Answer 1
Answer:

Following are the calculation of cups of sugar:

Given:

1 (1)/(4) cups sugar makes 20cookies

To find:

calculate cups of sugar in making 14 cookies.

Solution:

1 (1)/(4) cups sugar makes 20cookies

Which applies:

\to (5)/(4)cups sugar makes 20 cookies

For 14 cookies calculating the total cups:

Assuming the cups of sugar=x

then

\to x=(((5)/(4))* 14) / 20\n\n\to x=((70)/(4)) / 20\n\n\to x=( 17.5) / 20\n\n\to x=(17.5)/(20)\n\n\to x= 0.875

Therefore, the final answer is "0.875".

100 students take a course pass/fail. If they pass they get 4 points towards their GPA, if they fail they get 0. If 90 students pass, what is the mean and standard deviation (to 1 decimal) of the points earned?Mean: ________a0

Standard Deviation:________ a1

Answers

Formulas
Mean = total sum of points / # of data
[Stantard deviation] ^ 2 = {Sum of [every data - mean]^2 } / [number of data - 1]

Procedure:

Mean = total sum of points / # of data

Total sum of points = point of pass + point of fail

points of pass = 90*4 = 360
point of fail = 10*0 = 0
Total sum of points = 360

Number of data = 100

Mean = 360/100 = 3.6

[Stantard deviation] ^ 2 = {Sum of [every data - mean]^2 } / [number of data - 1]

[Sum of every data - mean]^2  = 90*[4 -3.6]^2 + 10* [0 - 3.6]^2 = 14.4 + 129.6 = 144

 [Stantard deviation] ^ 2 = [144]/[100-1] =144/99

Standar deviation = √(144/99) = 1.206
