Answer:
a. Whether the student attended a workshop. Neither
b. Number of workshops attended. Explanatory variable
c. Whether the student passes the course. Response variable
Step-by-step explanation:
In a given experiment, the response variable addresses the core of the question that was asked. In the experiment above, we are trying to determine the passing rate. That is the response variable. The explanatory variable provides an explanation for the response.
The number of workshops attended by the students would provide an explanation of their passing rates. Whether the student attended a workshop is not a consideration in the experiment, because it is believed that they would attend the workshop.
6/7x - 8 = 7
i need to solve for the missing variable
Answer:
the answer would be 17.500
Answer:
x = 35/2
Step-by-step explanation:
add: (6/7)x = 8 + 7
(6/7)x = 15
multiply by the reciprocal
x = 15(7/6)
Simplify
x = 5(7/2)
multiply:
x = 35/2
Check:
(6/7)(35/2) -8 = 7
15 -8 = 7

Cost of bowling if it is $3 per game and $5 for shoes. Find the linear equation.
Answer:
y=3x+5
Step-by-step explanation:
Depending on how many games he has played that number where the x is. So let’s say he plays two games so what you’re going to do is plug the two in for the X so then it would be 2×3 which is 6 then you would do 6+5 because you still have the 5 left and it says to add.
That should be right and follow me if this helps.

A fruit salad recipe calls for 3/4 pound of apples and 2/5 pound of dates. What is the least common denominator of the fractions?
(1 Point)
Answer:
20
Step-by-step explanation:
because 4x5 equals 20
estimate the product choose the method 27 * 42
Answer:
About 1200
Step-by-step explanation:
I would round them to the nearest 10 so 27 would become 30 and 42 would be 40.
Then you would multiply to get the answer of about 1200.
Hope that helps and have a great day!
Change the given equation into slope-intercept form:
1. - 2 + y = -x
rearrange the equation, so it would be y = -x+2

A 12-ounce sports drink costs 0.96 and a 16-ounce sports drink costs $1.12. Which size is the best
buy? How much cheaper is it? Ratios
Answer:
It is better to buy the 16-ounce drink and it is 0.01 cent cheaper
Step-by-step explanation:
We have to find out how much each sports drinks cost per ounce.
0.96 ÷ 12 = 0.08 per ounce
1.12 ÷ 16 = 0.07 per ounce
It is better to buy the 16-ounce drink and it is 0.01 cent cheaper
Hope this Helps! :)

13 - 10 = 33 & 13The proportion, x = 23.Step-by-step explanation:
13 (i.e 100%) - 10 (i.e 77%) = 3 (i.e 23%)difference is 3 & original amount is 13The proportion, x = 23%Which arrangement shows 27/5, 5.36, 5 3/5, 33/6 in order from least to greatest?
Answer:
5.36 < 27/5 < 33/6 < 5 3/5 or 5.36, 27/5, 33/6, 5 3/5

Three times a number increased by one is between negative eight and seven find all the numbers.
All the numbers that makes the statement true are given by?
Please hurry this is on my exam
This is about absolute value inequalities.
The set of possible values of x that make the statement true are; x = {-2, -1, 0, 1}
Let the number in the question be x.We are told that when it is multiplied by 3 and 1 added to it, it is between - 8 and 7. This means it is greater than -8 but less than 7.
Thus;
3x + 1 > -8 - - - (eq 1)
3x + 1 < 7 - - - (eq 2)
Let's find range of x from eq 1;3x + 1 > -8
Subtract 1 from both sides to get;
3x > -9
x > -9/3
x > -3
Similarly, let's find the range of x from eq 2;3x + 1 < 7
Subtract 1 from both sides to get;
3x < 7 - 1
3x < 6
x < 6/3
x < 2
Thus, we can write that;
-3 < x < 2
Thus, the set of possible values of x are; x = {-2, -1, 0, 1}

When you were playing the integer game the first two cards that were selected were -8 and -10. What is the value in your hand?
Write an equation to justify your answer
what is the distance of the sum from -8
Answer:
The value in your hand is -18
let the value be x, then the equation is:
x = -8 + (-10)
x = - 8 - 10
x = - 10
the distance of the sum from -8 is the distance between -8 & -10, i.e -8 - (-10) = 2.

x/2.4+39=239
show work
Answer: x = 480
Steps: x/2.4 + 39 = 239
Subtract 39 from both sides: x/2.4 + 39 - 39 = 239 - 39
Simplify: x/2.4 = 200
Multiply both sides by 2.4: x/2.4 × 2.4 = 200 × 2.4
Simplify: x = 480

Evaluate:
-77 + (-46)
-77 + (-46 )
- 77 - 46 (+ × - = - )
-123
Answer:
-123
Step-by-step explanation:
This is the answer because:
1) First, multiply the negative sign with the positive sign.
Negative x Positive = Negative
Equation: -77 - 46
2) Now, multiply the negative sign with the negative sign.
Negative x Negative = Positive
Equation: 77 + 46 = 123
3) Finally, add the greater number's sign (-77) in front of the number.
-123
