Which function is graphed on the right?

Norma-Jean [14]

Answer: $y=2^{x-2}+3$

Step-by-step explanation:

To find the equation from a graphed function, you can substitute points into each equation to find the original:

A point on the graph is (2, 4). Substituting this into each equation, we get:

$4=2^{2+3} -2$ , which claims that 4 is equal to 30, which is incorrect.

$4=2^{2-3} +2$ , which claims that 4 is equal to 3/2, which is incorrect.

$4=2^{2-2}+3$ , which claims that 4 is equal to 4, which is correct.

We can test the third function further by taking another point on the graph, (3, 5), and substituting it into the function:

$5=2^{3-2} +3$ , which claims that 5 is equal to 5, which is correct.

An agency is studying the income of store managers in the retail industry. A random sample of 25 managers reveals a sample mean

aalyn [17]

Answer:

The Confidence Interval = ($44,745.55 , $46,094.45)

Step-by-step explanation:

The formula for Confidence Interval =

Confidence Interval = Mean ± z × Standard deviation/√n

Where n = number of samples = 25 managers

Standard deviation = $2,050

Mean = $45,420

z = z score of the given confidence interval

= z score of 90% confidence interval

= 1.645

Confidence Interval = $45,420 ± 1.645 × $2,050/√25

= $45,420 ± 1.645 × $2,050/5

= $45,420 ± 674.45

Confidence Interval =

$45,420 - 674.45 = $44,745.55

$45,420 + 674.45 = $46,094.45

Therefore, the Confidence Interval = ($44,745.55 , $46,094.45)

Ben is decorating his home with vases of flowers. He bought glass vases that cost $22 each and ceramic vases that cost $14 each.

Evgen [1.6K]

Answer:

Step-by-step explanation:

x + y = 10

22x + 14y = 172

-22x - 22y = -220

22x + 14y = 172

-8y = - 48

y = 6 ceramic vases

x + 6 = 10

x = 4 glass vases
