Answer:
from the t-distribution table, at df = 7 and t = 2.23
Lies p-values [ 0.05 and 0.025 ]
Hence;
0.025 < p-value < 0.05
Step-by-step explanation:
Given that;
[tex]x^{bar}[/tex] = 6.5 gpm
μ = 5 gpm
n = eight runs = 8
standard deviation σ = 1.9 gpm
Test statistics;
t = ([tex]x^{bar}[/tex] - μ) / [tex]\frac{s}{\sqrt{n} }[/tex]
we substitute
t = (6.5 - 5) / [tex]\frac{1.9}{\sqrt{8} }[/tex]
t = 1.5 / 0.67175
t = 2.23
the degree of freedom df = n-1 = 8 - 1
df = 7
Now, from the t-distribution table, at df = 7 and t = 2.23
Lies p-values [ 0.05 and 0.025 ]
Hence;
0.025 < p-value < 0.05

Answer:
Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
Step-by-step explanation:
Luke and Seth each need to buy the same amount of fencing for their gardens. While Seth's garden is square in shape, Luke's garden is rectangular with the length 3 feet longer than Seth's. Luke's width is half of the length of his own garden. How much fencing did each buy?
A = Lw (Area equal length times width)
A = 48 (the garden's area is 48 ft2)
L = w + 2
We have values for our variables, so let's plug them in:
48 = w(w + 2)
Distribute:
48 = w2 + 2w
Subtract 48 from both sides:
0 = w2 + 2w - 48
AS you can see, we now have a quadratic. From here we need:
m + n = 2 and
m * n = -48
When we break up the quadratic into (w + m)(w + n)
48 is an even number divisible by 3, so it'll be also be divisible by 6:
48 / 6 = 8
8 + (-6) = 2
8 * -6 = -48, so:
0 = (w + 8)(w - 6) →→ 0 = w + 8, or 0 = w - 6
w = -8 or 6
We can't have a negative width, so it cannot be -8, therefore, the width is 6 ft. I'm sure you can find the length from here.

What is the volume of the rectangular prism?
512 in 3
64 in 3
256 in 3
128 in 3
Answer and Step-by-step explanation:
First, we need to know what the formula is for finding the volume of a rectangular prism.
The volume formula for a rectangular prism is as follows:
V = b (base) * w (width) * h (height)
Essentially, we just take the height, base, and width, and multiply them together. Order doesn't matter here.
So, let's multiply 8 by 8 by 4.
8 * 8 * 4 = V
64 * 4 = V
256 = V
256 [tex]in^{3}[/tex] is the answer.

Rambo-Conduit Corporation manufactures plastic conduit that is used in the cable industry. A conduit is a tube that encircles and protects the underground cable. In the process of making the plastic conduit, called extrusion, the melted plastic (resin) is pressed through a die to form a tube. Scrap is produced in this process. Information from the cost of production reports for three months is as follows, assuming that inventory remains constant:
May June July
Resin pounds input into the process 470,000 700,000 650,000
Price per pound X$1.50 X$1.50 X$1.50
Plastic material costs $493,000 $640,000 $677,000
Conversion costs $80,000 $120,000 $115,000
Conduit output from the process (feet) 800,000 1,200,000 1,130,000
Assuming that there is one-half pound of resin per foot of the finished product, determine the resin materials cost per foot of finished product for June.
a. $0.53
b. $0.60
c. $0.54
d. None of these choices are correct.
Answer:
The resin materials cost per foot of finished product for June is $0.53
Option a) $0.53 is the right answer
Step-by-step explanation:
Given the data in the question;
May June uly
Resin pounds input
into the process 470,000 700,000 650,000
Price per pound X$1.50 X$1.50 X$1.50
Plastic material costs $493,000 $640,000 $677,000
Conversion costs $80,000 $120,000 $115,000
Conduit output from
the process (feet) 800,000 1,200,000 1,130,000
Assuming that there is one-half pound of resin per foot of the finished product, determine the resin materials cost per foot of finished product for June.
Now;
Materials cost for June = $640,000
Number of Feet produced as output in June = 1,200,000
so
Material Cost per feet of finished product will be;
= $640,000 / 1,200,000
= $0.5333 ≈ $0.53
Therefore, the resin materials cost per foot of finished product for June is $0.53
Option a) $0.53 is the right answer
Lyn either travels by bus or walks
when she visits the shops.
The probability that she catches
the bus To the shops is 0.2
The probability that she catches
the bus FROM the shops is 0.6
0.2
Walk
a) Complete the tree diagram.
b) Show that the probability that Lyn
walks at least one way is 0.88.
I’m forced to write an explanation, sorry for the useless text
The probability tree has been drawn below and the probability that Lyn
walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks.
What is probability?The probability of an event occurring is defined by probability.
Do not take underestimate probability it has several uses in daily life whether forecasts like that.
As per the given probability tree,
(a)
The probability in branches adds to 1 thus,
0.2 + probability that she walks to the shop = 1
Probability that she walks to the shop = 1 - 0.2 = 0.8
The probability in the same branches multiplies as,
The probability that she took a bus to the shop x from the bus she again took the bus.
Similarly, the tree diagram has been drawn below.
(b)
The probability is 0.88 lies in that Lyn walks at least one way 0.88 is when she reaches the shop by bus and from the bus, she walks.
Hence "walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks".

