Mathematics
1 answer:
Studentka2010 [4]3 years ago
4 0

Answer:

all real numbers greater than or equal to zero

Step-by-step explanation:

The domain of the real function f(x) = sqrt(x) is

all real numbers greater than or equal to zero

because when x < 0, then f(x) will become complex, which does not belong to a real function.

Lee records the height of players on a basketball team, and calculates the mean absolute deviation of the set of data. What does
Luba_88 [7]

The mean absolute deviation can be defined as the average distance between the mean and each of the given data points. It is the absolute value of the deviation.

To find the mean absolute deviation, take the folllowing steps:

1. Find the Mean

2. Find the distance of each value from the mean by Subtracting the mean value from each value

3. Find the mean of the distances

Therefore, the mean absolute standard deviation of the set of data describes the average difference in height between each player and the mean height

ANSWER:

The average difference in height between each player and the mean height

Billy is helping to make pizzas for a school function. He's made 25 pizzas so far. His principal asked him to make at least 30 p
malfutka [58]

Answer:

5 ≤ x ≤ 50; Billy needs to make at least 5 more pizzas but no more than 50

Step-by-step explanation:

Let

x -----> the number of pizzas

we have the compound inequality

30 \leq x+25 \leq 75

Divide the compound inequality into two inequalities

x+25 \leq 75 ----> inequality A

x \leq 75-25

x \leq 50\ pizzas

The solution of the inequality A is the interval -----> (-∞,50]

30 \leq x+25 -----> inequality B

30-25 \leq x

5 \leq x  

Rewrite

x \geq 5

The solution of the inequality B is the interval -----> [5,∞)

therefore

The solution of the compound inequality is

(-∞,50] ∩ [5,∞)=[5,50]

so

5\leq x \leq 50

Billy needs to make at least 5 more pizzas but no more than 50
