Step-by-step explanation:
4. To simplify the expression, multiply J by 1 + the rate:
The expression would be j(1.05)
New price = 35(1.05) = 36.75
5. multiply the cost of each ( t-shirt and cd) by the number of cds bought:
Total = 12x + 7.50x
Simplify by adding the price of each together:
Total = 19.5x
Answer:
5
Step-by-step explanation:
- 7 - (- 12) = - 7 + 12 = 12 - 7 = 5
Answer:
The number of days the number will be greater than 60 is 45.
Step-by-step explanation:
Since there are 80 total numbers and a number of the day can be repeated, then there is the same chance each day of picking one of the numbers. There are 20 numbers greater than 60 between 1 and 80. So, the chances of picking a number greater than 60 each day is 20/80, or 1/4 (25%). This probability is the same each day and we would take the total number of school days (180) multiplied by this probability to get our predicted number of days the number would be greater than 60 during the school year. 180 x .25 = 45.
The percentage of these cars with a fuel efficiency less than 32 mpg is; 90%
<h3>
How to Find the percentage?</h3>
We are can the efficiencies of 10 cars in mpg.
Now, among the 10 cars, the number of cars that have an mpg less than 32 mpg are 9 cars.
Thus, percentage of these cars with a fuel efficiency less than 32 mpg is;
Percentage = 9/10 * 100%
Percentage = 90%
Complete question is;
Here are the fuel efficiencies (in mpg) of 10 new cars; 28, 24, 29, 18, 13, 43, 38, 14, 49, 32. What is the percentage of these cars with a fuel efficiency less than 32 mpg?
