Answer:
[tex]\frac{y+5}{\frac{1}{3}x}\text{ or }{\frac{3y+15}{x}[/tex]
Step-by-step explanation:
The quotient of two numbers [tex]x[/tex] and [tex]y[/tex] can be written as [tex]\frac{x}{y}[/tex], the first number mentioned being the numerator.
In this case, the first value mentioned is 5 more than a number y, which can be represented as [tex]y+5[/tex]. This is our numerator.
The second value mentioned is 3 times less than a number x, which can be represented as [tex]\frac{1}{3}x[/tex] or [tex]\frac{x}{3}[/tex]. This is our denominator.
Thus, the quotient of these two numbers is [tex]\frac{y+5}{\frac{x}{3}}=\frac{y+5}{1}\cdot \frac{3}{x}=\frac{3(y+5)}{x}=\boxed{\frac{3y+15}{x}}[/tex]

A uniform probability distribution is a continuous probability distribution where the probability that the random variable assumes a value in any interval of equal length is a.different for each interval. b.the same for each interval. c.at least one. d.zero.
Answer:
Hence the correct option is Option b that is the same for each interval.
Step-by-step explanation:
The PDF for Uniform distribution in [a,b] is given by
[tex]f(x)=\frac{1}{b-a}~~~~~~a\leq x\leq b[/tex]
So the probability that the random variable assumes a value in [a,b] is given by
[tex]\int_{a}^{b}f(x)dx=\int_{a}^{b}\frac{1}{b-a}dx=1[/tex]
Therefore the correct option is b. the same for each interval.

A box is shaped like a square prism. The box is 10 centimetres high and it’s volume is 150 cubic centimetres.
Answer:
B I hope
Step-by-step explanation:
The length of the base of a square prism is 3.872 cm and the surface area of a square prism is 184.9 cm ²
Volume of a square prismLet h is the height length of the prism and a is the length of base edge.
then the volume is a²h and the surface area is 2a²+4ah
How to base length?(a) The volume of a square prism is 150 cm³ and 10 cm is height length
Let a is the length of base edge.
We know the volume is a²h.
Substitute the values
a²(10) = 150
a² = 15
a = √15
a = 3.872 cm
Since length of base is 3.872 cm.
How to find the surface area of a square prism?(b) The height length of the prism is 10 cm and the base edge length is √15 cm.
We know the surface area is 2a²+4ah
Substitute the values
S = 2(√15)² + 4 (3.87 )(10)
= 2(15) + 40(3.87)
= 30 + 154.91
= 184.9 cm ²
Since the surface area of a square prism is 184.9 cm ².
What is the area of a right triangle with side lengths 7,24, and 25?
Answer:
Area = 84 square unit
Step-by-step explanation:
Given the triangle is right angle triangle. According to Pythagoras theorem, the largest amount the sides is the hypotenuse. and the others are base and height respectively.
Therefore, hypotenuse = 25, base = 7, height = 24
[tex]Area \ of \ triangle = \frac{1}{2} \times \ base \times height[/tex]
[tex]= \frac{1}{2} \times 7 \times 24 \\\\= 7 \times 12 \\\\= 84 \ square \ unit[/tex]
Answer:
A = 84 units^ 2
Step-by-step explanation:
The longest side length is also the hypotenuse of this right triangle: 25. Therefore the leg lengths must be 7 and 24. The legs are perpendicular to one another. If we let the base be 7 and the height 24, then the area of the triangle is A = (1/2)(base)(height), or
A = (1/2)(7)(24) = 84 units^ 2
A value meal package at Ron's Subs consists of a drink, a sandwich, and a bag of chips. There are 4 types of drinks to choose from, 5 types of sandwiches, and 3 types of chips. How many different value meal packages are possible
Answer:
60 different meal packages are possible.
Step-by-step explanation:
Fundamental counting principle:
States that if there are p ways to do a thing, and q ways to do another thing, and these two things are independent, there are p*q ways to do both things.
In this question:
4 types of drinks
5 types of sandwiches.

