Garth has a summer job and earns $9.32 per hour. One week, he works 16 34 hours. He deposits $150 in a bank and decides to use the rest of the money to buy raffle tickets. Each raffle ticket costs $0.50. How many raffle tickets can Garth buy?
Answer:
12 ticketsStep-by-step explanation:
Earning = $9.32 per hourWork hours = 16 3/4 = 16.75Earning in week:
$9.32*16.75 = $156.11Remaining money after he deposits $150:
$156.11 - $150 = $6.11How many raffle tickets can be bought:
$6.11/$0.50 = 12 and $0.11 remainsAnswer:
12 tickets

The waiting time for a bus has a uniform distribution between 2 and 13 minutes. What is the probability that the waiting time for this bus is less than 4.5 minutes on a given day
Answer: 0.2273
Step-by-step explanation:
Probability density function for uniform distribution is given by :-
[tex]f(x)=\dfrac{1}{b-a}[/tex], where x is uniformly distributed in [a,b].
Let x denotes the waiting time for this bus.
Given : The waiting time for a bus has a uniform distribution between 2 and 13 minutes.
Probability distribution function of x for interval [2,13] will be :-
[tex]f(x)=\dfrac1{13-2}=\dfrac{1}{11}[/tex]
Required probability : P(x<4.5) = [tex]\int^{4.5}_{2}f(x)\ dx[/tex]
[tex]=\int^{4.5}_{2}\dfrac1{11}\ dx\\\\=\dfrac1{11}[x]^{4.5}_{2}\\\\ = \dfrac1{11}(4.5-2)\\\\=\dfrac1{11}(2.5)\approx0.2273[/tex]
Hence, the probability that the waiting time for this bus is less than 4.5 minutes on a given day = 0.2273
Diet cola was on sale last week; it cost $10 for every 4 packs of cola. How much do 2 packs of cola cost?
Answer:
2 pack of cola would cost $5.
Step-by-step explanation:
the reason for this being is that
4 packs of cola = $10
2 is half of 4
5 is half of 10
$5<====
Answer:
I would say 5$
Step-by-step explanation:
You are going from 4 packs to 2 packs (so you are dividing by 2). So if you divide 10$ by 2 you get 5$
I hope this helps!

The volume of a right rectangle prism is found by multiplying the length of the base by the width of the base by the height of the prism. A right rectangular prism has a volume of 50 cubic inches. If the height of the prism is 4 inches, what is the area of the base of the prism?
9514 1404 393
Answer:
12.5 square inches
Step-by-step explanation:
The area of the base can be written as ...
B = LW
Then the volume formula ...
V = LWH
can be written in terms of the base area as ...
V = BH
The base area can be found by dividing by the height:
B = V/H = (50 in³)/(4 in) = 12.5 in²
The area of the base is 12.5 square inches.

a manufacturer says that the diagonal measurement of a laptop computer is 16 inches. Find the relative error of this measurement to the nearest tenth.
A. 0.6%
B.1.6%
C.3.1%
D.6.3%
Answer:
As this is incomplete, it lacks the value of actual error.
Here, we do not know the actual value. so let's assume it is 1 inch
Relative Error = 6.25 % ≈ 6.3% = D
Step-by-step explanation:
As this is incomplete, it lacks the value of actual error.
We are asked to calculate the relative of the measurement.
Relative error formula = Actual error/Measurement x 100
Here, we do not know the actual value. so let's assume it is 1 inch
Actual value = 1 inch
Measurement = 16 inch
Relative Error = 1/16 x 100
Relative Error = 6.25 % ≈ 6.3% = D
D. 6.3%

A publisher reports that 55% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 280 found that 51% of the readers owned a laptop. Make the decision to reject or fail to reject the null hypothesis at the 0.05 level.
Answer:
We fail to reject the null hypothesis, we accept H₀
Step-by-step explanation:
Population proportion p₀ = 55 % p₀ = 0,55
Sample size n = 280
Sample mean p = 51 % p = 0,51 q = 0,49
n*p and n*q are both bigger than 10 therefore we can approximate the binomial distribution to a normal distribution
Test Hypothesis
Null Hypothesis H₀ p = p₀
Alternative Hypothesis Hₐ p ≠ p₀
Significance level is α = 0,05 but we have a two-tail test then
α/2 = 0,025
z(c) = - 1,96
Computing z(s)
z(s) = ( p - p₀ ) / √(p*q)/n
z(s) = ( 0,51 - 0,55 ) / √(0,51*0,49)/280
z(s) = - 0,04 * 16,73 / 0,5
z(s) = - 1,34
Comparing
z(s) and z(c)
- 1,34 < - 1,96
| z(s) | < | z(c)|
Then z(s) is in the acceptance region, we accept H₀

The lengths of a professor's classes has a continuous uniform distribution between 49.29 min and 55.55 min. If one such class is randomly selected, find P54
Answer:
52.6704
Step-by-step explanation:
The lengths of a professor's classes has a continuous uniform distribution between 49.29 min and 55.55 min
Let x = 49.29, y=55.55
Percentile(P) = 54/100 = 0.54
P54 = x+(y-x)p
P54 = 49.29 + (55.55-49.29)*0.54
P54 = 49.29 + 6.26*0.54
P54 = 49.29 + 3.3804
P54 = 52.6704
