Answer:

The arithmetic average return would be 3.96%

Step-by-step explanation:

Given,

The returns in 5 years are,

-​9.7%, -​8.1%, ​15%, 7.2%, and​ 15.4%

We know that,

\text{Arithmetic average}=\frac{\text{Sum of all observations}}{\text{Number of observations}}

Hence,

The arithmetic average return of the investment = \frac{-9.7-8.1+15+7.2+15.4}{5}

=\frac{19.8}{5}

= 3.96%

Answer: Choice C)

We start at 0 and move 1.4 units to the right. Then we move another 2.3 units to the right to land on 3.7

Notice how 1.4 - (-2.3) = 1.4 + 2.3 = 3.7

The Nut House sells peanuts for $6.75 per pound and cashews for $9.50 per pound. On Saturday, they sold 32 pounds more peanuts t
Ber [7]

Answer:

81 pounds

Step-by-step explanation:

Given that:

Peanut per pound = $6.75

Cashew per pound = $9.50

Let

Number of cashews sold = x

Number of peanuts sold = x + 32

Total sales made = $1,012.25

(Number of caahew sold * cost of cahew) + (Number of peanut sold * cost of peanut) = total sales made

(x * 9.50) + [(x + 32) * 6.75)] = 1012.25

9.50x + 6.75x + 216 = 1012.25

16.25x = 796.25

x = 796.25 / 16.25

x = 49

Number of peanuts sold = x + 32 = 49 + 32 = 81

1/x+3=x+10/x-2 From least to greatest, the solutions are x= and x=<br><br>PLEASE HELP!​
Arturiano [62]

Answer:

x = -8 and x = -4.

Step-by-step explanation:

1/(x + 3) = (x + 10)/(x - 2)

1 * (x - 2) = (x + 10) * (x + 3)

x - 2 = x^2 + 3x + 10x + 30

0 = x^2 + 13x + 30 - x + 2

0 =  x^2 + 12x + 32

0 = (x + 8) * (x + 4)

1. x = -8

2. x = -4

The correct result would be x = -8 and x = -4.

hope this helped

a girl wants to count the steps of a moving escalator which is going up. if she is going up on it, she counts 60 steps. if she i
Leto [7]

Let

x--------> the speed of the girl in step

y--------> the speed of the escalator in step

d------> the distance between ground and floor.

we know that

speed=\frac{distance}{time} \\ \\ time=\frac{distance}{speed}

when the girl is going up on escalator

x-y=\frac{d}{60} ----> equation 1

when the girl is going down on escalator

x+y=\frac{d}{90} -------> equation 2

Adds equation 1 and equation 2

2x=\frac{d}{60} +\frac{d}{90} \\ \\ 2x=\frac{5}{180} d

x=\frac{5}{360}d --------> equation 3

Time to climb (in step) with y=0 (escalator standing still)

x*t=d\\\\ t=\frac{d}{x} -----> equation 4

Substitute equation 3 in equation 4

t=\frac{d}{\frac{5d}{360}}  \\ \\ t=\frac{360}{5} \\ \\ t=72 steps

therefore

the answer is

72 steps
