Answer:

Range = 7

Mean = 7.75

Assumption: Most students will have 7 or 10 letters in their last name

Step-by-step explanation:

Range = Largest - Smallest

           = 10 - 3

           = 7

Mean = Add the total numbers up to get a total / numbers in the series

          = (3+5+2(6)+2(9)+5(7)+4(8)+5(10)) / (1+1+2+5+4+2+5)

          = 7.75

If the length of a leg of a triangle is 39.2 and the area of the triangle is 63 what is the length of the other leg
Nadya [2.5K]

Answer:

The length of the other leg is 3.21\ units

Step-by-step explanation:

I will assume that the triangle is a right triangle

In a right triangle the legs are perpendicular

so

The area of a right triangle is equal to

A=\frac{1}{2}(a)(b)

where

a and b are the legs of the triangle

In this problem we have

a=39.2\ units

A=63\ units^{2}

substitute the values

63=\frac{1}{2}(39.2)(b)

126=(39.2)(b)

b=126/(39.2)=3.21\ units

umka2103 [35]

Answer:

$930

Step-by-step explanation:

The amount payable at maturity of the loan is simply the sum of the loan amount and the fee charged on the loan.

The loan amount is 890 while the fee charged on the loan is 40. The amount repayable at maturity is thus;

890 + 40 = 930.

Therefore, he has to pay $930 by the time the loan reaches maturity.
