If you have 5 blue marbles, 8 yellow marbles, and 2 green marbles. What is the probability of pulling a yellow marble?

Answers

Add all them up. 5+8+2 = 15

How many yellows? 8/15 = 0.533 ~~ 53%

Answer: 8/15

Step-by-step explanation: take all the color of marbles and add them together. There is where you get your denominator of 25. Next, since you are finding for yellow marbles, take the number of yellow marbles (8) and that will be your numerator.

The house will cost approximately $246,359.85 seven years from now.

What is compound interest?

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

In this problem,

P = $140,000

r = 0.07

n = 1 (compounded annually)

t = 7.

Plugging in these values.

A = $140,000 (1 + 0.07/1)^(1 x 7)

A = $140,000 (1.07)^7

A = $246,359.85

Therefore,

The house will cost approximately $246,359.85 seven years from now.

Find the ratio of the given one: 20/200 = 0.1


this means the sugar (y) is 0.1 amount of soda (x)

Multiply the amount of soda by 0.1:


Formula is y = 0.1x

Answer Below/Step-by-step explanation:

Formula : y = kx or y = k/x

Thus since the formula is y = kx then we can substitute:

y = 20

k = ?

x = 200

20 = ? / 200

? = 10

Therefore for the rest of the blank

100/10 = 10

500/10 = 50

1000/10 = 100

What are the x- and y-intercepts of the graph of 5x – 4y = 20?

Answers

Answer:

The x-intercept is (4, 0)

The y-intercept is (0, -5)

Step-by-step explanation:

The x-intercept is always (x, 0)

Knowing this we can sub 0 for y in the equation so we can find the x-intercept

[tex]5x-4y=20\\5x-4(0)=20\\5x=20[/tex]

Now solve for x

[tex]5x=20\\\frac{5x}{5} =\frac{20}{5} \\x=4[/tex]

The x-intercept is (4,0)

The y-intercept is always (0, y)

Knowing this we can sub 0 for x in the equation so we can find the y-intercept

[tex]5x-4y=29\\5(0)-4y=20\\-4y=20[/tex]

Now solve for y

[tex]-4y=20\\\frac{-4y}{-4} =\frac{20}{-4} \\y=-5[/tex]

The y-intercept is (0, -5)

Hurrrryyyyy plllzzz. Determine the equation of the line that passes through the given points
(10,2) and (-3,2)

Answers

Answer:

y = 2

Step-by-step explanation:

To determine the equation of the line that passes through (10,2) and (-3,2), we need to determine the slope of the line. Then substitute the slope and any given point in point slope form to obtain the equation of the line.

Finding the Slope of the line:

[tex]\implies \text{Slope} = \dfrac{\text{Rise}}{\text{Run}} = \dfrac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

[tex]\implies \text{Slope} = \dfrac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

Substitute the coordinates of the given points:

[tex]\implies \text{Slope} = \dfrac{2 - 2}{-3 - 10 }[/tex]

Simplify the equation to determine the slope:

[tex]\implies \text{Slope} = \dfrac{0}{-3 - 10 }[/tex]

∴ 0 divided by ANY number is ALWAYS 0.

[tex]\implies \text{Slope} =0[/tex]

Finding the equation of the line:

Point slope form formula: y - y₁ = m(x - x₁)

x₁ and y₁ are the coordinates of any given point.m is the slope

Substitute the values in the point slope form:

[tex]\implies \text{Equation of line:} \ y - y_{1} = m(x - x_{1} )[/tex]

[tex]\implies \text{Equation of line:} \ y - 2 = 0(x - 10)[/tex]

Simplify the equation to determine the equation of the line:

Any number multiplied by 0 is 0.

