has a p-value of \(1 - \frac{\alpha}{2}\).

They randomly survey 401 drivers and find that 294 claim to always buckle up.

This means that \(n = 401, \pi = \frac{294}{401} = 0.7332.

90% confidence level

So \(\alpha = 0.1\), z is the value of Z that has a p-value of \(1 - \frac{0.1}{2} = 0.95\), so \(Z = 1.645\).  

The lower limit of this interval is:

\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.7332 - 1.645\sqrt{\frac{0.7332*0.2668}{401}} = 0.6969\)

The upper limit of this interval is:

\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.7332 + 1.645\sqrt{\frac{0.7332*0.2668}{401}} = 0.7695\)

The 90% confidence interval for the population proportion that claim to always buckle up is [0.6969, 0.7695]

{-3, -1, 0, 1, 2}

When creating a scatterplot, it is important to carefully consider which variable to place on the vertical and horizontal axes.

The vertical axis is commonly used to represent the response or dependent variable, while the horizontal axis is used for the explanatory or independent variable.

However, when dealing with a categorical variable, there is no inherent order or numerical relationship between the categories. Thus, it does not make sense to use either axis as a response or explanatory variable. In this case, the categorical variable should be placed on either axis based on what makes the most sense for the data being displayed.

If there is an explanatory variable and a response variable, the explanatory variable should be placed on the horizontal axis and the response variable on the vertical axis. This is because the explanatory variable is usually the variable that is being manipulated or controlled, while the response variable is the one that is being measured or observed.

Overall, the placement of variables on the axes of a scatterplot should be based on the nature of the data being displayed and the relationship between the variables being studied.

Answer:

The ordered pair (-3, 12) DOES NOT satisfy the equation.

Step-by-step explanation:

Given the function

\(y=-3x+2\)

Let us substitute all the values to check which points satisfy the function.

FOR (1, -1)

y = -3x+2

substitute x = 1, y = -1

-1 = -3(1) + 2

-1 = -3+2

-1 = -1

TRUE!

Thus, the ordered pair (1, -1) satisfies the equation.

FOR (4, -10)

y = -3x+2

substitute x = 4, y = -10

-10 = -3(4) + 2

-10 = -12+2

-10 = -10

TRUE!

Thus, the ordered pair (4, -10) satisfies the equation.

FOR (-2, 8)

y = -3x+2

substitute x = -2, y = 8

8 = -3(-2) + 2

8 = 6 + 2

8 = 8

TRUE!

Thus, the ordered pair (-2, 8) satisfies the equation.

FOR (-3, 12)

y = -3x+2

substitute x = -3, y = 12

12 = -3(-3) + 2

12 = 9+2

12 = 11

L.H.S ≠ R.H.S

FALSE!

Thus, the ordered pair (-3, 12) DOES NOT satisfy the equation.

Therefore, the ordered pair (-3, 12) DOES NOT satisfy the equation.

The table on the number of tickets and total cost is:

Number of tickets                 1                        5                 10               15

Total cost                          $ 10. 75             $ 13.75       $17.50        $ 21. 25

The number of tickets that Sam can buy when he has $ 37 is:

= (Amount to spend - Cost of admission ) / Cost per ticket

= ( 37 - 10 ) / 0.75

= 36 tickets

The rate of change is therefore the $ 0.75 charged per ticket per event.

The number of tickets for $ 10. 75 is:

= ( Total cost - Cost of admission ) / cost per ticket

= ( 10. 75 - 10 ) / 0.75
