Answer:

I believe it is C because i heard of that one before

The measure of DE is 130 degrees if the measure of DEF is 65 in the circle option (A) is correct.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Circle is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have:

The measure of DEF = 65 degrees

C is the center.

Angle CED = 90 - 65 = 25 degrees

Angle DCE = 180 - 25 - 25

Measure of DE = 130 degrees

Thus, the measure of DE is 130 degrees if the measure of DEF is 65 option (A) is correct.

Answer:

13cm

Step-by-step explanation:

The pythagorean theorem states that, for right triangles, [tex]a^{2} +b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.

a = 12cm

b = 5cm

c = hypotenuse

[tex]12^{2} +5^{2} =c^{2}[/tex]

[tex]144+25=c^{2}[/tex]

[tex]\sqrt{169} =c[/tex]

13 = c

Answer:

13

Step-by-step explanation:

a^2+b^2=c^2

12^2+5^2=c^2

144+25=c^2

169

square root of 169=13

13=c

Answer:

Answer:

C. r = 28.50 ÷ 3

Step-by-step explanation:

You have to divide to see the rate

Given:

[tex]\to \text{time}= 3 \ hours\\\\\to \text{total eran}= \$28.50 \\\\[/tex]

To find:

earn per hour=?

Solution:

[tex]\to \text{time}= 3 \ hours\\\\\to \text{total eran}= \$28.50 \\\\[/tex]

calculate earn per hour:

[tex]= \frac{\text{total earn }}{ \text{time}}\\\\= \frac{28.50}{3}\\\\= \$ 9.5\\\\[/tex]

Answer:

The length of the rectangle is 28 inches.

Step-by-step explanation:

We have that the width (W) of a rectangle is half of the length (L) of the rectangle:

[tex] W = \frac{1}{2}L [/tex]  (1)

Also, the perimeter is 84 inches:

[tex] P = 2W + 2L = 84 in [/tex]   (2)

By entering equation (1) into equation (2) we have:

[tex]2(\frac{1}{2}L) + 2L = 84 in[/tex]

[tex] L = \frac{84}{3} = 28 in [/tex]

Therefore, the length of the rectangle is 28 inches.

Answer:

The mean of tree heights at Yard Works is 8 feet. The mean of tree heights at The Grow Station is 9 feet. The mean absolute deviations of the tree heights at both yards is 2.

Answer:

The heights, in feet, of the trees for sale at two nurseries are shown below.

Yard Works: 7, 9, 7, 12, 5

The Grow Station: 9, 11, 6, 12, 7

Which statements are true regarding the measures of center and variability of these data sets? Select three choices.

________________________________________________________

1  The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.

2  The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.

3  The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.

4  The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.

5  The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.

Step-by-step explanation:

Yard works has...

mean=8

median=7

mode=7

range=11

because in order it is 5 7 7 9 12

(5+7+7+9+12)/5=8

5 7( 7 )9 12 is the median

and seven occurs the most

and with this logic...

THE GROWSTATION has a

mean=9

median=9

mode=n/a

range=6

_______________________________________

    YEA) The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.

YEA) The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.

  YEA) The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.

The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.

The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.

Answer:

simplify the expression: 6x+5y

Step-by-step explanation:

Answer:

20, 68%, 0.687

Step-by-step explanation:

If 20 were to be a percentage, then it'll be less than 68% and 0.687. Since the 7 in 0.687 is greater than 5, you would round up when the question says so. 0.687 is greater than 68%; if you move the decimal 2 times to the right, then 0.687 would be 68.7%. Therefore the order from least to greatest is 20, 68%, 0.687.

Answer:

It's graph is symmetric to the origin. Cos (x) on the other hand is an even function cos (-x) = cos (x), and its graph is symmetric to the y-axis. Notice also that the graphs are exactly the same shape but horizontally shifted /2 units. They are related by: sin (x) = cos (x - /2) and cos (x) = sin (x + /2).
