The Box-and-Whisker Graph Shows The Heights, In Inches, Of Children Between Ages Of 7 And 14. Between

Answers

Answer 1

Answer:

A. Between 52 and 61

Step-by-step explanation:

In this box and whisker plot Q1 represents the first quartile or the bottom 25% of all the data(25th percentile)

Q2 represents the second quartile and represents the lower  50% of all the data 50th percentile). The middle line represents the median of the data set.

Therefore the lower 50% of the data is found between 52 (lower limit) and 62(50th percentile)

PLEASE HELP I will pick brainiest

Answers

Answer:

See below.

Step-by-step explanation:

1.) 7 +7x

7(x + 1/7) = 7x + 1

No

2.) 2.5(3+x) = 7.5 + 2.5x

2.5x + 7.5

Yes

3.) 3m-6+m^2-5m+1 = m² - 2m - 5

4.) 7x+4(2x-6) = 7x + 8x - 24 = 15x - 24

5.) b^2+3+2b^2+4-7 = 3b²

6.) 3(p+5)-8+11p = 3p + 15 - 8 + 11p = 14p + 7

A′(0, 0), B′(−2, −5), C′(−5, 5), D′(−3, 0)
A′(0, 0), B′(−5, −2), C′(5, −5), D′(3, 0)
A′(0, 0), B′(−5, −2), C′(−5, −5), D′(0, 3)

Answers

Answer:

A

Step-by-step explanation:

Rotating CCW 90 ° will cause this change in coordinates

Answer: Is would be A

Step-by-step explanation: Because since it is 90 degrees counterclockwise you would do the 270 formula since it is counterclockwise and the formula for 270 degrees is basically swapped the x and the y and add a negative to the original y and if it's already a negative it becomes a pthe polygon, so the answer is A (0, 0), B(-2, 5), C(5, 5), D(3, 0) the first one

4(-5) + 5 = -20 + 5 = -15

explain how you find the Area of a Circle

Answers

Answer:

A=πr2

Step-by-step explanation:

That is the formula to solve areal for a circle.

The Area of a circle is ( = π ² )


Area of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula ( = π ² ) , (Pi r-squared) where is the radius of the circle. The unit of area is the square unit, such as m2, cm2, etc.

is the region covered or enclosed within its boundary. It is measured in square units. Any geometrical shape has its own area. This area is the region that occupies the shape in a two-dimensional plane. So the area covered by one complete cycle of the radius of the circle on a two-dimensional plane is the area of that circle.

As we know, the is equal to of its radius, i.e. π . To find the area of circle we have to know the of the circle.
For example, if the radius of circle is 7cm, then its area will be:
Area of circle with 7 cm radius = πr2 = π(7)2 = 22/7 x 7 x 7 = 22 x 7 = 154 sq.cm.

First you solve the first part (-5-4) and get -9.

Then you solve the second half (1+-3) and get -2

You then have the equation -9--2

But because you're subtracting a negative, it turns into a positive.

So now our equation is -9+2

And you get -7.
