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%
Answer:
The answer to your question is: 29 tickets for children and 58 tickets for men.
Step-by-step explanation:
Child = c = $ 5.50
Adult = a = $8.80
Equation
a = 2c
5.5c + 8.8a = 669.9
5.5c + 8.8(2c) = 669.9
5.5c + 17.6c = 669.9
23.1c = 669.9
c = 669.9 / 23.1
c = 29
a = 2(29)
a = 58
Answer:
I think it's by mantaining the warm temperatures required for the life on the Earth
A ) This is a quadratic function:
y = a x² + b x + c
If the starting point is ( 0, 0 ) then c = 0
b ) The function is:
y = - 0.2 x² + 3.6 x
( with coefficients to the nearest tenth )
The graph is in the attachment.
c ) The roots:
x 1 = 0,
0.2 x = 3.6
x = 3.6 : 0.2
x 2 = 18d ) This is near the target ( 17 m ) . So the pumpkin
will hit near the target.
