Twenty seven percent of the employees in a company have managerial positions, and 5 percent of the employees in the company have MBA degrees. Also, 59 percent of the managers have MBA degrees. Using the probability formulas, find the proportion of employees who either have MBAs or are managers.
Answer:
Step-by-step explanation:
Given that :
27% employees managerial position
5% Employee have MBA
59% of managers have MBA
Proportion of employees who either have MBA or are managers :
P(either manager or MBA) = P(Manager U MBA)
= P(manager) + P(MBA) - [P(manager n MBA) * P(Manger)]
P(manager ) = 0.27
P(MBA) = 0.05
P(manager n MBA) * P(Manger) = 0.59 * 0.27 = 0.1593
P(manager) + P(MBA) - [P(manager n MBA) * P(Manger)]
= 0.27 + 0.05 - 0.1593
= 0.1607
In ΔDEF, \overline{DF} DF is extended through point F to point G, \text{m}\angle FDE = (2x+4)^{\circ}m∠FDE=(2x+4) ∘ , \text{m}\angle DEF = (3x+3)^{\circ}m∠DEF=(3x+3) ∘ , and \text{m}\angle EFG = (7x-5)^{\circ}m∠EFG=(7x−5) ∘ . Find \text{m}\angle FDE.M∠FDE.
Answer:
18°Step-by-step explanation:
See the diagram attached:
In a triangle, the sum of interior angles is equal to the exterior angle.
According the diagram, the sum of interior angles is given as:
Sum of interior = <FDE+<DEF
Given
<FDE = 2x+4
<DEF = 3x+5
Sum of interior = 2x+4+3x+5
Sum of interior = 5x+9
Exterior angle = <EFG = 7x-5
Equate the interior to the exterior and calculate the value of x:
5x+9 = 7x-5
Collect like terms
5x-7x = -5-9
-2x = -14
x = -14/-2
x = 7
Next is to get <FDE:
<FDE = 2x+4
<FDE = 2(7)+4
<FDE = 14+4
<FDE = 18°
Hence the measure of <FDE is 18°

Some investments in the stock market have earned 10% annually. The total value of the
investment, A. at this rate can be found using A = P(1.10)^n. where P is the initial value of the
investment, and n is the number of years the money is invested. If $1.000 is invested in the
stock market at this annual rate of return, what is the expected total value after 18 years?
$4,054.47
$5,559.92
$18,700.00
$19,800.00
Answer:
$5,559.92.
Step-by-step explanation:
NB: Please note that the $1.000 is not correct. If we use it the none of the option will not be correct which means that the value was a mistake. Obviously, It should have been a ''comma'' instead of a ''full stop''. So, it should be ''...$1,000 is invested...'' and not ''...$1.000 is invested...''
So, without mincing words let us dive right into the solution of this particular problem/question.
We have that the '' total value of the investment, A. at this rate can be found using A = P(1.10)^n. where P is the initial value of the investment, and n is the number of years the money is invested.''
Using the rate given to us, The expected total value after 18 years =A = P(1.10)^n = $1,000 × (1.10)^18 = $5,559.92.
Answer:
$5,559.92

Write an equation for the n th term of the arithmetic seqeuence. Then find a 10
-6, – 9. - 12. - 15, .
Answer:
3n-9
Step-by-step explanation:
Each term increases by 3, so there n should be multiplied by 3.
If the first term (or when n = 1) is -6 and we have 3n, we need to subtract 9 to get -6. This also works for the other terms in the sequence.
The 10th term of the sequence would then be:
3(10)-9

perform the operation (9x^2+7x-6)-(3x^2-8x+7)
Answer:
6x^2 + 15x - 13
Step-by-step explanation:
Combine Like Terms
9x^2 - 3x^2 = 6x^2
7x - (-8x) = 15x
-6 - 7 = 13
Write Equation
6x^2 + 15x - 13
Jamil finds that he reads 1/5 of his 115-page book in 1/4 hour
Answer:
He will read 92 pages in an hour going by the current rate at which he reads
Step-by-step explanation:
The complete question is as follows;
Jamil found that he reads 1/5 of his 115 - page book in 1/4 of an hour. At this rate how many pages does he read in an hour
We proceed as follows;
If he reads 1/5 of 115 in 1/4 hour
1/5 of 115 pages refer to 1/5 * 115 = 23 pages
This means that he reads 23 pages in quarter of an hour
So in an hours the number of pages he will read will be 23 * 4 = 92 pages

2. Solve for x. SHOW YOUR WORK.
Answer:
x=9
Step-by-step explanation:
The two labelled angles are equal, so we can construct an equation. Then, we solve the equation for x.
[tex]4x+2=7x-25\\2=3x-25\\3x=27\\x=9[/tex]
First, we subtract 4x from both sides. Next, we add 25 to both sides. Finally, we divide both sides by 3.
It takes Daphne 25 minutes to assemble a model plane. During her work day Daphne takes 30 minutes for lunch and one 15 minute break. Which inequality could Daphne use to determine the number of model planes
she can assemble in her 8 hour work day?
25p - 458
Answer:
y=25p-45Step-by-step explanation:
We first of all start by cumulating all the time she spent for break
lunch= 30min
break= 15min
total break= 45min
also the time taken to assemble one model plane 25min
let the number of hours be p
and the total number of model plane be y
The model is
y=25p-45
Answer: 25p +45 <480
