A gain of seven yards in football is represented by 7. What number represents a loss of
seven yards?
A 0
B. 7
C. -(-7)
D. -7
Answer:
D. -7
Step-by-step explanation:
Since positive 7 represents a gain of seven yards, a loss would be represented by a negative number.
So, a loss of seven yards will be represented by -7.
So, the correct answer is D. -7

Step-by-step explanation:
The midpoint of QR is (4, -1).
Q = (3.1)
What are the coordinates of point R?
Answer:
(5,-3)
Step-by-step explanation:
Given that,
The coordinates of Q = (3,1)
The midpoint of QR = (4,-1)
We need to find the coordinates of point R.
We know that, according to mid-point theorem,
[tex](x_m,y_m)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
Let (x₂,y₂) be the coordinates of point R.
So,
[tex](4,-1)=(\dfrac{3+x_2}{2},\dfrac{1+y_2}{2})\\\\\dfrac{3+x_2}{2}=4\ and\ \dfrac{1+y_2}{2}=-1\\\\3+x_2=8\ and\ y_2+1=-2\\\\x_2=5\ and\ y_2=-3[/tex]
So, the coordinates of point R is (5,-3).
A drawing of a building is 12-inches high. The scale in the drawing shows 1/2 inch equals 100 feet. What is the actual height, in feet, of the building?
Answer:
200ft
Step-by-step explanation:
100ft = 1/2 ft
12in = 1 ft
1/2 * 2= 1ft
1ft or 12in = 200ft
The new Fore and Aft Marina is to be located on the Ohio River near Madison, Indiana. Assume that Fore and Aft decides to build a docking facility where one boat at a time can stop for gas and servicing. Assume that arrivals follow a Poisson probability distribution, with an arrival rate of 8 boats per hour, and that service times follow an exponential probability distribution, with a service rate of 10 boats per hour. The manager of the Fore and Aft Marina wants to investigate the possibility of enlarging the docking facility so that two boats can stop for gas and servicing simultaneously.
A. What is the probability that the boat dock will be idle? Round your answer to four decimal places.
P0=
B. What is the average number of boats that will be waiting for service? Round your answer to four decimal places.
Lq=
C. What is the average time a boat will spend waiting for service? Round your answer to four decimal places.
Wq=
D. What is the average time a boat will spend at the dock? Round your answer to four decimal places.
W=
E. If you were the manager of Fore and Aft Marina, would you be satisfied with the service level your system will be providing? Round your answers to whole numbers.
Because the average wait time is ____ seconds. Each channel is idle ____ % of the time.
Answer:
A.) 0.2
B.) 3.2
C.) 0.4
D.) 0.5
Step-by-step explanation:
Arrival rate, λ = 8 per hour
Service rate, μ = 10 boats per hour
1.)
Probability that boat dock will be idle, P0:
P0 = 1 - λ/μ
P0 = 1 - 8/10
P0 = 1 - 0.8
P0 = 0.2
Average number of boats waiting for service :
Lq = λ² ÷ μ(μ - λ)
Lq = 8² ÷ 10(10- 8)
Lq = 64 ÷ 10(2)
Lq = 64 ÷ 20
Lq = 3.2
Average time spent waiting for service, Wq :
Wq = λ ÷ μ(μ - λ)
Wq = 8 ÷ 10(10- 8)
Wq = 8 ÷ 10(2)
Wq = 8 / 20
Wq = 0.4 hour
Wq = 0.4 * 60 = 24 minutes
Average time spent at the dock :
1 ÷ (μ - λ)
1 ÷ (10 - 8)
1 ÷ 2
= 0.5 hour
= 0.5 * 60 = 30 minutes
A boot has been designed which can be immersed for 12 hours without leaking. Five hundred pairs of the boots are tested and the time until first leakage is measured. The average time until first leakage for the sample is 12.25 hours with a standard deviation of 3.0 hours. Answer the following: 1) Find the p-value to test the claim that the average time until first leakage for the hunting boot is at least 12 hours.
Answer:
0.0312
Step-by-step explanation:
Given :
Mean or average time, xbar = 12.25
Standard deviation, s = 3
Sample size, n = 500
The test statistic :
(x - xbar) ÷ (s/sqrt(n))
(12 - 12.25) ÷ 3/sqrt(500)
-0.25 ÷ 0.1341640
Test statistic = - 1.863
The Pvalue :
P(Z < - 1.863) = 1 - P(Z ≤ 1.863)
P(Z < - 1.863) = 0.0312
Hence, the Pvalue = 0.0312

is there any other ones that are mathematical sentences ?
Answer:
4-d=8
Step-by-step explanation:
First, you must know what a mathematical sentence and a variable is. A mathematical sentence is equivalent (same) as an equation.
To be an equation/mathematical sentence,
You need the following:
~ Numbers/variables
~ Equal sign
A variable is just an unknown number (It's still a number, you just don't know what it is yet- think- VARI is the same meaning as vary, the number can vary.)
Let's look back at the problem.
4-d=8
Has an equal sign
Has both numbers (remember a variable is still counted as a number)
So there's one you missed!
4-v, no, as there is no equal sign.
6, no, it's just a lone number.
5g, means 5xg, but there is no equal sign-no.
So there you have it. I hope this helped you!!! ^^

