Answer:
(52.50x + 500) is greater or less than (60.50x + 300)
Step-by-step explanation:
Hope I answered your question!
The required inequality is given by 52.50x + 500 ≥ 60.50x + 300.
Given that,
Lola needs to rent a borrow for a formal event Heroes charges $52.50 per hour with a one-time rental fee of $500 by Ballroom T charges $60.50 per hour and a one-time fee of $300.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
Let the number of hours be x,
According to the question,
so,
52.50x + 500 ≥ 60.50x + 300
Thus, the required inequality is given by 52.50x + 500 ≤ 60.50x + 300.

Determine which expressions could be used to help find each component of the ice cream cone. ( answer choices are in picture question 2 )
Answer:
1). a
2). b
3). c
4). d
Step-by-step explanation:
From the picture of a cone attached,
Radius of the circular top = r
Height of the cone = h
Slant height of the cone 'l' = 6
Area of the circular top of the cone with radius 'r' = πr²
Amount of space inside the cone = Volume of the cone = [tex]\frac{1}{2}\pi r^{2} h[/tex]
The amount of wrapper needed to cover the side of the ice cream cone, not including the circular top of the cone = πrl = πr(6 in.)
The vertical height 'h' of the cone when the cone is standing upright = [tex]\sqrt{6^2-r^2}[/tex]
[By Pythagoras theorem, l² = h² + r² ⇒ h = [tex]\sqrt{l^2-r^2}[/tex]]

The inventory policy of a retail company is to hold only the highest sales volume items in its distribution center and to ship the remaining lower sales volume items direct from the respective manufacturers to its stores. This policy is intended to reduce transportation costs. Total annual sales of the company are $1 billion. It is known that half of this amount is accounted for by only 15% of the items. In addition, it is assumed that equation (8.1) in the text can be used to model the Pareto cumulative distribution. (a) If the company wants to stock the top selling 35% of the items in the distribution center, what is the expected value of these items in terms of annual sales? (b) On the other hand, if the company wants to stock only those items accounting for the top 75% of annual sales, what proportion of the items corresponds to this sales volume?
Answer:
a. 75.3% is the expected percentage and this value corresponds to 753 million dollars
b. 34.62% of items corresponds to 75% of this sales volume
Step-by-step explanation:
a. A =x(1-y)/(y-x)
X = 0.15, y = 0.50
A = 0.15(1-0.50)/(0.50-0.15)
= 0.15(0.5)/0.35
A = 0.2143
we have
x = 0.35
y = 0.35(1+0.2143)/(0.2143+0.35)
y = 0.425005/0.5643
y = 0.7531
y = 75.3%
75.3% is the expected percentage and this value corresponds to 753 million dollars
b. y = 0.75
find x
y = x(1+A)/(A+x)
x = yA/(1+A-y)
x = 0.75(0.2143)/1+0.2143-0.75)
x = 0.160725/0.4643
x = 0.3462
34.62% of items corresponds to 75% of this sales volume

An engineering firm offers testing for electrical products. Currently they are testing a type of compact portable music player. They randomly select a number of the music player and conduct a series of tests and compute an overall score for each unit based upon the results of the testing routine. They determine that the test scores are normally distributed with a mean of 374 and a variance of 1,090. A unit is deemed faulty if it scores below 320. Find the probability of a random unit being faulty. Give your answer as a decimal to 2 decimal places.
Answer:
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = 0.0505
Step-by-step explanation:
Explanation:-
Given mean of the Population 'μ' = 374
Variance of the Population σ² = 1090
Standard deviation of the Population 'σ ' = √1090 = 33.01
Given 'X' be a random variable in normal distribution
[tex]Z = \frac{x -mean}{S.D} = \frac{320-374}{33.01} = -1.636[/tex]
Z = - 1.64
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = P( Z < - 1.64 )
= 1- p(Z > 1.64)
= 1 - ( 0.5 + A(1.64)
= 0.5 - 0.4495
= 0.0505
The probability of a random unit is deemed faulty if it scores below 320.
P( X < 320 ) = 0.0505

Ramon is making book shelves. He bought a board that is 4/5 meter long. He needs 5 shelves. If he cuts 5 equal-sized pieces from the board, how long is each piece?
Answer:
Each board is (4/25) meters long = 0.16 meters long
Step-by-step explanation:
The board is 4/5 meters long, and he needs to cut 5 equal pieces, so we need to divide 4/5 of a meter in 5 parts.
This mathematically becomes: 4/5 divided by 5 which by the definition of division of rational numbers, is the same as :
4/5 times the reciprocal of 5 = (4/5) * (1/5) = (4/25) = 0.16 meters each board

