Suppose the average commute time of your employees is unknown. The standard deviation of their commute time is estimated as 24.5

Leona [35]

The number of employees is 91.

According to the statement

Given that the standard deviation = 24.5

The width in the question = 13

We solve for the margin of error E.

E = width / 2

E= 13/2 = 6.5

At 90%

Alpha = 1-0.90

= 0.1

Alpha/2 = 0.1/2 = 0.05

Z 0.05 = 1.576

Now find the Sample size n

= ((1.576x24.5)/2)²

= 90.8

= 91

So, The number of employees is 91.

At a race track you have the opportunity to buy a ticket that requires you to pick the first and second place horses in the firs

rewona [7]

Answer:

4032 different tickets are possible.

Step-by-step explanation:

Given : At a race track you have the opportunity to buy a ticket that requires you to pick the first and second place horses in the first two races. If the first race runs 9 horses and the second runs 8.

To find : How many different tickets are possible ?

Solution :

In the first race there are 9 ways to pick the winner for first and second place.

Number of ways for first place - $^9C_1=9$

Number of ways for second place - $^8C_1=8$

In the second race there are 8 ways to pick the winner for first and second place.

Number of ways for first place - $^8C_1=8$

Number of ways for second place - $^7C_1=7$

Total number of different tickets are possible is

$n=9\times 8\times 8\times 7$

$n=4032$

Therefore, 4032 different tickets are possible.

Given angle EFG has angle bisector FH, where EF = GF, find the value of y if EH = 5y + 10 and HG = 28 - y.

Whitepunk [10]

Answer:

y = 3

Step-by-step explanation:

*As seen in the photo, the fact that EF = GF and the bisector being there makes EH = HG.

5y + 10 = 28 - y

*Add y to both sides.

6y + 10 = 28

*Subtract 10 from both sides.

6y = 18

*Divide both sides by 6.

y = 3
