A doctor has invented a relaxation method that he
thinks will relieve anxiety and help students score
higher on exams. He wants to test the method on a
group of statistics students to see if it improves their
scores on the final exam. All of the students have
volunteered to participate.
What is the response variable for the experiment?

Answers

Answer 1

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

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

Answers

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​

Answers

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).

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.​

Answers

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
