Answer:
Null hypothesis is; H0: μ = 174.1 cm
Alternative hypothesis is; Ha: μ ≠ 174.1 cm
No, it's not possible to conclude that there is enough evidence to support the claim.
Step-by-step explanation:
We are told that the A formal hypothesis test is to be conducted using the claim that the mean height of men is equal to 174.1 cm.
This means that the null hypothesis is;
H0: μ = 174.1 cm
Now, the alternative hypothesis would state the opposite of the null hypothesis. Thus, alternative hypothesis is;
Ha: μ ≠ 174.1 cm
The possible conclusions to make is that we can either reject the null hypothesis or fail to reject the null hypothesis.
Since we don't have value of test statistic and degree of significance, we cannot conclude that "there is sufficient evidence to support the claim that the mean height of men is equal to 174.1 cm"
The chair of the operations management department at Quality University wants to construct a p-chart for determining whether the four faculty teaching the basic P/OM course are in control with regard to the number of students who fail the course. Accordingly, he sampled 100 final grades from last year for each instructor, with the following results: Instructor Number of Failures Prof. A 13 Prof. B 0 Prof. C 11 Prof. D 16 What is the estimate of the standard deviation of the sampling distribution for an instructor's sample proportion of failures?
Answer:
0.03
Step-by-step explanation:
Given the following :
Instructor __no of failure __prop (failure /100)
A ________ 13__________0.13
B ________0___________0
C________11___________0.11
D________16__________0.16
Prof. B adds no proportion to the data and hence excluded in the estimation.
Mean(m) = 0.13 + 0.11 + 0.16) / 3
= 0.4 / 3
= 0.1333
Standard deviation :
Σ(X - m)² / N - 1
Σ(0.13 - 0.1333)² + (0.11 × 0.1333)² + ( 0.16 - 0.1333)² = 0.0012668689
= 0.0012668689 / 2
= 0.00063343445
√0.00063343445
= 0.0251681
= 0.03 To 2 decimal places

Answer:
(-2, 3 )
(-1, 2[tex]\frac{1}{2}[/tex])
(0, 2)
(1, 1[tex]\frac{1}{2}[/tex])
(2, 1)
Step-by-step explanation:
You just simply substitue the values given into the equation, and the answer worked out will be the value of y.
a = - [tex]\frac{1}{2}[/tex] × -2 + 2 = 1 + 2 = 3
b = - [tex]\frac{1}{2}[/tex] × -1 + 2 = [tex]\frac{1}{2}[/tex] + 2 = 2[tex]\frac{1}{2}[/tex]
c = -[tex]\frac{1}{2}[/tex] × 0 + 2 = 0 + 2 = 2
d = -[tex]\frac{1}{2}[/tex] × 1+ 2 = -[tex]\frac{1}{2}[/tex] + 2 = 1[tex]\frac{1}{2}[/tex]
e = -[tex]\frac{1}{2}[/tex] × 2+ 2 = -1 +2 = 1

Does anyone know this one?
Answer:
C
Step-by-step explanation:
For the lines to be parallel, then the 2 given angles are alternate and congruent, thus
15x - 46 = 9x + 8 ( subtract 9x from both sides )
6x - 46 = 8 ( add 46 to both sides )
6x = 54 ( divide both sides by 6 )
x = 9 → C

Step-by-step explanation:
A football team is known to run 30% of its plays to the left and 70% to the right. A linebacker on an opposing team notices that, when plays go to the right, the right guard shifts his stance most of the time (80%) and that he uses a balanced stance the remainder of the time. When plays go to the left, the guard takes a balanced stance 90% of the time and the shift stance the remaining 10%. On a particular play, the linebacker notes that the guard takes a balanced stance. (a) What is the probability that the play will go to the left
Answer: 0.6585
Step-by-step explanation:
Given the following :
Proportion of play to the left = 30% = 0.3
Proportion of play to the right = 70% = 0.7
Play to the right:
Shift stance = 80% = 0.8
Balanced stance = (1 - 0.8) = 0.2
Play to the right with balanced stance = (0.2 × 0.7) = 0.14
Play to the right with shifted stance = (0.8 × 0.7) = 0.56
Play to the left:
Balanced stance = 90% = 0.9
Shifted stance = (1 - 0.9) = 0.1
Play to the left with balanced stance = (0.9 × 0.3) = 0.27
Play to the left with shifted stance = (0.9 × 0.3) = 0.03
Probability that play will go to the left if the linebacker takes a balanced stance :
Overall proportion of play with balanced stance :
Balanced with play to the right + balanced with play to the left = (0.14 + 0.27) = 0.41
Balanced play to the left = 0.27
= (balanced play to the left / total proportion of balanced stance)
= 0.27 / 0.41
= 0.6585365
= 0.6585

