Answer:
16(0.5x - 0.75y + 2)
Step-by-step explanation:
16 x 0.5 = 8
16 x -0.75 = -12
16 x 2 = 32
The probability of selecting or choosing seven marbles is 0.29.
Let E be the event of choosing seven red marbles.
According to the given.
Total number of balls in an urn = 13 + 11 = 24
Total number of red marbles = 13
Total number of blue marbles = 12
Now, the total number of ways of selecting 12 marbles from 24 = 
And the number of ways of selecting 7 red marbles = 
As, we know that, the probability of any event can be calculated as by taking the ratio of favroble outcomes to the total number of outcomes.
Therefore, the probability of selecting or choosing seven marbles is given by

⇒ P(E) = 
⇒ P(E) = 792792/2704156
⇒P(E) = 0.29
Hence, the probability of selecting or choosing seven marbles is 0.29.

Answer:
The standard form is 2x^2-4x+5 and the vertex is (1,3)
Answer: it is proportional and the rate of change is $9 per hour
4*9=36
6*9=54
5*9=45
Answer:
This will be the sum of a geometric series where the first term is 4
The common ratio is -5
And we will have 6 terms.....so....the sum is
first term [ 1 - common ratio^number of terms ] / [ 1 - common ratio ] =
4 [1 - (-5)^6] / [ 1 - -5 ] =
4 [ 1 - 15625 ] / 6 =
(2/3) ( -15624 ) =
-10416
