Answer:

a. 0.308 = 30.8% probability that a red ball is drawn.

b. 0.816 = 81.6% probability that the ball drawn is not white.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

308 + 184 + 508 = 1000 balls

a.A red ball is drawn

308 balls are red. So

308/1000 = 0.308

0.308 = 30.8% probability that a red ball is drawn.

b.the ball drawn is not white.​

1000 - 184 = 816 are not white.

816/1000 = 0.816

0.816 = 81.6% probability that the ball drawn is not white.

The owner of an orange grove estimates that if 24 trees are planted per acre, then each mature tree will yield 600 oranges per y
tia_tia [17]

Answer:

16428 oranges

Explanation:

Total yield = number of trees × number of oranges in each tree

Initial yield = 600×24= 14400 oranges

To find the equation needed, let x = additional trees and y= total yield

Number of trees = 24 +x

Number of oranges in each tree = 600-12x

Equation of total yield y= (24+x)(600-12x)

y= 14400-288x+600x-12x²

y= -12x²+312x+14400

Using a graphing calculator, from the graph drawn for this quadratic equation, we notice that it is a parabola. Therefore to find the maximum value, we should find the maximum point which is at the vertex of the parabola, we use the formula x= -b/2a

A quadratic equation is such: ax²+bx+c

Therefore x =-312/2×-12

x= -312/-24

x= 13

So we can conclude that in order to maximise oranges from the trees, the person needs to plant an additional 13 trees. Substituting from the above:

24+x=24+13= 37 trees in total

y= -12x²+312x+14400= -12×13²+312×13+14400= -2028+4056+14400

=16428 oranges in total yield
