Answer:

  • Zero

Step-by-step explanation:

Step 1. Find the mean

  • (- 9 - 18 - 16 - 13 - 14)/5 = - 14

Step 2. Find the deviation of each value from the mean

  • - 9 - (- 14) = 5
  • - 18 - (- 14) = - 4
  • - 16 - (- 14) = - 2
  • - 13 - (- 14) = 1
  • - 14 - (- 14) = 0

Step 3. Find the sum of the deviations

  • 5 - 4 - 2 + 1 + 0 = 0

Step 4. Find the MAD

  • 0/5 = 0

If $2940 is invested at 3.2% compounded quarterly, how much is in the account after 8 years?
tino4ka555 [31]

Answer:

The future value is $3793.776

Step-by-step explanation:

Given

PV = 2940 --- present value

r = 3.2\% --- rate

t = 8 --- time

n = 4 --- quarterly

Required

Determine the future value

This is calculated using:

FV = PV(1 + \frac{r}{n})^{nt

So, we have:

FV =2940 * (1 + \frac{3.2\%}{4})^{4*8

FV =2940 * (1 + \frac{3.2}{400})^{32

FV =2940 * (1 + 0.008)^{32

FV =2940 * (1.008)^{32

FV =2940 * 1.2904

FV =3793.776

HELPPPPPPPPPPPPPPPPPPP!!!
Angelina_Jolie [31]

Answer:

15.13cm

Step-by-step explanation:

From that above question:

We are told that:

Lateral surface area of a right circular cone : πr√r² + h²

We are give the following parameters:

Lateral surface area = 236.64cm²

Radius = 4.75cm

We are to find the height

Making h the subject of the formula

h = √[(A/r)² - πr²]/π

h = √[(236.64/4.75)²- π ×4.75²]/π

h = 15.12975 cm

Approximately to the nearest hundredth = 15.13cm

VERY URGENT.
NemiM [27]

Answer:

(1)Base Area= 81 square yards.

(2)

  • 3 ft long and 16 ft wide
  • 6 ft long and 8 ft wide
  • 24 ft long and 2 ft wide

(3)Height=12 Units

Step-by-step explanation:

<u>Question 1</u>

Volume of the rectangular prism=2,592 cubic yards.

Height of the rectangular prism=32 yards

Volume of a rectangular prism =lbh (where lb is the Base Area)

Therefore:

lbh=2592

32lb=2592

lb=2592/32=81

Base Area= 81 square yards.

<u>Question 2</u>

Volume of the rectangular prism=432 cubic feet.

Height of the rectangular prism=9 feet

Volume of a rectangular prism =lbh (where lb is the Base Area)

Therefore:

lbh=432

9lb=432

lb=432/9=48

Base Area= 48 square yards.

Any dimension whose product is 48 is a possible choice.

They are:

  • 3 ft long and 16 ft wide
  • 6 ft long and 8 ft wide
  • 24 ft long and 2 ft wide

<u>Question 3</u>

<u />

Volume of the rectangular prism=960 cubic units.

Base Area of the rectangular prism, lb=80 Square Units

Volume of a rectangular prism =lbh (where lb is the Base Area)

Therefore:

lbh=960

80h=960

h=960/80=12

Height= 12 units.
