Answer:
see explanation
Step-by-step explanation:
The solution to the equations is at the point of intersection of the 2 lines.
If the system has no solution, this indicates the lines do not intersect and therefore must be parallel.
This problem can be solved by using the binomial distribution.
p = 30% = 0.3 is the probability that a teacher was laid off.
q = 1 -p = 0.7 is the probability that a teacher was not laid off.
n = 16 is the sample size.
r = 7 is the expected number of teachers who were laid off
The probability that 7 out of 16 teachers were laid off is
₁₆C₇ p⁷q⁽¹⁶⁻⁷⁾ = 11440*(0.3⁷)*(0.7⁹) = 0.101 =10.1%
Answer:
The probability is 0.101 or 10.1%
C + p = 10 . . . . . . . . . . . . . . . .the grocer wants 10 lbs of mix
6.50c +4.00p = 4.75*10 . . . . . the total cost of the mix is the sum of costs of contributors to the mix
Find each probability separately and then multiply the two together
Probability for even number is 3/6 or 1/2 because their are 3 even numbers out of 6 numbers
Probability to get a black chip is 1 black chip out of 3 totals so 1/3
Multiply 1/3 by 1/2
Answer 1/6
I think the answer is 1 over 2 (0.5), thats if i understand what you’re saying
