If y + 2q = 15, q + 2p = 5 and p + 2y = 7, then ﬁnd<br> the value of p + q + y.

notsponge [240]

$y+2q=15\\
y=15-2q\\\\
p+2y=7\\
p+2(15-2q)=7\\
p+30-4q=7\\
-3q+30=7\ \ \ |Subtract\ 30 \\
-3q=-23\ \ \ |Divide\ by\ -3\\
q=\frac{23}{3}\\\\
y=15-2q=15-2(\frac{23}{3})=15-\frac{29}{3}=15-7=8\\\\
p=7-2y\\
p=7-2*8\\
p=7-16=-9\\\\
\textbf{p+q+y=}-9+\frac{23}{3}+8=-1+7\frac{2}{3}=\boxed{6\frac{2}{3}}

Help me pretty please <3 (brainliest)

Answer:

The value is 0.025

Step-by-step explanation:

We get the z-score that is equal to the given value

Mathematically we have this as:

z-score = (x-mean)/SD

x = 93

mean =79

SD = 7

So we have the z-score as;

z-score = (93-79)/7 = 14/7 = 2

So we want to calculate the probability equal to the calculated z-score value of 2

Using the standard normal distribution table, we have this value as;

1 - 0.975= 0.025
