If the population standard deviation of the stopping distance is provided as σ = 6.7 feet. Estimate the average stopping distance of all Model A tires with a 94% confidence interval.
Complete Question
The complete question is shown on the first and second uploaded image
Answer:
The estimate of the average stopping distance of all model A tires with a 94% confidence interval is
[tex]132.94 < \mu < 144.86[/tex]
Step-by-step explanation:
From the question we see that
The sample size is n = 8
The population standard deviation is [tex]\sigma = 6.7[/tex]
Generally the sample mean is mathematically represented as
[tex]\= x = \frac{\sum x_i }{n}[/tex]
=> [tex]\= x = \frac{ 145 + 152 + \cdots + 133}{8}[/tex]
=> [tex]\= x = 138.9[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 94 ) \%[/tex]
=> [tex]\alpha = 0.04[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = n - 1[/tex]
=> [tex]df = 8 - 1[/tex]
=> [tex]df = 7[/tex]
Because the n < 30 we will making use of the t table
Generally from the t distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of [tex]df = 7[/tex] is
[tex]t_{\frac{\alpha }{2}, 7 } = 2.517 [/tex]
Generally the margin of error is mathematically represented as
[tex]E = t_{\frac{\alpha }{2} , df} * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 2.517 * \frac{6.7 }{\sqrt{8} }[/tex]
=> [tex]E =5.96 [/tex]
Generally 94% confidence interval is mathematically represented as
[tex]\= x -E < \mu < \=x +E[/tex]
=> [tex]138.9 -5.96 < \mu < 138.9 + 5.96[/tex]
=> [tex]132.94 < \mu < 144.86[/tex]
Robert bought 3 baseball caps for the same amount and 1 baseball jersey that cost $45. Without tax, the total cost of the items is $90. What is the cost of each baseball cap?
Answer:
Unitary cost= $15
Step-by-step explanation:
First, we need to calculate the total cost of the baseball caps:
Total cost baseball caps= 90 - 45
Total cost baseball caps= $45
Now, the unitary cost of each baseball caps:
Unitary cost= total cost / number of units
Unitary cost= 45/3
Unitary cost= $15

Jamal can run 1 mile in 5.05 minutes. If Jamal maintains this pace during a 5-kilometer (5K) race, he expects to break the course record of 15.25 minutes. Is Jamal's expectation reasonable? Explain.
Answer:
The expectation is reasonable
Step-by-step explanation:
Since Jamal runs 1 mile in 5.05 minutes, and expected to run 5 km in 15.25 minutes, we need to find if this is true. So, we need to find if he can actually run 5 km in 15.25 minutes.
Now 1 mile = 1609 m and 5 km = 5000 m. So, 5 km = 5000 m × 1mile/1609 m
5 km = 5000/1609 mile
Also since Jamal runs 1 mile in 5.05 minutes, the time it takes to run 5 km = 5000/1609 mile is 5000/1609 mile × 5.05 minutes/1 mile = 25,250/1609 minutes = 15.69 minutes.
Since our calculation shows that Jamal runs a 5 kilometer race in 15.69 minutes, the expectation that he will break the record in 15.25 minutes is reasonable. He can only break the record if he runs faster since there is a difference of 15.69 - 15.25 minutes = 0.44 minutes = 0.44 × 60 = 26.4 seconds which is quite a short time. So the expectation is reasonable.

what lines are perpendicular to 2x-7y=-25
Answer:
Step-by-step explanation:
Given the line 2x-7y = -25
First let us get the slope of the line:
Rewrite the equation in the form y = mx+c
2x-7y = -25
-7y = -2x-25
y = -2x/-7-25/-7
y = 2/7 x +25/7
The slope of the line is 2/7
Ffor two lines to be perpendicular, the product of their slope must be -1
mM = -1
m(2/7)= -1
2m = -7
m = -7/2
Hence the lines perpendicular to the given line must be a line that has a slope of -7/2. Since we are not given option, we can say example of such line is y = -7/2 x + 15
alexandria earned a 64 on her test. she studied and went to her teachers remediation and earned a 92 on her retake. what was her percent of change on her tests? round to the nearest whole number
Answer:
28%
Step-by-step explanation:
92-64=28
The percentage change in Alexandria's marks would be; 44%
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100. Percentage is the ratio of the number for which you want to find percentage to the total number with which you want to compare or out of and multiply this ratio with 100.
The percentage of change = (change in amount / original amount ) x 100
Alexandria's marks in first attempt = 64
Alexandria's marks in retake = 92
Then the Change in marks = 92-64 = 28
Thus Percentage of change on her tests
= ( change in marks / initial marks) ×100
=( 28/64)×100
= 43.75 %
≈ 44 %
Therefore, the percentage change in Alexandria's marks would be; 44%

