3 0

we know that

To convert the decimal as fraction in this problem, multiply and divide by one hundred

0.07=0.07*\frac{100}{100}=\frac{0.07*100}{100}=\frac{7}{100}

therefore

the answer Part a) is

the decimal as fraction is equal to \frac{7}{100}

Part b)

we know that

1 dollar is equal to 100 cents

1 cent is equal to 0.01 dollars

the tax is equal to 0.07 dollars

so

by proportion

\frac{100}{1} \frac{cents}{dollar}=\frac{x}{0.07} \frac{cents}{dollars}\\ \\x=100*0.7\\ \\x=7\ cents

the tax is equal to 7 cents

therefore

<u>the answer part b) is </u>

There are 7 cents of tax in each dollar

Find the slope of the line that passes through the points (0,-11) and (8,-8).
Korolek [52]

To find the slope of a line, we can use the following formula:

\displaystyle \large{m =  \frac{y_2 - y_1}{x_2 - x_1} }

m-term stands for slope or gradient. The formula is useful whenever you want to find a slope of two points.

Let these be the following:

\displaystyle \large{(x_1,y_1) = (0, - 11)} \\  \displaystyle \large{(x_2,y_2) = (8, - 8)}

Substitute the points in formula:

\displaystyle \large{m =  \frac{ - 8 -( - 11)}{ 8 - 0} }

Negative multiply negative always come out as positive.

\displaystyle \large{m =  \frac{ - 8  +  11}{ 8 - 0} } \\  \displaystyle \large{m =  \frac{ 3}{ 8 } } \\

Since m stands for slope, we can say that:

\displaystyle  \large \boxed{ \tt{slope  =  \frac{3}{8} }}

GREYUIT [131]
<h2>Answer:</h2>

29%

<h2>Explanations:</h2>

Probability is the likelihood or chance that ab event will occur. Mathematically;

Probability = Expected/Total

From the given table, the total number of male student is the total outcome as shown:

Total outcome = 4 +6+ 2 + 2

Total outcome = 14

If a male freshmen is selected at random, the expected outcome will be 4.

Determine the probability

\begin{gathered} Pr(Freshman\text{ \mid Male})=\frac{Male\text{ freshmen}}{Total\text{ male studnt}} \\ Pr(Freshman\text{ \mid Male})=\frac{4}{14} \\ Pr(Freshman\text{ \mid Male})=0.2857\times100 \\ Pr(Freshman\text{ \mid Male})\approx29\% \\  \end{gathered}

Hence the probability that the male student is freshman is approximately 29%