Step-by-step explanation:
the length of LO if M is between L and O, LM = 7x – 9, MO = 14 inches, and LO = 10x – 7.
LM+MO=LO
7x-9+14=10x-7
7x+5=10x-7
7x-10x+5-5=10x-10x-7-5
-3x=-12
-3x/-3=-12/-3
x=4
10*4-7
=40-7
=33 in.
The length of LO is 33 inches.
It is given that LM = 7x - 9.
MO = 14
LO = 10x - 7
What is an equation?Equation is the combination of variables, constant and mathematical symbols.
M is between L and O
LM + MO = LO
7x - 9 + 14 = 10x - 7
7x - 10x = -7 + 9 - 14
- 3x = - 21 + 9
- 3x = - 12
x = 12/3
x = 4
So , putting the value of x in LO = 10x - 7
LO = 10 (4) -7
LO = 40 -7
LO = 33 inches
The length of LO is 33 inches.

Which graph shows a negative rate of change for the interval 0 to 2 on the x-axis?
Answer:
The last graph
Step-by-step explanation:
Graphs 3 and 4 have negative rates of change.
Options C and D are the correct answer.
We have,
The rate of change for the interval 0 to 2 for each graph can be calculated as:
= (b - a) / (2 - 0)
Where (0, a) and (2, b) are the coordinates on each line.
Now,
Graph 1:
Rate of change.
= (0 - (-3) / (2 - 0)

Graph 3:
Rate of change.
= (-4 - (-3) / (2 - 0)
= (-4 + 3) / 2
= -1/2
Graph 4:
Rate of change.
= (0.5 - 2) / (2 - 0)

"a number times negative seven added to five equals two" is represented by expression 5-7x=2
What is Expression?An expression is combination of variables, numbers and operators.
The given sentence is "a number times negative seven added to five equals two"
Here let us consider the unknown number to be x.
As in the sentence we have a number times negative seven.
Times in the sentence means product. So the number x is multiplied with -7. i.e is -7x
Now a number times negative seven added to five.
This means 5 is added to -7x
-7x+5
"a number times negative seven added to five equals two" means -7x+5 is equal to two
-7x+5=2
5-7x=2
Hence the "a number times negative seven added to five equals two" is represented by expression 5-7x=2

What is the y-intercept and x-intercept of g(x)=-2x+6
Answer:
see below
Step-by-step explanation:
g(x)=-2x+6
To find the y intercept set x = 0
g(0) = -2(0) +6
g(0) = 6
The y intercept is 6
(0,6)
To find the x intercept set y = 0
0 = -2(x) +6
Subtract 6 from each side
0-6 = -2x+6-6
-6 = -2x
Divide each side by -2
-6/-2 = -2x/-2
3 = x
The x intercept is 3
(3,0)
Answer:
x-int : 3
y-int : 6
Step-by-step explanation:
in order to find x intercept, you set the function equeal to 0
0= -2x + 6
then solve for x
-6 = -2x
3=x
To solve for the y intercept, you plug in 0 for x
y = -2(0) + 6
then solve for y
y = 6

In 2005, the Federal Aviation Administration (FAA) updated its passenger weight standards to an average of 190 pounds in the summer (195 in the winter). This includes clothing and carry-on baggage. The FAA, however, did not specify a standard deviation. A reasonable standard deviation is 35 pounds. Weights are not Normally distributed, especially when the population includes both men and women, but they are not very non-Normal. A commuter plane carries 25 passengers. What is the approximate probability that, in the summer, the total weight of the passengers exceeds 5200 pounds
Answer: 0.0051
Step-by-step explanation:
Given the following :
Average Population weight (m) = 190
Population standard deviation (σ) = 35
Total weight of 25commuters (x) = 5200
Sample mean = 5200 /25 = 108
Sample standard deviation = standard error :
σ / √n = 35/√25 =
35/5 = 7
Zscore = (x - m) / standard error
Zscore = (208 - 190) / 7
Zscore = 18 / 7
= 2.57
P( Z > 2.57) = 1 - p(Z < 2.57)
P(z < 2.57) = 0.9949
1 - p(Z < 2.57) = 1 - 0.9949 = 0.0051
