<span>We say a function is undefined when the value gotten isn't present in the domain of the function, like division by a 0 denominator or 0 to the power of 0. That said, we would like to find out whether at each point in the domain, the two points x = 3 and x = 4 exist i.e we don't end up with the indeterminate form. Okay at x =3, we have f(3) = (3-6) (3+3) (3+4)/(3+6) (3-3) (3-4) = (-3) (6) (7) / 0 which is undefined. We don't have to show for x =4 since "4" is negative in the denominator. We would also end up with an undefined function. So, yes, Angie is right.</span>
Answer:
okay i need to know the options
Step-by-step explanation:
Answer:
a)
b) 1.64
c) (16.57,19.85)
d) The sample size must be 135 or greater if the error must not exceed $1.00.
Step-by-step explanation:
We are given the following information in the question:
Sample size, n = 50
Sample mean = $18.21
population standard deviation = $5.92
a) Point estimate for the population mean cost
b) Margin of error =
Margin of error =
c) 95% Confidence interval
Putting the values, we get,
d) Marginal error less than $1.00
Thus, the sample size must be 135 or greater if the error must not exceed $1.00.
Answer: 8
Step-by-step explanation: 2x4=8
Your doing 4 x 4 or 2 x2 x 2 x2
Answer:
0.833 miles
Step-by-step explanation:
Because you know the area, you can use the formula for area of a rectangle. Just plug in what you know and solve.
30/54 is the same as 5/9.
Multiply by its denominator.
Simplify
Divide by 30
5/6 is roughly 0.833
