Answer:
15 ft
Step-by-step explanation:
In a parallelogram the diagonals bisects each other
So WC= CY
solve the equation for x
Subtract x from both sides
Now we add 7 on both sides
x=11
Now we need to find CY

Plug in 11 for x

The standard deviation<u> </u><u>INCREASES</u>
Step-by-step explanation:
Standard deviation is used to show how the points of the data deviate from the mean. The formulae for deriving standard deviation is attached. As seen from the formulae, the greater the variance of the data from the mean, the higher the Standard Deviation.
The mean of the given data points is $103.4. $450 is way off from this mean meaning that there is a large variance in this data point.
Answer:
x=1.6 and x=13.4
Step-by-step explanation:
First we must bring -3x over to the left side by addin git the both sides
Answer:
Not possible
Step-by-step explanation:
The only information we are given are the pairs of angles that are congruent which is not enough information to prove that they are congruent
