Answer:
ST = 23
RU = 8
SV = 5
SU = 10
Step-by-step explanation:
UV = SV = 5
ST = UT = 23
RU = RS = 8
SU = SV + UV = 5 + 5 = 10
Answer:
$32
Step-by-step explanation:
Put 8 where d is, and do the arithmetic.
amount left = 72 -5·8 = 72 -40 = 32

Answer:
Step-by-step explanation:
If they can be rounded to 70 to the nearest 10s. Then they are from 65 to 74.
Their sum is 136.
If we use 136 divided by 2 we get 68.
Since they're distinct, so one can be 67 and one can be 69
Step-by-step explanation:
With each draw, the probability of selecting a green marble is 2/3 and the probability of selecting a yellow marble is 1/3.
To pick two of the the same color, they can either pick green twice or yellow twice.
P = (2/3)(2/3) + (1/3)(1/3)
P = 5/9
To pick two different colors, they can either pick green first then yellow, or yellow first then green.
P = (2/3)(1/3) + (1/3)(2/3)
P = 4/9
Expected value for Derek is:
D = (5/9)(-1) + (4/9)(1)
D = -1/9
The expected value for Mia is:
M = (5/9)(1) + (4/9)(-1)
M = 1/9