Two advertising media are being considered for promotion of a product. Radio ads cost
$400 each, while newspaper ads cost $600 each. The total budget is $7,200 per week.
The total number of ads should be at least 15 and at least 2 ads of each type (Radio and
newspaper) should be considered. Each newspaper ad reaches 6,000 people, while each
radio ad reaches 2,000 people. The company wishes to reach as many people as possible
while meeting all the constraints stated.
1.
Write the constraints and the objective function for this problem?
(3 pts)
2.
How many ads of each type should be placed?
(5 pts)
Answer:
1. 1. The constraints are as follows -
a) Limited weekly budgets
b) Limited ads requiring that there should be at least 15 and at least 2 ads of each type (Radio and newspaper)
c) Newspaper ad being costly reach larger population segment as compared to the radio ads which is cheaper than newspaper ad but reaches only a small portion of population
2. 6 newspaper adds and 9 radio adds
Step-by-step explanation:
1. The constraints are as follows -
a) Limited weekly budgets
b) Limited ads requiring that there should be at least 15 and at least 2 ads of each type (Radio and newspaper)
c) Newspaper ad being costly reach larger population segment as compared to the radio ads which is cheaper than newspaper ad but reaches only a small portion of population
The objective function
Maximum number of people per week = 6000 * number of newspapaer ads + 2000 * number of radio ads
b) $7,200
Minimum radio adds = 3 this will cost 3 * $400 = $1200
Remaining money = $7200 - $1200 = $6000
Cost of one add of news paper = $ 6000/$600 = 10
But the minimum ads need to be 15
So, If Newspaper adds are reduced to 6, the radio adds will be 9 giving a sum of 15

Polynomials can sometimes be divided using the simple methods shown on Dividing Polynomials.
But sometimes it is better to use "Long Division" (a method similar to Long Division for Numbers)
Numerator and Denominator
We can give each polynomial a name:
x² + 2x -7 (numerator)
_________
x-2 (denominator)
[tex] \times - {}^{2} \sqrt{ \times {}^{2} } + 2 \times - 7[/tex]
Both polynomials should have the "higher order" terms first (those with the largest exponents, like the "2" in x2).
then :
divide: the first term of the numerator
by the first term of denominator and put that answer
multiply the denominator by that answer, put that below the numerator
subtract to create a new polynomial
repeat using the polynomial

The average full-time faculty member in a college works an average of 53 hours per week. a) If we assume the standard deviation is 2.8 hours, what percentage of faculty members work more than 58.6 hours a week?
Answer:
2.28% of faculty members work more than 58.6 hours a week.
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 z-score 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 p-value, we get the probability that the value of the measure is greater than X.
The average full-time faculty member in a college works an average of 53 hours per week. Standard deviation of 2.8 hours.
This means that [tex]\mu = 53, \sigma = 2.8[/tex]
What percentage of faculty members work more than 58.6 hours a week?
The proportion is 1 subtracted by the p-value of Z when X = 58.6. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{58.6 - 53}{2.8}[/tex]
[tex]Z = 2[/tex]
[tex]Z = 2[/tex] has a p-value of 0.9772
1 - 0.9772 = 0.0228
0.0228*100% = 2.28%
2.28% of faculty members work more than 58.6 hours a week.

Shawn, Ryan, and Dominic ate a whole pizza.Shawn ate 1/6 of the pizza, Ryan at 1/2 of the pizza and Dominic ate the rest how much pizza did Dominic eat
Answer:
Dominic ate [tex]\frac{2}{6}[/tex] of the pizza.
Step-by-step explanation:
First you want to convert the fractions so they all have the same denominator (bottom number in the fraction.) That will make it a lot easier to add and subtract with them.
[tex]\frac{1}{2}[/tex] = [tex]\frac{3}{6}[/tex]
So Shawn ate 1/6 of the pizza, and Ryan ate 3/6 of the pizza. To find what else makes up the whole pizza (what Dominic ate) we add 1/6 and 3/6, then subtract from the whole.
[tex]\frac{1}{6}[/tex] + [tex]\frac{3}{6}[/tex] = [tex]\frac{4}{6}[/tex]
[tex]\frac{6}{6}[/tex] - [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{6}[/tex]
Therefore Dominic ate [tex]\frac{2}{6}[/tex] of the pizza.
