Answer:
81.24%
Step-by-step explanation:
First we solve for the variance
Sample space of
3,5,12,3,2
n = 5
Variance = s²
= (3-5)²+(5-5)²+(12-5)²+(3-5)²+(2-5)²/5-1
= 4+0+49+4+9/4
S² = 66/4
= 16.5
Secondly we find the standard deviation
= √16.5
= 4.062
Coefficient of variation
Cv = sd/mean x 100
= 4.062/5 x 100
= 406.2/5
= 81.24%
Answer: 19 boys and 14 girls liked the Giants.
Step-by-step explanation:
Let be "b" the number of boys who liked the Giants and "g" the number of girls who liked the Giants.
Based on the information given, set up a system of equations:
![\left \{ {{b+g=33} \atop {b=g+5}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7Bb%2Bg%3D33%7D%20%5Catop%20%7Bb%3Dg%2B5%7D%7D%20%5Cright.)
Use the Substitution method to solve this system of equations.
First, you must substitute the second equation in the first equation and solve for "g":
![(g+5)+g=33\\\\2g=33-5\\\\g=\frac{28}{2}\\\\g=14](https://tex.z-dn.net/?f=%28g%2B5%29%2Bg%3D33%5C%5C%5C%5C2g%3D33-5%5C%5C%5C%5Cg%3D%5Cfrac%7B28%7D%7B2%7D%5C%5C%5C%5Cg%3D14)
<em> </em>And finally, you must substitute the value of "g" into the second equation in order to find the value of "b".
Then:
![b=(14)+5\\\\b=19](https://tex.z-dn.net/?f=b%3D%2814%29%2B5%5C%5C%5C%5Cb%3D19)
<h3>
Answer: 1.75 square feet</h3>
This converts to the improper fraction 7/4
======================================================
Work Shown:
3/4 = 0.75
area of triangle on the left = base*height/2 = 0.75*2/2 = 0.75 sq ft
area of triangle on the right = base*height/2 = 1*2/2 = 1 sq ft
total area = 0.75+1 = 1.75 sq ft
This converts to the improper fraction 7/4 because
1.75 = 1 + 0.75
1.75 = 1 + 3/4
1.75 = 4/4 + 3/4
1.75 = (4+3)/4
1.75 = 7/4
14.0305 rounded to the nearest hundredth place is 14.03
First, identify the hundredths digit: the 3 in 14.0305
Next, identify if the next digit is greater than 5.
That digit is not greater than or equal to 5 so you would round down.
