Answer: the incubation time that separates the bottom 2.5% from the rest of the incubation times is 24.96 days.
Step-by-step explanation:
Suppose the incubation times are approximately normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = incubation times.
µ = mean time
σ = standard deviation
From the information given,
µ = 23 days
σ = 1 day
The probability value for the incubation time that separates the bottom 2.5% from the rest of the incubation times would be (1 - 2.5/100) = (1 - 0.025) = 0.975
Looking at the normal distribution table, the z score corresponding to the probability value is 1.96
Therefore,
1.96 = (x - 23)/1
x = 1.96 + 23
x = 24.96
Answer: AC = 98
Step-by-step explanation:
A midpoint is a point on a line segment that divides it into <em>two equal parts</em>.
This means AB = BC
AB = 8x - 7
BC = 6x + 7
AB = BC
8x - 7 = 6x + 7
Solve this to find x
Add 7 to both sides
8x = 6x + 14
Subtract 6x from both sides
2x = 14
Divide both sides by 2
x = 7
Now AC = AB + BC
AC = AB + BC
AC = 8x - 7 + 6x + 7
AC = 14x
Substitute 7 for x
AC = 14(7)
AC = 98

The total cost of his purchase is $9.95
Bill has a $10 coupon
He needs to buy 25 balloons
Each balloons cost $1.99
The first step is to divide the coupon amount which is $10 by the cost of the balloon which is $1.99
10/1.99
= 5
The next step is to multiply 5 by the cost of the balloon which is $1.99
5× 1.99
= 9.95
Hence the total cost of his purchase is $9.95
