Answer:
Standard deviation = 5.1
Mean = 13
Median = 14
Step-by-step explanation:
The sample standard deviation measures the spread of a data distribution of the sample. It is usually used to estimate the population standard deviation
The mean of a set of numbers is the sum divided by the number of terms.
Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
Answer:
6 hours
Step-by-step explanation:
What you have to do is find the unit rate, which would be 20/40 which is .5 ( half an hour, 30 mins ) . Then you would do 30 x 12 = 360 ( 6 hours ).
Answer
Their combined score is 331 points
Explanation
Determine each person's score
Collin score: 139
Brian: 139 + 53 = 192
Add the scores together
139 + 192 = 331
Answer:
22
Step-by-step explanation:
What you need to do to find the base is divide the area by the height, which would be 330/15! Hope this helps! :)
Answer:
solve for x
4x-6=26
4x=26+6
x=32/4
x=8
area of rectangle=l*b
=26*14
=364
area of triangle=b*h/2
=18.4*20.4/2
=375.36/2
=187.68 m^2
for another side of a triangle
(18.4)^2+(20.4)^2=c^2
338.56+416.16=c^2
=c
27.47=c
27.5=c
now, perimeter of triangle=a+b+c
=27.5+18.4+20.4
=66.3 m^2
radius=diameter/2
=26/2
=13 ft
diameter=26 ft
circumference=2πr
=2*3.14*13
=81.64
Area of a circle=π
=3.14*(13)^2
=3.14*169
=530.66 ft^2
