Answer:

A common abuse of bar graphs is to. replace bars by pictures and increase both height and width as the variable plotted increases. If a bar graph is to be accurate, it is essential that. the bars all have the same width.

Answer:

the first one

Step-by-step explanation:

Answer:

1.  This is a like term

24 = 24

2. This is not a like term

12x - 6 = 46

3. This is not a like term

33 = 5x + 43

4.This is a like term

1 = 1

5. This is not a like term

7x = -48

6. This is a like term

25 = 25

7. This is a like term

60 = 60

8. This is a like term

47 = 47

9.This is a like term

20.6 = 20.6

10.This is a like term

10 = 10

Step-by-step explanation:

1. 5x + 4x − 6x = 24

5x + 4x = 9x

9x - 6x = 24

3x = 24

We can replace x and turn it into an 8.

3(8) = 24

3 x 8 = 24

24 = 24

This is a like term.

2. 8x + 5 − 4x + 1 = 46

8x + 4x - 5 + 1 = 46

8x + 4x = 12x

12x - 5 + 1 = 46

5 + 1 = 6

12x - 6 = 46

We cannot replace the x with any number to get 46.

So this is not a like term.

3. 33 = 5(x + 8) + 3

5xX= 5x

5 x 8 = 40

33 = 5x + 40 + 3

40 + 3 = 43

33 = 5x + 43

We cannot replace any number with x and get 33.

This is not a like term.

4. 2x + 3(x − 8) = 1

3 x X = 3x

3 x 8 = 24

2x + 3x - 24 = 1

2x + 3x = 5x

5x - 24 = 1

We can replace the x with 5.

5(5) - 24 = 1

5 x 5 = 25

25 - 24 = 1

1 = 1

This is a like term

5. x + x − 2x + 4x = −48

x + x = 1x because x is always a 1

1x - 2x +4x  = -48

1x + 2x = 3x

4x + 3x = 7x

7x = -48

We cannot replace x with any number.

This is not a like term.

6. 2(x + 5) + 3x = 25

2 x X = 2x

2 x 5 = 10

2x + 10 + 3x = 25

2x + 3x + 10 = 25

2x + 3x = 5x

5x + 10 = 25

We can replace the x with a 3.

5(3) + 10 = 25

5 x 3 = 15

15 + 10 = 25

25 = 25

This is a like term.

7. 60 = 4(x + 3) + 2(x − 3)

4 x X = 4x

4 x 3 = 12

60 = 4x + 12 + 2(x - 3)

2 x X = 2x

2 x 3 = 6

60 = 4x + 12 + 2x - 6

60 = 4x +2x +12 - 6

4x - 2x = 2x

60 = 2x + 12 - 6

12 - 6 = 6

60 = 2x + 6

We can replace the x with a 33.

60 = 2(33) - 6

2 x 33 = 66

66 - 6 = 60

60 = 60

This is a like term.

8. 47 = 2(x + 3) + 3(x − 3)

2 x X = 2x

2 x 3 = 6

47 = 2x + 6 + 3(x - 3)

3 x X = 3x

3 x 3 = 9

47 = 2x + 6 + 3x - 9

47 = 2x + 3x + 6 - 9

2x + 3x =  5x

47 = 5x + 6 - 9

6 - 9 = -3

47 = 5x + -3

We can replace the x with a 10.

47 = 5(10) + -3

5 x 10 = 50

47 = 50 + -3

50 + -3 = 47

47 = 47

This is a like term.

9. −2(x + 1.4) − 1.8 = 20.6

-2 x X = -2x

-2 x 1.4 = -2.8

-2x + -2.8 - 1.8 = 20.6

-2.8 - 1.8 = -4.6

-2x + -4.6 = 20.6

We can replace x with a 8.

-2(8) + -4.6 = 20.6

-2 x 8 = -16

-16 + -4.6 = 20.6

20.6 = 20.6

This is a like term.

