Find z such that 87.7% of the standard normal curve lies to the left of z. (Round your answer to two decimal places.)
Lady_Fox [76]

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

Z = \frac{X - \mu}{\sigma}

Z = \frac{2 - 2.4}{0.35}

Z = -1.14

Z = -1.14 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.

The distance between two cities on a map is 3.5 centimeters. The map uses a scale in which 1 centimeter represents 20 kilometers
Inessa05 [86]
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! :)

Finding an Equation of a Tangent Line In Exercise, find an equation of the tangent line to the graph of the function at the give
devlian [24]

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)
