1st order the data point from smaller to greater:
x = 25,31,46,52,55,67 (n=number of data points = 6)
2nd Add them up = 25+31+46+52+55+67 = 276
3rd : find the mean 276/5 = 46 = mean
4th make (x- mean)² for each x. EXAMPLE:
25-46 = -21 →→(-21)² = 441
31-46 = -15→→(-15)² = 225
AND SO ON AND SO FORTH. Then add all squared together you will get:
∑(x-mean)² = 1224
variance = ∑(x-mean)²/(n-1) = 1224-5 = 1219
Answer:
tHERE ARE NO EQUATIONS
Step-by-step explanation:
60% of 25
= 60/100 x 25
= 0.6 x 25
= 15
Answer:
d. 11
Step-by-step explanation:
The outlier is D. 11 because it is the furthest amount from any other set.
The formula for simple interest is: Total amount = Principal ( loan amount) x (1 + interest rate x time (years).
Using the given information you have:
Total = 7540 x (1 + 0.065 x 2.5)
Total = 7540 x (1 + 0.1625)
Total = 7540 x 1.1625
Total = $8,765.25
Answer:
B.
Step-by-step explanation:
It is just common sense. The top numbers have to be smaller than the top numbers
