Answer:
12
Step-by-step explanation:
AC = BD (as the diagonal of the rectangle)
4x-60=30-x
4x+x = 30+60
5x = 90
x = 90/5
x = 18
=> BD = 30-18 = 12
77, 80, 87, 88, 92, 94, 99
the median is 88
Q1 is 80 and Q3 is 94
94-80 = 14 which is the interquartile range
therefore, your answer is D) 14
Straight line equation has a general form of

Where m is the slope

and c is the y intercepted part.
So now, you need to find the value of the slope (m) and the y intercept (c).
As you can notice the line intercepts with y axis in (0,1) So c=1.
And then you want to find 2 points along that line to found the slope from, we found on already (0,1) and the other one can be any point along the line, let's take (2,3).
Then use them to find the slope.

So now
m=1 and c=1.
The equation of this line is y=x+1
Hope this helps!

Answer:
With monthly compounding, the bank will calculate interest on your account just once per month. It will not update your balance on a daily basis when it calculates how much interest it owes you. Assuming that the APR is the same, accounts with monthly compounding offer a lower APY than accounts with daily compounding.
