The mean of a data set is equal to 10 and its standard deviation is equal to 1. If we add 5 to each data value, then the mean an
andrey2020 [161]
Let
S = sum of the data values
n = number of data values

The mean M is equal to 
M = S/n
since you add up the values and divide by n. We don't need to know what S or n are. 

If we add 5 to each data value, then we're adding on n copies of 5, or 5n

The new mean N is

N = (S+5n)/(n)
N = (S/n) + (5n/n)
N = M + 5

The new mean is a result of taking the old mean M and adding on 5

So,
N = M+5
N = 10+5
N = 15

The standard deviation will remain the same because each data value hasn't moved in relation to one another. Every data value has been shifted up the same amount. For instance if A and B are two points in this data set, then A+5 and B+5 will be the same distance away. Apply this logic to any number of data values. While standard deviation isn't that simple, it still has a loose connection to "distance" of the values, or how spread out they are. 


So that's why the final answer is choice C)

A rectangular swimming pool measures 14 feet by 30 feet. The pool is
Zolol [24]

Answer:

The total cost of resurface the path is \$600

Step-by-step explanation:

step 1

Find the area of the path

The area of the path is equal to the area of the path plus the swimming pool minus the area of the swimming pool

A=(14+3+3)(30+3+3)-(14)(30)

A=(20)(36)-(14)(30)

A=300\ ft^{2}

step 2

Find the cost of resurface the path

Multiply the area of the path by $2 per square foot

300*2=\$600
