Answer:
16 pies
Three-Quarters of 16 is 12, and if you sell 12, then you have a quarter which is 4, which ends up being every quarter which equaled 4
Using the binomial probability relation, the probability that exactly 27 graduates earn a college degree is 0.069
<u>Using the relation</u> :
<em>P(x = x) = nCx * p^x * q^(n-x) </em>
- Probability of success, p = 0.15
- q = 1 - p = 1 - 0.15 = 0.85
- Number of trials, n = 200
- X = 27
<u>Probability of exactly 27 graduates can be defined thus</u> :
P(x = 27) = 200C27 × 0.15^27 × 0.85^173
P(x = 27) = 0.0686264
Therefore, the probability of selecting <em>exactly 27 graduates</em> is 0.069

Step-by-step explanation:
3
Answer:
no solutions
Step-by-step explanation:
Given the 2 equations
y = 2x - 1 → (1)
y = 2x + 6 → (2)
Substitute y = 2x - 1 into (2)
2x - 1 = 2x + 6 ( subtract 2x from both sides )
2x - 2x - 1 = 6 ( add 1 to both sides )
0 = 7 ← not possible
Thus the system has no solution
