Answer:
232
Step-by-step explanation:
all u gotta do here is plug in 40 here so:
0.145(40)x^2
0.145(1600)
f(x)= 232
The answer would be number 1. 173 units^2
Based on the data, the most likely correlation coefficient would be -1.
The slope between 20 and 30 days is -1, and it represents the change in the surface area of the lake per day.
The data represents correlation, not causation.
Since the data would form a perfectly straight line through the points, the correlation coefficient would be -1 for a perfect decreasing fit.
To find the slope, find the change in the surface area between those days, the change in the days, and write it as surface area/days: 80-90=-10; 30-20=10; -10/10=-1
This is not causation because there could be lurking variables we cannot see.
The total amount to be repaid is equal to $949.66
Step-by-step explanation:
Simple interest is a type of interest that is usually applied on short term loans, where when a payment is made towards this kind of interest the payment first goes towards monthly interest, and then the remainder is reverted towards the principal.
FORMULA FOR CALCULATING SIMPLE INTEREST =
Here principal = $922
interest rate = 6%
time period = 6 months (when made per annum it will be 6/12)
SIMPLE INTEREST IS EQUAL TO $27.66
The total amount that is to be repaid is equal to
PRINCIPAL + SIMPLE INTEREST
= $922 + $27.66
= $949.66
