Answer:
1. f = 9/a +7
2. x = (y -5)/3
3. x = 3/(y +2)
4. l = (P +9)/4
Step-by-step explanation:
I find it convenient to use the fact that a=b/c can be rewritten as c=b/a:
[tex]a=\dfrac{b}{c}\qquad\text{given}\\\\ac=b\qquad\text{multiply by $c$}\\\\c=\dfrac{b}{a}\qquad\text{divide by $a$, effectively swapping $a$ and $c$}[/tex]
__
1. f - 7 = 9/a . . . . use the above shortcut
f = 9/a +7 . . . . add 7
__
2. y -5 = 3x . . . . . subtract 5
x = (y -5)/3 . . . . divide by 3
__
3. y +2 = 3/x . . . . add 2
x = 3/(y +2) . . . . use the above shortcut
__
4. P +9 = 4l . . . . add 9
l = (P +9)/4 . . . divide by 4

Suppose a test of significance desires to see if there is a difference in mean SSHA scores between men and women. Which is the appropriate alternative hypothesis?
a. The population mean for women equals the population mean for men.
b. The population mean for women does not equal the population mean for men.
c. The population mean for women is greater than the population mean for men.
d. The population mean for women is less than the population mean for men.
Answers
Answer:
The correct option is b.
Step-by-step explanation:
A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.
It is a hypothesis of no difference.
It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.
For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.
Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.
The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.
It is also known as the research hypothesis and is denoted by Hₐ.
The research statement is:
"If there is a difference in mean SSHA scores between men and women."
Then the appropriate alternative hypothesis will be:
Hₐ: The population mean for women does not equal the population mean for men, i.e. μ₁ ≠ μ₂
The correct option is b.

3. A ladder leaning against a wall
makes an angle of 68° with the
ground. If the foot of the ladder is 4
feet from the wall, how high on the
wall is the ladder, to the nearest
tenth of a foot?
Answers
Answer:
tangent 68° = opposite / adjacent
opposite (wall height) = tan (68) * 4 feet
opposite (wall height) = 2.4751 * 4 feet
opposite (wall height) = 9.9004 feet or
9.9 feet (to the nearest tenth of a foot).

At the beginning of every gym class, Mr. Gordon leads the class in a warm-up. In today’s warm-up, the class does jumping jacks for 3 minute. Erin does 54 jumping jacks in that time. Mr. Gordon says the class will do jumping jacks 4 minutes tomorrow. If Erin does jumping jacks at the same rate tomorrow, how many will she she do.
Answers
Answer:
Erin will do 72 jumping jacks.
Step-by-step explanation:
We divide 54 by 3 to get Erin's per minute ratio
She gets 18 jumping jacks per minute
We then add that to 54 to get her rate if she did for 4 minutes instead
The answer is 72
hope this helped!
Erin will do 72 jumping jacks in 4 minutes.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, Erin does 54 jumping jacks in 3 minutes.
Therefore, mathematically:
3 minutes = 54 jumping jacks
1 minute = 18 jumping jacks
4 minutes = 72 jumping jacks
Hence, Erin will do 72 jumping jacks in 4 minutes.

Is it possible to improve your grade from a "d" to a "b"?
Answers
Answer: Of course it is possible if you try your hardest and study
Answer:
Depends
Step-by-step explanation:
Hello! This problem really depends on where you are in the grading period and how many grades are entered in relation to your grade. If you have a D but only have 2 grades then getting a B in the class should be relatively easy. However, if you have a D in a class that you have 15 graded assignments in it will be much harder to raise your grade to a B. Best thing to do is work at this early and try not to let your grade dip throughout the grading semester.
