ololo11 [35]
Conditional probability formula is:P ( A and B ) = P ( A ) · P ( B / A )0.46 = P ( A ) · 0.31P ( A ) = 0.46 : 0.31P ( A ) = 1.48And this is impossible because 0 ≤ P ( A ) ≤ 1The student obviously made a mistake.

max and some friends shared the cost of a meal. The meal cost $51 and each person contributes $17. How many people share the cos
stiv31 [10]

Answer:

3 people

Step-by-step explanation:

$51/$17 = 3 people

- We know to start with $51 dollars because that is the total price of the meal.

- We also know each meal costs $17.

- Next, ask youself what we are trying to find? We are trying to find how many people are eating.

- Therefore to find that we need to take our starting amount $51 divided by $17 because that is the cost of 1 meal.

- $51/$17 = 3 people (whole cost/individual cost = # of people)

- To check this take 3 x 17 = 51 (Now we know it is correct)

- If you would like a further explanation please let me know.

If ƒ(x ) = 3x + 1 and and ƒ -1 = , then the ordered pair of ƒ -1(10) = (10, 31) (10, 3) (3, 10)
MAXImum [283]
        f(x) = 3x + 1
           y = 3x + 1
      y - 1 = 3x + 1 - 1
      <u>y - 1</u> = <u>3x</u>
         3       3
¹/₃y - ¹/₃ = x
           y = ¹/₃x - ¹/₃
      f⁻¹(x) = ¹/₃x - ¹/₃
    f⁻¹(10) = ¹/₃(10) - ¹/₃
    f⁻¹(10) = 3¹/₃ - ¹/₃
    f⁻¹(10) = 3
It is equal too (10, 3).

In a college archaeology class, 78 students are going to a dig site to find and study artifacts. The dig site has been divided i
const2013 [10]

Answer: There are 9 sections of group of 2 and 15 sections of group of 4.

Step-by-step explanation:

Since we have given that

Let the number of sections of group of 2 students be 'x'.

Let the number of sections of group of 4 students be 'y'.

So,total number of sections = 24

According to question, it becomes,

x+y=24----------------(1)

Number of students going to dig = 78

So, it becomes,

2x+4y=78\\\\x+2y=39---------------(2)

From, eq(1), we get that

x=24-y

Put in EQ(2), we get that

x+2y=39\\\\24-y+2y=39\\\\y=39-24\\\\y=15

So, the value of x is 24-15=9

Hence, there are 9 sections of group of 2 and 15 sections of group of 4.
