Answer:
We need an SRS of scores of at least 153.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find M as such
In which is the standard deviation of the population and n is the size of the sample.
How large an SRS of scores must you choose?
This is at least n, in which n is found when . So
Rounding to the next whole number, 153
We need an SRS of scores of at least 153.

Answer:
I love this app welcome to the club
Step-by-step explanation:
3x+5x=25xy+x-4
8x=25xy+x-4
8(-3)=25(-3)(5)+(-3-4)
-24=25(-15)+(-7)
-24= -375-7
-24= -382
if the question is right that you asked, i mean the = sign then the solution is will be come like this but if there is no = sign then you can get the solution by subtracting -24-382= -406
