Answer:

-7x - 2

Step-by-step explanation:

First, find the new slope that is perpendicular.

1/7 -> 7 -> -7

So far, we have -7x + b. (we use mx + b)

Since you asked for it to pass point A (-1, 5), substitute in x and y.

y = -7x + b

5 = -7(-1) +b

5 = 7 + b

b = -2

So the equation would be -7x - 2.

Your welcome!

Which visualization tool is more helpful for detecting outliers in data? Select one: a. scatter plot b. histogram c. Boxplot

Tpy6a [65]

Answer:

(A) Scatterplot

Step-by-step explanation:

The most helpful visualization to spot outliers would be a scatterplot.

When collecting data on a scatterplot, you can see how the results are similar and which areas have the most answers and such.

There can be multiply outliers on a scatterplot, and they stand out because while most answers will be clumped together, the outliers will not.

Valerie has a circular garden. The radius of the garden is 4 feet. She wants to buy edging to outline her circular garden.Which

ss7ja [257]

You'd need to find the distance AROUND the garden, which is also PERIMETER.

To find the perimeter of a circle, you use the following equation:
$2 \pi r$

$2 \pi (4)$ = $8 \pi$

$8 \pi$ = 25.13 ft

I don't know what your answer options are, but chose the option closest to 25.13 ft
