Answer: A

Step-by-step explanation: once you line the numbers up in order from least the greatest, the two middle numbers will be 12. Add 12 + 12 and you get 24. Then divide it by 2 and get 12. That is your median. Your 1st quartile will be 10. Your second quartile will be 15. Your minimum number is 4 and your maximum number is 18.

Answer:

b ≈ 48.6°

Using the sine ratio in the right triangle

sin b = $\frac{opposite}{hypotenuse}$ = $\frac{9}{12}$ , then

b = $sin^{-1}$ ( $\frac{9}{12}$ ) ≈ 48.6° ( to 1 dec. place )

The graph shows a distribution of data. What is the standard deviation of the data? A)0.5 B)1.5 C)2.0 D)2.5

ruslelena [56]

Answer:

A)0.5

Step-by-step explanation:

We can see in the graph , that it is bell-shaped along x =2. A bell-shaped graph along one value is called symmetric graph and it represents a normal distribution.

Since, the give graph is symmetric around x=2, so the mean of the data is 2.

The point immediate left to the mean represents x-σ

so,

2 - σ = 1.5

So,

σ = 0.5

The sigma represents standard deviation.

Hence, Option A is correct ..

A company has 10 male and 11 female employees, and needs to nominate 2 men and 2 women for the company bowling team. How many di

Anvisha [2.4K]

2475 different teams can be formed.

Combination is the way in which items can be selected from a collection. If we have n total objects and r objects want to be selected, the number of combinations is:

$C(n,r)=\frac{n!}{(n-r)!(r)!}$

Since we need to nominate 2 men from a company of 10 males, the number of ways this can be done = $C(10,2)=\frac{10!}{(10-2)!(2)!} =45\ ways$

Also, we need to nominate 2 women from a company of 11 females, the number of ways this can be done = $C(10,2)=\frac{11!}{(11-2)!(2)!} =55\ ways$

Therefore the total number of different teams that can be formed = 45 ways * 55 ways = 2475 ways
