In Exercise sketch the graph of the function.<br> f(x) = ex + 3

Tju [1.3M]

Answer:

$f(x) = e^x + 3$

Step-by-step explanation:

We are given the following function in the question:

$f(x) = e^x + 3$

We have to graph this function.

Properties of given function are:

e is a constant and have a value of e = 2.718281828....
The function does not pass through origin
At x = 0, f(x) = 4
The domain for the given function is all real numbers.
The range of the given function is $(3, \infty)$

The attached image shows the graph for given function.

What is the slope of the line segment with endpoints at (2,-5)<br> and (-1, -1)?

Advocard [28]

Answer:

The slope of the line segment is $m=-\frac{4}{3}$

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have the points

(2,-5) and (-1, -1)

substitute in the formula

$m=\frac{-1+5}{-1-2}$

$m=\frac{4}{-3}$

$m=-\frac{4}{3}$

In order to test whether the average waiting time this year differs from last year, a sample of 25 data were collected this year

netineya [11]

Answer:

(B) 0.74 + or - 2.797 × 0.22/√25

Step-by-step explanation:

Confidence Interval = mean + or - t × sd/√n

mean = 0.74 hours

sd = 0.22 hours

n = 25

degree of freedom = n - 1 = 25 - 1 = 24

Confidence level = 99%

t-value corresponding to 24 degrees of freedom and 99% confidence level is 2.797

Confidence Interval = 0.74 + or - 2.797 × 0.22/√25
