Answer:
x = 7
Step-by-step explanation:
y = 14
14 x 2 = 28
Therefore:
3.5 x 2 = 7
<span> we know that the 90 percentile in Z-score is ≈ 1.28 then,
=136 ± 1.28(13.8)
=(118.336 , 153.664)
</span>hope it helps
125/100 = 425/x. first find x. so multiply both sides by 100
so 125=42500/x. now multiply both sides by x
so 125x=42500. divide both sides by 125
so x=340. now, find 65% of 340. to find this, we set up the proportion (like the previous one) 65/100=x/340
we multiply both sides by 100
so 65=100x/340
multiply both sides by 340
so 22100=100x
divide both sides by 100
so x = 221
which is 65% of the number
Pretty sure it would be A
