Suppose Abby tracks her travel time to work for 60 days and determines that her mean travel time, in minutes, is 35.6. Assume th

e travel times are normally distributed with a standard deviation of 10.3 min. Determine the travel time such that 17.36% of the 60 days have a travel time that is at least . You may find this standard normal distribution table or this list of software manuals useful. Give your answer rounded to two decimal places.

Answer:

the answer is 45.28 minutes

Step-by-step explanation:

Let X be the travel time in minutes

X is normally distributed with μ= 36.6 and σ=10.3 i.e. X~N (35.6, 10.3)

The travel time x such that 17.36% of the 60 days have a travel time that is at least x is given by,

P(X>x)= 0.1736

P(X<x)= 0.8264

P(Z<x−35.6/10.3)= 0.8264

P(Z<0.940)=0.8264

x−35.6/10.3= 0.940

x=0.940* 10.3+35.6=45.28

Therefore, x is equal to 45.28 minutes

Solve for x: 4(x+5)=3(x-2)-2(x+2)
Zina [86]

Answer:

x = -10

Step-by-step explanation:

Solve the equation by simplifying according to PEMDAS. Then use inverse operations to solve.

4(x+5) = 3(x-2) -2(x+2)

4x + 20 = 3x - 6 - 2x - 4

4x + 20 = x - 10

3x = -30

x = -10

Find the volume of the rectangular prism.<br><br> 3
12345 [234]

Step-by-step explanation:

How are we supposed to find volume if you don't enter the other elements I.e width, length and height?

But just in case the formulae for finding volume is to multiply is elements. So to find volume multiply is width, length and height.
