To find the slope(m), use the slope formula:
And plug in the two points on the line
(-3, 7) = (x₁, y₁)
(5, -1) = (x₂, y₂)
(two negative signs cancel each other out and become positive)
Simplify the fraction
m = -1
Answer:
- The probability that the locker code begins with a prime number is 40%.
- The probability that the last digit of the locker code is an odd number is 40%
Step-by-step explanation:
- Prime numbers are the numbers that only divide with 1 or itself. So in this case it is 5 and 7.
The possible combinations are
1*4*3 (with 5) + 1*4*3(with 7) = 24
Total combinations are 5*4*3=60
(24/60)*100 = 40 %
2. Odd numbers are those which don't divide with 2. So in this case it is 6 and 8.
The possible combinations are
1*4*3 (with 6) + 1*4*3(with 8) = 24
Total combinations are 5*4*3=60
(24/60)*100 = 40 %
Whats the rest of the question?
$2.55. 0.15×3=0.45. So then you would take off 45 cents of the original 3 dollars to get $2.55
I = Prt
I = ($19,200)(12%)(5)
I = $11,520
The boat would cost $11,520 in 5 years.
