How can I create a word problem with the following expressions <br><br> 15+2d<br><br> 200-4m
Alenkasestr [34]
For the first expression
15 + 2d
A possible word problem would be this:
A person saves $2 per day of money. Before he started saving, he had $15 dollars set aside. Look for the expression that expresses the total amount of money saved in terms of the number of days passed

The second expression is
200 - 2m
A possible word problem would be this:
The distance from school to the park is 200m. A kid riding a bike is traveling at a speed of 2m/s from the school to the park. Write an expression for the distance remaining between the park and the kid.<span />

. What are the exact solutions of x2 - x - 4 = 0?
Dimas [21]
X ² - x - 4 = 0
x_{1}  = \frac{1+ \sqrt{1+16}  }{2}= \frac{1+ \sqrt{17} }{2} = 2.56
x_{2} =  \frac{1- \sqrt{17} }{2}= - 1.56
Exact values are x 1 = 2.56 and x 2 = -1.56

Living with parents: The Pew Research Center reported that 36% of American Millennials (adults ages 18-31) stll live at home wit
Lera25 [3.4K]

Answer:

A.

\mathbf{The \  sample \  comes  \ from \  a \  population \ of \ Millennial \ students } \mathbf{at \  their \ campus\ where \ 3 6\%\ still\ live\ at\ home\ with\ their \  parents}

Step-by-step explanation:

From the given information.

The proportion of American Millennials still with their parents = 0.36

The sample size  = 300

Sample proportion = 0.43

Level of significance = 0.006

P-value = 0.006

Null hypothesis:

\mathbf{H_o: Of  \ Millennial \ students  \ at \ their \ campus, \ 36\% \  }\mathbf{ live \ at \  some  \ with  \ their \  parents . }

\mathbf{H_a: More \ than \ 36\%  \ of  \ Millennial \ students  \ at \ their \ campus \ live \ at \ home }\mathbf{ \ with \ their \ parents}

The required task is to determine the assumption about the sample that underlies the hypothesis test from the given options.

A.

\mathbf{The \  sample \  comes  \ from \  a \  population \ of \ Millennial \ students } \mathbf{at \  their \ campus\ where \ 3 6\%\ still\ live\ at\ home\ with\ their \  parents}

This is because the student wants to check if the null hypothesis ( which states that of Millennial students at their campus, 36% live at home with their parents) is correct or not.
