Answer:
See below.
Step-by-step explanation:
The table shows the total number of students as 572 (bottom right cell in the table.)
The number of students who are 17 or older are the students in the two groups: 17-18 and 19-20.
There are 151 students with ages 17-18.
There are 34 students with ages 19-20.
The total of all students 17 or older is 151 + 34 = 185.
The probability of choosing a student age 17 or older is the number of students 17 or older (which is 185) divided by the total number of students (which is 572).
p(17 or older) = 185/572 = 0.3234 = 32.34%
We round 32.34% to the nearest integer to get 32%.
Answer:
9.76 years turns 900 dollars into 1200 dollars.
Step-by-step explanation:
A(t) = 900*(1.03)^t
1200 = 900 * (1.03)^t Divide by 900
1200/900 = (1.03)^t
1.333 = 1.03^t Take the log of both sides.
- log(1.3333) = t * log(1.03)
- log 1.3333 = .1249
- log 1.03 = .0128
1.249 = 0.0128*t
1.249/0.0128 t = 9.76 years.
Answer:
$675
Step-by-step explanation:
Let
x = original price of laptop
Discount = 10%
Actual price paid = x - 10% of x
= x - .10x
= .90x
Cost of mouse = $13.99
Total amount paid = $621.49
Total amount paid = actual cost of laptop + Cost of mouse
621.49 = .90x + 13.99
621.49 - 13.99 = .90x
607.5 = .90x
x = 607.5 / .90
= 675
Original cost of the laptop = $675
