A linear equation in slope intercept form that passes through the points (-11 -5) and (1 -2) is:

$y=\frac{1}{4}x-\frac{9}{4}$

Step-by-step explanation:

Given:

Explicit formula for sequence

$A(n)=9+(n-1)(-5)$

To find the 7th term we have to put n=7

So,

$A(7)=9+(7-1)(-5)\\=9+(6)(-5)\\=9-30\\=-21$

A linear equation in slope intercept form that passes through the points (-11 -5) and (1 -2) is:

$y=\frac{1}{4}x-\frac{9}{4}$

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary

professor190 [17]

Calculate 7.25% of 4500 = (4500 x 7.25) / 100 = 326.25.

Danielle's base salary = 775

Last week salary = 775

Total earned in a week = 775 + 326.25 = 1101.25

Scientists collect data on the blood cholesterol levels (milligrams per deciliter of blood) of a random sample of 24 laboratory

Ludmilka [50]

Answer: (a) There is a clear outlier in the data.

Step-by-step explanation:

The statement relates that sample= 24

Confidence interval= 80.2 to 89.8.

Now the data does not mention anywhere the standard deviation which is an important parameter in using the t-procedure rather we assume that standard deviation is not known. So, the most worrying part is the skewness and the presence of strong outliers in the t-procedure.

So, the option a) is correct meaning a clear outlier in the data.

Find f-1(x), if f(x) = 3x – 6. Justify your

Sergio039 [100]

Answer: 1/3 (x + 6)

Explanation: given f(x) = 3x - 6.
Let y = f(x) and so y = 3x - 6.
Trade places between x and y.
x = 3y - 6
Solve for y
x + 6 = 3y
y = x + 6/3
Now the new y is the inverse and so y = f-1(x)
f-1(x) = 1/3(x + 6)
