Answer:

  • Lily is right

Step-by-step explanation:

<u>Carlos made:</u>

  • 12C + 35

<u>Lily made:</u>

  • 12L

<u>Together they made:</u>

  • 12C + 35 + 12L = 12(C + L) + 35

Lily is right. We don't know what 120 means in Carlos's equation, he should put 12L for Lily.

Find the distance between -2 1/2 and -5 3/4 on a number line
Elena-2011 [213]

Answer:

13/4

Step-by-step explanation:

Convert these numbers to a mixed fraction.

-5 3/4 => -23/4

-2 1/2 => -5/2

Make them have a common denominator

-5/2 => -10/4

-23/4 can stay the same.

To find the distance between the two numbers, subtract the lesser value from the greater value.

-23/4 is <u>less</u> than -10/4.

(-10 - (-23)) /4

= 13/4

Therefore the distance between -2 1/2 and -5 3/4 on a number line is 13/4.

lys-0071 [83]

Answer:

The percentage of Millennial students at his college who live in their parents' home is the same as the percentage of Millennials nationwide

Step-by-step explanation:

Given that a  Pew Research analysis stated that in 2012, 36% of the nation's young adults ages 18-31 the so-called Millennial generation - were living in their parents' home.

After reading the analysis, a statistics student wanted to design a study to determine if the percentage was higher for the Millennial students who attend his college.

Hence proper hypotheses would be claiming p = 36% against p >36%

The percentage of Millennial students at his college who live in their parents' home is the same as the percentage of Millennials nationwide

Because null normally we give equal to against alternate.
