The Taylors plan to expand their
podryga [215]

Answer:

A_{2} = 720\ ft^{2}

Step-by-step explanation:

Let w and l be the width and length of the garage.

Let A_{1} and A_{2} be the area of garage at present and new garage.

Given:

The area of the garage at present

A_{1}=80\ ft^{2}

And he planed to tripling the dimensions of the garage.

We need to find the area of the new garage.

Solution:

We know the area of the rectangular garage.

Area=width\times lendth

A_{1}=w\times l

w\times l=80 ---------------(1)

The dimension of the new garage is triple, so the area of the new garage is.

A_{2} = (3\times width)\times (3\times length)

A_{2} = (3\times w)\times (3\times l)

A_{2} = 9\times (w\times l)

Substitute w\times l=80 from equation 1.

A_{2} = 9\times (80)

A_{2} = 720\ ft^{2}

Therefore, the area of the new garage A_{2} = 720\ ft^{2}

A walk-in medical clinic believes that arrivals are uniformly distributed over weekdays (Monday through Friday). It has collecte
allsm [11]

Answer:

The degrees of freedom are given by;

df =n-1= 5-1=4

The significance level is 0.1 so then the critical value would be given by:

F_{cric}= 7.779

If the calculated value is higher than this value we can reject the null hypothesis that the arrivals are uniformly distributed over weekdays

Step-by-step explanation:

For this case we have the following observed values:

Mon 25 Tue 22 Wed 19 Thu 18 Fri 16 Total 100

For this case the expected values for each day are assumed:

E_i = \frac{100}{5}= 20

The statsitic would be given by:

\chi^2 = \sum_{i=1}^n \frac{(O_i-E_i)^2}{E_i}

Where O represent the observed values and E the expected values

The degrees of freedom are given by;

df =n-1= 5-1=4

The significance level is 0.1 so then the critical value would be given by:

F_{cric}= 7.779

If the calculated value is higher than this value we can reject the null hypothesis that the arrivals are uniformly distributed over weekdays

How measure the slope of the line
DerKrebs [107]

Answer:

The slope of a line is measured in the change in y divided by the change in x with 2 points on the same line.

For example, if a line crosses both points (2, 3) and (6, 14) that means the slope would be the change from 3 to 14, which is 11, divided by the change from 2 to 6, which is 4, or 11/4.

Hope this helped!
