Answer:

The pooled estimate is given by the following formula:

\hat p= \frac{x_1 +x_2 }{n_1 + n_2}

And replacing we got:

\hat p= \frac{42+45}{100+100}= \frac{87}{200}= 0.435

Step-by-step explanation:

We have the following info given:

n1 = 100,

n2 = 100,

x1 = 42,

x2 = 45

The pooled estimate is given by the following formula:

\hat p= \frac{x_1 +x_2 }{n_1 + n_2}

And replacing we got:

\hat p= \frac{42+45}{100+100}= \frac{87}{200}= 0.435

A cellular family phone plan cost $49 per minute plus five cents per minute of long distance service. Write an equation for the
miskamm [114]

The equation for monthly payment is b = 49.05M.

<u>SOLUTION:</u>

Given, a cellular family phone plan cost $49 per minute plus five cents per minute of long distance service. We have to write an equation for the monthly payment b when M minutes of long distance service are used.

Now, given that,

\begin{array}{l}{\text { Monthly payment = } \$ 49 \text { per minute plus five cents per minute of long distance }} \\\\ {\Rightarrow \$ 49 \times \text { number of minutes }+\$ 0.05 \times \text { number of minutes of long distance }} \\\\ {\Rightarrow \mathrm{b}=49 \times \mathrm{M}+0.05 \times \mathrm{M} \rightarrow \mathrm{b}=49 \mathrm{M}+0.05 \mathrm{M} \rightarrow \mathrm{b}=49.05 \mathrm{M}}\end{array}

<em>Equation:</em>

An equation is a statement that the values of two mathematical expressions are equal <em>(indicated by the sign =)</em>
