I believe its B. Stratified because the owner had to speak to ten individuals, meaning he divided it into smaller groups.

Answer:

b) Stratified

Step-by-step explanation:

Given: A mattress store boasts 4 out 5 sleepers in a commercial that airs locally. I talked to the owner and found out he only talked to ten people.

This is not regressive as regressive got two variables dependent and independent

This is not variation as no variation is explained in the sample

This is not replication, as replication involves repitition of experiments a number of times.

This is not blocking because nothing is blocked in this

So this comes under

b) Stratified

A bag contains yellow marbles and red marbles, 23 in total. The number of yellow marbles is 4 less than 2 times the number of re
Orlov [11]
First let’s express the total number of marbles as such:
y(yellow marbles) + r(red marbles)=23; y+r=23

now let’s express the relation of yellow marbles to red marbles:
y=2r(2 times red marbles) - 4(4 less marbles); y=2r-4

since we figured out what y equals, we can plug into the first equation we created:
(2r-4)+r=23

now solve for r:
2r-4+r=23
combine like terms
3r-4=23
add 4 to both sides
3r=27
divide both side by 3
r=9

plug r back into first equation and solve for y:
y+9=23
subtract 9
y=14

there are 9 red marbles and 14 yellow marbles!

Solve for the volume of the following figure.
Olenka [21]

Answer:

96\pi \: or \: 301.59

rounded to the nearest hundredth

Step-by-step explanation:

use the pythagorean theorem to find the height of the cone

{a}^{2}  +  {6}^{2}  =  {10}^{2}

you get a = 8

the formula for the volume of a cone is

\pi \:{r}^{2}  \frac{h}{3}

plug in 6 for the radius and 8 for the height. then solve

The measure of spt is b. The measure of tpr in s five more than two times spt. The measure of qps is twelve less than eight time
Marrrta [24]

Hello.

In your question, we can see that the points Q, P, and R can be assumed that they are in a straight line, meaning that the angle measures will add up to 180 (think of half a circle, which is 360 degrees).

This means that every angle added up will add up to 180 degrees.

Meaning we can set up the below equation:

(8b-12)+(b)+(2b+5)=180

8b-12+b+2b+5=180

11b-7=180

11b=187

b=17

After finding b, we can plug it back in to each expression for each angle measure.

∠QPS = 8b-12=8(17)-12=124

∠SPT = b=17

∠TPR = 2b+5=2(17)+5=39

Hope this helps!

horsena [70]
The formula for circumference is πd. 
Diameter is 2r. 
5 x 2 = 10 
Use 3.14 for π. 
10 x 3.14 = 31.4 yards