Step-by-step explanation:
The point ( -3 1/2, -1 1/4 ) on the coordinate plane is shown in the figure
How can we perceive cartesian coordinate plane?The cartesian coordinate plane is an infinite 2 dimensional plane. Any 2 dimensional figure can be drawn on an infinite 2d plane. Each of the point of a cartesian plane is tracked by a location.
It is the perpendicular distance of that point from the horizontal axis and vertical axis, usually named x-axis and y-axis. The location is then written as: (a,b), where 'a' is that point's shortest distance from the y-axis and called x-coordinate of that point, and 'b' is that point's shortest distance from the x-axis, and called y-coordinate of that point.

To rent a certain meeting room, a college charges a reservation fee of $18 and an additional fee of $6 per hour. The chemistry club wants to spend less than $48 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room? Use t for the number of hours. Write your answer as an inequality solved for .
Answer: t = 1 hour, 2 hours, 3 hours or 4 hours
Step-by-step explanation:
Reservation fee = $18
Additional fee per hour = $6 per hour
Number of hours to spend = t
The information in the question can be expressed as:
$18 + $6t < $48
$6t < $48 - $18
$6t < $30
t < $30/$6
t < 5
Since the number of hours will be less than 5 hours, the possible numbers of hours the chemistry club could rent the meeting room will be:
1 hour, 2 hours, 3 hours or 4 hours

el salario mensual de mi papa es de 12825 y paga la renta de la casa que equivale a una tercera parte de su sueldo cuanto paga de renta cuanto le queda para los demas gastos
Answer:
Mi papa paga $ 4275 por la renta de la casa y le queda $ 8550 para el ahorro y los demás gastos.
Step-by-step explanation:
Mi padre recibe su paga, dedica una tercera parte para pagar la renta de la casa y dispone del resto, es decir, las dos terceras partes, para ahorro y demás gastos. Entonces, calculo los rubros correspondientes:
Rubro dedicado al pago de la renta de la casa
[tex]x = \$\,12825\times\frac{1}{3}[/tex]
[tex]x = \$\,4275[/tex]
Rubro dedicado al ahorro y los demás gastos
[tex]y = \$\,12825-x[/tex]
[tex]y =\$\,12825-\$\,4275[/tex]
[tex]y = \$\,8550[/tex]
Mi papa paga $ 4275 por la renta de la casa y le queda $ 8550 para el ahorro y los demás gastos.
A designer is trying to build the ideal sized fish tank for a customer. It must hold exactly 24 cubic feet of water and can only be 4 feet in height. If the designer increases the width of the fish tank, what must happen to the length of it so that the volume remains the same? A. The length must stay the same. B. The length must decrease. C. The length must increase.
Answer:
B. The length must decrease
Step-by-step explanation:
Given;
maximum volume of the tank, V = 24 ft³
maximum height of the tank, h = 4 ft
let the width of the tank = w
let the length of the tank = L
Volume of the tank is given by;
V = Lwh
L = V / (hw)
L = 24 / (4w)
L = 6/w
L is inversely proportional to w; an increase in w (width) will cause a decrease in L (length)
Therefore, If the designer increases the width of the fish tank, "The length must decrease"

Step-by-step explanation:
Given f(x) = 6(1 - x), what is the value of f(-8)?
F(-8)=6(1--8) -- plug -8 into f(x) and x spots.
F(-)8=6(9) ---then solve
F(-8)=54 --- so the function to f(-8) is 54
