Answer 1
The answer is x=15
First figure out the angle: the angle is supplementary which equals to a total of 180 degrees. So in order to find x we must add 7x+60 and 15 and equal it to 180 degrees.
7x+60+15=180

Then you will add like terms on both sides which is 60 and 15 which gets you 75.
7x+75=180
Then you need to get x alone so you will subtract 75 on both sides.
7x+75= 180
-75 -75
———————
7x=105
Then you divide both sides by 7 so you can get x by it self.
7x=105
—-=——
7 7
This will give you x = 15.
Now that you have what x is you need to find the missing angle. You will do this by plugging in x=15 into 7x+60
7(15)+60
105+60= 165
To check you work you can add up both angles to see if you will get 180 as you total if u do it’s correct.
165+15=180

The amount of snowfall falling in a certain mountain range is normally distributed with a mean of 70 inches, and a standard deviation of 10 inches. What is the probability that the mean annual snowfall during 64 randomly picked years will exceed 72.8 inches

Answers

Answer:

The probability that the mean annual snowfall during 64 randomly picked years will exceed 72.8 inches is 0.3897

Step-by-step explanation:

Mean =[tex]\mu = 70 inches[/tex]

Standard deviation =[tex]\sigma = 10 inches[/tex]

We are supposed to find the probability that the mean annual snowfall during 64 randomly picked years will exceed 72.8 inches

We will use z-score formula :

[tex]Z = \frac{x-\mu}{\sigma}\\Z=\frac{72.8-70}{10}\\Z=0.28[/tex]

We will use z table

[tex]P(X \geq 72.8)=1-P(X\leq 72.8)=1-0.6103=0.3897[/tex]

Hence  the probability that the mean annual snowfall during 64 randomly picked years will exceed 72.8 inches is 0.3897

12 women and 18 men are on the faculty in the Computer Science department at Whatsamatta U. a. How many ways are there to select a committee of 6 members of the department if at least two women must be on the committee

Answers

Answer:

183,600 ways

Step-by-step explanation:

TOPIC : PERMUTATION & COMBINATION

Question: In how many ways can a committee of 6 members - with at least 2 women - be selected?

In other words, how many ways are there, to select a committee of 6 members including at least 2 women?

* Permutation deals with the orderly arrangement of items while Combination deals with the manner of selection of items from a group, without regard to order. In other words, this question has to do with Combination.

There are 12 women and 18 men and you're to select 2 women and 4 men.

The combination for men and women will be found separately and then multiplied together.

WOMEN: 2 OUT OF 12

12! ÷ [2! × (12 - 2)!]  =  12! ÷ [2! 10!]

= 12×11×10×9×8×7×6×5×4×3×2×1   = 479,001,600  =  66

  2×1   ×10×9×8×7×6×5×4×3×2×1       7,257,600

MEN: 4 OUT OF 18

18! ÷ [4! (18 - 4)!]  =  18! ÷ [4! 14!]

= 18×17×16×15×14×13×12×11×10×9×8×7×6×5×4×3×2×1  = 3,060

  4×3×2×1   ×14×13×12×11×10×9×8×7×6×5×4×3×2×1

ANSWER:

₁₂C₂  ×  ₁₈C₄  = 66 × 3060  = 183,600
