Linda wants to determine the average salary for her employees for her Bakery business. Recorded below are the salaries for each

taurus [48]

The mean salary for Linda's employees is in thousands, is: 34,800.

Mean of a data set is the average of the data set.
To calculated the mean of a data set, use the formula: Mean = (∑fx)/∑f).

Thus:

∑fx = 974

∑f = 28

Therefore:

Mean = 974/28

Mean = 34.8

In thousands, the mean salary for Linda's employees is 34,800.

Two buses leave a station at the same time, traveling in opposite directions. The rate of the faster bus is 15 mph faster than t

ExtremeBDS [4]

A set of equation can be set up:
a=b+15
3(a+b)=345
where a is the faster and b is the slower bus.
substitute b+15 into the second equation, so 6b+45=345, and 6b=300, therefore b=50.
we can then figure out that a=65

Which is the closest to the value of x?

alina1380 [7]

<u>Answer:</u>

17.9

<u>Step-by-step explanation:</u>

Here we are given a right angled triangle with a known angle of 72°, length of the perpendicular to be 17 feet and we are to find the length of the hypotenuse x.

For that, we can use the formula for sin for which we need an angle and the lengths of base and hypotenuse.

$sin \alpha =\frac{perpendicular}{x}$

So putting in the given values to get:

$sin 72=\frac{17}{x}$

$x=\frac{17}{sin 72}$

$x=17.8$

Therefore, the length of six cars is the closest to 17.9.
