80,000 - 30,000 = 50,000
50,000 / 80,000 = .625
62.50%

A toy box contains eight green balls and four purple balls. Suppose you choose a ball at random and then replace it by putting i

dedylja [7]

Answer: C. $\dfrac{1}{3}$

Step-by-step explanation:

Given: Box contains 8 green balls and 4 purple balls.

Total balls = 8+4 = 12

event 1 = first picking green ball

event 2 = second picking purple balls.

As first ball was replaced, that means both events are independent.

Probability that you have selected a green ball and then a purple ball = P(purple ball )

Formula for probability = $\dfrac{\text{favorable outcomes}}{\text{total outcomes}}$

Probability of selecting a purple ball (second pick)= $\dfrac{4}{12}$

$=\dfrac{1}{3}$

The required probability $=\dfrac{1}{3}$ , so C is correct option.

(7,3)
(-2,-5)

Distance:-

$\\ \rm\Rrightarrow \sqrt{(7+2)^2+(3+5)^2}$

$\\ \rm\Rrightarrow \sqrt{9^2+8^2}$

$\\ \rm\Rrightarrow \sqrt{81+64}]/tex][tex]\\ \rm\Rrightarrow \sqrt{145}$

$\\ \rm\Rrightarrow 12(approx)$

Midpoint

$\\ \rm\Rrightarrow \left(\dfrac{7-2}{2},\dfrac{3-5}{2}\right)$

$\\ \rm\Rrightarrow \left(\dfrac{5}{2},\dfrac{-2}{2}\right)$

The question of two numbers is eight the sum of the same two numbers is 72 what are the two numbers

Otrada [13]

Answer:

The two numbers are 64 and 8.

Step-by-step explanation:

You meant "quotient" of two numbers, right?

Represent the numbers by x and y.

Then the quotient is x/y = 8, and beyond that we know that x + y = 72.

Solve this for x and y.

If x/y = 8, then x = 8y. Substituting this into x + y = 72, we get:

(8y) + y = 72, or 9y = 72. Dividing both sides by 9 yields y = 8.

Since x/y = 8, letting y = 8 results in x = 64.

The two numbers are 64 and 8.
