Answer:

0.585

Step-by-step explanation:

P(A|B) = P(A∩B) / P(B)

P(A|B) = 0.415 / 0.71

P(A|B) = 0.585

Select the correct answer.
Liono4ka [1.6K]

Answer:

Option C.

Step-by-step explanation:

It is given that,

Total number of applicants = 9

Number of job = 3

We need to select 3 applicants out of 9. So, the required number of ways is

^9P_3=\dfrac{9!}{(9-3)!}

^9P_3=\dfrac{9\times 8\times 7\times 6!}{6!}

^9P_3=9\times 8\times 7

^9P_3=504

Therefore, there are ^9P_3=504 ways the positions can be filled because the order in which the applicants are chosen matters.

Hence, the correct option is C.

Finding the volume of a 5.6 by 5.6 cube
ddd [48]

Step-by-step explanation:

The volume of any object needs to be 3d,

so you need to calculate all sides of the cube

it would be base length times base width times the height to get your volume

But since all sides are equal to each other it would be 5.6x5.6x5.6 or 5.6^3=175.616 (units cubed or ^3)

Hope that helps :)

AfilCa [17]

Answer:

y=3x-4

Step-by-step explanation:

Slope intercept form is :

y=mx+b

where m is the slope, and b is the y intercept.

We are given the slope, it is 3. we are also given the y intercept, it is (0,-4). For this form, the 0 in (0,-4) is ignored, and we consider the y intercept to be -4.

So, m is 3, and b is -4. Substitute the values into the equation

y=3x+ -4

y=3x-4

So, the equation in slope intercept form is

y=3x-4
