Answer:

43 is the mean

Step-by-step explanation:

In order to calculate the mean, you just have to add up all of the values in the data values, and then you just have to divide it by the number of values in the set, in this specific set you have 5, and you have to divide the total of the sum by 5.

22+37+49+15+92= 215

So then you just divide 215 between 5:

215/5= 43

So the mean of the data values is 43.

We have that

[<span>22,37,49,15,92]

step 1
</span>First add all the variables up.
[22+37+49+15+92] = 215
step 2
Then divide the answer by how many variables there are.
215 divide by 5 = 43

the answer is
the mean is 43

Two planes, A and B, start from the same place and move in different directions, making an angle of 50º between them. The speed

cluponka [151]

Answer: The distance between them is 230.65 miles.

Step-by-step explanation:

Since we have given that

Speed of plane A (b) = 200 miles per hour

Speed of plane B (c) = 300 miles per hour

Angle between them = 50°

So,

We will use the "Cosine formula", we get

$a^2=b^2+c^2-2bc\cos A\\\\a^2=200^2+300^2-2\times 200\times 300\cos 50\textdegree\\\\a^2=40000+90000-120000\cos 50\textdegree\\\\a^2=130000-120000\times 0.64\\\\a^2=130000-76800\\\\a^2=53200\\\\a=\sqrt{53200}\\\\a=230.65\ miles\ per\ hour$
