Answer:

The Interquartile range is 10.

Step-by-step explanation:

First, we will need to find the mean, the mean of this sequence is 16, you will now need to find quartile 1 and quartile 3. Quartile 1 is 13, and quartile 3 is 23. Lastly, subtract Quartile 3 and Quartile 1 will be the answer.

So, 23-13=10

The Answer will be 10, the interquartile range is 10.

Hope this helps!

Please help ! ;v; A coordinate plane is shown. A line passes through the point (-4,1) and through the y-axis at 4. What is the y

nignag [31]

Answer:

(0, 4)

Step-by-step explanation:

The y-intercept is where the graph crosses the y-axis when x = 0. Since you are given the graph, you can see that when x = 0, the graph crosses y = 4, so our y-int is (0, 4).

what is the distance between (0, -2) and (9, 10) ? please show your work so i can understand thank you

Setler [38]

Given:

The two points are (0, -2) and (9, 10).

To find:

The distance between the given points.

Solution:

Distance between the two points is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Using the above distance formula, the distance between given points is

$d=\sqrt{(9-0)^2+(10-(-2))^2}$

$d=\sqrt{(9)^2+(10+2)^2}$

$d=\sqrt{81+(12)^2}$

On further simplification, we get

$d=\sqrt{81+144}$

$d=\sqrt{225}$

$d=15$

Therefore, the distance between the given points (0,-2) and (9,10) is 15 units.

A recipe requires 7/8 stick of butter for each 1 1/4 cups of flour. Find the unit rate of sticks of butter to cups of flour.

Sholpan [36]

Answer:

Let R = unit rate

R = (7/8) ÷ 1_1/4

R = (7/8) ÷ (5/4)

R = (7/8) • (4/5)

R = (7/2) • (1/5)

R = 7/10

She needs to purchase a cover to protect the hot tub of an area of 38.5 square feet.

<h3>What is a circle?</h3>

It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

Claire has a hot tub with a diameter of 7 feet. She wants to purchase a cover to protect the hot tub.

The area of the circle is given by

$\rm Area = \dfrac{\pi}{4}d^2$

We have d = 7 ft, then the area of the circle will be

$\rm Area = \dfrac{3.14}{4}*7^2\\\\Area = 38.5 \ ft^2$

More about the circle link is given below.

Answer:

-1458

Step-by-step explanation:

Let's find the rule of the sequence. It seems that each term is -3 times the previous term.

Let's continue the sequence.

486, -1458

-1458 is the 7th term
