Answer:

median = 10

mean = 10.9

Step-by-step explanation:

These are the answers because:

1) Whenever, there is an even set of numbers for the median, you have to take the two middle numbers in the number set given and then add them. After you add them, you have to divide them by 2.

In this case, it would be:

10 + 10 = 20

20/2 = 10

2) 10.9 is the answer for mean because first, you need to add all the numbers in the set. If you add

8 + 8 + 10 + 10 + 10 + 12 + 13 + 16 you would get 87. Then, you have to divide by how many numbers there are in the number set. In this case it would be 87/8 which is 10.875

Once you round it, you will get 10.9

Answer:

0.17619

Step-by-step explanation:

We solve using z score formula

= z = (x-μ)/σ,

where x is the raw score = 5 accidents

μ is the population mean = 6.4 accidents

σ is the population standard deviation = 1.5

z = 5 - 6.4/1.5

= -1.4/1.5

= -0.93333

Approximately to 2 decimal places = -0.93

Determining the probability value from Z-Table:

P(x< 5) = P(z = -0.93) = 0.17619

Converting this to percentage =

The probability of weeks you would expect to have less than 5 accidents is

0.17619

We are asked in the question:

What proportion of weeks would you expect to have less than 5 accidents?

Proportion is also the same as:

Therefore, the proportion of weeks that you expect to have less than 5 accidents = 0.17619

17.62% of the accidents would be less than 5 accidents.

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\where\ \mu=mean,x=raw\ score,\sigma=standard\ deviation[/tex]

Given that μ = 6.4, σ = 1.5:

For x < 5 accidents:

[tex]z = \frac{5-6.4}{1.5}=-0.93[/tex]

From the normal distribution table, P(x < 5) = P(z < -0.93) = 0.1762 = 17.62%

17.62% of the accidents would be less than 5 accidents.

Step-by-step explanation:

This is a problem in simple interest:  i = prt, where:

p is the principal (intial amount), i is the interest, r is the annual interest rate and t is the time in years.

                                                    i

Solving i = prt for t, we get t = ------

The first thing you want to do is make the fractions improper . Then what you want to do next is add up the gallons of gas she used from her home to her grandparents' home and the gas she used from her grandparents' home to her cousins and you see what 21/5 + 41/10 is and you get 8.3 , So that's means she used 8.3 miles of gas and she has 15.3 gallons of gas left over because she started out with 23.3 miles .

This exercise desires to test our   knowledge of units conversion,

now, given that on the map 1 inch represents 4 miles

the distance of 1mile when converted to inches ordinarily would be

1mile is 63360 inches

since on the map

1 inch represents 4 miles

63360 inches represents  Xmiles

cross multiply we have

X would be = 63360*4

On a map one mile would be 253440 miles