[tex]\implies \text{Equation of line:} \ y - 2 = 0[/tex]

[tex]\implies \text{Equation of line:} \ y = 0 + 2[/tex]

[tex]\implies \text{Equation of line:} \ y = 2[/tex]

Thus, the equation of the line is y = 2.

proportionality of triangles- setup and solve

Answers

You can set up proportions with similar triangles by taking advantage of their side ratios.
By definition, similar triangles have the same angle measures for their corresponding angles, and therefore the corresponding sides have a ratio to them.
For examplle consider the triangles below:
Image from regentsprep
Image from regentsprep
It is given that their corresponding angles have the same measurement, so therefore we can say that they are similar.
Now if we were asked to solve for side ED, then we could do so by setting up a proportion using the side ratios as follows:
AC/DF=CB/FE=BA/DE

Now we can just plug in the lengths for the respective sides:
7/14=6/12=10/DE

Now we can just simplify and solve:
1/2=1/2=10/DE
10/DE=1/2
DE=2(10)=20
This is how we can use proportions to solve for side lengths in similar triangles.
Just make sure you set up your proportions with the corresponding sides, or your ratios might come out wrong.
Just as a fun fact, the fact that side lengths have ratios when the angles are the same is fundamental in trigonometry as well, as you use side ratios there too.
Hope that helped :)

When the graph of any continuous function y = f(x) for a ≤ x ≤ b is rotated about the horizontal line y = L, the volume obtained depends on L. What value of L minimizes the volume in part (c)?

Answers

The value in the part (c) is 1/(b-a) if the graph of any continuous function y = f(x) for a ≤ x ≤ b is rotated about the horizontal line y = L, the volume obtained depends on L.

What is integration?

It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.

We have a graph of any continuous function y = f(x) for a ≤ x ≤ b is rotated about the horizontal line y = L.

For part(c)

[tex]\rm V(L) = \int\limits^b_a {\pi(f(x) -L)^2} \, dx\\\\\rm V(L) = \int\limits^b_a {\pi((f(x))^2 -2f(x)+L^2)} \, dx\\\\\rm V(L) = \pi \int\limits^b_a {(f(x))^2} \, dx-2\pi L \int\limits^b_a {f(x)} \, dx +L^2\pi\int\limits^b_a {} \, dx[/tex]

Now finding V'(L)

[tex]\rm V'(L) = -2\pi \int\limits^b_a {f(x)} \, dx+2\pi L \int\limits^b_a {} \, dx[/tex]

[tex]\rm V'(L) = -2\pi \int\limits^b_a {f(x)} \, dx+2\pi L (b-a)[/tex]

Now equation V'(L) to zero; V'(L) = 0

[tex]\rm -2\pi \int\limits^b_a {f(x)} \, dx+2\pi L (b-a)=0[/tex]

[tex]\rm \int\limits^b_a {f(x)} \, dx= L (b-a)[/tex]

[tex]\rm L = \frac{1}{b-a} \int\limits^b_a {f(x)} \, dx[/tex]

The above expression is representing the critical point.

Now finding V''(L)

V''(L) = 2π(b-a) >0 at L

[tex]\rm L = \frac{1}{b-a} \int\limits^b_a {f(x)} \, dx[/tex]   (minimizines the volume)

Thus, the value in the part (c) is 1/(b-a) if the graph of any continuous function y = f(x) for a ≤ x ≤ b is rotated about the horizontal line y = L, the volume obtained depends on L.

Use your line of best fit from question 5 to find the approximate value of y when x equals 24

Answers

The line of best fit is an illustration of a linear regression

Using the assumed parameters, the value of x when x = 24 is 30.75

How to determine the value of y?

The equation of the line of best fit is not given, and the parameters to calculate the line of best fit are missing.

So, I will assume the following parameter values.

Assume that the line of best fit passes through the points

(x,y) = (1,2) and (5,7)

The slope of the line would be:

m = (7 - 2)/(5- 1)

m = 1.25

The equation is then calculated as:

y =m(x - x1) + y1

This gives

y = 1.25(x - 1) + 2

Expand

y = 1.25x - 1.25 + 2

Evaluate

y = 1.25x + 0.75

When x = 24, we have:

y = 1.25 * 24 + 0.75

Evaluate

y = 30.75

Using the assumed values, the value of x when x = 24 is 30.75
