The median score was greater for science, but the range was greater for math.

Step-by-step explanation: I think I don’t now.

Answer 2

The statement "The median score was greater for math, but the variability was greater for science" is true

What is Statistics?

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Calculate the mean absolute deviation (MAD) for both sets of scores. The MAD measures the average distance of each score from the mean of the data set.

For the math scores, the mean is:

(72 + 92 + 88 + 67 + 54 + 58 + 64 + 76 + 65 + 72) / 10 = 70.8

To calculate the MAD for the math scores, we need to find the absolute deviation of each score from the mean.

The sum of these absolute deviations is:

1.2 + 21.2 + 17.2 + 3.8 + 16.8 + 12.8 + 6.8 + 5.2 + 5.8 + 1.2 = 91

To calculate the MAD for the science scores, we need to find the absolute deviation of each score from the mean, and then calculate the average of these absolute deviations.

The sum of these absolute deviations is:

10.4 + 4.4 + 17.6 + 15.4 + 19.6 + 5.6 + 1.4 + 4.4 + 10.4 + 13.6 = 103.4

The MAD for the science scores is:

103.4 / 10 = 10.34

Therefore, the statement "The median score was greater for math, but the variability was greater for science" is true

if f(x-3)=7x+4 for all values of X what is the value of f(-7)

Answers

Answer:

-66

Step-by-step explanation:

We have the expression f(x-3) = 7x + 4, in which for x the value is -7.

To solve first substitute x next to f(x).

f((-7) - 3) = 7x + 4

(-7) - 3

f(-10) = 7x + 4

Now that we know x is equal to -10, you may substitute to the actual equation.

f(-10) = 7(-10) + 4

f(-10) = -70 + 4

f(-10) = -66

9514 1404 393

Answer:

  -24

Step-by-step explanation:

We want to evaluate the function when ...

  x -3 = -7

  x = -4 . . . . . add 3

Then, ...

  f(-7) = f(-4-3) = 7(-4) +4

  f(-7) = -24

__

Alternatively, we can rewrite the function to be f(x).

  f(x) = f((x+3) -3) = 7(x +3) +4

  f(x) = 7x +25

Now, f(-7) is ...

  f(-7) = 7(-7) +25 = -49 +25

  f(-7) = -24

Answers

Answer:

6 years

Step-by-step explanation:

Simple interest= P.R.T

I = $1300

P = 18000 deposit

Rate = 1.19%

T = ?

Putting into the formula we have

1300 = 18000x1.19/100xT

1300 = 18000x0.0119xT

1300 = 214.2T

Divide through to get T

T = 1300/214.2

= 6.069

So when we approximate T = 6 years

It would take 6 years to make $1300 in interest

D. g(x) = (1/4 x)^2

Step-by-step explanation:

We have to choose a solution in which the point (4, 1) works.

A) g(x) = 1/4(x^2) = 1/4(4^2) = 1/4(16) = 4 ≠ 1

B) g(x) = (1/2 x)^2 = (1/2 * 4)^2 = 2^2 = 4 ≠ 1

C) g(x) = 4(x^2) = 4(4^2) = 4(16) = 64 ≠ 1

D) g(x) = (1/4 x)^2 = (1/4 * 4)^2 = 1^2 = 1

- There are 130 people in a sport centre,
76 people use the gym,
60 people use the swimming pool,
32 people use the track,
23 people use the gym and the pool.
8 people use the pool and the track
20 people use the gym and the track,
6 people use all three facilities,
A person is selected at random
What is the probability that the person uses exactly one of the facilities?

Answers

Answer:

0.6462 = 64.62% probability that the person uses exactly one of the facilities

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

20 people use the gym and the track and 6 people use all three facilities

So 20-6 = 14 use exactly the gym and the track and 6 use all three.

8 people use the pool and the track

So 8 - 6 = 2 use exactly the pool and the track.

23 people use the gym and the pool.

So 23 - 6 = 17 use exactly the gym and the pool.

32 people use the track

So 32 - (6 + 14 + 2) = 10 use only the track.

60 people use the swimming pool

So 60 - (6 + 2 + 17) = 35 use only the pool.

76 people use the gym

So 76 - (6 + 14 + 17) = 39 use only the gym

What is the probability that the person uses exactly one of the facilities?

Out of 130, 39 + 35 + 10 = 84 use exactly one of the facilities.

84/130 = 0.6462

0.6462 = 64.62% probability that the person uses exactly one of the facilities

Answer:

1) x=8, y=138

2) x=110

Step-by-step explanation:

Answer:

1. x = 8, y =138

2. x = 110

Step-by-step explanation:

First we will need to find the value of x.

Since, I feel like being a kindergartener I'll do it the long way.

(5*2+2)+(6*2)

12+12

24

That wouldn't work

(5*8+2)=(6*8)

42+48=90

Therefore x = 8

Since we know 42 would be 42 degrees and it is a straight angle for both 5x+2 and y.

We would subtract 180-42=138.

Therefore, y = 138

2 would be simple. All we need to do is add 80+30=110 then subtract it by 180

180-110=70. Since x and the 70 degrees equal 180 degrees.

180-70=110

Therefore, your answer would be x= 110
