Answer:
The answers to the questions are well numbered below.
Step-by-step explanation:
We have arrival rate
λ = 7 in every 10 minutes = 0.7
Service time u = 7 minutes
1. Average time a car is in system
W = 1/u - λ
= 1/7-0.7
= 0.1587
= 0.16 to 2 decimal places
2. Average number of cars in system
= λ/u-λ
= 0.7/7-0.7
= 0.1111
= 0.11 to 2 decimal places
3. Average time that cars spend to receive service
= λ/u(u-λ)
= 0.7/7(7-0.7)
= 0.01587
= 0.016 to 2 decimal places
4. Average number of cars in line behind customer receiving service
= λ²/u(u-λ)
= 0.7²/7(7-0.7)
= 0.49/44.1
= 0.011 to 2 decimal places
5. Probability no cats at window
1-λ/u
= 1-0.7/7
= 0.9 = 9%
6. Percentage of time postal clerk is busy
= λ/u = 0.7/7 = 0.1 = 10%
7. Probability of exactly 2 cars
= λ²e^-λ/2!
= 0.7²e^-0.7/2!
= 0.1217
= 12.17%

What is the remainder of 46 divided by 8?
Answer:
The remainder is 6 !
Step-by-step explanation:
The remainder of the equation A = 46 / 8 is r = 6
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the remainder of the equation be denoted as = r
Let the dividend number be = 46
Let the divisor number be = 8
Now , the equation is represented as = A
The value of A is given by
A = 46 / 8
Now , the remainder will be
5 x 8 = 40
Substituting the values in the equation , we get
Dividend - 40 = 6
Therefore , the remainder of the equation A is 6
Hence , The remainder of the equation A = 46 / 8 is r = 6

The average time it takes for a person to experience pain relief from aspirin is 25 minutes. A new ingredient is added to help speed up relief. You run an experiment to verify if the new product is better. You test out the new aspirin on 70 people. Those seventy people had a mean time of 24 minutes and 12 seconds with a standard deviation of 3 mins. Find the test statisic and p-value for your experiment.
Answer:
-2.23 ; 0.012874
Step-by-step explanation:
Given that :
Population mean (μ) = 25 minutes
Same mean (x) = 24min 12 seconds = 24.2 minutes
Standard deviation σ = 3
Sample size (n) = 70
Test statistic :
Using the relation :
Tstatistic = (x - m) / σ/sqrt(n)
Tstatistic = (24.2 - 25) / (3/sqrt(70)
Tstatistic = - 0.8 / 0.3585685
Tstatistic = - 2.2310939
= - 2.23
The P value can be obtained using a. P value Calculator :
P at α = 95% and test statistic = - 2.23
Hence, p = 0.012874 using calculator
The systolic blood pressure (BP) of adults in the USA is nearly normally distributed with a mean of 117 and standard deviation of 17 . Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher. (a) Around what percentage of adults in the USA have stage 2 high blood pressure
Answer:
the percentage of adults have stage 2 high blood pressure is 0.0057
Step-by-step explanation:
The computation of the percentage of adults have stage 2 high blood pressure is shown below;
Given that
mean = 117
Standard deviation = 17
and, the sample is 160
Now based on the above information,
The percentage is
= (Sample - mean) ÷ (standard deviation)
= (160 - 117) ÷ (17)
= 2.529
p(z>2.53) = 0.0057
hence, the percentage of adults have stage 2 high blood pressure is 0.0057

c. 3 bananas cost $0.99. At this rate, how much do 5 bananas cost? Explain how you know.
Answer:
$1.65
Step-by-step explanation:
You can get the cost of each banana by using the division operation. All you have to do is to divide $0.99 by 3.
0.99 ÷ 3 = $0.33Each banana costs $0.33
Now that you know the cost of each banana, you may now get the cost of 5 bananas by using the multiplication operation. All you have to do is to multiply $0.33 by 5.
0.33 x 5 = $1.65Therefore, 5 bananas cost $1.65.

