The average height of 18-year-old American women is 64.2 inches. You wonder whether the mean height of this year's female graduates from your local high school is different from the national average. You measure an SRS of 78 female graduates and find that x¯¯¯ = 63.1 inches. What are your null and alternative hypotheses? Note: Type in "mu" as the substitute for μ and "!=" for ≠.
Answer:
Step-by-step explanation:

The null and alternative hypotheses are [tex]H_o[/tex] μ= 64.2 and [tex]H_a[/tex]: μ ≠ 64.2 respectively.
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter. Using sample data, hypothesis testing is performed to examine the plausibility of a theory.
The average height of an 18-year-old American woman is 64.2 inches
Hypotheses state claims about a population parameter.
p: population proportion: population mean
σ: population standard deviation
The null hypothesis asserts that the sample size equals the claim value:
[tex]H_o[/tex] :μ= 64.2
The alternate hypothesis expresses the inverse of the null hypothesis (As per the claim):
[tex]H_a[/tex] : μ ≠ 64.2
μ = The average height of 18-year-old American women in the population.
[tex]H_o[/tex] :μ= 64.2
[tex]H_a[/tex] : μ ≠ 64.2
Thus, the null and alternative hypotheses are [tex]H_o[/tex] μ= 64.2 and [tex]H_a[/tex]: μ ≠ 64.2 respectively.

Answer these two questions I am confused. Number 17 and 18.
Answer:
Step-by-step explanation:
Question 17
y-y1 = m (x-x1 )
so basically you plug in the (x,y) to y1 and x1 place
Remeber always times it by -1
so answer would be
y-2 = -1/3 (x+4)
Question 18
Pretend its 3x+2y =8
you need to find x or y first im going to find y first
so
- 2y = -3x +8
divide by 2 to isolate y
y = -3/2x - 4
plug it back into the equation
3x + 2(-3/2x) - 4
the x will cancel
so y= -4
Then
plug in the -4 in place of y
SO the Answer is YES because y is horizontal there is -4 = there will be (-3, -4)!

Bonus question: If Susan makes$12.50 an hour for working a regular 40 hour week, and she invests one day's pay in a savings account that earns .05% interest, how much money would she have in her saving account after 1 year if she opened her account with $500? *
Answer:
Your answer would be: almost $5, but the actual amount is $4.67.
Reason being: when you divide $140 by 30, you get $4.67, and rounding to the nearest number, you get $5.
Therefore, the answer is $4.67
Step-by-step explanation:
Hi!
From what I know, the answer is: $5,503.
I got that answer by first multiplying 40 to 12.50, which was 500, then added .05% to 500, which ended up being 500.25. Then multiplied 500.25 with 12 (because there's 12 months in a year.) which was 6,003. I then subtracted 500 (because she opened it with 500) from 6,003 which was, the answer, $5,003.
Hope this helps! Sorry if its wrong, I was seriously racking my brain trying to get you this answer lol.

Find the percent increase round to the nearest percent from 13 friends to 15 friends percent increase is what percent
Answer:
15%
Step-by-step explanation:
Answer:
15%
Step-by-step explanation:
Since it is increasing from 13 to 15, the difference is 2
so you now
have to divide 2 by 13
because 13 is the original friend amount.
2 divided by 13 is equal to 0.153846153846153846153846153846
since the units are percent
it should techincally turn into
15.3846153846153846153846153846
but since you are rounding to the nearest percent
it would be 15%
Air pressure may be represented as a function of height (in meters) above the surface of the Earth, as shown below. = 0.000125 P(h) = P..e In this function, Po is the air pressure at the surface of the Earth, and his the height above the surface of the Earth, measured in meters. Which expression best represents the air pressure at an altitude of 3,000 meters above the surface of the Earth? h A. Pole 0.36 B. Po 2-3,000 C. Poe-0.36 D. 3,000 -0.00012P.
please someone help
The expression that represents the air pressure at an altitude of 3,000 meters above the surface of the Earth is P(3,000) = Po * e^(-0.375).
The expression that best represents the air pressure at an altitude of 3,000 meters above the surface of the Earth can be found by substituting the given values into the given function.
The given function is P(h) = Po * e^(-0.000125h), where Po represents the air pressure at the surface of the Earth and h represents the height above the surface of the Earth.
To find the air pressure at an altitude of 3,000 meters, we substitute h = 3,000 into the function:
P(3,000) = Po * e^(-0.000125 * 3,000)
Simplifying further:
P(3,000) = Po * e^(-0.375)
Thus, the expression that represents the air pressure at an altitude of 3,000 meters above the surface of the Earth is P(3,000) = Po * e^(-0.375).

The angle measures of a triangle are 2y + 3 degrees, 9y – 7 degrees, and 7y + 4 degrees. Which of the following is not one of the angle measures of the triangle?
Answer:
55
Step-by-step explanation:
The measures of the angles are 23, 83, and 74 degrees. 97 degrees is not the measure one of the angle measures of the triangle option (B) is correct.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
It is given that:
The angle measures of a triangle are 2y + 3 degrees, 9y – 7 degrees, and 7y + 4 degrees.
As we know,
The sum of the interior angle of the triangle is 180 degrees
2y + 3 + 9y - 7 + 7y + 4 = 180
18y = 180
y = 10
2y + 3 = 2(10) + 3 = 23 degres
9y - 7 = 9(10) - 7 = 83 degrees
7y + 4 = 7(10) + 4 = 74 degrees
Thus, the measures of the angles are 23, 83, and 74 degrees. 97 degrees is not the measure one of the angle measures of the triangle option (B) is correct.

[tex]\boxed {x = -\frac{8}{9}}[/tex]
Step-by-step explanation:
Solve for the value of [tex]w[/tex]:
[tex]3(3w - 4) = -20[/tex]
-Use Distributive Property:
[tex]3(3w - 4) = -20[/tex]
[tex]9w - 12= -20[/tex]
-Add both sides by [tex]12[/tex]:
[tex]9w - 12 + 12 = -20 + 12[/tex]
[tex]9w = -8[/tex]
-Divide both sides by [tex]9[/tex]:
[tex]\frac{9w}{9} = \frac{-8}{9}[/tex]
[tex]\boxed {x = -\frac{8}{9}}[/tex]
Therefore, the value of [tex]w[/tex] is [tex]-\frac{8}{9}[/tex].

solve system of equations algebraically
Answer:
y=-2 x=-2
Step-by-step explanation:
y=-x-4
y=x
you can plug y in for x in the first equation by using substitution
y=-y-4
and then you solve for y
2y=-4
y=-2
so y equals -2. Since y=x, x also equals -2. Therefore
y=-2 x=-2
