Students reported volunteering at the animal shelter during the last 6 months for 25, 36, 31, and 32 hours. What is the mean absolute deviation for the number of hours students volunteered? Round to the nearest tenth.0
3
4
6

Answers

Answer 1

Answer: The correct answer for the question that is being presented above is this one: "3"

(1) First get the mean: 25 + 36+ 31 + 32 / 4 = 31
(2) Find the distance of each value to the mean: 31-25= 6; 36-31=5; 31-31=0; 32-31=1
(3) Get the mean of the distance: 6 + 5 + 0 + 1 / 4 = 3

So the mean deviation is 3.

Cross Multiplication!
$(4)/(7)$ = $(x-3)/(21)$
4 × 21 = 7 × (x-3)
Distribute 7 into the parenthesis:
84 = 7x - 21
Take 21 to the other side:
84 + 21 = 7x
105 = 7x
Divide by 7 on both sides:
$(105)/(7)$ = $(7x)/(7)$
( 7 and 7 cancels out )

BEST ANSWER GETS A METAL!!!!Which pair of complex numbers has a real-number product?

(1 + 3i)(6i)
(1 + 3i)(2 – 3i)
(1 + 3i)(1 – 3i)
(1 + 3i)(3i)

Answers

we will proceed to verify each case to determine the solution

remember that

$i^(2) =-1$

case A) $(1 + 3i)(6i)$

applying distributive property

$(1 + 3i)(6i)=1*6i+3i*6i \n=6i+18i^(2)\n=6i+18*(-1)\n=6i-18$

$-18+6i$ ------> is not a real number

therefore

the case A) is not a real number product

case B) $(1 + 3i)(2-3i)$

applying distributive property

$(1 + 3i)(2-3i)=1*2+1*(-3i)+3i*(2)+3i*(-3i)\n=2-3i+6i-9i^(2)\n=2+3i-9*(-1) \n=11+3i$

$11+3i$ ------> is not a real number

therefore

the case B) is not a real number product

case C) $(1 + 3i)(1-3i)$

applying difference of square

$(1 + 3i)(1-3i)=(1)^(2)-(3i)^(2)\n=1-9i^(2)\n=1-9*(-1) \n=10$

$10$ ------> is a real number

therefore

the case C) is a real number product

case D) $(1 + 3i)(3i)$

applying distributive property

$(1 + 3i)(3i)=1*3i+3i*3i \n=3i+9i^(2)\n=3i+9*(-1) \n=3i-9$

$-9+3i$ ------> is not a real number

therefore

the case D) is not a real number product

the answer is

$(1 + 3i)(1-3i)$

The answer is (1 + 3i)(1 – 3i).

True or false questions basic math1.the total surface area of a cube each of whose edges is 12 inches long is 6 square feet

2.if the tank in a car holds 15 gallons of gasoline, the volume of the tank is one cubic foot

3.two cones have equal height. if the base of one cone is a circle and the base of the other cone is a square, the two cones cannot have equal volumes

4.the diameter of the moon is approximately one-fourth the diameter of earth, hence the volume of the moon is one-fourth the volume of earth.

each of these questions are true or false.. could use the help tonight please

Answers

Answer:

1. True

2. False

3. False

4. False

Step-by-step explanation:

1. It is true because12 inch is equal to 1 feet, so the area of each side of the cube is 1 square feet, adding the 6 sides of the cube you have a surface area of 6 square feet.

2. It is false because 7.5 gallons is equal to 1 cubic foot.

3. It is true because both cones have equal height but the fact that the bases are different make the volume different.

4. Is false because when you calculate the volume of a sphere you have to raise the radius (half the diameter) to the cube, so there is not a direct relation.

1. False
2. False
3. True
4. False

and #3 if you think about it is kind of a trick question. If the base of the "cone" is a square than its not a cone to begin with. It would be a square pyramid.
