The points (0, 0) and (5, 10) lie in the graph of this linear function. Which equation represents the same linear function? A. B. x = 5 C. D. y = 2x

Answers

Answer:   y = 2x, D.

Step-by-step explanation:  We can calculate the slope of the line between these two points:  Rise/Run:

Rise: (10-0)=10

Run:  (5-0) = 5

Rise/Run = 10/5 = 2

The y-intercept is zero (it is the value of y when x=0, which we are given as (0,0)).

The line between these two points is thus y=2x+0, or

y = 2x.  Looks like D.

Answer:

D. y=2x

Step-by-step explanation:

0x2=0 and 5x2=10. That's really it, simple math

candy comes in large bags of 75 candies, a 1 pound bag, and a large bags with multiple fun-size packs. Jenny randomly opened 12 of the fun-size packs of candies from a bag. The colors she found in each pack are shown in the table.

How does the mean number of reds found in the samples compare to the mean number of purples? Is Jenny more likely to get more of one particular color if she opened 12 more packs of candies.​

Answers

Answer:

the mean of the red is 1.75, while the mean of the purple is 2.25

Step-by-step explanation:

LMK if this helps!

hope it does!

The mean number of red (1.75) is 0.5 less than the mean number of purple.

What is Mean?

Mean is simply defined as the average of the given set of numbers. The mean is considered as one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.

Candy comes in large bags of 75 candies, a 1 pound bag, and large bags with multiple fun-size packs.

Jenny randomly opened 12 of the fun-size packs of candies from a bag.

The mean number of reds will be

[tex]\rm Mean_{r} = \dfrac{2+1+4+2+1+2+1+0+1+3+3+1}{12}\\\\Mean_{r} = \dfrac{21}{12}\\\\Mean_{r} = 1.75[/tex]

The mean number of purples will be

[tex]\rm Mean_p = \dfrac{2+2+1+3+5+2+2+2+4+2+2+0}{12}\\Mean_p = \dfrac{27}{12}\\\\Mean_p =2.25[/tex]

The mean number of red (1.75) is 0.5 less than the mean number of purple.

Step-by-step explanation:

Simple interest is the agreed upon amount that was first deposited. Even if the depositor leaves his interest in the account, the amount paid is on the account is on the 5000 dollars, not the 5100 it will be at the end of the second year.

i = p * r * t

p = 5000 dollars

r = 2% each year

i = 2/ 100 = 0.02

i = 5000 * 2/100 * 2

i = 200 dollars after 2 years.

Which expression is equivalent to n2 + 26n + 88 for all values of n?

(n + 8)(n + 11)
(n + 4)(n + 22)
(n + 4)(n + 24)
(n + 8)(n + 18)

Answers

Answer:

Option B is correct.

Step-by-step explanation:

Our expression is:

n² + 26n + 88

Let's check all of our options to see if any option is accurate.

Option A:

(n + 8)(n + 11)

=> n² + 11n + 8n + 88

=> n² + 19n + 88

n² + 19n + 88 ≠ n² + 26n + 88

Option B:

(n + 4)(n + 22)

=> n² + 22n + 4n + 88

=> n² + 26n + 88

=> n² + 26n + 88 = n² + 26n + 88 ✔

Option C:

(n + 4)(n + 24)

=> n² + 24n + 4n + 96

=> n² + 28n + 96

=> n² + 28n + 96 ≠ n² + 26n + 88

Option D:

(n + 8)(n + 18)

=> n² + 18n + 8n + 144

=> n² + 26n + 144

=> n² + 26n + 144 ≠ n² + 26n + 88

Conclusion:

So, after working on this problem, we can conclude that Option B is our answer. Hoped this helped

Answer:

A = 8a + [tex]\frac{1}{2}[/tex]πa²

Step-by-step explanation:

The figure consists of a rectangle and a semi- circle

area of rectangle = 4 × 2a = 8a

area of semi- circle = [tex]\frac{1}{2}[/tex]πr² ( r is the radius = a )

                                = [tex]\frac{1}{2}[/tex]πa²

Answer:

r=1/4

Step-by-step explanation:

Answer:

r = 1/4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

[tex](\frac{5}{3}r - r) + (\frac{1}{3}) = 2r[/tex] [tex]\frac{2}{3}r+\frac{1}{3} = 2r[/tex]

Step 2: Subtract 2r from both sides.

