Answer:
The probability is 0.044
Step-by-step explanation:
Step-by-step explanation:
Let p be the probability that the new principal’s performance is approved.
This is obtainable from the survey and it is 8/10 = 0.8
Let q be the probability that the new principal’s performance is disproved.
That will be;
1 - q = 1- 0.8 = 0.2
To calculate the probability that 14 parents names are chosen at random and they all
approve of the principal’s performance, we use the Bernoulli approximation of the binomial theorem.
That will be;
14C14 * p^14 * q^0
= 1 * 0.8^14 * 0.2^0
= 0.043980465111 which is approximately 0.044
X - 3pt baskets (he reaches 3x points)
y - 2pt baskets (he reaches 2y points)
We know, that y=x+43
97 - 1 free throw = 97 - 1 = 96
Sum of points: 96
3x + 2y = 96. Substitute to "y" an expression "x+43" :
3x + 2(x+43)=96
3x+2x+86=96
5x=10 |:5
x=2
So y=x+43=2+43=45
He has made 2 three points baskets and 45 two points baskets
$35.99 includes 250 'free' minutes. anything over that is $0.2 per minute. So if she used 440 total minutes that means 440 minus 250 free minutes = 190 minutes over. 190 minutes times $0.2/minute = $38 extra
Total = 35.99 + 38 = 73.99
since the area formula is length times width,72 times 36 = 2592 then that times 6 = 15552.That is the area of the lot that has trees.
