Answer:

What is acceleration?

Imagine you are playing golf, and you’ve just set up the golf ball on the tee. You test your grip, take a few practice swings, and peer into the distance at the flag pole marking the first hole for the course. Your wise golf ball guru (who happens to also teach physics) tells you to “Be the ball, young grasshopper.” So you close your eyes and picture the distance the ball must travel. “Yes, young earthworm”, your sensei says, “that distance you see is the displacement you must achieve, displacement is the change in position from one place to another.”

Answer:

y = -4/9x + 1/3 letter H

Step-by-step explanation:

Let's solve for y. 4x+9y=3 Step 1: Add -4x to both sides. 4x+9y+−4x=3+−4x 9y=−4x+3 Step 2: Divide both sides by 9. 9y 9 = −4x+3 9 y= −4 9 x+ 1 3

Answer:

Infinite solutions

Step-by-step explanation:

Suppose there are finite solutions to x > 12

Then there exists a largest solution, which we call X

But X + 1 > X, and X > 12, so by transitivity X + 1 > 12 and thus is an even larger solution

this means X is not the largest solution

Therefore, by contradiction, the assumption that there are only finite solutions is false

Answer:

X

Step-by-step explanation:

The X-axis is the one on the bottom if you are in the first quadrant. The y-axis is on the left or up and down. If you are writing location(I can't remember the name but it looks like this (2,3)) you would write the X-axis down first. Hope this helped!

First we have to find the factors of 35 that by subtracting equal to 2 so

x2 - 7x + 5x - 35

Taking common

x(x - 7) + 5(x - 7)

(x - 7) and (x + 5) are the factors

Answer:

[tex]\frac{11}{36} = 0.3056[/tex] probability that at least one dies shows a 5.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Each dice:

6 sides, one of which is 5.

So 6-1/6 = 5/6 probability of rolling a 5.

Probability of not rolling a five in two rolls:

(5/6)^2 = 25/36

Probability of rolling a five in at least one of the rolls:

[tex]p = 1 - \frac{25}{36} = \frac{36}{36} - \frac{25}{36} = \frac{11}{36} = 0.3056[/tex]

[tex]\frac{11}{36} = 0.3056[/tex] probability that at least one dies shows a 5.

No

Answer:

C.

Step-by-step explanation:

The bottom-right most cell tells us that the total number of students that responded to the survey is 310 students.

To find the answer, we can go through each choice.

A. Females taking Geometry

Row 1 Column 2 tells us that 53 females are taking geometry. 53/310 is about 17%.

B. Females taking Algebra II.

Row 1 Colume 3 tells us that 62 females are taking Algebra II. 62/310 is 20%.

C. Males taking Geometry.

Row 2 Colume 2 tells us that 59 males are taking Geometry. 59/310 is about 19%. Choice C is correct.

D. Males taking Algebra I.

44 out of the total 310 respondents are male and is taking Algebra I. 44/310 is about 14%.

Answer:

C

Step-by-step explanation:

59/310 *100 = 19.03%

so 19%

For the solution [tex](3,\frac{1}{3})[/tex] of the given system of equations, the value of x - y is [tex]2\frac{2}{3}[/tex]

To determine the value of x - y, we will solve the two equations simultaneously

We have

7x + 3y = 8 ------ (1)

6x – 3y = 5 ----- (2)

Solving by the elimination method

Add equations (1) and (2) together

We get

[tex]7x + 6x +3y -3y = 8 + 5[/tex]

Then,

[tex]13x = 13[/tex]

Now, divide both sides by 13

[tex]\frac{13x}{13} = \frac{13}{13}[/tex]

∴ [tex]x = 1[/tex]

Now, substitute the value of x into equation (1)

[tex]7x + 3y = 8[/tex]

We get

[tex]7(1) + 3y = 8[/tex]

[tex]7 + 3y = 8[/tex]

[tex]3y = 8-7[/tex]

Then,

[tex]3y = 1[/tex]

Divide both sides by 3

[tex]\frac{3y}{3} =\frac{1}{3}[/tex]

∴ [tex]y = \frac{1}{3}[/tex]

The solution to the system of equations is [tex](3,\frac{1}{3})[/tex]

Now, for the value of x - y, we will input the values of x and y

That is,

[tex]x -y = 3 -\frac{1}{3}[/tex]

[tex]= 2\frac{2}{3}[/tex]

∴ [tex]x-y =2\frac{2}{3}[/tex]

Hence, the value of x - y is [tex]2\frac{2}{3}[/tex]

$707.9941 rounded is $707.99

Step-by-step explanation:

41%=0.41

1199.99*0.41=491.9959

$1199.99-$491.9959=$707.9941

$707.9941 rounded is $707.99

the four doesn't round up so it would just be $707.99.

Answer:

Step-by-step explanation:

You have to multiply the total members by the percentage.

20X[tex]\frac{20}{100}[/tex] =4

Answer:

H0; u = 50 average revenue equals 50

H1: u not equal to 50, average revenue not equal to 50

This is 2 tailed

Alpha = 0.05

Z critical = 1.6449

We find the test statistics

Mean = 54.7

Sd = 11

n = 32

barX - u/sd/√n

= 54.70-50/11/√32

= 4.70/1.9435

= 2.418

Decision rule: reject H0 if test statistic > critical value. Accept if otherwise

2.418>1.6449

We reject H0

We conclude that average revenue is not equal to zero

C. P(z>=2.418) = 0.9922

1 - 0.9922

= 0.0078 (I used Ms excel here)

0.0078 < 0.05

So we Reject h0
