3. 5-6x = 17 - 8x what’s the answer
Rufina [12.5K]

Answer:

x=6

Step-by-step explanation:

5-6x=17-8x                  5-6x=17-8x

5-6(6)=17-8(6)     or     5+2x=17                 added 8x to both sides

5-36=17-48                  2x=12                    subtracted 5 from both sides

-31=-31                          x=6                       divided both sides by 2

(please mark brainliest, i need it to get to next lvl <3 )

The scores of individual students on the American College Testing (ACT), college readiness assessment, have a Normal distributio
Luba_88 [7]

Answer:

The standard deviation of the sampling distribution of the sample mean score for a random sample of 36 students is 1.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

\sigma = 6, n = 36

Then, by the Central Limit Theorem:

s = \frac{\sigma}{\sqrt{n}}

s = \frac{6}{\sqrt{36}}

s = 1

The standard deviation of the sampling distribution of the sample mean score for a random sample of 36 students is 1.

A state park has two pools. The olympic size pool holds 8.12 x 105 gallons of water and the smaller pool holds 5.27 x 105 gallon
mr_godi [17]
First you need to work out what (8.12×105=?) Then (5.27×105=?) And add them together so (8.12×105)+(5.27×105)=the answer to your question
