A statistician takes several random surveys, each of 50
middle school students, to determine the favorite pizza topping of middle school students. The table shows the mean results from all the surveys.

extra cheese 13
pepperoni 17
pineapple 8
sausage 5
vegetables 7

Which statement is a valid inference that can be made based on the data collected?

1) On average, about 50% of students prefer either extra cheese or pepperoni.

2) On average, about 10% of students prefer sausage.

3)On average, 1/3 of students prefer either pepperoni or pineapple.

4)On average, 1/4 of students prefer either pineapple or vegetables.

Answer: 35°

Step-by-step explanation:

m∠A + m∠B + m∠C  =  180°

40° + 105° + m∠C = 180°

m∠C + 145°  =  180°

Subtract 145° from both sides.

m∠C  =  35°

So, the measure of the missing angle (x) is 35°.

Answer:

25.12

Step-by-step explanation:

circumference is 2 x π x r or π x d

so 8 x π would give you 25.12

Answer:

C.

Step-by-step explanation:

The formula for the circumference is:

C = [tex]\pi[/tex]d

C = (3.14)(8)

C = 25.12

The circumference of the circular shaped rug would 25.12 feet.

the bigger the number then it the nearest to the tens and it smaller its easy i use common sense

Answer:

m∠1= 31°  m∠2=149°

m∠3= 31° m∠4=149°

m∠6=31° m∠7=149°

m∠8=31°

Step-by-step explanation:

m∠1 + m∠5= 180°

m∠1=180-149

m∠1=31°

m∠2+m∠1=180

m∠2=149°

m∠6=31°

m∠3=m∠1 (corresponding angle)

m∠3=31° m∠8=31° (vertical angle)

m∠4=149° m∠7=149° (vertical angle)

Answer:

or 2/3

Step-by-step explanation:

because two flips out of 3 all together is 2/3

let's write 2*2*2*2*2*2*2*2*2 in exponential form.

Notice 2 has been multiplied times itself 9 times.

Basic exponential notation:-

[tex]\sf{2*2=2^2}[/tex]

[tex]\sf{2*2*2=2^3}[/tex]

[tex]\sf{2*2*2*2=2^4}[/tex]

You should notice a pattern.

This is the pattern:-

The number of times 2 has been multiplied times itself is the exponent.

In this case, we multiplied 2 times itself 9 times.

Hence, the answer is

[tex]\bigstar{\boxed{\pmb{2^9}}}[/tex]

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I'll comment and/or edit my answer :)

Answer:

Part A-      Surface area = 150cm squared

Step-by-step explanation:

First you find the area of one side of the cube-

side length (5) x side length (5) = area (25)

25 is the area of one side of the cube.

Then you multiple the area of one side (25) by the amount of sides that there are (6)-

25 x 6 = 150

Answer:

6 = W + 2

Explanation:

The reason is since the hangar balance is "balanced" and there are six units on the left side and only 2 on the right (minus the variable weight), that means that the left weight is equal to the right and therefore 6u=w+2u.

Answer:

The width of the scale model is 33 inches.

Step-by-step explanation:

This question is solved making a relation with the scale model. In the scale, 3 inches are worth 11 real feet.hope this help you.if you need any more help let me now and I mite be abal to help you.

The actual gallery comes to be 84 feet long.

A scale factor is a factor by which the dimension of an object is enlarged or diminished.

Scale of 2 inches = 7feet.

So, a scale of 1 inch = 7/2 feet

So, scale factor =7/2

So, a scale of 24 inches = 24*scale factor= 24*7/2 = 84 feet

So, the actual length of the gallery = 84 feet

Therefore, the actual gallery comes to be 84 feet long.
