Me with this, anything . will give you

For this problem, we can refer to the slope formula . This describes the rise over run, change in x over y. We know that the y axis represents the dependent variable and that the x axis represents the independent variable. To put this in the equation, note the use of the word 'per' in this question. If she earns 5 dollars per hour of babysitting, then this means that the amount she earns depends on the number of hours she works. To put this numerically:

Think of the line that separates the dividend and divisor as the word 'per'. The slope of this line would be 5x, since y increases by five every time x increases by one. This means that your slope is .

We are still not completely finished. Notice the fact that she is paid an additional $3 for her transportation. This means that the y value for this line does not start out from 0. Before working any hours at all, there were 3 dollars, which is called the equation's y intercept. Your complete equation will be:

Now that it's complete, all there's left to do is plug in the values for hours worked.

3 hours:

-->

--->

She will earn $18 dollars for 3 hours.

8 hours:

-->

--->

She will earn $43 in 8 hours.

Hope this helped.

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
