Answer:

Choice C. 5\frac{3}{4}feet^{2}

Step-by-step explanation:

Surface Area

A = 2lw + 2lh + 2wh

l = 2ft

w = \frac{3}{4}

h = \frac{1}{2}

A = 2(2)(\frac{3}{4}) + 2(2)(\frac{1}{2}) + 2(\frac{3}{4})(\frac{1}{2})

A = 3 + 2 + \frac{3}{4}

A = 5\frac{3}{4} feet^{2}

Find the additive inverse of 9/10 need help
frosja888 [35]

The Additive inverse only works when you add a to its oppositie leaving a sum of 0

For example, says 5 represents a.

5 + b = 0

B, is 5's additive inverse: -5

The reciprocal of 9/10, however, is 10/9

A consumer advocacy group wants to determine whether there is a difference between the proportions of the two leading automobile
podryga [215]

Answer:

The answer is "0.3206".

Step-by-step explanation:

H_0: p_1 = p_2\\\\H_a: p_1 \neq  p_2\\\\\hat{p_1} = \frac{X_1}{N_1} = \frac{53}{400} = 0.1325\\\\\hat{p_1}= \frac{X_2}{N_2} = \frac{78}{500}= 0.156\\\\\hat{p} = \frac{(X_1 + X_2)}{(N_1 + N_2)} = \frac{(53+78)}{(400+500)} = 0.1456

Testing statistic:

z = \frac{(\hat{p_1}- \hat{p_2})}{\sqrt{(\hat{p} \times (1-\hat{p}) \times (\frac{1}{N_1} + \frac{1}{N_2}))}}

=\frac{(0.1325-0.156)}{\sqrt{(0.1456\times (1-0.1456)\times (\frac{1}{400} + \frac{1}{500}))}}\\\\ = -0.99

Calculating the P-value Approach

\text{P-value}= 0.3206
