— 2x — 6 = 3x — 21

Help me anyone

Answers

Answer 1

Answer:

Step-by-step explanation:

-2x+3x=-21+6

or x=-15

Answer 2

Answer:

x=3

Step-by-step explanation:

-2x-6=3x-21

Add 21 to both sides of the equation

-2x-6+21=3x-21+21-2x+15=3x

Add 2x to both sides of the equation

-2x+2x+15=3x+2x15=5x

Divide each side by 5 to isolate x

15÷5=5x÷53=x

If amount of utility bill is normally distributed with a mean of $105 and a standard deviation of $20. What percentage of your bills would you expect to be between $85 and $125?

Answers

Answer:

68% of your bills between $85 and $125

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = $105

Standard deviation = $20

What percentage of your bills would you expect to be between $85 and $125?

85 = 105 - 20

125 = 105 + 20

Within one standard deviation of the mean, so by the Empirical Rule, 68% of your bills between $85 and $125

Answer:

C) 1/3, 2, √7

Step-by-step explanation:

√7= 2.6

1/3= 0.3

2=2

1/3, 2, √7

C.

*if using a calculator*

1/3= .333

square root 7 equals about 2.646

therefore, we know .333 (1/3) is the smallest out of the numbers and 2.646 (sqr root 7) is the biggest.

*if you cannot use a calculator*

We know 1/3 is less than 1 because 3/3 would equal 1 and we only have 1/3.

We don’t know the square root of 7, however we know that it has to be between 2 and 3 because the square root of 4 is 2 and the square root of 9 is 3. 7 is between those two numbers, so therefore we know that the square root would have to be between 2 and 3.

Knowing that, we could figure out that since 1/3 is less than 1 it would be the smallest. Since the sqr root of 7 is between 2 and 3, it would be bigger than 2 and the biggest out of the 3.

Conclusion:

The order is 1/3, 2, sqr root 7

20 mins.        how many mins?

16    =   12       cross multiply       16? = 240   divide by 16     240 divided by 16 = 15 miles

20          ?                                                                                because 15 x 16 = 240
