Answer:
The median score was greater for science, but the range was greater for math.
Step-by-step explanation: I think I don’t now.
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)
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

PLEASE HURRY! this is financial algebra
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

f(x) = x^2. What is g(x)?
Answer:
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?
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
