Answer:
width: 15 inches; length: 20 inches
Step-by-step explanation:
The equation tells you the product of width (x) and length (x+5) is 300, so you're looking for factors of 300 that differ by 5.
300 = 1·300 = 2·150 = 3·100 = 4·75 = 5·60 = 6·50 = 10·30 = 12·25 = 15·20
The factors in the last pair on this list differ by 5, so we have ...
- width = 15 inches
- length = 20 inches
Answer:
Step-by-step explanation:
5 is a factor of 15 and 35
15:35 = 3:7
Answer:
P = 68/552 = 0.123 or 12.3%
Step-by-step explanation:
First, let's calculate the probability of getting a lemon donut. We have only 4 lemon donut among 24 donuts, so probability is:
P(A) = 4/24
Next, as we already ate the lemon donut, we only have 23 donuts now, and among these 23, 17 are custard filled, so probability of choosing one of those is:
P(B) = 17/23
But we want to know the probability that the custard filled donut is choosen after you eat the lemon one so:
P(B|A) = P(A) * P(B)
Replacing:
P(B|A) = 4/24 * 17/23
P(B|A) = 68/552 = 0.123 or 12.3%
