What is the solution set to this inequality, where x is a real number: -4x
Akimi4 [234]

Answer:

x ≥ 9

Step-by-step explanation:

Considering the equation is;

-4x (less than or equal to ) 36 , as provided by the questioner;

-4x ≤ 36

Dividing both sides by -4

-4x/-4≤ 36/-4

We get;

x ≥ -9 , the sign ≤ changes to ≥ since we have divided by a negative.

<h3>x ≥ 9</h3>

Which of the following statements are true regarding functions?
butalik [34]

Answer:

D

Step-by-step explanation:

The vertical line test, can be done with a pencil, and it's very simple. You run the object in a vertical position, horizontally across the graph, and if it hits two points on the same Y-Axis, your function is actually a relation, since functions are not allowed to have two coordinates on the same line.

Listed below are prices in dollars for one night at different hotels in a certain region. Find the​ range, variance, and standar
Vanyuwa [196]

Answer:

Range = $115

Variance = $1915.2857

Standard deviation = $43.764

Step-by-step explanation:

Given the data:

234 160 119 131 218 207 146 141

Arranging in ascending order :

119, 131, 141, 146, 160, 207, 218, 234

The range = maximum - minimum

The range = 234 - 119 = 115

The variance :

Σ(x - mean)²/n-1

The mean = Σx / n

The mean = 1356 / 8 = 169.5

Variance :

Σ(x - mean)² = (119-169.5)² + (131-169.5)² + (141-169.5)² + (146-169.5)² + (160-169.5)² + (207-169.5)² + (218-169.5)² + (234-169.5)² = 13407

n - 1 = 8 - 1 = 7

Variance = 13407 / 7 = 1915.2857

Standard deviation = √variance

Standard deviation = √1915.2857

Standard deviation = $43.764
