She should use a dot plot because there are various numbers and they aren’t completely far apart meaning it is easier.
Answer:
y= -3/4x+2
Step-by-step explanation:
3x+4y=8
-3x -3x
----------------
4y=-3x+8
Divided by 4 on each sides
y= -3/4x+2
Answer:
Step-by-step explanation:
<u>Lets calculate the points:</u>
- Art - 2 hrs - B (3) ⇒ 2*3 = 6 points
- History - 3 hrs - A (4) ⇒ 3*4 = 12 points
- Science - 4 hrs - C (2) ⇒ 4*2 = 8 points
- Math - 3 hrs - B (3) ⇒ 3*3 = 9 points
- Lab - 1 hr - A (4) ⇒ 1*4 = 4 points
<u>Totals</u>
- Total hours = 13
- Total points = 39
<u>GPA = total points/ total hours</u>
Correct option is C
Answer:
630
Step-by-step explanation:
Answer:
E(Y) = $0.5
Var(Y) = 14.25
you should pay the same amount $0.5
Step-by-step explanation:
E(Y) = = Σ(YP)
P = probability of each outcomes.
Var(Y) = Σ
p − (μ x μ)
E(Y) = (2 x 0.25) +(6 x 0.25) + (0.5 x (-3)) = $0.5
Var(Y) = (
x 0.25) + (
x 0.25) +(
x 0.5) - (
)
= 14.5 - 0.25
Var(Y) = 14.25
for the difference between the payoff and cost of playing to have mean 0, you should pay the same amount $0.5
