Answer:

See answers below.

Step-by-step explanation:

For formula to find the volume of rectangular prism is given below:

$Volume\:=\:whl$

11. Putting the given values, we have:

$200=\left(2\frac{1}{2}\right)\left(h\right)\left(8\right)\\\\h=10$

$12.\:\:Volume=\left(8\frac{1}{2}\right)\left(4\right)\left(11\right)\\\\Volume = 374$

Draw a picture to show how 2/3 of jakes pizza can be equal to 3/6 of a pizza from als

Harlamova29_29 [7]

2/3 of a pizza is more than half of the pizza.

3/6 = 1/2, so 3/6 of a pizza is exactly half of the pizza.

Given that two pizzas are of different sizes you need to calculate the areas of each pizza and compare them.

Assumming that the two pizzas are circular, you can calculate the area of each pizza from the formula of the area for a circle:

Area of a circle = π * (radius)^2.

Call r the radius of Jake's pizza and R the radius of Al's pizza. Then:

Area of Jake's pizza = π (r^2) and 2/3 of that is: 2π(r^2) / 3.

Area of Al's pizza = π (R^2) and 1/2 of that is π(R^2)/2

So, what you have to do is to use the radius of each pizza, calculate above formulaes and verify whether the results are the same or not.

If f(x) = 2x - 2 and g(x) = x}, what is (gºf)(4)?

Bad White [126]

Answer:

We conclude that:

(gºf)(4) = g(f(4)) = g(6) = 6

Step-by-step explanation:

Given

$f(x) = 2x - 2$

$g(x) = x$

We have to determine (gºf)(4).

(gºf)(4) = g(f(4))

f(4) = 2(4)-2

= 8 - 2

= 6

Thus,

(gºf)(4) = g(f(4)) = g(6) = 6

Therefore, we conclude that:

(gºf)(4) = g(f(4)) = g(6) = 6

Suppose that we have a sample space S5 {E1, E2, E3, E4E4E, E5, E6, E7}, where E1, E2, . . ., E7 denote the sample points. The fo

VashaNatasha [74]

Answer:

P(A) = 0.4 ; P(B) = 0.50 ; P(C) = 0.60 ; P(A u B) = 0.65 ; P(A n B) = 0.25 ;

A and C are mutually exclusive ;

0.5

Step-by-step explanation:

S = {E1, E2, E3, E4, E5, E6, E7}

P(E1) = .05, P(E2) = .20, P(E3) = .20, P(E4) = .25, P(E5) = .15, P(E6) = .10, and P(E7) = .05

Let:

A{E1,E4,E6}

B{E2,E4,E7}

C{E2,E3,E5,E7}

P(A) = 0.05 + 0.25 + 0.10 = 0.40

P(B) = 0.20 + 0.25 + 0.05 = 0.50

P(C) = 0.20 + 0.20 + 0.15 + 0.05 = 0.60

AUB = {E1, E2, E4, E6, E7}

P(A u B) = 0.05 + 0.20 + 0.25 + 0.10 + 0.05 = 0.65

AnB = {E4}

P(A n B) = 0.25

A and C are mutually exclusive if AnC = ∅

A n C = ∅

Hence, A and C are mutually exclusive.

B complement = B' = {E1, E3, E5, E6}

P(B') = 0.05 + 0.20 + 0.15 + 0.10 = 0.5