What is the value of u? (pls help and no links)
Answer:
I think 44 degrees
Step-by-step explanation:
73-29=44
Answer:
44
Step-by-step explanation:
The value of u, combined with the angle directly next to it (with the measurement of 29°), is a vertical angle to the opposite given angle (73°).
Note that, by the definition of vertical angles, angles directly next and opposite of each other have the same measurement. Set the equation:
u + 29 = 73
Isolate the variable, u. Note the equal sign, what you do to one side, you do to the other. Subtract 29 from both sides:
u + 29 (-29) = 73 (-29)
u = 73 - 29
u = 44
44° is your answer for u.

Answer:
B. M - J = 6
Step-by-step explanation:
Mike won 6 more games than Jeanie
so J + 6 = M
Subtract J from both sides of the equation
J - J + 6 = M - J
Simplify
6 = M - J
or
M - J = 6

Answer: 1075 sq. ft
Step-by-step explanation:
A = length times width
First split the shape into two rectangles

Area of rec 2 = 35 times 25 = 875
200+875 = 1075 sq. ft
Assume that the assumptions and conditions for inference with a two-sample t-test are met. Test the indicated claim about the means of the two populations. State your conclusion. Researchers wanted to compare the effectiveness of a water softener used with a filtering process to that of a water softener used without filtering. Ninety locations were randomly divided into two groups of equal size. Group A locations used a water softener and the filtering process, while group B used only the water softener. At the end of three months, water samples were tested at each location for softness level. (Water softness was measured on a scale of 1 to 5, with 5 being the softest water.) The results were as follows.
Group A (water softener and filtering)
xbar1 = 2.1
s1 = 0.7
Group B ( water softener only)
xbar2 = 1.7
s2 = 0.4
Using a 5% significance level, determine whether there is a difference between the two types of treatments.
H0: μ1 - μ2 = 0
Ha: μ1 - μ2 ≠ 0
Test statistic t = 3.328, P-value = 0.0014, DF = 69.97
A. Since the P-value is less than 0.05, we accept the null hypothesis and conclude that there is no difference in the softness level achieved from the two processes.
B. Since the P-value is less than 0.05, we are unable to reject the null hypothesis; there is insufficient evidence to conclude that there is a difference in the softness level achieved by the two processes.
C. Cannot draw a conclusion from the information given.
D. Since the P-value is less than 0.05, we reject the null hypothesis and conclude that there is a difference in the softness level achieved by the two processes.
E. Since the P-value is less than 0.05, we reject the alternative hypothesis and conclude that there is no significant difference in the softness level achieved by the two processes.
Answer:
D. Since the P-value is less than 0.05, we reject the null hypothesis and conclude that there is a difference in the softness level achieved by the two processes.
Step-by-step explanation:
H0: μ1 - μ2 = 0
Ha: μ1 - μ2 ≠ 0
Test statistic t = 3.328, P-value = 0.0014, DF = 69.97
The Critical value for df = 69.97 is t ( ∝/2) (df): ±1.9945
The calculated t value falls in the critical region so H0 is rejected
As P - value is less than significance level H0 is rejected .
It is a two tailed test and the P - value is0.0014 which is less than 0.05 the significance level.
This means the softness achieved by Process A is considered to be not equal to the softness achieved by the Process-B .
Only choice D is correct.

David and Patti each decomposed 138. David wrote 1 + 1/8 + 3/8. Patti wrote 4/8+2/8+5/8.
Who Is Correct?
No downloads
No Links
No files
No bitly.
Answer:
Both are wrong.
Step-by-step explanation:
We have that:
Both decomposed the fraction [tex]\frac{13}{8}[/tex] into a sum of fractions. Whoever's decomposition sum has a value of [tex]\frac{13}{8}[/tex] is correct.
David:
[tex]1 + \frac{1}{8} + \frac{3}{8} = \frac{8}{8} + \frac{1}{8} + \frac{3}{8} = \frac{8+1+3}{8} = \frac{12}{8}[/tex]
[tex]\frac{12}{8} \neq \frac{13}{8}[/tex], which means that David is wrong.
Patti
[tex]\frac{4}{8} + \frac{2}{8} + \frac{5}{8} = \frac{4+2+5}{8} = \frac{11}{8}[/tex]
[tex]\frac{11}{8} \neq \frac{13}{8}[/tex], which means that Patti is wrong.
So the answer is that both are wrong.
