Answer:
$512.90 should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Normally distributed with mean $480 and standard deviation $20.
This means that [tex]\mu = 480, \sigma = 20[/tex]
How much should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05?
This is the 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95, so X when Z = 1.645.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.645 = \frac{X - 480}{20}[/tex]
[tex]X - 480 = 1.645*20[/tex]
[tex]X = 512.9[/tex]
$512.90 should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05

Answer:
{Segments, Geometric mean}
{PS and QS, RS}
{PS and PQ, PR}
{PQ and QS, QR}
Step-by-step explanation:
The three geometric mean relationships are derived from the similarity of the triangles the similarity proportions can be written 3 ways, each giving rise to one of the geometric mean relations.
short leg : long leg = SP/RS = RS/SQ ⇒ RS² = SP·SQ
short leg : hypotenuse = RP/PQ = PS/RP ⇒ RP² = PS·PQ
long leg : hypotenuse = RQ/QP = QS/RQ ⇒ RQ² = QS·QP
I find it easier to remember when I think of it as the segment from R is equal to the geometric mean of the two segments the other end is connected to.
__
segments PS and QS, gm RS
segments PS and PQ, gm PR
segments PQ and QS, gm QR
If you receive 25\% off an item costing $22.00, how much money do you save?
Answer:

Answer:
$5.50
Step-by-step explanation:
Hello! This is an easy one. If we are trying to find how much she is saving all we would need to do is multiply.
$22.00 * 25% = $5.50
If we are trying to find out the total with the discount all we would need to do is subtract.
22 - 5.5 = $16.50

Step-by-step explanation:
Use the coordinates of two points to determine the slope of the line through them.
Using (3,105) and (1,35): slope = (105-35)/(3-1) = 35
Point-slope equation for line of slope 35 passing through (1,35):
y-35 = 35(x-1)
y = 35x, which is equivalent to Brian's equation.
Which of the sets of equations represent the two lines graphed?
A)y=x+2 and y=x-4
B)y=x+2 and y=-x-4
C)y=-x+2 and y=x-4
D)y=x-2 and y=-x-4

The length, width, and height of the wooden box are 12.3 inches, 6.4 inches, and 7.5 inches respectively. The cost of painting the box is $0.25 per square inches. Find the total cost of painting the box.
Answer:
Step-by-step explanation:
Formula
The first thing you must do is find the surface area. The formula is right below this sentence.
Surface area = 2*L*w + 2*L*h + 2 * w * h Substitute givens into this formula
L = lengthw = widthh = heightThe choice of what to make the Length, width and height is arbitrary
Givens
L = 12.3 inchesw = 7.5 inchesh = 6.4 inchesSolution
Surface area = 2*12.3*7.5 + 2*12.3*6.4 + 2*7.5*6.4
Surface area = 184.5 + 157.44 + 96
Surface area = 437.94 in^2
Cost of Paint
The question is not really about Surface Area. The question is about the cost of paint given that 1 square inch costs 0.25 dollars.
Cost = Surface Area * 0.25
Cost = 109.485 dollars or
Cost = 109.49 rounded.

Jerome makes and sells his own energy drinks. He mixes powdered drink mix with water to create his own special blend.
Jerome usually uses 8 cups of water and 3 cups of drink mix. Tomorrow, there is a road race in town, however, and Jerome thinks he’ll be able to sell a lot more of his energy drinks than usual.
Jerome’s brother told him to add one cup of water for every one cup of drink mix he added to keep the ratio of water to drink mix the same and still increase the total amount of energy drink.
Jerome’s sister told him to multiply both the amount of water and the amount of drink mix by the same number to keep the ratio the same and still increase the total amount of energy drink.
Who is correct: Jerome’s brother or Jerome’s sister?
Answer:
Jerome's brother

A furniture salesman makes 3.5% commission. Her monthly sales are $18,545. Her annual salary is $18,995.80. What’s her monthly pay? Write just the value that represents your answer.
Using proportions, it is found that her monthly salary is of $1,528.9.
What is a proportion?A proportion is a fraction of total amount.
In this problem, her monthly sales are $18,545, with a commission of 3.5%, hence, in commission, the amount she makes is:
0.035 x 18545 = 649.075
Her annual salary is $18,995.80, of which 18995.80 - 649 = $18,346.8 she receives in 12 payments, hence:
18,346.8/12 = $1,528.9.
Her monthly salary is of $1,528.9.

180 - 55 - 55 = x, so

The easiest portion to check is the constant section in the interval [0, 6]. All of the function definitions agree on that, so that doesn't help choose the right answer.
__
Next easiest is the linear section at the right. It has a negative slope. Extension of the line to the y-axis shows it has a positive y-intercept. This eliminates choices A and D.
__
The horizontal asymptote of the exponential portion at the left is -5. Both of the remaining choices B and C agree on that. The exponential is increasing at an increasing rate, so its coefficient is positive. This eliminates choice B.
The appropriate description of the function on the graph is offered by choice C.
_____

Roger has to place cookies in plastic bags for a bake sale. He has 84 sugar cookies and 66 chocolate chip cookies. He wants to place the same number of cookies in each bag, wants to make sure that only one type of cookie goes into each bag, and wants to put the most cookies he can in each bag. How many cookies should be in each bag
Answer:
6 cookies
Step-by-step explanation:
Roger wants to place 84 sugar cookies and 66 chocolate chip cookies into plastic bags. Each bag must have the same number of cookies and only one type of cookie must be in each bag.
For the 84 sugar cookies:
number of cookies : 1 2 3 4 6 7 12 14 21 28 42 84
number of bags : 84 42 28 21 14 12 7 6 4 3 2 1
For the 66 chocolate cookies:
number of cookies : 1 2 3 6 11 22 33 66
number of bags : 66 33 22 11 6 3 2 1
The maximum common factor between 84 and 66 is 6.
Therefore 6 cookies should be placed in each bag. For sugar cookies, 6 cookies would be placed in each of the 14 bags while for the chocolate cookies, 6 cookies would be placed in each of the 11 bags.