10. 8 − 2(x + 4) = 10

2 x X = 2x

2 x 4 = 8

8 - 2x + 8 = 10

8 - 8 + 2x = 10

8 - 8 = 0

0 + 2x = 10

We can replace x with 5.

0 + 2(5) = 10

2 x 5 = 10

0 + 10 = 10

10 = 10

This is a like term.

I hope this helped. I am sorry if you get this wrong. Have a wonderful day.

Most of the bars are pretty close to each other.

The answer would be the first choice.

Answer:

Step-by-step explanation:

Answer:

50 20p coins is needed to make 10 pounds

Answer:

36%

Step-by-step explanation:

Answer:

A) Option C: H0: μ ≥ 7; HA: μ < 7

B) test statistic = -1.75

C) Option C: 0.025 ≤ p-value < 0.05

D) Option C: Do not reject H0 since the p-value is greater than α.

E) Option A: There is insufficient evidence to suggest that Americans sleep less than the recommended 7 hours of sleep.

Step-by-step explanation:

We are given;

Population mean; μ = 7

Sample mean; x = 6.7

Standard deviation; s = 2.1

Sample size; n = 150

A) Defining the hypothesis, we have;

Null Hypothesis; H0: μ ≥ 7

Alternative hypothesis; HA: μ < 7

B) Formula for the test statistic is;

z = (x - μ)/(s/√n)

Plugging in the relevant values, we have;

z = (6.7 - 7)/(2.1/√150)

z = -0.3/0.1715

z = -1.75

C) Using online p-value from z-score calculator attached with; z = - 1.75 ; α = 0.01 and one tailed distribution, we have;

The P-Value = 0.040059

Thus,the most appropriate answer is;

Option C: 0.025 ≤ p-value < 0.05

D) P-value is greater than the significance level, thus we fail to reject the null hypothesis.

E) We will conclude that there is insufficient evidence to suggest that Americans sleep less than the recommended 7 hours of sleep.

I think one of two options

C or D

Answer:

7. y= x + 12   8. y= -1 + 4x

Step-by-step explanation:

for 7 all you need to do is subtract x from both sides to get y= 12- x, and to make it perpendicular you need to make the current slope it’s exact opposite so in this case that’s just changing the “-” symbol to an “+”.

for 8 you do the same first step you did in 7 and subtract 4x from both sides to get -y= 1 - 4x. Next you divide everything by -1 (because it’s the number in front of the Y) and you get Y= -1 + 4x

Answer:  2/3

The slash means division, and it also means a fraction, as they are effectively one in the same.

Step-by-step explanation:

Answer:

The Answer is : x= -12

Step-by-step explanation:

[tex]4x-2(x+1)=3x+10\\4x-2x-2=3x+10\\2x-2=3x+10\\2x-3x=10+2\\-x=12\\x=-12[/tex]

Answer:

[tex] \huge \boxed{x = - 12}[/tex]

Step-by-step explanation:

[tex]4x – 2(x + 1) = 3x + 10[/tex]

Expand the terms in the bracket

That's

[tex]4x - 2x - 2 = 3x + 10 \\ 2x - 2 = 3x + 10[/tex]

Subtract 2x from both sides of the equation

[tex]2x - 2x - 2 = 3x - 2x + 10 \\ - 2 = x + 10[/tex]

Subtract 10 from both sides of the equation

[tex] - 2 - 10 = x + 10 - 10 \\ x = - 12[/tex]

We have the final answer as

[tex]x = - 12[/tex]

Answer:

21,22

Step-by-step explanation:

n(n+1)=462

Distribute n through the term in the parentheses.

n2+n=462

Subtract 462 from each side.

n2+n−462=462−462

Write the relationship as a quadratic equation.

n2+n−462=0

Factor the equation.

(n+22)(n−21)=0

Solve.

n+22=0 and n−21=0n=−22 or 21
