Answer:  x = 32°

Step-by-step explanation:

(3x - 4) + (3x - 8) = 180

3x - 4 + 3x - 8 = 180

6x - 12 = 180

6x - 12 + 12 = 180 + 12

6x = 192

6x ÷ 6 = 192 ÷6

x = 32

Answer:

28 short race volunteers

76 long race volunteers

Step-by-step explanation:

Let :

Short races = a

Long races = b

LAST YEAR:

7a + 8b = 804 - - - - (1)

THIS YEAR:

11a + 5b = 688 - - - (2)

Multiply (1) by 5 and (2) by 8

35a + 40b = 4020

88a + 40b = 5504

Subtract

-53a = - 1484

a = 1484 / 53

a = 28

Put a = 28 in equation (1)

7(28) + 8b = 804

196 + 8b = 804

8b = 804 - 196

8b = 608

b = 76

28 short race volunteers

76 long race volunteers

Answer: 21

Step-by-step explanation: We are given that angle ABC is dilated with center P.

Scale factor=3

Angle A'B'C' is formed after dilation of angle ABC.

Dilation: when a figure is dilated by scale factor a then, the figure shape does not change.

After dilation, the size of figure changes.

The initial figure and the figure obtained after dilation are similar in shape.

When two figures are similar then , the angles of one figure are  congruent to its corresponding angles in other figure and ratio of their corresponding sides are equal.

The measure of angle ABC=21'

After dilation by scale factor 3 then, the measure of angle A'B'C' remains=21'

Because the shape does not change in dilation transformation.

Answer:

x + y + 1

or

xy + y² + 2

or

x² + y² - 1

or

a²b + b³ + 3

Step-by-step explanation:

You can use x and y as the two variables. Then add them to make is x + y (this is already two variables and two terms). Add a constant, say 1. So x + y + 1, now we have three terms with two different variables and one constant.

Or you can also make it xy + y² + 2 or x² + y² - 1 by adding exponents to each of the variable.

You can choose one from the above or you can make your own (it depends on you).

d-4=19d=15

We move all terms to the left:

d-4-(19d)=0

We add all the numbers together, and all the variables

-18d-4=0

We move all terms containing d to the left, all other terms to the right

-18d=4

d=4/-18

Minimum number of tents are 11.

Here,

32 athletes are going camping for the weekend.

3 athletes can sleep in one tent.

We have to find the minimum number of tents.

What is Number system?

A system of writing to express number is called Number system.

Now,

Number of athletes = 32

Number of athletes in one tent = 3

Hence, Minimum number of tents = 32 ÷ 3

We get 11 tents for 32 athletes.

Therefore, Minimum number of tents are 11.

Answer:

The margin of error for a 96% confidence interval is of 0.0114 = 1.14%.

Step-by-step explanation:

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

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

For this problem, we have that:

[tex]n = 400, p = \frac{395}{400} = 0.9875[/tex]

96% confidence level

So [tex]\alpha = 0.04[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.04}{2} = 0.98[/tex], so [tex]Z = 2.056[/tex].

Calculate the margin of error for a 96% confidence interval.

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]M = 2.056\sqrt{\frac{0.9875(0.0125)}{400}}[/tex]

[tex]M = 0.0114[/tex]

The margin of error for a 96% confidence interval is of 0.0114 = 1.14%.
