Answer:

The combined expenses in Years 3 and 4 were $300,000 more than the combined income of Years 3 and 4.

Step-by-step explanation:

The combined income in years 1, 2, and 3 is $1,400,000 and the combined expenses in the same years is $1,500,000; so number 1 is incorrect.

Expenses have increased $100,000 each year over the last 5 years. Year 1 = $400,000 , Year 2 = $500,000 , Year 3 = $600,000 , Year 4 = $700,000 , Year 5 = $800,000. So number 3 is incorrect.

Year 1's income was $600,000 and Year 5's income was $900,000. Twice Year 1's income would have been $1,200,000. So number 4 is incorrect.

Answer:

B.

Step-by-step explanation:

A.

Income: 600,000 + 600,000 + 400,000 =

$1,600,000

Expenses: 400,000 + 500,000 + 600,000 =

$1,500,000

B .

Expenses: 600,000 + 700,000 =

$1,300,000

Income: 400,000 + 600,000 =

$1,000,000

1,300,000 - 1,000,000 = $300,000

C.

Expenses:

Year 1: 400,000

+ 100,000 =

Year 2: 500,000

+ 100,000 =

Year 3: 600,000

+ 100,000 =

Year 4: 700,000

+ 100,000 =

Year 5: 800, 000

Adds 100,000 each year not 200,000.

D.

Income:

Year 1: 600,000 x 2 =

$1,200,000

Year 5:

$900,000

solve the average time for a student to complete this quiz is 24 24 minutes with a standard deviation of 2 minutes. What is the
LuckyWell [14K]

Answer:

The correct answer is "(18, 30) minutes".

Step-by-step explanation:

Mean,

= 24

Standard deviation,

= 2

The range of minutes where 99.7% of individuals completed the quiz will be:

= Mean \pm 3\times Stdev

On substituting the values, we get

= 24 \pm 3\times 2

= 24 \pm 6

now,

= 24-6

= 18

Or,

= 24+6

= 30

i.e., 18 to 30 minutes
