Since all sides are equal in a pentagon, and there are 5 sides; 60/5 is equal is 12 so each side is 12 feet.

M + w = 253m + 4w = 90 Let's do substitution, first by solving the first equation for m. m = 25 - w Substitute! 3(25 - w) + 4w = 9075 - 3w + 4w = 90w = 15 m = 25 - 15 = 10 Hope this helps!

Answer:

-4.317

Step-by-step explanation:

The z test statistic for testing of 1-proportion can be computed as

$z=\frac{phat-p}{\sqrt{\frac{pq}{n} } }$

We know that

phat=x/n.

We know that x=40 and n=120.

Thus,

phat=40/120=0.3333

p=hypothesized proportion=0.53

q=1-p=1-0.53=0.47

So, required z-statistic is

$z=\frac{0.3333-0.53}{\sqrt{\frac{0.53(0.47)}{120} } }$

$z=\frac{-0.1967}{ 0.04556 }$

z=-4.317.

Thus, the required test statistic value for given hypothesis is z=-4.317.
