Complete Question
Assume the readings on thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.0°C. Find the probability that a randomly selected thermometer reads between 0.50°C and 1.50°C and draw a sketch of the region.
Answer:
0.24173
Step-by-step explanation:
We would solve this question using Z score formula.
z = (x-μ)/σ
where:
x is the raw score
μ is the population mean = 0°C
σ is the population standard deviation = 1°C
For x = 0.5°C
z = (0.5 - 0)/1
z = 0.5
Probability value from Z-Table:
P(x = 0.5) = 0.69146
For x = 1.5°C
z = (1.5 - 0)/1
z = 1.5
Probability value from Z-Table:
P(x = 1.5) = 0.93319
The probability of that a randomly selected thermometer reads between 0.50°C and 1.50°C is calculated as:
P(0.5 < Z < 1.5) = P(x = 1.5) - P(x = 0.5)
= 0.93319 - 0.69146
= 0.24173

Which of the following is a divisor of 12! · 6! + 12! + 6! + 1?
A. 21
B. 77
C. 91
D. 115
E. 143
Hint : Use Wilson's Theorem[tex].[/tex]
Answer:
C. 91Step-by-step explanation:
Rewriting the given as factors:
12! · 6! + 12! + 6! + 1 =12!(6! + 1) + (6! + 1) =(12! + 1)(6! + 1) =((13 - 1)! + 1)((7 - 1)! + 1)As per Wilson's theorem, if n is prime number, (n - 1)! + 1 is divisible by n
As per above, 13 and 7 are both prime numbers, so the expression is divisible by both 7 and 13:
7*13 = 91So correct choice is C

Sam is a movie reviewer. He attended a premiere and wants to know what the audience thought of the movie. There were 500 guests at the premiere. Sam asked 10 guests to rate the movie on a scale of 1 to 5. Here are the ratings he collected: 2, 3, 1, 3, 2, 5, 4, 1, 2, 2 Can the data given be used to calculate a point estimate of the rating of all the guests who attended the premiere? If so, calculate it. Round non-integers to the nearest tenth. If no assumptions can be made, type 0 in the box. The approximate guest rating for the movie by all the guests is .
Answer:
The approximate guest rating for the movie by all the guests is 0.
What is the equation of the line that passes through the point (2, -2) and has a
slope of -1/2?
Answer:
Step-by-step explanation:
use the point-slope formula [y-y1 =m(x-x1) ] with the given info
for the point P=(x1,y1) =(2,-2) and the slople m = -1/2
plug those into the formula
y-(-2)= -1/2(x-2)
y+2= -1/2x + 1
y= -1/2x+1 - 2
y = -1/2x - 1
:) got it?
these are hard untill you get the idea of the two formulas
point-slope: y-y1 = m(x-x1) and
slope-intercept: y= mx+b
memorizing those will help a lot

The formula for calculating your credit utilization ratio is pretty straightforward. To figure it out for an individual card, divide your credit card balance by your available credit line.
What you you do is divide the credit card ratio for each one.
For the first card: $2,397 (total on card) divided by 16,000, (the limit) is 0.149, we round that to 0.15. (15%)
For the second card: $1,218 (total on card) divided by 5,500 (the limit) which is 0.221. We round that to 0.22. (22%)

How can I tell that a graph is a function or not?
Answer:
You can use the vertical line test, which means anywhere you put it on the graph it should only pass through the line once.
Step-by-step explanation:
This insures that the graph does not have two of the same x values. However if it has two points that have the same x values that means it will not be a function.

Sand for use on icy roads is stored in a conical pile 14.2 m high and with a base diameter of 34.4 m calculate the volume of the pile if one sander can take 6.9 m of sand, how many sanders can be filled from the pile
Answer:
1. The volume of the pile is 4,399.7719 m^3
2. The number of sanders to be filled from a pile is 638
Step-by-step explanation:
Here, we firstly would calculate the volume of the pile
Mathematically, that will be;
V = 1/3 * pi * r^2 * h
from the question, h = 14.2
Mathematically, r = d/2
r = 34.4/2 = 17.2 m
So the volume will be:
V = 1/3 * 3.142 * 17.2^2 * 14.2
V = 4,399.7719 m^3
To find the number of sanders to be filled,
we simply divide the volume obtained by the volume a sander can take
That will be;
4,399.7719/6.9
= 637.6 which is 638

~I hope I helped you :)~
I hate math
First thing's first, PEMDAS. There's nothing to solve in the parenthesis, and there are no exponents, so use multiplication next. 6 • (x-2) and -8 • (x-3)
Your equation after should be
5x + 6x - 12 - 8x + 24
Next would be addition, don't forget it's always left to right.
11x - 12 - 8x + 24
Subtract twelve from the total (or in this case just from 24, and then add the remaining values (that are possible).
11x - 8x + 12
Next, subtract the two remaining x values.
3x + 12
And there you have it. Easy peasy.
If the case is trying to find x, just solve it like this.
3x = -12
x = 4

What is 24 − 6 × 3 + 52 − (16 ÷ 2)?
Answer:
23
Step-by-step explanation:
When answering expressions like these we should always go by the order of operation. That order tells us to do parentheses, exponents, multiplication/division, then addition/subtraction. So as it said we will do whatever is inside the parentheses which is 16 ÷ 2.
24 − 6 × 3 + 5^2 − (16 ÷ 2)
24 − 6 × 3 + 5^2 − 8
Next is the exponent.
24 − 6 × 3 + 5^2 − 8
24 − 6 × 3 + 25 − 8
Now we will do multiplication/division.
24 − 6 × 3 + 25 − 8
24 − 18 + 25 − 8
Lastly we'll do addition/subtraction.
24 − 18 + 25 − 8
6 + 25 - 8
31 - 8
23
And that's it we got it!
24 - 6 x 3 + 52 - (16/2)= 50 !
Step-by-step explanation:
Hope this helps
