Answer:
The correct statements are b, c and e.
Step-by-step explanation:
Consider the dot plot for Noah and Jada's score in the trivia game.
From the dot plot it is quite clear that the data form a bell-shaped curved or a normal curve.
For the normal distribution:
Mean = Median = Mode
Noah's mean score = 5
Jada's mean score = 3
The standard deviation of a data set is the measure of dispersion of the observations of that data set from their mean.
On closely studying the graphs we can see that the Noah and Jada's scores are almost at a same distance from the mean, i.e. the spread of Noah's score is same as the spread of Jada's score.
So, the correct statements are:
b. The standard deviation of Noah's scores is equal to the standard deviation of Jada's scores.
c. The mean of Noah's scores is greater than the mean of Jada's scores.
e. Using only Noah's scores, the mean is equal to the median
Answer:
5 boxes
Step-by-step explanation: There are 20 students, and the teacher needs 5 boxes for the entire class of 20 students. It's a trick question. The answer is 5 I think. If not, the answer is 4 because 20/5=4
Answer:
See below in bold.
Step-by-step explanation:
(A) 20 -4x=12 -x+8-3x
-4x + x + 3x = 12 + 8 - 20
0 = 0 This is an Identity.
Infinite solutions.
B). 5x+4x-3=24+8x
9x - 8x = 24 + 3
x = 27. One solution.
C. 5x+6=2x+6+3x-15
5x - 2x - 3x = -15 + 6 - 6
0 = -15
No solution.
Answer:
(1) 13.0 years
(2) {-1728, 1728}
Step-by-step explanation:
(1)
Compound annually:
= A
(47000) = 79200
=
ln() = ln()
ln and e cancel out.
(0.04)(t) = ln()
t =
t = 13.0 years
(2)
Substitute y with -4x.
Solve for x.
x = {-3, 3}
Plug in x values into any equation to find y.
y = -4(-3) and y = -4(3)
y = {-12, 12}
= = -1728
= = 1728
Answer:
1. x= 4
2. a= 5
3. k= 1
4. w= 4
5. p= 3.5
6. y= -11

sorry if there's any incorrect lol.
If your actually looking for an explanation just ask.
good luck and boom roasted
