f(x-3) = (x-3)^2 - 8
f(x-3) = (x-3)(x-3) - 8
f(x-3) = x^2 - 6x + 9 - 8
f(x-3) = x^2 - 6x + 1
Carmel is watching a play at the theatre.
The play started at 16 30
The play is 115 minutes long.
When the play ends, Carmel takes 30 minutes to get to the bus stop.
A bus leaves the bus stop at 18 45
Does Carmel get to the bus stop in time to get this bus?
You must show all your working.
Need help
Step-by-step explanation:
play started 16:30
its 115 min long = 1:55 hours
16:30+ 1:55=18:25 hours
now he takes 30 min to reach bus stop
18:25 + 30 mins = 18:55
therefore, he reaches the bus stop 10 mins late

What number is rational, less than 0, greater than -4 but is not an integer?
1. True or false:
The ordered pair (3, 4) is a solution for the equation:
5x + 2y = 23
2. True or false:
The ordered pair (0, 4) is a solution for the equation:
5x + 2y = 23
1) true
2)false
Step-by-step explanation:
1) 5(3)+2(4) = 23
= 15+8=23
23=23
thus, (3,4) is solution for 5x + 2y = 23
2) 5(0)+2(4) =23
= 0+8 is not 23
thus, (0,4) is not solution for 5x + 2y = 23

wild touring the city Bernie buys lunch for his family from a food truck he purchase more Taco for 2.75 and four cheeseburgers if he spent a total of 23.75 how much was each cheeseburger
Answer:
Each cheeseburger was $5.25.
Step-by-step explanation:
He purchased:
A taco for $2.75.
Four cheeseburgers, each for x.
In total, he spent $23.75.
How much was each cheeseburger?
This is the value of x. We have that:
[tex]2.75 + 4x = 23.75[/tex]
[tex]4x = 21[/tex]
[tex]x = \frac{21}{4}[/tex]
[tex]x = 5.25[/tex]
Each cheeseburger was $5.25.

Find the inverse of f(x) = 6x.
The inverse is
g(x) =
Graph the function and its inverse
Given:
The function is:
[tex]f(x)=6x[/tex]
To find:
The inverse of the given function, then draw the graphs of function and its inverse.
Solution:
We have,
[tex]f(x)=6x[/tex]
Step 1: Substitute [tex]f(x)=y[/tex].
[tex]y=6x[/tex]
Step 2: Interchange x and y.
[tex]x=6y[/tex]
Step 3: Isolate variable y.
[tex]\dfrac{x}{6}=y[/tex]
Step 4: Substitute [tex]y=f^{-1}(x)[/tex].
[tex]\dfrac{x}{6}=f^{-1}(x)[/tex]
Therefore, the inverse of the given function is [tex]f^{-1}(x)=\dfrac{x}{6}[/tex] and the graphs of these functions are shown below.
Note: The inverse function is [tex]g(x)=f^{-1}(x)[/tex].

Step-by-step explanation:
A researcher surveyed 220 residents of a city about the number of hours they
spend watching news on television each day. The mean of the sample was
1.8 with a standard deviation of 0.35.
The researcher can be 95% confident that the mean number of hours all the
residents of the city are watching news on television is 1.8 with what margin
of error?
Margin of error is 4.645% with 95% confidence that the mean number of hours all the residents of the city are watching news on television is 1.8 .
Data given :
A researcher surveyed 220 residents of a city about the number of hours they spend watching news on television each day. The mean of the sample was 1.8 with a standard deviation of 0.35 .
The researcher can be 95% confident that the mean number of hours all the residents of the city are watching news on television is 1.8 with what margin of error,
By formula of margin of error = [tex]M = 1.96 \times S / \sqrt{N} ,[/tex]
[tex]Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}}[/tex]
z - represents the z-value for the required confidence level .
s - represents the standard deviation of the sample .
N - represents the sample size .
Now, using the above information, compute the margin of error as -
[tex]\therefore \ Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}} \\= 1.96 \times \frac{0.35}{\sqrt{220}}[/tex]
[tex]=0.04625 (rounded \ to \ 5\ decimal\ places) \\\\ =4.625\%[/tex]
Thus, the margin of error, M, is approximately 4.625% .

A reproductive clinic had a success rate of 25% of patients with live births in 2008. They want to update their success rate (the proportion of live births) for 2020. If they want their estimate to be within 2.5%, how many patient's results should they sample if they plan to use a 99% confidence interval? Round your answer up to the nearest integer.
Answer:
They should sample the results of 1990 patient results.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
A reproductive clinic had a success rate of 25% of patients with live births in 2008.
This means that [tex]\pi = 0.25[/tex]
99% confidence level
So [tex]\alpha = 0.01[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].
If they want their estimate to be within 2.5%, how many patient's results should they sample if they plan to use a 99% confidence interval?
They should sample n patients.
n is found for [tex]M = 0.025[/tex]. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.025 = 2.575\sqrt{\frac{0.25*0.75}{n}}[/tex]
[tex]0.025\sqrt{n} = 2.575\sqrt{0.25*0.75}[/tex]
[tex]\sqrt{n} = \frac{2.575\sqrt{0.25*0.75}}{0.025}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.575\sqrt{0.25*0.75}}{0.025})^2[/tex]
[tex]n = 1989.2[/tex]
Rounding up:
They should sample the results of 1990 patient results.
