9y+68+ 5y= 180
14y+68= 180
-68 -68
14y= 112
Y= 8
Now that we know what y is, we can plug it into the equation for angle B and find its actual angle measurement.
9(8)+ 68= 72+ 68= 140
So its 140 degrees.

Answer:

Step-by-step explanation:

As sample size increase the variability of the estimate of the proportion would decreases ( reduces)

The formula of variance of the estimator of the proportion is as

$
Var(\hat p)=\frac{p*(1-p)}{n}
$

Since the denominator of the formula of the variance of sample proportion is n

so as n increase the variance of it decrease.

The center of the estimate of proportion would same

Because $E(\hat p)=p
$

which does not affect the value of n ( sample size).
