Answer:
She will exercise for 6 hours in four weeks.
Step-by-step explanation:
Summer exercises for 0.5 hour on Monday, 0.5 hour on Wednesday, and 0.5 hour on Friday. There are 3 days where she exercises for 0.5 hour.
3 days X 0.5h = 1.5h each week
For four weeks, multiply the hours each week by 4.
1.5h X 4 weeks = 6h
Therefore Summer will exercise for 6 hours over the course of 4 weeks.
Answer:
d=107
Step-by-step explanation:
7+5^2 *4
PEMDAS
Since there are no parentheses, we do exponents next
7+25*4
Then we multiply
7+100
Then we add
107
We are assuming that the initials are different. Let them be A, B, C, D.
Clearly ABCD is the only possible outcome where the letters are in alphabetical order.
The total number the outcomes, is the number of permutations of these 4 letters.
The first letter can be any of the 4, the second, any of the 3 left (after having picked the first one), the third any of the 2 left (after picking the second one), and the fourth one is only 1 possibility.
So the total number of outcomes (permutations) is 4*3*2*1=24
P(alphabetical order)=1/24
