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

choli [55]

Answer:

The value of f(-3) = -3

Step-by-step explanation:

It is given that f(x) = 3(x+2), in order to find f(-3), we have to substitute x = -3 into the function, f(x) :

f(x) = 3(x+2)

f(-3) = 3(-3+2)

= 3(-1)

= -3

Tia and her five friends are going to the ice skating rink. Each person $5 for admission and $5 for food. Write and evaluate a n
ozzi

Where C = Cost and P = People


C = 2(5p)


In the context of Tia and her five friends:


C = 2(5*6) = 2(30) = 60

C = 60


The cost for Tia and her five friends to be admitted to ice skate and eat is 60$, and the equation to calculate this is C = 2(5p).
