Answer:
$124200
Step-by-step explanation:
Find the total hours worked by each employee: 8 * 5 = 40
$30 an hour people: 98 -11 = 87
Amount of money $30 an hour people each make: 30 * 40 = 1200
Amount of money $45 an hour people each make: 45 * 40 = 1800
$30 in total: 1200 * 87 = 104400
$40 in total: 1800 * 11 = 19800
All in total: 104400 + 19800 = 124200
Given that the vertex of the parabola is (4,-3)
The parabola passes through the point (2,-1)
We need to determine the standard form of the equation of the parabola.
<u>Standard form of the equation of the parabola:</u>
The standard form of the equation is
where the vertex is (h,k) and a is the constant.
Substituting the vertex (4,-3) in the above equation, we get;
---------------(1)
Substituting the point (2,-1) in the above equation, we have;





Thus, the value of a is 
Substituting the value of a in the equation (1), we get;

Thus, the standard form of the equation of the parabola is 
One is reflecting while the other one is staying
Assuming that 10% is the probability of a switch being defective (since left-handedness has nothing to do with the problem):
For a binomial distribution, probability(r out of n) = (nCr) (p)^r (q)^(1-r)
p = 10% = 0.1, q = 1 - p = 0.9
r = 2 switches, n = total of 12 switches
probability = (12C2) (0.1)^2 (0.9)^(12-2)
probability = 66(0.1)^2 (0.9)^10
probability = 0.23
Answer:
=760 ft
Step-by-step explanation:
h=16t^2+126t
Let t=4
h = 16 (4)^2 +126(4)
h = 16*16 +126(4)
=256+504
=760 ft
