Answer:

Yeah, you're right. ( But please look at the explanation even though it's long. )

Step-by-step explanation:

First. You need to understand each option:

The first option shows that Jordan is taking $45 dollars and then adding $55 dollars to her bank account.

The second option shows that Harshika spent $45 on lunch and then used $20 more dollars.

The third option shows a plane that went up 600 feet then went down 200.

The fourth option shows that Jorge used $60 dollars to buy a sweater and then added $40 dollars.

Then. Understand the question.

The question is asking which option is telling you that the subject is taking money away or going down from an elevation.

Finally. Eliminate, and solve with sense.

Options 1 and 4 show taking away money and then adding money so both of those options are wrong.

Option 3 shows going up and then going down so that option is wrong.

Option 2 shows taking money only so it is the only correct answer.

Answer:

since they are alternate exteriors, we put a equal sign

2x+78=5x+15

next we subtract 78 on both sides

2x+78-78=5x+15-78

2x=5x-63

then we subtract 5x on both sides

2x-5x=5x-5x-63

-3x=-63

after that we divide -3 on both sides

-3x/-3=-63/-3

and the answer is

x=21

Use the following information to answer the question. The mean age of lead actresses from the top ten grossing movies of 2010 wa

Alex787 [66]

Answer:

You should expect to find about 95% of the lead actresses ages between 16.9 years and 42.3 years.

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 = 29.6 years, Standard deviation = 6.35 years.

Between what two values would you expect to find about 95% of the lead actresses ages

By the Empirical Rule, within 2 standard deviations of the mean. So

29.6 - 2*6.35 = 16.9 years

29.6 + 2*6.35 = 42.3 years

You should expect to find about 95% of the lead actresses ages between 16.9 years and 42.3 years.
