REY [17]

The equation is asking how much out of Jada's total budget (1545) is spent on electricity a month (47.20).
write this as a fraction 47.20/1545
type into calculator and you get .03055
multiply that by 100 to get it as a percent. you get 3.055%
now round that to the nearest tenth and you get 3.1%

What is the probability that at least one of a pair of fair dice lands of 5, given that the sum of the dice is 8?

o-na [289]

Answer:

0.40

Step-by-step explanation:

to find out the probability that at least one of a pair of fair dice lands of 5, given that the sum of the dice is 8

Let A = sum of dice is 8

B = one lands in 5

P(B/A) = P(AB)/P(A) by conditional probability

P(AB) = sum is 8 and one is 5

So (5,3) or (3,5)

P(A) = sum is 8.

i.e. (2,6) (2,6) (3,5) (5,3) (4,4)

Required probability

= n(AB)/n(A)

= $\frac{2}{5} =0.40$

The wind blew away 24 of your muffins. That was 3/4 of them! How many are left?

forsale [732]

Set up a proportion:

3/4/24 = 1/x

Cross multiply:

3/4x = 24

Divide 3/4 to both sides or multiply by its reciprocal, 4/3:

x = 24 * 4/3

x = 96/3

x = 32

So you had a total of 32 muffins, now subtract this from the amount that blew away to find out how many you have left:

32 - 24 = 8

So you have 8 muffins left.
