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

-3(5)^2-(-2)(-8) simplify
avanturin [10]

To do this, we're going to use the order of operations (PEMDAS):

P - Parentheses

E - Exponents

M - Multiplication

D - Division

A - Addition

S - Subtraction

First let's do parentheses, there isn't anythig in parentheses we need to simplify, so we can skip this step.

Next let's look for exponents. I see we have a 5^2 so let's replace that with 5^2=25:

-3(25)-(-2)(-8)

Now let's look for multiplcation. We know that things that are right next to eachother in parentheses represent multiplcation, so let's simply this more:

-3(25)=-75

(-2)(-8)=16

-75-16

And now we're left with a simple problem we know how to solve.

Answer: -91

Hope this helps!

Xanthe and Sarah do some fundraising for their local nursing home. Together they raised $$$302. If Xanthe raised $$$102 more tha
Dimas [21]

Given :

Xanthe and Sarah together raised $302 .

If Xanthe raised $102 more than Sarah .

To Find :

The amount raised by Sarah .

Solution :

Let , amount raise by Sarah is x .

So , by the relation given , price raised by Xanthe is 102 + x .

Now , sum of their amount raised is :

x+(x+102)=302\\\\2x=302-102\\\\x=\$100

Therefore , the amount raised by Sarah is $100 .

Hence , this is the required solution .

HELP ASAP FOR BRAINLIEST: The mean score for a standardized test is 1700 points. The results are normally distributed with a sta
WITCHER [35]

Answer:

Step-by-step explanation:

Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = test reults

µ = mean score

σ = standard deviation

From the information given,

µ = 1700 points

σ = 75 points

We want to the probability that a student will score more than 1700 points. This is expressed as

P(x > 1700) = 1 - P(x ≤ 1700)

For x = 1700,

z = (1700 - 1700)/75 = 0/75 = 0

Looking at the normal distribution table, the probability corresponding to the z score is 0.5

P(x > 1700) = 1 - 0.5 = 0.5

Hurry please. How many triangles can be constructed with angle measurements ​ 90°,45°,50° ​ ?
Lelechka [254]
Since the sum of the measures of the angles exceed 180 degrees, 90 + 45 + 50 = 185 degrees, these measurements cannot make a triangle.
