For the first question, the mean is calculated by adding all the items together and dividing it by the amount of them.

In this case, we add 32000 to 4600 to create 36600, this is the cost for 6 cars. To find the mean, we divide by 6. 36600 divided by 6 is 6100

Answer:

y = 4x + 3

Step-by-step explanation:

We are given the line shown in your question.

We want to write the equation of this line in slope-intercept form

Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept

As we are given the graph of the line, we can pick any 2 points to help us find the equation; in this case, let's take (0,3) and (-1, -1).

First, we need to find the slope of the line

The slope (m) can be found using the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

Let's label the values of the points to avoid confusion and mistakes before calculating.

[tex]x_1= 0\\y_1=3\\x_2=-1\\y_2=-1[/tex]

Now substitute these values into the equation for the slope

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{-1-3}{-1-0}[/tex]

Subtract

m=[tex]\frac{-4}{-1}[/tex]

Divide

m = 4

The slope of the line is 4

Here is the equation of the line so far:

y = 4x + b

Now we need to find b

As stated above, b is the value of y at the y intercept; the y intercept is the point where the line intersects with the y axis. The value of x at this point is 0

One of the points we used to calculate the slope was actually the y intercept point; this point is (0, 3). The value of y at this point is 3, so the value of b is 3

Substitute 3 as b in our equation

y = 4x + 3

Topic: finding the equation of the line

isolate for y:

[tex]16=4y\\\\\frac{16}{4}=\frac{4y}{4} \\\\4=y[/tex]

The value of y is 4.

Answer:

Step-by-step ef(x)=-2x+5……i

and f(-3x)=?

let x=-3x so that

-2x+5=-3x

x=5

substitutinx x into… i

f(x)=-10+5=-5

f(5)=-5………ii

now f(–3x)=f(-15)

scrutinizing… ii ,we can propose that

f(-15)=15.

Thus f(-3x)=15xplanation:

f times x would equal to fx=2x+5 and i think we move the x move to the other side which makes it f=3x+5 and then we plug this equal into f(3x) (i think)  which makes it f(3x+f=3x+5)

The conclusion is that 15% of all students on the baseball team at Ridgemont High like the broccoli option second would be the correct choice.

It is defined as the group of data having the same entity which is related to some problems. The sample is a subset of the population, it is a part of the population.

We have the statement:

Wholesome Food Company asked all students on the baseball team at Ridgemont High School the question, “Do you like broccoli?” and 15% answered “Yes.”

The given conclusions:

There is no particular information given about who likes to eat broccoli, but based on the conclusion and statement, we can say:

15% of all students on the baseball team at Ridgemont High like broccoli.

Thus, the conclusion is that 15% of all students on the baseball team at Ridgemont High like the broccoli option second would be the correct choice.

The triangle in the image seems to be an isosceles triangle which means that two of the angles would be the same.

x would be 54° as well

to find the third angle, subtract all the angles from 180

[tex]180-54-54=72[/tex]

y would be 72°

a) From the Pythagorean theorem, we have

AC² = AB² + BC² = a² + a²   ⇒   AC = √2 a

and

AK² = AB² + BK² = a² + (2a)²   ⇒   AK = √5 a

ABCD and BKLC are perpendicular, so AC and CL are perpendicular and ∆ACL is a right triangle. By the Pythagorean theorem, we have

AL² = AC² + CL² = (√2 a)² + (2a)²   ⇒   AL = √6 a

Now,

AK² + LK² = (√5 a)² + a² = 6a² = (√6 a)² = AL²

which means ∆AKL satisfies the Pythagorean theorem and is a right triangle, so ∠AKL = 90°.

b) We know AC = √2 a and AK = √5 a. By the Pythagorean theorem, we find

CK² = BC² + BK² = a² + (2a)²   ⇒   CK = √5 a

By the law of cosines, we have

AK² = AC² + CK² - 2 AC CK cos(∠AKC)

6a² = 2a² + 5a² - 2√10 a² cos(∠AKC)

cos(∠AKC) = 1/(2√10)

∠AKC = arccos(1/(2√10)) ≈ 80.9°

You are right in that this function is not an odd function. For it to be odd it has to be symmetrical about the origin or equivalently -f(x) = f(-x) which is not the case here.

Answer:

60

Step-by-step explanation:

The mean of a set of numbers is calculated by adding them all together and then dividing the sum by the amount of values in the data set. In this scenario, we know the mean is 30, and there are 3 numbers in the data set, 10, 20, and an unknown number (x).

Let's set up an equation with the information we have.

30 = (10 + 20 + x) / 3

Now we can multiply both sides by 3 ==>

90 = 10 + 20 + x

Combine like terms ==>

90 = 30 + x

Subtract 30 from each side ==>

60 = x

And now you have your answer!

The value of x = 60 would make the mean of the data set 30.

The probability of rolling a sum of 5 is 1/9 or 11.12% if the Luna rolls two number cubes labeled 1-6.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

Luna rolls two number cubes labeled 1-6.

Total number of outcomes = 6×6 = 36

Total number of favorable outcomes = 4

Which is (1, 4), (2,3) (3,2), (4,1)

The probability will be:

= 4/36

= 1/9  or in percentage:

= 11.12%

Thus, the probability of rolling a sum of 5 is 1/9 or 11.12% if the Luna rolls two number cubes labeled 1-6.

You have to rearrange the equation so that y is all by itself on the left and it must be positive. Stay tuned to get the rest of the rule.

x - y = 3                       Multiply the whole equation by -1

-1(x - y = 3)                   Remove the brackets. This gets y to be +

-x + y = - 3                   Add x to both sides of the equation.

-x+x + y = -3 + x           Combine the left. Notice the x's disappear on the left

y = - 3 + x

Now for the rest of the rule. The number in front of the x is the slope. But, you say, there is no number. Well there is. It's 1.

Answer

The slope of the line is 1.
