Answer:
Exam score
Step-by-step explanation:
The response variable also known as the d pendent variable, is simply the variable we intend to measure based in a set of variables (independent variables or explanatory variables) which might cause it to change. For instance, the scenario above aims to look into how a certain relaxation method will affect the exam score, here, the variable we intend to measure is the response variable which is exam score. The exam score is affected by the impact the relaxation method has on the student, hence, the relaxation method is the independent or explanatory variable.

Answer:
p = 5/12
Step-by-step explanation:
-14+6p = -9-6p
Add 6p to each side
-14+6p+6p = -9-6p+6p
-14 +12p = -9
Add 14 to each side
-14+12p = -9 +14
12p =5
Divide by 12
12p/12 = 5/12
p =5/12

Write an equation for..
“The child’s tickets cost $4 each and the adult’s ticket cost $8 each. Write an equation that would represent the total cost, T, of purchasing a child’s tickets, c, and an adult’s tickets, a.”
Answer:
cxa=t cause you are mulltipling to find the total cost
Answer:
Step-by-step explanation:
A child´s ticket costs $4 and adults ticket costs $8. If we want one of each we need to add both numbers together, 4 plus 8 equals 12. The total cost of a child ticket and an adult ticket is $12.
The questions asked to write an equation; the equation would be:
C+A=T it could also be written as A+C=T, T=A+C or T=C+A.

Answer:
x = 4
Step-by-step explanation:
Here, given that the two triangles are similar, we want to find the value of x
Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal
Thus, we have it that;
ED/EF = XY/YZ
5/2x-1 = 10/14
14(5) = 10(2x-1)
70 = 20x -10
70 + 10 = 20x
20x = 80
x = 80/20
x = 4

Answer: 37, [tex]\frac{x+2}{7}[/tex]
Step-by-step explanation:
Given
[tex]f(x)=7x-2\\g(x)=x^2+1\\h(x)=3x[/tex]
now,
[tex]g(h(x))=(3x)^2+1\\g(h(x))=9x^2+1[/tex]
for x=2
[tex]g(h(2))=9\cdot (2)^2+1\\g(h(2))=36+1\\g(h(2))=37[/tex]
Inverse of [tex]f(x)[/tex] is given by
[tex]y=7x-2\\x=\dfrac{y+2}{7}\\\\f^{-1}(x)=\dfrac{x+2}{7}[/tex]

Answer: x = 3
Step-by-step explanation:
-10x - 2y = -30
3x + 2y =9
use elimination method...
-2y and 2y = 0
-10x = - 30
3x = 9
add together...

A college professor hands out a list of 10 questions, 5 of which will appear on the final exam for the course. One of the students taking the course is pressed for time and can prepare for MATH 270 Assignment 2 W. Li 2 only 7 of the 10 questions on the list. Suppose the professor chooses the 5 questions at random from the 10. a) What is the probability that the student will be prepared for all 5 questions that appear on the final examination
Answer:
21 / 252
Step-by-step explanation:
Recall : nCr = n! ÷ (n-r)!r!
The total possible outcome ; 5 questions out of 10
10C5 = 10! ÷ 5!5! = (10*9*8*7*6)÷(5*4*3*2*1) = 252
Required outcome :
All 5 questions set being from the 7 questions covered and 0 from the 3 left uncovered
7C5 * 3C0
7C5 = 7! ÷ 2!5! = (7*6) ÷ (2*1) = 21
3C0 = 3! ÷ 3!0! = 1
Probability = required outcome / Total possible outcomes
P(All 5 questions prepared for appears) :
[7C5 * 3C0] ÷ 10C5
(21 * 1) / 252
= 21 / 252

Leah rolls two 6-sided number cubes. What is the probability that she rolls a sum equal to 10?
A. 1/11
B. 10/36, or 5/16
C. 2/36, or 1/18
D. 3/36, or 1/12
Answer:
D. 3/36, or 1/12
Step-by-step explanation:
The probability of rolling a sum equal to 10 on two six-sided number cubes is 3/36.
This is because of the 36 total outcomes, only 3 have a sum of 10.
In other words, the probability of rolling a sum equal to 10 is 3 in 36, or 3 out of 36 (3/36).

Best answer is getting brainiest
Answer:
17.8
Step-by-step explanation:
We can find this because we know that to make a cube, we need to do [tex]c*c*c[/tex] or [tex]c^3[/tex]. With this, we can simplify our equation (by taking the root of both sides) to [tex]c=\sqrt[3]{5639.752}[/tex] or 17.8.
c) Solve for x given the perimeter of the trapezoid is 277 m.

Could anyone help me find the surface area of this? I got 340 and I don't think it's right.
Answer: I got 200
Step-by-step explanation: 14+14+5+5=38*2=76 Thats the front and back and then The sides are 6+6+5+5=22*2=44 then the top and bottom are 14 +14+6+6=40*2=80 then add that all up and 44+80+76=200 (Sorry if its a bit confusing to understand)

1200 bricks each of 0.075m3 volume are required to construct a wall of length 25m and height 9m. Find the breadth of the wall.
Here's the solution,
Volume of wall :
=》total bricks × volume of each brick
=》1200 × 0.075 m³
=》90 m³
volume of wall :
=》lenght × width × height
=》25 × 9 × width
=》225 × width
now, by equating the volumes, we get
( since they are volume of same wall )
=》225 × width = 90
=》width = 90 ÷ 225
=》width of wall = 0.4 m

Answer:
For #9 it can be 4,6, or 7
#10 is angle 3
#11 is 134
#12 is 49
Step-by-step explanation:
#9 just look at the picture given and see which one is opposite from it
#10 look at which one is beside it but that the ’half‘ circles are facing each other
#11 and #12 subtract the angles they give you and see if they are next to each other and if they are that subtract the number they give you by 180-the degrees of a line

There are four cards numbered 1 through 4. The number 2 card is chosen randomly and not replaced. Find the probability of choosing a second card that is the number 3.
Answer:
1/3
Step-by-step explanation:
since number 2 card was not replaced, we have;
probability of picking a second card, 3;
let S be number of sample space
n(S)= 4
n(3)= 1
Pr(3/2)= 1/3
(because since one was already chosen and n, the sample space would reduce)
