Answer:
That is an indeterminant question, as we do not know the amount of fax time used of each machine and it certainly won't be equal. However, based on whats given you could say
Step-by-step explanation:
5 hrs. use / 0.25 service time = 20 / 3 machines = 6.67. Probability of needing to service 2 machines simultaneously is: 1/6.67 = 15%.
The Probability of needing to service 2 machines simultaneously is 15%.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
The school of business has 3 fax machines.
and, It takes him 15 minutes to replace the toner cartridge.
So, 5 hours / 0.25 service time
= 20 / 3 machines
= 6.67.
Then, the Probability of needing to service 2 machines simultaneously
= 1/6.67
= 15%.
Hence, the probability is 15%.

A boat takes 2 hours to travel 15 miles upriver against the current. If the rate of the boat in still water is 13 miles per hour what is the rate of the current?
Answer:
The rate of the current is 5.5 miles per hour
Step-by-step explanation:
Relative Speeds
The boat takes 2 hours to travel 15 miles upriver against the current. The speed is 15/2 = 7.5 miles per hour.
Since the boat in still water can travel at 13 miles per hour, it means the current subtracts its speed from the speed of the boat:
Vcurrent = 13 mi/h - 7.5 mi/h
Vcurrent = 5.5 mi/h
The rate of the current is 5.5 miles per hour

Strongest value = 0.5929
Step-by-step explanation:
Given:
Choices
0.691
-0.14
-0.24
-0.77
Computation:
0.691² = 0.477481
-0.14² = 0.0196
-0.24² = 0.0576
-0.77² = 0.5929
Weakest value = 0.0196
Strongest value = 0.5929
The time needed for all college students to complete a certain paper-and-pencil maze follows a normal distribution with a population mean of 30 seconds and a population standard deviation of 3 seconds.
You wish to see if the mean time μ (where μ stands for population mean) is changed by vigorous exercise, so you have a group of nine college students exercise vigorously for 30 minutes and then complete the maze. It takes them an sample average of 31.2 seconds to complete the maze. Use this information to test the hypotheses:
H0: μ = 30,
Ha: ≠30
at the significance level of 0.01.
You conclude:
a) There is not enough evidence to support the claim.
b) There is enough evidence to support the claim.
Answer:
The correct option is a
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 30\ seconds[/tex]
The standard deviation is [tex]\sigma = 3 \ seconds[/tex]
The sample size is n = 9
The null hypothesis is [tex]H_o: \mu = 30[/tex]
The alternative hypothesis is [tex]H_a : \mu \ne 30[/tex]
The level of significance is [tex]\alpha = 0.01[/tex]
The sample mean is [tex]\= x = 31.2[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{ \= x - \mu }{ \frac{\sigma}{\sqrt{n} } }[/tex]
=> [tex]z = \frac{ 31.2 - 30}{ \frac{3}{\sqrt{9} } }[/tex]
=> [tex]z = 1.2[/tex]
From the z table the area under the normal curve to the right corresponding to 1.2 is
[tex]P(Z > 1.2) = 0.11507[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(Z > 1.2)[/tex]
=> [tex]p-value = 2 *0.11507[/tex]
=> [tex]p-value = 0.230[/tex]
From the value obtained w can see that
[tex]p-value > \alpha[/tex] hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is there is not enough evidence to support the claim

Determine the number of white paints per yellow paints
The interpretation of this question is to determine the slope or rate of the graph.
Represent the yellow paints with x and the white with y
So, we have:
[tex](x_1,y_1) = (3,21)[/tex]
[tex](x_2,y_2) = (9,63)[/tex]
The slope is then calculated as:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{63- 21}{9 - 3}[/tex]
[tex]m = \frac{42}{6}[/tex]
[tex]m = 7[/tex]
Hence, 7 white paints are needed per 1 yellow paint

in the term 4p, the variable p is raised to the power of 0 or 1 ?
Answer:
1
Step-by-step explanation:
anything raised to the power of 0 would equal 1 and p doesn't equal 1 here.
Answer:
4 or 0
Step-by-step explanation:
well if the variable p became 0 the term 4p would look more like this 4(0) or 4 * 0 making the answer be 0
If the variable was changed into 1 the term 4p would become 4(1) or 4 * 1 as of such the answer would be 4.
now if you are raising p to a 0 so the term is more like this: 4p to the power of 0 then your answer would be 1. Because p would change to 0.
Now if you had 4p to the raised power of 1 then your answer would be 4 because p was changed to a 4.

Multiply 8.88 x 10 . Explain the shift of the digits and the change in the value of each digit.
Answer:
Since it is multiplied by ten, its basically multiplying 8.88 by 1 and moving the decimal to the right once. Multiplying numbers by 10s, 100s etc. means you have to shift the decimal point to the right based on a number of zeros multiplied.

The cube of y varies directly as z. When y = 8, z = 8. Heather’s work finding the value of y when z = 64 is shown:
y^3 = kz
8 = k x 8
1 = k
y^3 = 1 x 64
y^3 = 64
y = 4
What is the first error, if any, in Heather’s work?
A. She did not make any errors.
B. She substituted incorrectly when calculating the constant of variation.
C. She cubed the wrong variable when making her equation.
D. She used an equation that models inverse variation instead of direct variation.
Answer:
Step-by-step explanation:
If the cube of y varies directly as z, then;
y³ ∝ z
y³ = kz
k is the constant of proportionality
y³ = kz
When y = 8, z = 8.
8³ = 8k
k = 8³ /8
k = 64
To get the value y when z = 64, we will have;
y³ = kz
y³ = 64(64)
y³ = 4096
y= ∛4096
y = 16
Hence the value of y is 16
