Answer:
16.2
Step-by-step explanation:
r = k/x
72 = k/9
k = 72*9
When r = 40 ,
x = k/r
x = 72*9/40 = 16.2
Answer:
f(x) = 16x2 + 32x - 9
To find the "zeros", set f(x) = 0:
0 = 16x2 + 32x - 9
The equation is solvable by factoring or by using the quadratic formula. The factors (use the "ac" method) are:
0 = (4x-1)(4x+9)
x = 1/4 = 0.25 and x = -9/4 = -2.25
Step-by-step explanation:
Answer: A.) Probability is approximately 5%
B.) probability that Die1 + Die + Die > 12 is approximately 26%
Step-by-step explanation:
Total possible outcomes of the three dies (sample space) = (6^3) = 216
For die1 + die2 + die3 to be equal six, then the number of outcomes which produces our required outcome from the sample space is = 6
Therefore, probability of die1 + die2 + die3 = 6 is given by;
P(die1 + die2 + die3 = 6) = total required outcome / total possible outcomes
P(die1 + die2 + die3 = 6) = 10/216
P( die1 + die2 + die3 = 6) = 0.04629
P( die1 + die2 + die3 = 6) = 4.63% approximately 5%
B) probability that Die1 + Die + Die > 12
P(Die1 + Die + Die > 12) = 57/216 = 0.2638
= 26.38%
Approximately 26%
