Answer:

Independent-samples t-test.

Step-by-step explanation:

We are looking for the appropriate design for testing the significance of the difference between the means.

Now, there is a parametric test known as the Independent Samples t Test and what this test does is that it compares the mean of two independent groups in order to find out whether there is statistical evidence that the related population mean is significantly different.

Thus, the test to be used here is Independent-samples t-test.

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle

2x - 2 = 45 + x

2x - x = 45 + 2

x = 47°

Answer:

x = 47

Step-by-step explanation:

Finding the third angle (y) of the triangle:

- Since angles on a straight line add up to 180:

2x -2 + y = 180

y = -2x + 2 + 180

= -2x + 182

Hence, the third angle of the triangle is -2x + 182.

Since all 3 angles of a triangle add up to 180°:

-2x + 182 + x + 45 = 180

-2x + x + 227 = 180

-2x + x = 180 - 227

-x = -47

x = 47

Hence, x = 47

Answer:

7

Step-by-step explanation:

A square has 4 sides, all of equal length. We can simply find the square root of the area to find the length and width, or length of each side. So to find the length, you find the square root of the area.

[tex] \sqrt{49} = 7[/tex]

Answer: 51 notes span 6 octaves.

Step-by-step explanation:

The word "octave" is a Latin word that means "eight".

In an instrument, Each octave is made up of 8 musical notes.

If we have 51 notes , the number of octaves can be made in it = [tex]\dfrac{51}{8}[/tex]

[tex]=6.375\approx6\ \ \ \ \ \text{[Rounded to the nearest whole number]}[/tex]

Hence, 51 notes span 6 octaves.

Answer:

x = 9

Step-by-step explanation:

combine all the equations and set it equal to 360

10x+ 7 + 88 + 127 + 5x+3 = 360

then combine like terms

15x + 225 = 360

then solve the equation by moving 225 to the right side of the equation

15x = 135

divide both sides by 15

x = 9

Answer:

set of related events, movements, or things that follow each other in a particular order.

Step-by-step explanation:

a sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence.

Answer:

230500×100/8= 2881250

Answer:

no solution

Step-by-step explanation:

1/2(4x+14)=2(x-7)

Multiply both sides by 2.

4x + 14 = 4(x - 7)

4x + 14 = 4x - 28

Subtract 4x from both sides.

14 = -28

Since 14 = -28 is a false statement, there is no solution for this equation.

Answer:

y=-x+3.

Step-by-step explanation:

The graph goes down one and right one before making another point. This means that the slope is -1/1. Simplify and you get -1. So far we have y=-1x. -1x is the same as -1. Now we have y=-x. The graph intersects the y-axis at the point (0,3). This makes our y-intercept 3. Our final equation is y=-x+3.

Answer:

division, I mostly use it and I find it easy

Step-by-step explanation:

The price of a game discounted by 18% is 0.82x cuz 82% is left

the price of the toy is 1.18x because x + 0.18x

the volume of water is  7/10x because 7/10 is left

the total amount of flour is 13/10x because 10/10x + 3/10x

Hi sorry for the late response, I know the assignment was due at 5pm today but anyway here is the answer.

System:

d= 5(0.75-t)

d= 20t

20t = 3.75 -5t

Define Variables:

d = how far Carol Skied

t = time it took Carol to go up/down

Solve:

20t = 3.75 -5t

20t + 5t = 3.75 -5t + 5t            

25t = 3.75

25t/25 = 3.75/25

t = 0.15

Now we plug in the time into the Distances:

20t = 3.75 - 5t

20(0.15) = 3.75 - 5(0.15)

3 = 3.75 - 0.75

3 = 3

Solution as Sentence:

Carol Skied 3 miles

Answer:To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...

To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

To find the y-intercept, set x = 0 \displaystyle x=0 x=0.

answer is in there at the bottem

Step-by-step explanation:

Answer:

y = 5

Step-by-step explanation:

4×(x -3y = -6 ) ➡ 4x - 12y = -24

4x -12y - 4x +9y = 9 - 24 ➡ -3y = -15

y = 5 use this value to find x

x - 3×5 = -6

Answer:

4

Step-by-step explanation:

since it's all addition, we can remove the parentheses

[tex]3x + x + 10 + 5x + 2x + 2 = 56[/tex]

Now we combine like terms

[tex]3x+x+5x+2x+10+2=56[/tex]

[tex]11x+12=56[/tex]

We subtract both sides by 12 to get,

[tex]11x=44[/tex]

now we divide both sides by 11

[tex]x=\frac{44}{11}[/tex]

[tex]x=4[/tex]

Answer:

D. 60

Step-by-step explanation:

Since the question stated that the number of marbles given out to his 6 friends were equal, we are certain that the total number of marbles is a factor or multiple of 6.

The only other assumption here is the number of marbles given has to be whole number. This means we just have to go through the answer choices and pick the one that is a multiple of 6.

A. 15 - This is wrong as 15 is not a multiple of 6.

B. 33 - This is wrong as 33 is not a multiple of 6.

C. 56 - This is wrong as 56 is not a multiple of 6.

D. 60 - This is CORRECT as 60 is a multiple of 6.

If Jorge gives each of his friends 10 marbles each, it would bring the total number of marbles to be 60.
