Step-by-step explanation:
1/2(4-14y)=y+50
1/(8 - 28y) = y + 50
8y - 400 - 28y² +
Now you can solve
Parentheses (brackets/braces) are done first according to the order of operations.
Answer A
The experimental probability that the high temp will be below 45 F on the 29th day is, 4.5 out of 29 days, that is because 20 of the days have had lower temperatures, so they left 9 days of and from those 9 days, they could be lower or greater that 45F (50% each side), that is:
4.5/29 = 0.155 = 15.5%
that is the exp probability
Answer:
1. $0.24
2. 89.2 miles
Step-by-step explanation:
To get the unit price, divide the total price by the amount that was purchased.
1. 3.12/13 = $0.24
For the second one, get the distance traveled per hour first then multiply by 8.
22.3 / 2 = 11.15
11.15 x 8 = 89.2
