Answer:
52%
Step-by-step explanation:
13×4= 52%
You just multiply by 4 to get the percentage
Answer:N
Step-by-step explanation:
Answer:
h= 0.25c +4
Step-by-step explanation:
➀ Define variables
Assuming that you are asking for the equation representing the height of the stack, let's start by letting the height of the stack be h inches and the number of cups be c.
➁ Find the increase in height with every additional cup
If an additional cup is stacked on the first cup, the height increment is 0.25 inches. When 2 cups are added, the height increment is 2(0.25)= 0.5 inches. Thus the expression for the increase in height is 0.25c, where c is the number of cups as we have already defined in step 1.
➂ Find the total height of the stack
Since the height of the first cup remains constant at 4 inches tall, the total height of the stack can be represented by the equation:
h= 0.25c +4
-20.85+15.50=-5.35,
basically, you still own the bank 5.50 dollars
Answer:
0.03593
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 17,340
μ is the population mean = 15,000
σ is the population standard deviation = 1300
z score:
z = 17340 - 15000/1300
z =1.8
Probability value from Z-Table:
P(x<17340) = 0.96407
P(x >17340) = 1 - P(x<17340)
= 1 - 0.96407
= 0.03593
The probability that the life span of the monitor will be more than 17,340 hours is 0.03593
