The answer to whether Dr. Reyes can make a causal inference from the study is;
No, she can't make a casual inference from the study because she met only one of the three criteria's for causality.
To answer this question, we need to know the conditions for causality in statistics research because causality gives the relationships such that a change in one variable would have to result in a change in another variable.
Now, the three conditions are;
1) Covariation; This condition means that the causal variable must have to vary with with the variable it is assumed to cause in a systematic manner.
2) Temporal precedence; Thus condition simply means that cause must precede effect. In summary it denotes that the variable that has the causal effect must come before the effect that it is meant to cause.
3) Control for extraneous variables; This condition means that results of an experiment or research must not be due to factors outside of the experiment/research
Now, in our question, he fulfilled the covariation condition because the
result of the research is tied to the responses from the sample students.
However, she did not fulfill the temporal precedence because the cause of
their moods did not precede the effects in his research.
Also, she did not fulfill the condition of control of extraneous variables
because other factors outside of the research itself may have affected their
moods.

Answer:
Oh ok
Step-by-step explanation:
An expression is defined as a set of numbers, variables, and mathematical operations. The given statement "Double the product of eight and a number" in the form of an expression can be written as 16x.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Let the unknown number be represented by x.
The product means multiplication, therefore, we need to double or multiply the product or multiplication of eight and x.
Thus, The given statement in the form of an expression can be written as,
2(8 × x)
= 2(8x)
= 16x
Hence, the given statement "Double the product of eight and a number" in the form of an expression can be written as 16x.

prove that 5^(2n - 1) is divisible by 8
Answer:
Step-by-step explanation:
Prove that 52n − 1 is divisible by 8 for all n ∈ N.
Solution
To prove by induction, we must
1. Show it is true for n = 1
2. Assume true for n and prove it is true for n + 1.
Let P(n) be the statement 52n − 1 is divisible by 8.
When n = 1, 52 − 1 = 24, which is divisible by 8.
This proves P(1).
Suppose that P(n) is true, i.e., 52n − 1 is divisible by 8.
Then 52(n+1) − 1 = 52
· 5
2n − 1 = 52
(52n − 1) + (52 − 1).
Note that 52n −1 is divisible by 8 using P(n) and also 52 −1 = 24 is divisible
by 8. Thus we have proved that P(n + 1) is true.
We conclude that P(n) is true for all n ∈ N.
Use compatible numbers to estimate the correct quotient.

After watching Donald Duck in Mathmagic Land, please type out three things that you learned from the video. Did you like the video? Why or why not? Please answer all parts to the question
Answer:
Hope this helps
Step-by-step explanation:
Mathmagic Land had taught me more about math that I never knew before. I learned that everything can be involved with math. It all starts at the Pythagoreans which were the Greek. An example of how math is used today, is by playing billiards.
In billiards, you have to have a good technique of how your going to hit the ball, (good angles,) and you have to have a precise calculation of the angle your going to hit it at.I also learned when you cut shapes like a sphere, it just makes more and more shapes.
This is what I learned watching the Mathmagic Land Video.
Yes, Donald Duck in Mathmagic Land taught me alot of things I did not know before.

SHOW ALL WORK : A metal bar has a length of 5.0 cm, a width of 3.0 cm, and a height of 1.0 cm. What volume of water, measured in deciliters, would this bar displace?
9514 1404 393
Answer:
0.15 dL
Step-by-step explanation:
The volume of the bar is ...
V = LWH
V = (5 cm)(3 cm)(1 cm) = 15 cm³
1 dL = 100 cm³, so this volume is ...
(15 cm³)(1 dL)/(100 cm³) = 0.15 dL
The bar will displace 0.15 deciliters.

-22
m=⅓
m=-3
m=3
m=-⅓
Answer: Slope of the line formed by the data is -3.
m=-3 for y=mx+b.
Step-by-step explanation: The slope is the change in y (the rise) divided by the change in x (the run) between two points on the line. I'll pick 2 points: (-4,17) and (9,-22). Any two points will work, if it is a straight line. For these points, y, the rise, changes from 17 to -22, for a net change of (-22 - 17) = -39 for y. x, the run, goes from -4 to 9, for a change in x of (9 - (-4)) = 13.
The rise(y) over the run(x) for these points is thus (-39/13) = -3
The slope is -3

Which of the following rational number between 3/7 and 7/8 ?
13/56
19/56
27/56
53/56
Answer:
Step-by-step explanation:
There are two ways to do this. You could use your calculator to find out the decimal numbers that are equivalent to the two given fractions. Then check which one of the givens falls between these two numbers. I wouldn't do it that way -- not when you are told that the answer has 56 as the denominator. So ...
The best way to do it is to change the two givens so that they have a denominator of 56
3/7 = 3*8/7*8 = 24 / 56
7*7 / 7*8 = 49 / 46
So you need a number that is between 49 and 24
There is only one 27 / 56

A cookie recipe calls for 2 eggs and makes 3 dozen cookies. How many dozens of cookies could you make with a dozen eggs
Answer: 18 dozen cookies.
Step-by-step explanation: If 2 eggs make 3 dozen cookies and you have a dozen eggs divide 12/2 = 6. Then multiply 6*3 = 18.
Answer:
18 dozen cookies
Step-by-step explanation:
2 eggs makes 36 cookies
That means 2x=36
x=18
Now plug that into the equation.
12(18)=216
216 is how many cookies
take that number and divide by 12 (for a dozen)
A cricket bat is bought for $400. Later, it is sold with a loss of 15%. How much is the cricket bat sold for? =
After selling the cricket bat, how much money has been lost? Give your answer to two decimal places because it is a currency.=
Answer:
$340.00
Step-by-step explanation:
What I like to do first is find 10% of the number.
So 10% of 400 would be $40.
Then find half (5%) of the 10% ($40), which would be $20.
Add the $40 + $20 to get $60.
Then take $400 and subtract $60,
which gives you $340.00

what is the slope of a line b perpendicular to line a with equation y=7x-9
Answer:
The slope of line b would be -1/7.
Step-by-step explanation:
This happens because if you have the slope of any line and are trying to find the perpendicular line to said line, the slope of the perpendicular line will always be the opposite reciprocal of the original slope.
Then, all you need to do is find some points and graph the lines.
