Answer:

Option B. False

Step-by-step explanation:

If we take set of whole numbers as 1, 2, 3, 4, 5, 6.

Then the median of this set will be mean of two whole numbers which are in center.

Median = (3 + 4)/2 = 7/2 = 3.5

which is not a whole number.

Therefore the given statement that median of a list of whole numbers must be a whole number is False.

Answer is False.

Answer:

$x=5/2, x=-3\\$

Step-by-step explanation:

$x(2x+6)=5(x+3)\\2x^2+6x=5x+15\\2x^2+6x-5x-15=0\\2x^2+x-15=0\\2x^2+6x-5x-15=0\\2x(x+3)-5(x+3)=0\\(2x-5)(x+3)=0\\2x-5=0, x+3=0\\x=5/2, x=-3\\$

Answer:

Rate = 13.173% per year

Step-by-step explanation:

**Not 100% sure about this answer, but I think it's right.**

Calculation Steps:

Solving for rate r as a decimal

r = n[(A/P)^1/^nt - 1]

r = 1 × [(668.00/359.80)^1/^(1)^(5) - 1]

r = 0.131731

Then convert r to R as a percentage

R = r * 100

R = 0.131731 * 100

R = 13.173%/year

Answer:

$\large\boxed{S.A.=1,000\ u^2}$

Step-by-step explanation:

We have two congruent right triangles and three rectangles.

First, calculate the length of the hypotenuse using the Pythagorean theorem:

$leg^2+leg^2=hypotenuse^2$

We have

$leg=8,\ leg=15,\ hypotenuse=h$

Substitute:

$h^2=8^2+15^2\\\\h^2=64+225\\\\h^2=289\to h=\sqrt{289}\\\\h=17$

The formula of an area of a right triangle:

$A_t=\dfrac{(leg)(leg)}{2}$

Substitute:

$A_t=\dfrac{(8)(15)}{2}=(4)(15)=60$

The formula of an area of a rectangle:

$A=wl$

w - width

l - length

Rectangle 1:

w = 15, l = 22

$A_1=(15)(22)=330$

Rectangle 2:

w = 17, l = 22

$A_2=(17)(22)=374$

Rectangle 3:

w = 8, l = 22

$A_3=(8)(22)=176$

The Surface Area of the triangular prism:

$S.A.=2A_t+A_1+A_2+A_3$

Substitute:

$S.A.=2(60)+330+374+176=1,000$
