Can someone tell me the awnsers for 15

Answer:

Step-by-step explanation:

1. the company C used 10 drivers

2.      6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10  

(6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)

4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4  = 16/10 = 1 6/10

3. The groups that had the most deliveries where group A and B

4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4

By reading the dot plot,

Number of drivers used by company C in its sample = 10

Mean absolute deviation for company C's data = 2

Company B has the greatest mean number of deliveries.

The mean deliveries of company B is 4 times MAD of company A.

Dot plot is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis.

Number of units used in the sample of a dot plot can be calculated by simple counting.

The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.

We are given the sum of each point from the mean. It is 20. Mean absolute deviation can be calculated by dividing this sum by number of observations.

Mean absolute deviation of company C  = 20/10 = 2.

Mean A = 6

Mean B = 14

Mean B - Mean A = 8 = 4 * 2 = 4 times MAD (since MAD =2 for both companies).

Step-by-step explanation:

Answer:

(a) 7 + 4 = 11

(b) 1 + 3 + 5 = 9

(c) (7 x 2) + 1 = 15

(d) (7 x 2) - 1 = 13

(e) 13 - 9 = 4

Step-by-step explanation:

(a) 5 + 4 = 9

(b) 7 + 1 + 11 = 19

(c) 25 = 12 + 12 + 1

(d) 7 = 4 + 4 - 1

Answer:

29

Step-by-step explanation:

20^2 times 3.14= 1256

21^2 times 3.14= 1384.74

the sum of those two is 2640.74

the square root of that is 29

The radius of the circle is 29 cm.

We have the circle whose area is equal to the sum of the areas of two circles whose radii are 20cm & 21cm.

We have to find the radius of the circle.

Let the radius of the circle be x.

We know that the area of the circle is [tex]\pi r^{2}[/tex]. Then -

[tex]\pi x^{2} =\pi r^{2} +\pi R^{2} \\x=\sqrt{r^{2} + R^{2}} \\[/tex]

Now, in the question given to us -

r = 20cm  and R = 21cm  and 'x' denotes the radius of the circle we have to find.

Substituting the values in the above formula, we get -

x = [tex]\sqrt{400+441}[/tex]

x =29 cm

Hence, the radius of the circle is 29 cm.

Answer:

Then you have infinite solutions

Step-by-step explanation:

if no solution, you would get sum lyke 4 = 5

if infinite soltution you would get sum lyke 3 = 3

if you have one solution, expect to get sum lyke x = 5

Answer:

x = [tex]\frac{-212}{3}[/tex]

y = 24

Step-by-step explanation:

-3x - 8y = 20  .... (1)

-5x + y = 19   .... (2)

What we can do is take the (2) equation

-5x + y = 19

and solve for y by adding 5x to both sides

y = 24

now that we have y we substitute it in for y in equation (1)

-3x - 8(24) = 20

-3x - 192 = 20

we want to solve for x so we need to get its self.

add 192 to both sides

-3x = 212

now we divide both sides by -3. It's going to be a fraction.

x = [tex]\frac{-212}{3}[/tex]

Answer:

x=-4

y=-1

Step-by-step explanation:

-3x-8y=20

-5x+y=19

rewrite for y:

y=19+5x

substitute y

-3x-8(19+5x)=20

-3x-152-40x=20

-3x-152-40x+152=20+152

-43x=172

-43x/-43=172/-43

x=-4

substitute x

-5(-4)+y=19

20+y=19

y=-1

check:

-3(-4)-8(-1)=20

12+8=20

-5(-4)+-1=19

20-1=19

Answer:

5.83 blocks away from his home

Step-by-step explanation:

If he travels 5 blocks south and 3 blocks west, the distance from his house considered along with the distances travelled gives a right angled triangle whose opposite side and adjacent sides are the distances travelled north and west.

The distance from his house after moving 3 blocks west is the hypotenuse side. As such, the distance may be computed using Pythagoras' theorem. Let the distance from his house be G

G^2 = 5^2 + 3^2

G^2 = 25 + 9

= 34

G = √34

=5.83
