would you choose to use a hundred chart to solve 90- 80? why or why. not ? if not. which strategy would work better?

1 answer:

5 0

I would use a tens chart because both numbers are multiples of 10, and there both under 100, so it would work out better if u use a tens chart, since the numbers are in the tens place and would give u a product of 10.

i hope this helps u <span />

The scores of a high school entrance exam are approximately normally distributed with a given mean mu = 82.4 and standard deviat

Slav-nsk [51]

The percentage of the scores that are between 75.8 and 89 is; 95%

<h3>How to find the percentage from z-score?</h3>

We are given;

Population mean; μ

Standard deviation; σ = 3.3

Thus;

z-score for a mean score of 75.8 is;

z = (75.8 - 82.4)/3.3

z = -2

z-score for a mean score of 89 is;

z = (89 - 82.4)/3.3

z = 2

From online p-value from z-score calculator, the p-value between both z-scores is;

p-value = 0.9545 = 95.45%

Approximating to the nearest percent = 95%

A certain city divides naturally into ten district neighborhoods. How might a real estate appraiser select a sample of single-fa

Marysya12 [62]

Answer:

An appropriate method is to generate a simple random sample of all single-family homes in the city or a stratified random sample by taking a simple random sample from each of the ten district neighborhoods.

Step-by-step explanation:

Since, the city is very large and it is divided into ten districts. So, collecting sample from one district or any particular are did not give the correct estimate of whole city. So, the appropriate method to collect sample is taking the sample randomly from each district and this type of sampling method is called Stratified Sampling.
