100 times rolled total
32 times number 2 was rolled
32/100 chance of rolling a 2 on the number cube
Heads was flipped 55 times, 100 total flips so 55/100
(32/100) x (55/100) = .176
176/1000 x 10 =
1760/10000 A

Answer:

33.49 cubic units

Step-by-step explanation:

V_{sphere}  =  \frac{4}{3}  \times  \pi {r}^{3}  \\  \\ V_{sphere}  =  \frac{4}{3}  \times  \pi {(2)}^{3}  \\  \\  V_{sphere}  =  \frac{4}{3}  \times  \pi  \times 8 \\  \\ V_{sphere}  =  \frac{32 \times 3.14}{3}  \\  \\ V_{sphere}  =  \frac{100.48}{3}  \\  \\ V_{sphere}  = 33.4933333\\  \\ V_{sphere}   \approx 33.49\: units^3

Which ordered pair is the solution to the system of equations?
tiny-mole [99]

Answer:

You can use Gaussian Elimination.

Double both sides of the first equation and add the second equation.

6x + 4y = 8

5x - 4y = 3

---------------

11x      = 11

x = 1

5 - 4y = 3

-4y = -2

y = 1/2

Serjik [45]

Answer:

B. 88.8

Step-by-step explanation:

let x represent class y

(x+71.2)/2=80   multiply each side by 2

x+71.2=160      subtract 71.2 by both sides

x=88.8

or

trial an error

replace x with each of the numbers and see if it plugs in.

example:

(80.5+71.2)/2=80

151.7/2=80

75.85=80?

false. incorrect

another example:

(88.8+71.2)/2=80

160/2=80

80=80?

true. correct
