A company has offices in two different countries. The 125 employees at location A have a mean commute time of 40 minutes and a s

tandard deviation of 15 minutes. The 250 employees at location B have a mean and standard deviation of 35 and 10 minutes, respectively.
Every month, the company takes separate random samples of 20 employees from each location for a survey. Each time, they look at the difference in the mean commute time sampled from each location

Consider the formula: ...
Why is it not appropriate to use this formula for the standard deviation of ...
Choose

In the interval 0 to the power 0360 find x in which the sin is 0.6691. give your answer to the nearest degree
astraxan [27]

The angle for which the sine value is 0.6691 is found to be 42°.

What is the sine value?

A trigonometric function called sin x, where x is the angle under discussion stands for the sine of an angle. The sine function is the proportion between the perpendicular and hypotenuse of a right-angled triangle. In other words, the hypotenuse and its value change as the angle changes, and it is the ratio of the side opposite to the angle under discussion. In the study of physics, sound and light waves are represented by the sine function.

When the angle between a right-angled triangle's base and hypotenuse changes, the sine's value changes.

sin^{-1}(0.6691)=41.99°≈42°

How to solve 2.25 to the square root
Iteru [2.4K]
First find the answer without decimals
√225= 15

2.25 has two decimal places, so therefore the square root must contain 1 decimal place.
√2.25= 1.5

Final answer: 1.5
ps -1.5 is also correct but I'm not sure if that's what your teacher wants.

-<br> (<br> -<br> 7.4–1.1)–(2.1–8.1)
SashulF [63]

Answer:

0.3

Step-by-step explanation:

(7.4-1.1) - (2.1-8.1)

Lets start with (7.4-1.1)

Step 1:

(7.4-1.1) =6.3 (All you do is subtract 7.4-1.1 and it gives you 6.3)

Step 2: Lets do (2.1-8.1)

(2.1-8.1)= -6 (2.1 minus 8.1 gives you -6 because 2.1 is smaller than 8.1 so it will give you a negative)

Step 3: Subtract

6.3-6

So your answer would be 0.3

Hope that helped :)
