Answer:
$11
Step-by-step explanation:
to find the difference you subtract
56 - 45 = 11
Answer:
a) z = 1.16
b) P(x ≥ 2) = 0.8508
c) z = 1.555
Step-by-step explanation:
a) Find z such that 87.7% of the standard normal curve lies to the left of z.
Lies to the left, so it has a pvalue of 0.877. This is z = 1.16
b) Assume that x has a normal distribution with the specified mean and standard deviation. Find the indicated probability.
μ = 2.4; σ = 0.35
P(x ≥ 2) =
This is 1 subtracted by the pvalue of Z when X = 2, in which



has a pvalue of 0.1492.
So
P(x ≥ 2) = 1 - 0.1492 = 0.8508.
c) Find z such that 6% of the standard normal curve lies to the right of z.
To the right, so z has a pvalue of 1-0.06 = 0.94%. So z = 1.555.
Your answer is going to be $9.60
Aloha!
To figure out this equation this is what you'd do!
First. The distance in centimeters is 3.5
Second, identify how many kilometers your trying to get.
Third, You are going to multiply 3.5(centimeters) by the 20 kilometers.
Lastly, the answer is 70 kilometers.
So, to answer you question.. The answer is 70 kilometers is the distance between the two cities.
I hope this helps!
Adios! :)
Answer: y = 2.5(x-1)
Step-by-step explanation:
Step 1
Find the point of tangency.
It's given as (x,y)= (1,0)
Step 2
Find the first derivative, and evaluate it at x=1
f'(x) = 5/2 × d(lnx)/dx = 5/2 × 1/x = 5/2x
f'(x) = 5/2 = 2.5
The slope of the tangent line at this point is m= 2.5
Step 3
Find the equation of the tangent line at (1,0) with a slope of m=2.5
y−y1 = m(x - x1)
y-0 = 2.5(x-1)
y = 2.5(x-1)
