Find the slope of the line that passes through the ordered pairs (-2,8) and (-9,19)
Ilia_Sergeevich [38]

Answer:

slope: -11/7

Step-by-step explanation:

Slope is equal to the change in yy over the change in xx, or rise over run.

m=change in ychange in xm=change in ychange in x

The change in xx is equal to the difference in x-coordinates (also called run), and the change in yy is equal to the difference in y-coordinates (also called rise).

m=y2−y1x2−x1m=y2-y1x2-x1

Substitute in the values of xx and yy into the equation to find the slope.

m=19−(8)−9−(−2)m=19-(8)-9-(-2)

Simplify.

m=−11/7

Draw a histogram for the intervals 17-19, 20-22, 23-25, and 26-28 using the following data: 19, 19, 27, 20, 27, 26, 25, 26, 18,
snow_lady [41]

Intervals are given to us

19, 19, 27, 20, 27, 26, 25, 26, 18, 27, 20, 24, 19, 21, 27, 23, 21, 17, 22, 22

From the given data we need to create a frequency table

From 17 - 19 there are 5 numbers. they are 19,19,19, 18, 17

From 20 -22 there are 6 numbers . they are 20, 20, 21, 21, 22, 22

From 23 - 25 there are 3 numbers. they are 23, 24, 25

From 26 to 28 there are 6 numbers . they are 27, 27, 26, 26, 27, 27

Histogram is attached below

What’s the answer ???<br><br> (ONLY ANSWER IF YOU KNOW)
just olya [345]
First, it says to simplify the expression, so you should try that first.

Simplified Expressions:
8y^15 and 36y^7

Then compare on which simplified expression has the greater exponent
8y^15 and 36y^7
8y^15 has the greater exponent

8y^15 = (y^9)(2y^2)^3 (Or the first expression)

The exponents of expression #1 are greater than the exponents of expression #2

How do I find the area of the shaded blue region?
kogti [31]

That's a 240 degree sector of a 9 inch radius circle.  The whole circle has area πr² and we want 240/360 of it.

A = (240/360) π (9²) = 54 π

Answer: 54 π square inches

That's the exact answer.  An approximation is

169.646 square inches