Jaiden earned $84 last week. Peter earned only $12. Jaiden’s earnings are how many times greater than Peter’s? Choose the answer that has the correct equation AND the correct solution to the equation.
12x = 84; x = 7 times more
12 + x = 84; x = 72 times more
84x = 12; x = 7 times more
12x = 84; x = 9 times more

HELP ME PLEASEEE!!!!!!! I am stuck
Answer:
X = 62
Step-by-step explanation:
The inside of a triangle is always equal to 180º therefore, you need to add everything up to equal 180. It should look like
(x + 1) + 55 + x = 180
Now you just solve.
Since there are 2 x's you can combine the like terms making them equal 2x
Now the equation should look like 2x + 1 + 55 = 180
Simplify the other like terms: 2x + 56 = 180
Now you want to get x by itself so you subtract 56 from both sides:
2x + 56 = 180
-56 -56
------------------------
2x = 124
Now to finish getting x by itself, divide both sides by 2.
2x = 124
----- ------
2 2
x = 62
FINALLY you plug in x to see if it worked.
(62 + 1) + 55 + 62 = 180
if a number is an integer, then it is odd
Answer:
The integers are, -4, -3, -2, -1, 0, 1, 2, 3, 4, ... -- all the whole numbers and their opposites (the positive whole numbers, the negative whole numbers, and zero). For example, -5 is an integer but not a whole number or a natural number. An odd number is an integer when divided by two, either leaves a remainder or the result is a fraction. One is the first odd positive number but it does not leave a remainder 1. Some examples of odd numbers are 1, 3, 5, 7, 9, and 11. ... Since odd numbers are integers, negative numbers can be odd.
5 – 7k = -40k + 1) – 3
Do we have to distribute?
Answer:
Nope because, wait did you forget a parenthesis to the left of -40?
But if there is no parenthesis, you don't have to distribute it.
If there are parenthesizes however, you would need to distribute it.

If Ethan takes out a $5,000 loan to buy a motorcycle and his payments are $168.45 a month for 36 months, how much money will he pay in interest over the life of the loan?
Answer:
$1064.20
Step-by-step explanation:
36 payments of $168.45 have a total of $6064.20. The excess over the loan amount of $5000 is the interest paid:
$6064.20 -5000 = $1064.20 . . . . interest paid

f(x) = 14 – 0.5x f(30)=
Answer: f(30) = -1
You would substitute every X with 30
Answer:
-1
Step-by-step explanation:
First, plug in 30 to your equation (f(x) = 14 - 0.5(30)
0.5 • 30 is 15, so subtract 15 from 14 and you get -1

HELP ME QUICK To get to the dance competition finals, a dancer must average at least 8.5 points on their 4 preliminary dances. The scores for Jodi’s first 3 dances were: 8.9 points, 7.1 points and 9.2 points.
What is the lowest score that Jodi can get on the last dance and still make the finals?
Show all your work AND justify your steps. You will not receive credit unless you justify the steps. Make sure to answer the question. Note: Judges scores range from 0 to 10 and include the tenths place (like 7.5).
Answer:
[tex]x = 8.8[/tex]
Step-by-step explanation:
Given
[tex]Average = 8.5[/tex]
[tex]Scores= 8.9, 7.1, 9.2[/tex]
Required
Determine the least score in the 4th dance
Represent the 4th score using x
Average is calculated as follows:
[tex]Average = \frac{\sum x}{n}[/tex]
This gives:
[tex]8.5 = \frac{8.9 + 7.1 + 9.2 + x}{4}[/tex]
[tex]8.5 = \frac{25.2 + x}{4}[/tex]
Multiply through by 4
[tex]4 * 8.5 = 25.2 + x[/tex]
[tex]34= 25.2 + x[/tex]
[tex]x = 34 - 25.2[/tex]
[tex]x = 8.8[/tex]
Hence, the least score in the 4th dance is 8.8
