G. The salary of the employee that has been with the company the longest is the largest.

Answer:
i have the same problem :(
Step-by-step explanation:
have you gotten an answer yet?
Option J is not supported by the data
What is mean value ?The mean of a data set is actually the average value which is found by adding all numbers in the data set and then dividing by the number of values in the set.
How to find which options is not supported?The mean values of the salaries= $(50000+45000+32000+30000)/4
=$39250
Clearly we can see option H is correct.
Distance between first salary and the mean is $|50000 - 39250| =$10750Distance between second salary and the mean= $|45000-39250|=$5750Distance between third salary and the mean is $|32000-39250|=$7250Distance between fourth salary and the mean is $|30000-39250|=$9250So, average distance between each salary and mean salary is
$(10750+5750+7250+9250)/4 =$8250
Clearly, option F is correct also.
Option J is not correct because the variation of second salary with the mean is $5750 which is less than $6000.
So, option J is not supported.

The side lengths of a 30-60-90 triangle are in the ratio 1 : 3:2. What is
sin 30°?
Answers
Answer:
1/2
Step-by-step explanation:
other answer was wrong
The value of sin30 is [tex]\frac{1}{2}[/tex]
What is a 30-60-90 triangle?The 30-60-90 triangle is called a special right triangle as the angles of this triangle are in a unique ratio of 1:2:3.
According to the given sum:
In theory, we know,
For a 30-60-90 triangle, the sides opposite to 30° is x , side opposite to 60° is x*[tex]\sqrt3}[/tex] and the side opposite to 90° is 2x
Therefore,
If x = 1,
The sides are [tex]\sqrt{3},2,1[/tex] where,
perpendicular = [tex]\sqrt{3}[/tex]
Base = 1
Hypotenuse = 2
We know sinФ = [tex]\frac{perpendicular}{Hypotenuse}[/tex]
But in the case of sin30 , we have to take perpendicular as 1 and hypotenuse as 2, that is the angle has to be at base. If it was sin60, we would have taken perpendicular as [tex]\sqrt{3}[/tex] and hypotenuse as 2.
Therefore,
Sin30 = [tex]\frac{1}{2}[/tex]
Hence, we can conclude that the value of sin30 is [tex]\frac{1}{2}[/tex].

okay so angle O is connected to arc GU. to find angle O you musit find Arc GU
if Arc GO is 48 degrees and arc OU is 107 degrees, then you add those together.
107 +48=155
a circle has a total of 360 degrees
so 360-155= 205
205 is arc GU
205 divided by 2 will give you angle O
O is 102.5 degrees

The regular price of a video game is $59.,95. This week it is on sale for 15% off. What does the game cost this week (before taxes)
Answers
Answer: $50.96
Step-by-step explanation:
The regular price of a video game is $59.95 and we are told that this week it is on sale for 15% off.
The game cost this week before taxes will be:
= 59.95 - (15% × 59.95)
= 59.95 - (0.15 × 59.95)
= 59.95 - 8.9925
= $50.9575
= $50.96
The amount this week is $50.96

Answer:
sine of Z = 36.87 (36.86989765 to be exact)
Step-by-step explanation:
Remember SOH-CAH-TOA
Sine=OH=opposite/hypotenuse.
You want to find the angle of Z so, theta Z= 24/40 (O/H)
On your calculator, put inverse sine(sin ^-1) of 24/40.
So, sin-1 (24/40)=36.87 degrees.
