Hello,

$5 400 000 - $4 500 000 = $900 000
( 900 000 / 4 500 000 ) × 100 = 20 %

Bye :)

A small business employee 98 people. All of the employees work for 8 hours a day 5 days a week .eleven of the employees receive
Murljashka [212]

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

Find the equation, (f(x) = a(x - h)2 + k), for a parabola containing point (2, -1) and having (4, -3) as a vertex. What is the s
postnew [5]

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 y=a(x-h)^2+k where the vertex is (h,k) and a is the constant.

Substituting the vertex (4,-3) in the above equation, we get;

y=a(x-4)^2-3  ---------------(1)

Substituting the point (2,-1) in the above equation, we have;

-1=a(2-4)^2-3

-1=a(-2)^2-3

-1=4a-3

  2=4a

  \frac{1}{2}=a

Thus, the value of a is \frac{1}{2}

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

y=\frac{1}{2}(x-4)^2-3

Thus, the standard form of the equation of the parabola is y=\frac{1}{2}(x-4)^2-3

10% of a group is left handed. If a random sample of 12 switches is selected, what is the probability of exactly two of the swit
Paraphin [41]
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

If an object is projected upward with an initial velocity of 126ft per? sec, its height h after t seconds is h=?16t^2+126t. Find
Archy [21]

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
