Number of returns = 47
Number of returns that contain errors = 5
Number of returns that does not contain error = 47 - 5 = 42

P(selecting none that contains error in the unreplaced selection) = 42/47 x 41/46 x 40/45 = 68880 / 97290 = 0.708

option C is the correct answer.

In which direction does the right side of this graph point? F(x)= -x^4-x^3+4x-2
suter [353]

Answer: Down

Step-by-step explanation:

We know that the graph of  y = x 4  has both arms pointing up.

Now, since the leading coefficient of  f ( x )  is negative, both arms are pointing down. Thus the right side is pointing down.

A recipe uses 5 cups of milk to make 10 servings. If the same amount of milk is used for each serving, how many servings can be
Margaret [11]

Answer: 24 servings

Step-by-step explanation:

First and foremost, we should note that:

4 cups = 1 quart

Therefore, 3 quarts = 3 × 4 cups = 12 cups

Since she uses 5 cups of milk to make 10 servings, it means that 1 cup of milk is used to make 2 servings. Therefore, 12 cups would be used to make:

= 12 × 2

= 24 servings.

Select the correct answer.
ratelena [41]

Answer:

A.x(x+12) -7(x+12)

Step-by-step explanation:

Factoring is the process of taking common terms out of an expression such that one can represent the expression as the result of smaller values. When given the following expression:

x^2 +5x - 84

First, represent the linear term as the sum of two terms such that each term shares a common factor with the other terms in the expression.

x^2 +12x - 7x - 84

Now take out the common factors,

x(x+12) -7(x+12)

Thus, the correct option is choice (A).

Tamara finds the sum of two number cubes rolled at the same time. The chart below shows all possible sums from the 36 possible c
Georgia [21]

Answer:

18 times

Step-by-step explanation:

Sample space ; roll of 2 number cubes = 6^2 = 36

Sum of 4 in 2 cube rolls = 3

Probability = required outcome / Total possible outcomes

P(sum of 4) = 3 / 36 = 1 / 12

If number cube is rolled 216 times :

Probability on 1 roll * Number of rolls

(1 / 12) * 216

0.0833333 * 216

= 18
