Answer: x=6.67

Step-by-step explanation:

Since these parallelograms are similar, we can use proportions to solve for x.

[tex]\frac{15}{9} =\frac{x}{4}[/tex]              [cross multiply]

[tex]60=9x[/tex]            [divide both sides by 9]

[tex]x=6.67[/tex]

Now, we know that x=6.67.

Answer:

20/3

Step-by-step explanation:

9/4=15/x

cross multiply and get:

9x=15x4

9x=60

divide both sides by 9 so

x=60/9 which when simplified is equal to 20/3

Answer:

x=70

x=70

Step-by-step explanation:

A factor is an independent variable that is manipulated in an experiment.

Every factor has two or more levels, which are different values of the factor.

A combination of factor levels is called a treatment.

There is one factor: number of jumps.

This factor has two levels: sets of 10 and sets of 20.

For a single factor experiment, the levels are also the treatments: Jump 10 program and Jump 20 program.

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

Step-by-step explanation:

A subset is a set whose elements belong to another set

If B is a subset of A, B would contain elements of A

Answer:

No, it's not a one-to-one function

Step-by-step explanation:

Given

[tex]f(x) = round(x)[/tex]

Required

Determine if this function is one-to-one

I'll answer this question using the following illustrations;

Assume x = 4.6

[tex]f(x) = round(x)[/tex] would be

[tex]f(4.6) = round(4.6)[/tex]

[tex]f(4.6) = 5[/tex]

Also assume x = 4.8

[tex]f(x) = round(x)[/tex] would be

[tex]f(4.8) = round(4.8)[/tex]

[tex]f(4.8) = 5[/tex]

More generally;

[tex]4.5 \leq\ x\leq\5.4[/tex]

Would result in:

[tex]f(x) = 5[/tex]

Since, there's a always a possibility of f(x) having one value for various values of input x, then we can conclude that the function is not a one-to-one function

The function f(x) = round(x) is not one - to - one since different input values of X could yield the same output.

For instance :

Given that x = 1.4

f(x) = round(x)

f(1.4) = round(1.4)

Output = 1 ( nearest integer)

Since, different input values of X could yield the same the output, then the function is not one - to - one.

Answer:

Step-by-step explanation:

Given the vectors  u = (1, −1, −2) and v = (1, 1, 2),

projection of u on v is expressed as [tex]proj_v u = \dfrac{u*v}{|v|^2}*v[/tex]

u.v = (1, −1, −2).(1, 1, 2)

u.v = 1(1)+(-1)(1)+(-2)(2)

u.v = 1-1-4

u.v = -4

|v| = √1²+1²+ 2²

|v| = √1+1+4

|v| = √6

|v|² = (√6)²

|v|² = 6

[tex]proj_v u = \dfrac{-4}{6}*(1,1,2)\\proj_v u = (\dfrac{-4}{6}, \dfrac{-4}{6}, \dfrac{-4}{3} )[/tex]

Similarly for projection of v on u;

[tex]proj_u v = \dfrac{u*v}{|u|^2}*u[/tex]

|u| = √1²+(-1)²+ (-2)²

|u| = √1+1+4

|u| = √6

|u|² = (√6)²

|u|² = 6

[tex]proj_u v = \dfrac{-4}{6}*(1,-1,-2)\\proj_u v = (\dfrac{-4}{6}, \dfrac{4}{6}, \dfrac{4}{3} )[/tex]

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.
