Total number of employee working for four hours per shift for the manager is 2 people.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event. The probability of an event can not be more than the number 1.

The probability of failure of an event is equal to the difference of the 1 to the success of the event.

Here, the manager records the number of hours, X, each employee works on his or her shift and develops the probability distribution below.

Probability Distribution

Hours Worked: X     Probability: P(X)

           3                         0.1

           4                           ?

           5                        0.14

           6                         0.3

           7                        0.36

           8                       0.06

As, the probability of an event can not be more than the number 1. Thus, the sum of all the probabilities will be equal to 1.

Let suppose the probability of people working for four hour is x. Therefore,

[tex]0.1+x+0.14+0.3+0.36+0.06=1\\x+0.96=1\\x=1-0.96\\x=0.04[/tex]

Now, the total number of people work for the manager is 50. Therefore, total number of people working for 4 hours are,

[tex]0.04\times50=2[/tex]

Hence, total number of employee working for four hours per shift for the manager is 2 people.

Answer:

-12 and 2; it is factored as [tex](x+2)(x-12)[/tex]

Step-by-step explanation:

Since their product is negative, one is positive and the other is negative.

Moreover, since the sum is negative the greater of the two is negative.

Considering that factors of 24 are 1, 2,4,6, 12, 24 you have the following options:

-24 and 1. Sum gets to -23. Nope.

-12 and 2. Sum is indeed -10. Check!

-6 and 4. Sum is -2. Nope again.

The two numbers are thus -12 and 2. The factorization becomes

[tex]x^2-10x-24 = (x+2)(x-12)[/tex]

Answer:

Step-by-step explanation:

132 + (4x - 10) + (5x - 11) + 128 + (4x+2) = 540 All convex 5 sided figures have  540 degrees.        Remove the brackets.

132+ 4x - 10 + 5x - 11 + 128 +4x + 2 = 540      Collect like terms

13x + 241 = 540                                               Subtract 241 from both sides.

13x = 540 - 241

13x = 299                                                         Divide by 13

x = 299/13

x = 23

<P = 4x + 2

<P = 92 + 2

<P = 94

Answer:

Maria 69       Rizal    23

Step-by-step explanation:

M =Maria

(1/3)M = Rizal

                  M-46= (1/3)M

Multiply  both sides by 3 to eliminate fraction

3M-138 =M

138=2M

69= M   (Maria =69)

 69/3= 23

69-46=23

Answer:

$12,000

Step-by-step explanation:

Use the simple interest formula: P = A(1 + rt)

P = final balance (?)

A = starting balance (10,000)

r = interest rate (0.05)

t = years (4)

P = 10,000(1 + 0.05 · 4)

P = 10,000(1 + 0.2)

P = 10,000(1.2)

P = 12,000