Arbitron Media Research Inc. conducted a study of the iPod listening habits of men and women. One facet of the study involved the mean listening time. It was discovered that the mean listening time for a sample of 10 men was 37 minutes per day. The standard deviation was 13 minutes per day. The mean listening time for a sample of 16 women was also 37 minutes, but the standard deviation of the sample was 14 minutes. At the 0.10 significance level, can we conclude that there is a difference in the variation in the listening times for men and women?
Answer:
We reject H0; that there is significant evidence to support that there is difference in the variation in the listening times for men and women
Step-by-step explanation:
Given that :
n1 = 10 ; s1 = 13 ; n2 = 16 ; s2 = 14 ; α = 0.1
Null : H0 : σ1² = σ2²
Alternative : H1 : σ1² ≠ σ2²
To compute the test statistic ; using the Ftest:
F-test = σ2² / σ1² = 14² / 13²
F-test = 14²/13² = 196 / 169 = 1.1597
Decision region :
Reject Null, H0 ; if
Ftest < Fcritical
F critical at:
At α/2 = 0.10/2 = 0.05
df_numerator = 16 - 1 = 15
df_denominator = 10 - 1 = 9
Using F critical calculator :
Fcritical = 3.006
1.1597 < 3.006
Since, Ftest is lesser than Fcritical, then we reject H0

the rule for the distributive property is
Step-by-step explanation:
The Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Formally, they write this property as "a(b + c) = ab + ac". In numbers, this means, for example, that 2(3 + 4) = 2×3 + 2×4.

Answer:
41.67
Step-by-step explanation:
1.) Set up a proprotion
[tex]\frac{5.6}{x}[/tex]=[tex]\frac{20}{x+30}[/tex]
2.) Next solve! Cross multiply.
so we get..
5.6(x+30)= 20x
5.6x+168= 20x
5.6x-20x= -168
x= 11.67
3.) We have found x, but they are asking us for the whole length of AB! So just add 30 to x or 11.67
x+ 30= length of AB
11.67+30= 41.67
There are for the length of AB is 41.67!

Two professors are applying for grants. Professor Jane has a probability of 0.61 of being funded. Professor Joe has probability 0.29 of being funded. Since the grants are submitted to two different federal agencies, assume the outcomes for each grant are independent. Give your answer to four decimal places.
Required:
a. What is the probability that both professors get their grantsfunded? Give your answer to four decimal places.
b. What is the probability that at least one of the professors will befunded? Give your answer to four decimal places.
c. What is the probability that Professor Jane is funded but ProfessorJoe is not? Give your answer to four decimal places.
d. Given at least one of the professors is funded, what is theprobability that Professor Jane is funded but Professor Joe is not?
Answer:
a) 0.1769 = 17.69% probability that both professors get their grants funded.
b) 0.7231 = 72.31% probability that at least one of the professors will be funded.
c) 0.4331 = 43.31% probability that Professor Jane is funded but Professor Joe is not.
d) 0.5989 = 59.89% probability that Professor Jane is funded but Professor Joe is not
Step-by-step explanation:
a. What is the probability that both professors get their grants funded?
Jane has a 0.61 probability of being funded.
Joe has a 0.29 probability of being funded.
So
[tex]p = 0.61*0.29 = 0.1769[/tex]
0.1769 = 17.69% probability that both professors get their grants funded.
b. What is the probability that at least one of the professors will be funded?
None:
Jane has a 1 - 0.61 = 0.39 probability of not being funded.
Joe has a 1 - 0.29 = 0.71 probability of not being funded.
0.39*0.71 = 0.2769
At least one:
1 - 0.2769 = 0.7231
0.7231 = 72.31% probability that at least one of the professors will be funded.
c. What is the probability that Professor Jane is funded but Professor Joe is not?
Jane has a 0.61 probability of being funded.
Joe has a 1 - 0.29 = 0.71 probability of not being funded.
0.61*0.71 = 0.4331
0.4331 = 43.31% probability that Professor Jane is funded but Professor Joe is not.
d. Given at least one of the professors is funded, what is the probability that Professor Jane is funded but Professor Joe is not?
0.4331/0.7231 = 0.5989
0.5989 = 59.89% probability that Professor Jane is funded but Professor Joe is not
