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

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:
