Answer:
(a) 259.5 days
(b) 284 days
Step-by-step explanation:
Let X represent the pregnancy length in days.
It is provided that [tex]X\sim N(270,9^{2})[/tex].
(a)
Let a represent the minimum pregnancy length that can be in the top 12% of pregnancy lengths.
Then,
P (X < a) = 0.12
⇒ P (Z < z) = 0.12
The corresponding z-score is, z = -1.17.
*Use a z-table.
Compute the value of x as follows:
[tex]z=\frac{x-\mu}{\sigma}\\\\-1.17=\frac{a-270}{9}\\\\z=270-(9\times 1.17)\\\\z=259.47\\\\z\approx 259.5[/tex]
Thus, the minimum pregnancy length that can be in the top 12% of pregnancy lengths is 259.5 days.
(b)
Let b be the maximum pregnancy length that can be in the bottom 6% of pregnancy lengths.
Then,
P (X > b) = 0.06
⇒ P (X < b) = 0.94
⇒ P (Z < z) = 0.94
The corresponding z-score is, z = 1.56.
*Use a z-table.
Compute the value of x as follows:
[tex]z=\frac{x-\mu}{\sigma}\\\\1.56=\frac{b-270}{9}\\\\z=270+(9\times 1.56)\\\\z=284.04\\\\z\approx 284[/tex]
Thus, the maximum pregnancy length that can be in the bottom 6% of pregnancy lengths is 284 days.

Answer:
x=16
Step-by-step explanation:
First, minus 80 from 180 because the sum of all the angles in a triangle is 180. Then use linear equations. 100=(4x-4)+(0.5x+32)
After that, you will get 100=4.5x+28
x=16

is (-2, 1) (-1, 3) (0, -2) (1, 3) ( -2, 1)a function?
Answer:
Yes this is a function.
Explanation:
Functions are those that DO NOT REPEAT x values, in this case, you will see that -2 repeats twice as an x value, but it is expressing the same point, so it will not be considered as going twice.

x-9=17 what’s the answer plz
Answer:
x=26
Step-by-step explanation:
x-9=17
1. add 9 to both sides:
x-9 +9 = 17 +9
x=26
2. check your answer by plugging the value of x back into the equation:
26-9=17
17=17, so the answer is correct

so how do i so how do I solve to get this answer
Step-by-step explanation:
First, You would solve what you can which would be the equation on the left Which will get you 4096. After that its just solving for P
4096=(4^p)^2
64=4^p (you would take the square root of 4096 to get 64)
Then, Since 64 is a perfect Cube root of 4, P will equal 3

Given
3m + 8 = 15 ( subtract 8 from both sides )
3m = 7 ( divide both sides by 3 )
m = [tex]\frac{7}{3}[/tex]
Vannorman Corporation processes sugar beets in batches. A batch of sugar beets costs $78 to buy from farmers and $18 to crush in the company's plant. Two intermediate products, beet fiber and beet juice, emerge from the crushing process. The beet fiber can be sold as is for $25 or processed further for $16 to make the end product industrial fiber that is sold for $57. The beet juice can be sold as is for $39 or processed further for $22 to make the end product refined sugar that is sold for $84. How much profit (loss) does the company make by processing one batch of sugar beets into the end products industrial fiber and refined sugar?
Answer:
Results are below.
Step-by-step explanation:
We will take into account the differential costs only. Therefore, the costs of sugar beets and to crush them are irrelevant to decision making.
Beet fiber:
Sold as is= $25
Continue processing= 57 - 16= $41
It is more convenient to process further the beet fiber.
Beet juice:
Sold as is= $39
Continue processing= 84 - 22= $62
It is more convenient to process further the beet juice.
Find the distance between the parallel lines m and n whose equations are
(y = x + 4) and (y = x - 6.)
Answer:Find the distance between the parallel lines m and n whose equations are y = x + 4 and y = x - 6, respectively.
There are several ways to do this...here's one
Let (0, 4) be a point on the first line
Then.......a line with a negative reciprocal slope going through this point will have the equation :
y = -x + 4........so......we can find the intersection of this line with y = x - 6....set both equations equal
-x + 4 = x - 6 add x, 6 to both sides
10 = 2x divide both sides by 2
5 = x
So...using -x + 4, the y value at intersection = -1.......
So...we just need to find the distance from (0,4) to ( 5, -1) =
√[ (5)^2 + (4 + 1)^2 ] = 5√2 ≈ 7.07 units
Here's a pic....AB is the distance with A = (0,4) and B = (5, -1)

If m DGE=52 and FGE is a right angle, what is the measure of DGF
Answer:
DGF=38
Step-by-step explanation:
FGE is the total angle that adds up to 90 degree. We know that it is bisected into 2 separate angles where we know DGE is 52 but not DGF.
We use the following information above to make the equation x + 52 = 90 (x represent the unknown degree)
Then you just solve normally where you subtract 53 from 90 and get the solution of x=38.

Answer:
Very small
Step-by-step explanation:
Answer:
very small
Step-by-step explanation:
Scientific notation is used to shorten numbers that are either very large or small, so negative and positive aren't really relevant answers.
Now you have to determine if the number 9.3 x 10^-8 is very large or small.
When dealing with scientific notation, a negative exponent means the number was originally a decimal and a positive exponent means the number was very large. The exponent is negative 8 so it is very small.
0.023 = 2.3 x 10^-2
2300. = 2.3 x 10^3
Nicole accepted a new job at a company with a contract guaranteeing annual raises. In the first year, Nicole's salary will be $100000 and after working for the company for 5 years, she will have a salary of $110000. Write an equation for S. S, in terms of
n, representing Nicole's salary after working
n years for the company
Answer:
S = 100,000 + 2,000n
Step-by-step explanation:
The salary went up $10,000 in 5 years, so the average raise seems to be $2000 per year. Of course, the initial salary is 100,000. Then ...
S = 100,000 + 2,000n
The expression shown can be used to calculate the amount of money in dollars a grocery store customer should receive in change when paying with $50. 50 − ( 14 + 12 + 2 ( 5 ) + 2 ( 2 ) + 3 ) What amount of change in dollars should the customer receive?
Answer:
The change received by the customer is $7.
Step-by-step explanation:
First, write the given expression for the change when paying with $50.
[tex]50 - ( 14 + 12 + 2 ( 5 ) + 2 ( 2 ) + 3 )[/tex]
Evaluate the parentheses:
[tex]50-(26+10+4+3)[/tex]
Now add the numbers inside the parentheses.
[tex]50-43[/tex]
Subtract the numbers.
[tex]7[/tex]
Hence, the change received by the customer is $7.