[tex]\frac{2}{3}r +\frac{1}{3} - 2r = 2r - 2r[/tex] [tex]\frac{-4}{3}r+\frac{1}{3}=0[/tex]

Step 3: Subtract 1/3 from both sides.

[tex]-\frac{4}{3}r+\frac{1}{3} -\frac{1}{3} =0-\frac{1}{3}[/tex] [tex]-\frac{4}{3}r=-\frac{1}{3}[/tex]

Step 4: Multiply both sides by -3/4.

[tex]-\frac{4}{3}r*\frac{3}{-4} =\frac{-1}{3} *\frac{3}{-4}[/tex] [tex]r = \frac{1}{4}[/tex]

Therefore, r = 1/4.

Samples are classified as:

Convenient: Drawn from a conveniently available pool.Random: All the options into a hat and drawn some of them.Systematic: Every kth element is taken.  Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.Stratified: Also divides the population into groups. However, only some elements of each group are surveyed.

In this problem, the population is divided into groups, according to the three different age categories, and then 10 people from each category is selected(that is, not all members), hence it is a stratified sample.

-3/4(x+2)=6

What is the answer please explain how u got it​

Answers

Step-by-step explanation:

1.) distribute (-3/(4x+8)=6)

2.) move 8 (-3/4x=-2)

3.) multiply by 4x (-3= -8x)

4.) divide by -8 (x=2.6)

:)

The answer is: x = -10; Step 1- Combine multiplied terms into a single fraction: -3(x+2)/4 = 6. Step 2- Distribute: -3x - 6/4 = 6. Step 3- Multiply all terms by the same value to eliminate fraction denominators: 4 x -3x - 6/4 = 6 x 4. Step 4- Cancel multiplied terms that are in the denominator: -3x - 6 = 4 x 6. Step 5- Multiply the numbers: -3x - 6 = 24. Step 6- Add 6 to both sides of the equation: -3x - 6 + 6 = 24 + 6. Step 7- Simplify: -3x = 30. Step 8- Divide both sides of the equation by the same term: -3x/-3 = 30/-3. Step 9- Simplify: x = -10.

Answer:

400 ft

Step-by-step explanation:

H = 160t - 16t^2 = 16t(10 - t)

The minimum/maximum of a quadratic function is always exactly in between the 0 points (or any other points with equal value, as a parabole is symmetrical).

Let's solve for H = 0

16t(10-t) = 0

t = 0 or 10 - t = 0

t1 = 0, t2 = 10

the maximum is at (t1+t2)/2 = 5

H(5) = 16*5(10-5) = 80*5 = 400

sin(x) = 1/2 and the angles must be between 0 and 180.

We can take the arcsin(1/2) and we get 30 degrees, but that is only half of the answer.

There are two angles for which the y value on the unit circle outputs 1/2.

To find this other value which is in the second quadrant: 180 - 30 = 150.

The other angle is 150 and can be checked by solving sin(150) which outputs 1/2 so we know have the correct answer.

Smaller =  30   Larger = 150.

1. Find the x and y intercept for the function 3x-4y=12

Answers

Answer:  x-intercept = (4, 0) ; y-intercept = (0, -3)

Step-by-step explanation:

To easily solve this problem we need to know two facts:

the y-intercept is 'c' when a line is in the slope-intercept form (y = mx + c)the x-intercept occurs when y = 0

Slope-intercept form

Since 3x - 4y = 12

         3x - 12 = 4y

                  y = ³/₄ x - 3

         ∴ y-intercept is (0, -3)

Solve for x when y = 0

Since 3x - 4y = 12

         3x - 4(0) = 12

                    x = 4

∴ x-intercept is (4, 0)

We can check our answer by graphing the line and seeing if it passes through the intercepts we calculated. Since it does (see graph below), then the answers we calculated are correct.

He tiptoed into Marie's bedroom and found her sleeping soundly, snugly tucked under her pink comforter. Sam bent over and kissed his beloved five-year-old daughter's forehead. "Thanks, dear. If it was not for you, I would never have turned over a new leaf," Sam whispered in gratitude, recalling the drunken man he saw a while ago.A year ago, after being retrenched from his computer company, Sam felt dejected and worried about how he was going to provide for his family.
