Tresset [83]

Answer:

2.49

Step-by-step explanation:

Given X= 58

N = 175.

P = 25% = 0.25.

$P' = \frac{X}{N} = \frac{58}{175} = 0.3314\\Z = \frac{P'-P}{\sqrt{\frac{pq}{N} } }$

Now plugging the values we get

$= \frac{0.3314-0.25}{\sqrt{\frac{0.25\times0.75}{175} } }$

=2.49

Answer:

4m² + 28m

A. Yes

Step-by-step explanation:

12m(3m+21) = 3(4m)[3(m+7)]

= 9(4m)(m+7)

= 9(4m²+28m)

Since 9 is a factor, it is divisible by 9

Algebra I

Average Rate of Change: $\displaystyle \frac{f(b) - f(a)}{b - a}$

Step-by-step explanation:

Step 1: Define

Interval -1 ≤ x ≤ 3

a = -1, b = 3

f(a) = f(-1) = 4

f(b) = f(3) = -4

Step 2: Find Average

Substitute in variables [ARC]: $\displaystyle \frac{f(3) - f(-1)}{3 + 1}$
Substitute: $\displaystyle \frac{-4 - 4}{3 + 1}$
[Fraction] Subtract/Add: $\displaystyle \frac{-8}{4}$
[Fraction] Divide: $\displaystyle -2$
