According to a recent report, 60% of U.S. college graduates cannot find a full time job in their chosen profession. Assume 57% of the college graduates who cannot find a job are female and that 18% of the college graduates who can find a job are female. Given a male college graduate, find the probability he can find a full time job in his chosen profession? (See exercise 58 on page 220 of your textbook for a similar problem.)

Answers

Answer:

There is a 55.97% that a male can find a full time job in his chosen profession.

Step-by-step explanation:

We have these following probabilities:

A 60% probability that a college graduates cannot find a full time job in their chosen profession.

A 40% probability that a college graduates can find a full time job in their chosen profession.

57% of the college graduates who cannot find a job are female

43% of the college graduates who cannot find a job are male

18% of the college graduates who can find a job are female

82% of the college who can find a job are male.

Given a male college graduate, find the probability he can find a full time job in his chosen profession?

The total males are 43% of 60%(Those who cannot find a job) and 82% of 40%(Those who can find a job). So the percentage of males is $P(M) = 0.43*0.60 + 0.82*0.40 = 0.586$

Those who are males and find a job in their chosen profession are 82% of 40%. So $P(M \cap J) = 0.82*0.40 = 0.328$

$P = (P(M \cap J))/(P(M)) = (0.328)/(0.586) = 0.5597$

There is a 55.97% that a male can find a full time job in his chosen profession.

Thr sum of 2 numbers is 97.The greater number is three less then four times the lesser number.Find the numbersneed answer soon PLEASE!!!!

Answers

Answer:

Greater number: 77 Lesser number: 20

Step-by-step explanation:

Sooo

20 × 4 is 80

80 - 3 = 77

77 + 20 = 97

Answer:

77 & 20

Step-by-step explanation:

x+y=97

x=4y-3

4y-3+y=97

5y=97+3

5y=100

5 5

y=20

x=4y-3

x=4(20)-3

x=80-3

x=77

Answers

Answer:

Step-by-step explanation:

Since the 3 numbers have a ratio of 2:3:7, that means it simplifies to that. So, there must be a common factor, let’s say x, for each of the numbers. Thus, the numbers are 2x, 3x, and 7x. To find the mean, we add up all of the numbers and divide by the number of numbers: (2x + 3x + 7x)/3 = 12x/3 = 4x = 48. Dividing by 4 on both sides gets x = 12. The median of the numbers is the number in the middle which is 3x. Substituting x = 12, we get: 3(12) = 36.

A spherical tank has a radius of 6 yards. It is filled with a liquid that costs $7.50 percubic yard. What is the total value of the liquid in the tank? Use 3.14 for
$1695.60
$6782.40
$904.32
$565.20

Answers

The solution is Option B.

The total cost of the liquid in the spherical tank is $ 6782.40

What is a Sphere?

A sphere has a spherical, symmetrical shape. It is a three-dimensional solid with equal distances between each surface point and the center. On the basis of its radius, it has a surface area and a volume. There are no faces, corners, or edges on it.

The volume of a sphere is given by the formula

Volume of Sphere = ( 4/3 )πr³

where r is the radius of the sphere

Given data ,

Let the total cost of the liquid in the spherical tank be = A

Let the radius of the spherical tank be = R

The value of R = 6 yards

Now the cost of the liquid in the tank per cubic yard = $ 7.50

And ,

The volume of spherical tank = ( 4/3 )πR³

Substituting the values in the equation , we get

The volume of spherical tank = ( 4/3 ) x 3.14 x ( 6 )³