what's the rate of change and is it a linear function
Answer:
The rate of change is -4.5 and the relation of the table is a linear function
Step-by-step explanation:
Linear function.
A linear function can be identified because the rate of change is constant at every point of its domain.
The graph of a linear function is a straight line with a constant slope.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We'll show the relation shown in the table is a linear function. We'll calculate the slope for any random pair of points. For example, using (2,83) and (3,78.5):
[tex]\displaystyle m=\frac{78.5-83}{3-2}=-4.5[/tex]
Now for (7,60.5) and (14,29):
[tex]\displaystyle m=\frac{29-60.5}{14-7}=\frac{-31.5}{7}=-4.5[/tex]
Proceeding in a similar way with any pair of points, the slope will always result in the same value, thus the rate of change is -4.5 and the relation of the table is a linear function.

In a recent survey of 1002 people, 701 said that they voted in a recent presidential election. Voting records show that 61% of eligible voters actually did vote. a) Find the 95% confidence interval estimate of the proportion of people who say that they voted.
Answer:
The 95% confidence interval estimate of the proportion of people who say that they voted
(0.67122 , 0.72798)
Step-by-step explanation:
Step(i):-
In a recent survey of 1002 people, 701 said that they voted in a recent presidential election.
Sample proportion
[tex]p = \frac{x}{n} = \frac{701}{1002} = 0.6996[/tex]
Step(ii)
The 95% confidence interval estimate of the proportion of people who say that they voted
[tex](p^{-} - Z_{0.05} \sqrt{\frac{p(1-p)}{n} } , p^{-} + Z_{0.05} \sqrt{\frac{p(1-p)}{n} } )[/tex]
[tex](0.6996 - 1.96\sqrt{\frac{0.6996(1-0.6996)}{1002} } , 0.6996 + 1.96 \sqrt{\frac{0.6996(1-0.6996)}{1002} } )[/tex]
(0.6996 - 1.96 X 0.01448 , 0.6996 + 1.96 X 0.01448)
(0.6996 - 0.02838 , 0.6996 + 0.02838)
(0.67122 , 0.72798)
Final answer:-
The 95% confidence interval estimate of the proportion of people who say that they voted
(0.67122 , 0.72798)
Emma wants to build a fence around the perimeter of her lawn. Each foot of fence costs $2. The rectangular lawn has an area of 364 square feet and a width of 14 feet. How much will the entire fence cost?
Answer:
[tex]\$160[/tex]
Step-by-step explanation:
To find the cost of the entire fence, we need to first determine the lawn's length before calculating its perimeter.
Area of rectangular lawn = [tex]lw[/tex] (formula for the area of a rectangle)
[tex]364=14l[/tex]
[tex]l=26[/tex] feet
Now that we have the lawn's length and width, we can calculate the perimeter:
Perimeter [tex]= 2l+2w[/tex] (formula for the perimeter of a rectangle)
[tex]=2(26)+2(14)[/tex]
[tex]=80[/tex] feet
Since each foot of lawn costs $2, then the cost of the entire fence will be:
[tex]80\times2 = \$160[/tex]
∴ The entire fence costs [tex]\$160[/tex].

determine the truth values of p, q, and r that would make the statement false. Explain your reasoning. p→(q∨~r)
======================================
Explanation:
For a conditional to be false, the antecedent must be true and the conclusion must be false. So the format is (true) --> (false) for the overall conditional to be false.
Since the antecedent must be true, this means p = true. We can shorten this to say p = T, where T stands for "true".
Now we must make (q v ~r) be false.
This is only possible if both pieces q and ~r are false. An "or" statement, aka disjunction, is true if either piece is true; otherwise it's false.
So q = F, where F stands for "false" and ~r = F as well.
If ~r = F, then r = T. Recall the squiggly line or tilde is basically the negation operator. It does the opposite of the statement.
