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
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

Answer:
55
Step-by-step explanation:
if oak trail is 125 then pine trail is also 125 and we know that a straight line is 180 so 180-125=55
Answer:
55 degrees
Step-by-step explanation:
180 degrees - 125 degrees
The line with 125 is a flat line which is 180 degrees. The oak trail and pine trail are parallel which means they both are 180 degrees. So 180-125 is x.

A boat leaves the marina and sails 13 miles northeast, then 12 miles east. In what direction must the boat sail to head directly back to the marina?
a. 66.55° W of S
b. 23.45° W of S
c. 45.00° E of N
d. 66.55° E of N
Answer: c
Step-by-step explanation: this answer is Unknown
The direction of the boat sail to head directly back to the marina which leaves the marina and sails 13 miles northeast, then 12 miles east is 23.45° W of S.
What is the law of cosine?When the three sides of a triangle is known, then to find any angle, the law of cosine is used.
It can be given as,
[tex]c^2=a^2+b^2-2ab\cos C\\a^2=c^2+b^2-2ab\cos A\\b^2=a^2+c^2-2ab\cos B[/tex]
Here, a,b and c are the sides of the triangle and A,B and C are the angles of the triangle.
A boat leaves the marina and sails 13 miles northeast, then 12 miles east. The image of the problem is attached below.
Thus, the value of the third side is,
[tex]c=\sqrt{12^2+13^2-(2\times12\times13\times \cos 135)}\\c=23.01[/tex]
The measure of the angle x is,
[tex]\angle x=\cos^{-1}\dfrac{23.1^2+13^2-12^2}{2\times23.1\times13}\\\angle x=23^o26'57"\\\angle x=23.449^o[/tex]
Thus, the direction of the boat sail to head directly back to the marina which leaves the marina and sails 13 miles northeast, then 12 miles east is 23.45° W of S.

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
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

[tex]\Huge\boxed{x=6}[/tex]
Step-by-step explanation:
In order to solve this equation, our goal is to "reverse" the equation until we have x isolated on one side.
[tex]6x+4x-5=55[/tex]
We can first combine the x terms.
[tex]10x-5=55[/tex] Add 5 to both sides: [tex]10x=60[/tex] Divide both sides by 10: [tex]x=6[/tex]So x = 6.
Hope this helped!
