Answer:

A

Step-by-step explanation:

Random sampling is a sampling method where each sample has an equal chance of being chosen. The random sample chosen is meant to be an unbiased representation of the population.

If 30% of the sample uses the app, it means that 30% of the population are likely to use the app

Answer:

I think the answer would be n = 9/4

Answer:

2/3rds

Step-by-step explanation:

for 1 cup of flour you multiply 3/4th by 4 then devide by 3 giving you one cup of flour, now to keep it balanced you do the same to the milk, thus multiplying 1/2 by 4 then dividing it by three, which is 2, you then divide 2 by 3 giving you yours answer, 2/3rds

Answer:

A recipe calls for 1/2 cup of milk for every 3/4 cups of flour. How much milk is required for every cup of flour. *

Step-by-step explanation:

So for every  1/2 a cup is  3/4 cups of flour so if  you  need to know how much cups of flour  is  used for 1 total cup of  milk you have to  add you  multiply  it is optional if you add  put  the  two  fractions next to each other  you need to  add to the  side witch  the numbers are  3 so  3+3 is  6  so you got the answer just put  the number  4 under the  6 and  it will be 6/4  or you could say 1  2/4 or 1  1/2 .

Answer:

[tex]Given,\\y = 4x+1......(1)\\y = 2x^2+7x-1.............(2)\\Equating~equation (1)~and~(2),\\4x+1 = 2x^{2} +7x-1\\or, 2x^{2}+7x-4x-1-1=0\\or, 2x^{2} + 3x-2=0\\or, 2x^{2} +4x-x-2=0\\or, 2x(x+2)-1(x+2)=0\\or, (x+2)(2x-1)=0\\i.e. x=-2 ~or~ \frac{1}{2} \\When~x=2,~equation(1)~becomes ~y=4(-2) +1=-7\\When~x=-\frac{1}{2},~equation (1)~becomes~y=4(\frac{1}{2}) +1 = 2+1=3[/tex]

So, the required values of x are -2 and 1/2 and that of y are -7 and 3.

Answer:

The second choice. Because the x-coordinate in the second choice is constant unlike the others, which is a property of a function.

Answer:

Step-by-step explanation:

You want to reverse the algebra and solve for y. First you want to subtract the 'a' to both sides.

x - a = -2by^2

Divide by -1 on both sides

-x + a = 2by^2

Divide by 2b on both sides

(-x + a)/2b = y^2

Take the square root of both sides

[tex]\sqrt{(-x+a)/2b}=y[/tex]

Answer: x=36°

Step-by-step explanation:

The four interior angles of a quadrilateral always equal 360°, so:

(x+16)+(4x-8)+(4x-8)+x=360

Combine like terms:

360=10x+0

360=10x

36=x

Answer:

Line 1: Undefined

Line 2: -4/3

Line 3: 4/3

Line 4: Undefined

Line 5: 7/3

Line 6: -7/3

Line 7: 0

Line 8: 0

Line 9: Undefined

Line 11: 0

Line 10 & 12: Undefined

Step-by-step explanation:

Use the slope formula (you can just search up the slope formula)

Also, always remember that a vertical line's slope will be undefined and a horizontal line's slope will be 0 (zero).

I hope this helps!

Answer:

Charles's reasoning is wrong.

Step-by-step explanation:

Lupita has 7 pounds for 16.8 and Charles has 5 pounds for 16.8.

Let's set up ratios.

So Lupita got the best deal, not Charles. Poor him.

Answer:

C. 55°

Step-by-step explanation:

The computation of mAC is shown below:

Given that

Diameter AB would be parallel to CD

McD = 70

Based on the attached diagram and the above information

mAC is

= (180 - 70) ÷ 2

= 55 degrees

hence, the correct option is third

Answer:

The fraction 4/14 is equal to 2/7 when reduced to lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (2/7) by the same interger number, ie, multiply by 2, 3, 4, 5, 6

Answer:

$3.90

Step-by-step explanation:

To get from 8 to 40, you multiply by 40/8, so you have to do the same to $.78. .78 * 40/8 is equal to 3.9, which would be $3.90.

Answer:

The answer is below

Step-by-step explanation:

The system of equations:

8x-9y+13z=11

-8x-5y+5z=15

3x+4y-8z=-10

The equations can be represented in matrix form as:

AX = B

X = A⁻¹B

Therefore:

[tex]\left[\begin{array}{ccc}8&-9&13\\-8&-5&5\\3&4&-8\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{c}11\\15\\-10\end{array}\right]\\\\\\\left[\begin{array}{c}x\\y\\z\end{array}\right]=\left[\begin{array}{ccc}8&-9&13\\-8&-5&5\\3&4&-8\end{array}\right] ^{-1}\left[\begin{array}{c}11\\15\\-10\end{array}\right]\\[/tex]

[tex]\left[\begin{array}{c}x\\y\\z\end{array}\right]=\left[\begin{array}{ccc}\frac{1}{19} &-\frac{1}{19}&\frac{1}{19}\\-\frac{49}{380}&-\frac{103}{380}&-\frac{36}{95} \\-\frac{17}{380}&-\frac{69}{380}&-\frac{28}{95} \end{array}\right] \left[\begin{array}{c}11\\15\\-10\end{array}\right]\\\\\\\left[\begin{array}{c}x\\y\\z\end{array}\right]=\left[\begin{array}{c}-0.74\\-1.69\\0.13\end{array}\right] \\[/tex]

Answer:

  B' = (18, -16)

Step-by-step explanation:

Dilating means to stretch or shrink a figure. The scale factor tells us how much we are stretching or shrinking. The scale factor is 2, so the coordinates are multiplied by 2.

Answer:

(1,2)

Step-by-step explanation:

The solution would be where both lines intersect.

In this case, the intersected point is (1,2)
