Check the picture below.

\bf \textit{volume of a pyramid}\\\\
V=\cfrac{1}{3}Bh\qquad 
\begin{cases}
B=area~of\\
\qquad its~base\\
h=height\\
------\\
B=\stackrel{14\times 14}{196}\\
h=24
\end{cases}\implies V=\cfrac{1}{3}(196)(24)

A medical website states that 40% of U.S. adults are registered organ donors. A researcher believes that the proportion is too h
alexgriva [62]

Answer:

Pvalue = 0.193

There is not enough evidence to conclude that the proportion of registered organ donors is less than 40%

Step-by-step explanation:

H0 : p = 0.4

H1 : p < 0.4

Test statistic :

z=pˆ−p/√p(1−p)/n

pˆ = 74 / 200 = 0.37

Z = (0.37 - 0.40) / √(0.40(1 - 0.40) / 200

Z = - 0.03 / √0.0012

Z = - 0.03 / 0.0346410

Z = - 0.866

Test statistic = -0.866

The Pvalue :

P(Z < -0.866) = 0.193

α - level = 0.05

If Pvalue < α ; Reject H0

Since Pvalue > α ; There is not enough evidence to conclude that the proportion of registered organ donors is less than 40%

Tasha believes that she can rewrite the difference of 120 minus 36 as a product of the GCF of the two numbers and the difference
xz_007 [3.2K]

Answer:

GCF = 12

For the values 36, 120:

Solution by Factorization:

The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36

The factors of 120 are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

Then the greatest common factor is 12.



Pair Share:

The GCF of 120 and 36 is ======> 12

so, 120 – 36 can be written as:

12 × 10 – 12 × 3, which is 12 × (10 – 3) or 12 × 7.


Answer: ========> Therefore, Tasha is correct






Hope that helps!!!! : )
