slava [35]

Answer:

7.55

Step-by-step explanation:

An arithmetic mean is the average value of all the data points.

In order to find the average value, you add all the data points then divide the resulting sum by the number of data points there are.

The sum of all data points:

3 + 9 + 10 + 5 + 8 + 5 + 9 + 11 + 10 + 3 + 10 =

The number of data points:

3, 9, 10, 5, 8, 5, 9, 11, 10, 3, 10

1,2,3,4,5,6,7,8,9,10, 11 = 11 data points

Average value/ Mean:

83 / 11 = 7.545454545454 = rounded to 7.55

Each week Josie's mother pays her an allowance to mow and water their front yard. Her mother pays her twice as much to mow the y

Sloan [31]

Answer: $30

Step-by-step explanation:

Let the amount paid to water the yard be represented by x.

Since her mother pays her twice as much to mow the yard as she does to water the yard. Therefore, the amount to mow the yard would be 2x.

Therefore,

2x + x = $45

3x = $45

x = $15

The amount to mow the front yard would be:

= $15 × 2

= $30

2. Find tan A for the right triangle below:

Andreyy89

Answer:

$tan A=\frac{8}{15}$

Step-by-step explanation:

According to the trigonometric ratios the tangent of an angle is the ratio of perpendicular to base, i.e.

$tan\theta=\frac{Perpendicular}{Base}$

In the provided triangle the perpendicular is 8 and base is 15.

Compute value of tan <em>A</em> as follows:

$tan\theta=\frac{Perpendicular}{Base}\\tanA=\frac{8}{15}\\$

Thus, the value of tan <em>A</em> is $\frac{8}{15}$ .
