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 %
A) 14
b) 16
c)-8
d) -37
e) 15
Answer:
Slope = 40
Step-by-step explanation:
Time spent = 70 hours(given)
Fixed charge = $75 (given)
x = Total number of hours (given)
Variable charge = $40 * Total number of hours.
Variable charge = $40x
Fee charged, y = Variable charge + Fixed charge
y = 40x + 75 ($)
The equation of a straight line is given as: y = mx + c
where m = slope
Comparing it with the equation above, m = 40
Answer:
27.2 mm²
Step-by-step explanation:
Area of the triangle = ½*base*height
base = 8 mm
height = 6.8 mm
Area = ½*8*6.8
= 4*6.8
= 27.2 mm²
