A School Board Randomly Samples 80 Students To Determine Their Opinion On Requiring School Uniforms For

Answers

Answer 1

Answer: 900

Step-by-step explanation:

If 24 out of 80 students are undecided, that is 24/80, or 3/10 (0.3).

To find how many would be undecided out of 3,000 students, multiply 3/10 by 3,000/1, and you get 900, which is your answer

Answer 2

Answer:

900

Step-by-step explanation:

A school board randomly samples 80 students to determine their opinion on requiring school uniforms for the next school year. The table shows the results of the survey.

If there are 3,000 students in the district, how many students do you expect to be undecided about school uniforms?

we can solve with an equation

80 : 24 = 3000 : x

x = 24 * 3000 : 80

x = 900

a sample of 500 schools in a state results in an average number of students per grade level of 178.6 students, with a margin of error of 45.2 if there are 3250 high schools in the state, what is the estimated number of students per grade level?​

Answers

To estimate the number of students per grade level in the state, we can use the sample average and the margin of error to construct a confidence interval.

The margin of error is given as 45.2, which means that we can be 95% confident that the true population average number of students per grade level falls within the range of the sample average plus or minus the margin of error.

So, the confidence interval is:

178.6 ± 45.2

To estimate the population average number of students per grade level, we can take the midpoint of the confidence interval:

(178.6 + (178.6 - 45.2)) / 2 = 311.6

Therefore, the estimated number of students per grade level in the state is 311.6

Please help, I will grant the 1st person to answer correctly brainliest.

Answers

Answer: -1/2

Step-by-step explanation:

1. We know that -2 1/3 is also equal to -7/3, because we can multiply the denominator by the main number, and add the numerator.

2. We can do the same with 4 2/3, which would be 14/3.

3. Now, we are left with -7/3 divided by 14/3.

4. To make this easier, we can flip flop the 14/3 so we can multiply instead of divide, which leaves us with -7/3 x 3/14.

5. -7/3 x 3/14 = -21/42

6. We can simplify this to -1/2.

The translation used to create the image include the following: A. 5 units down.

What is a translation?

In Mathematics and Geometry, the translation of a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image;

g(x) = f(x + N)

Conversely, the translation a geometric figure downward simply means subtracting a digit from the value on the positive y-coordinate (y-axis) of the pre-image; g(x) = f(x) - N.

Based on the information provided, we have:

(x, y)                               →                  (x + h, y + k)

(1, -1)                              →                   (1, -6).

1 + h = 1

h = 1 - 1

h = 0

-1 + k = -6

k = -6 + 1

k = -5.

The circle graph describes the distribution of preferred music from a sample of 400 randomly selected middle school students.

a circle graph titled preferred music, with five sections labeled rock 13 percent, hip hop 25 percent, pop 35 percent, classical 13 percent, and jazz 14 percent

Which of the following conclusions can we draw from the circle graph?

Pop is the preferred music for 35 students.
Jazz is the preferred music for 56 students.
Together, Hip Hop, Rock, and Jazz are the preferred music for less than half the students.
Together, Hip Hop and Pop are the preferred music for 260 students.

Answers

Answer:

Step-by-step explanation:

(i) Number of people who are into classical music =10%

10% of pie chart =20 people.

1% ⇒ 10/20 ×100

and 100% ⇒ 10/20 ×100 × 100/ 100

​⇒200 people.

(ii) Light chart represent maximum number as it is 40% of total. ∴ Light music is liked by maximum people.

(iii)

Number of CD's of classical music ⇒ 100/10 × 1000(10%) =100

umber of CD's of semi classical music = 100/20 × 1000(20%) =200

just like that 30% is 300, 40% is 400.

The price of a technology stock was $9.79 yesterday. Today, the price fell to $9.66. Find the percentage decrease. Round your answer to the nearest tenth of a percent.

Answers

Answer: 1.3%

Step-by-step explanation:

The percentage decrease can be found using the formula:

percentage decrease = [(original value - new value) / original value] x 100%

Substituting the given values:

percentage decrease = [(9.79 - 9.66) / 9.79] x 100%

percentage decrease = 1.33%

Rounding to the nearest tenth of a percent, the percentage decrease is 1.3%.

Answer: hope this helps ♡

The percentage decrease is 1.33%.

Step-by-step explanation:

Percentage decrease: dividing the value by the total value and then multiplying it by 100

Total value: $9.79          Value: $9.79 - $9.66 = 0.13

[tex]\frac{0.13*100}{9.79}[/tex]  =

A. 1.99

First, we need to arrange the numbers in order:

0.5, 0.8, 1.3, 1.5, 1.9, 2.0, 2.4, 2.7, 3.2, 3.6

There are 10 numbers in the list, so the median is the middle value. In this case, the middle values are 1.9 and 2.0. To find the median, we take the average of these two numbers:

(1.9 + 2.0) / 2 = 1.95

Therefore, the median drying time is 1.95 hours, option B.

B. 1.95 because (1.9+2.0)/2= 1.95

Triangle ABC is a scale drawing of Triangle XYZ, as shown.
Based on the information shown in these triangles, which of the following is a true statement?

A) The length of side XZ is 11.5.
B) The length of side XZ is 28.
C) The measure of angle A is equal to the measure of angle Z.
D) The measure of angle A is not equal to any of the angle measures of Triangle XYZ.

Answers

Answer: B the side length of XZ is 28

Step-by-step explanation:

to find the scale factor, one of the methods is to divide the side length of one triangle by the same side length of the other triangle.

for example with this problem, the length of XY is 42 while side length AB is 12. 42/12 is 3.5. we know that the side length that corresponds with XZ is 8 so multiply it by 3.5 to get the answer of 28.

Answer:

B

Step-by-step explanation:

Since we know that triangle XYZ is a scale model of ABC then if we find the amount XYZ is bigger then ABC then we can find the answer. Line CB is the corresponding line to ZY and ZY is 3.5x greater then CB. Apply the same logic to AC and we get 8*3.5=ZX 8*3.5=28 so ZX=28.
