solution:
a score of 92 has z score of
z=\frac{x-μ}{σ}=\frac{92-71}{5}=1.40
a score of 688 has z score of
z=\frac{x-μ}{σ}=\frac{688-493}{150}=1.30
a score of 92 is better because its z score is higher
95 + 68,95 = 163,95
6,1% de 163,95 =
(6,1*163,95)/100 =
10,00095 ~ $10,00
Step-by-step explanation:
You are finding the whole
0.7 × 20 = 14
or
70% of 20 = 7/10 x 20 = 7/10 x 20/1 = 140/10
140/10
140/10 = 14/1
The minimum number of questions he need to do are 14
I'm not sure if you are finding the part or the whole
