Answer: 2)The probability of drawing a red cube is 3/5 and the probability of drawing a blue cube us 2/5.
3) No the probability of selecting a red cube is not equal to probability of selecting a blue cube because the outcomes 3/5 and 2/5 are not equal.
Step-by-step explanation:
Answer:
1. $11.50 2a. 25 2b. Decrease by 10
Step-by-step explanation:
1. Let's write Marietta's wage before a raise as x
$12.25 = x + $0.75
$12.25 - $0.75 = x
x = $11.50
2a. Let's substitute p with the actual value ($170)
170 = 8n - 30
200 = 8n
n = 200/8 = 25
2b.
p = 8*25 - 40
p = 200 - 40 = 160
160 < 170 so the profit decreased
It decreased by 10 (170 - 160).
Let C be the number of cats and B be the number of birds.
Each cat has 4 legs while each bird has 2 legs. Thus,
4C + 2B = 22
2B = 22 - 4C
Each cat and each bird has 2 eyes
2C + 2B = 16
Substituting 2B
2C + 22 - 4C = 16
2C = 6
C = 3
2B = 22 - 4(3)
B = 5
2 cats and 5 birds
.0000079 because you would have to go 6 back since its negative
