A job fair was held at the Student Union. 25% of the students who attended received job offers. Of all of the students at the jo

vovangra [49]

Answer:

A) Both events are not independent.

B) Both events are not mutually exclusive

C) 8.33%

D) 80%

Step-by-step explanation:

A) Both events are not independent. This is because, If B occurs it means that it is very likely that J will occur as well.

B) Both events are not mutually exclusive. This is because it is possible for both events J and B to occur at the same time.

C) we want to find the probability that Joe who is not a business student will receive the job offer.

This is;

P(J|Not B) = P(J & Not B)/P(Not B)

Now,

P(J & Not B) = P(J) – (P(B) × P(J | B))

25% of the students who attended received job offers. Thus; P(J) = 0.25

40% were from the College of Business. Thus;

P(B) = 0.4

Among the business students, 50% received job offers. Thus;

P(J|B) = 0.5

Thus;

P(J & Not B) = 0.25 - (0.4 × 0.5)

P(J & Not B) = 0.25 - 0.2

P(J & Not B) = 0.05

Since P(B) = 0.4

Then, P(Not B) = 1 - 0.4 = 0.6

Thus;

P(J|Not B) = 0.05/0.6

P(J|Not B) = 0.0833 = 8.33%

D) This probability is represented by;

P(B | J) = P(B & J)/P(J)

P(B & J) = (P(B) × P(J | B)) = (0.4 × 0.5) = 0.2

P(B | J) = 0.2/0.25

P(B | J) = 0.8 = 80%

Find the difference between the product of 26.22 and 3.09 and the sum of 3.507, 2.08,

Inessa05 [86]

The product of 26.22 and 3.09 is:
26.22 * 3.09 = 81.0198

The sum of 3.507, 2.08, 11.5, and 16.712 is:
3.507+ 2.08 +11.5+ 16.712 = 33.799

The difference between the product and the sum is:
81.0198 - 33.799 = 47.2208

Which terms could be used as the first term of the expression below to create a polynomial with a degree of 5 written in standar

Sladkaya [172]

Answer:

Option 2 - $-4x^3y^2$

Option 5 - $5x^4y$

Step-by-step explanation:

To find : Which terms could be used as the first term of the expression below to create a polynomial with a degree of 5 written in standard form?

Solution :

The polynomial with a degree of 5 means the polynomial of highest power must be 5.

Now, we check one by one,

1) $2x^2y^2-3xy^3$ - the highest degree is 4

2) $-4x^3y^2$ - the highest degree is 5

3) $x^3$ - the highest degree is 3

4) $8.4x^4y^2$ - the highest degree is 6

5) $5x^4y$ - the highest degree is 5

6) $-xy^3$ - the highest degree is 4

Therefore, In the above options- option 2 and 5 has the highest degree 5 which means they both have a polynomial with a degree of 5.

Answer:

$\large \boxed{\mathrm{served \ a \ greater \ variety \ of \ ages}} \\ \\ \large \boxed{\mathrm{range}}$

Step-by-step explanation:

Restaurant A served a greater variety of ages than Restaurant B, because the range of data for Restaurant A is greater than that of Restaurant B.

Range of a data set is the data spread.

Restaurant A is serving a greater variety of ages of people since it has a higher range than that of Restaurant B.
