3 0

Answer: 45 and 3/8

Step-by-step explanation:

8 and 1/4 = 8.25

8.25/d = 2/11

Multiply 2 x d and 8.25 x 11

2d = 90.75

Divide 90.75 by 2 = 45.375

.375 = 3/8

​ a(1)= 3 5 ​ a(n)=a(n−1)⋅(−9) ​ What is the 3^{\text{rd}}3 rd 3, start superscript, start text, r, d, end text, end superscript
frosja888 [35]

Answer: -630

Step-by-step explanation:

Given the nth term of a sequence;

​a(n)=a(n−1)⋅(−9) and the first term of the sequence a(1) as 35, the third term of the sequence can be gotten by using the formula at when n = 3

If n = 3 and a(1) = 35;

a(3) = 35(3-1)•(-9)

a(3) = 35×2×-9

a(3) = 70×-9

a(3) = -630

There the 3rd term of the series will give us -630 according to the nth term of the formula given.

An investment strategy has an expected return of 15 percent and a standard deviation of 9 percent. Assume investment returns are
IgorLugansk [536]

Answer:

68% of an investment earning a return between 6 percent and 24 percent.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 15

Standard deviation = 9

How likely is it to earn a return between 6 percent and 24 percent?

6 = 15 - 1*9

6 is one standard deviation below the mean

24 = 15 + 1*9

24 is one standard deviation above the mean

By the empirical rule, there is a 68% of an investment earning a return between 6 percent and 24 percent.

You solved a linear system with two equations and two variables and got the equation o=-8. how many solutions does the system of
Luda [366]
If you simplified a two-equation system and all variables were eliminated, two outcomes are possible.

If the final equation is a true equation, like 3=3, then the system has an <em>infinite number of solutions </em> (the equations graph the same line, and all points appear on both graphs)

If the final solution is a mathematically false equation, like 0=-8, the system has no solution. The lines are parallel and never intersect (have a solution)
