I doubt it's 130. It has to be 75 or 50. I'd go with 75.
The graph of f(x) is stretched vertically by scale factor 3 and translated 2 units to the right to give the graph of 3f(x - 2)²
Step-by-step explanation:
Let us revise the vertical stretch and the horizontal translation
- A vertical stretching is the stretching of the graph away from the x-axis
- If k > 1, the graph of y = k•f(x) is the graph of f(x) vertically stretched by multiplying each of its y-coordinates by k.
- If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)
- If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)
∵ f(x) = x²
∵ f(x) is multiplied by 3
- 3 is greater than 1, then the graph of f(x) is stretched vertically
by scale factor 3
∴ The graph of f(x) is stretched vertically by scale factor 3
∵ x² is changed to (x - 2)²
- That means the graph of f(x) translated 2 units to the right
∴ The graph of f(x) is translated 2 units to the right
The graph of f(x) is stretched vertically by scale factor 3 and translated 2 units to the right to give the graph of 3f(x - 2)²

Answer:
b. It is used to construct confidence intervals for the population mean when the population standard deviation is known
Step-by-step explanation:
Student's t-distribution, also called sometimes just as t distribution, is a probability distribution that is used to estimate population parameters when you have small sample size, specifically when sample size is less than 30, or when the population standard deviation is unknown.
The t distribution allows us to conduct statistical analyses on samples that does not satisfy the conditions for applying <em>standard normal distribution</em>.
Answer:
$110
Step-by-step explanation:
So first you have to do 15*4. We get the 4 from the admission fees and the 15 from the number of dances they attend. From this answer we can see the total of money they will be paying for admission for the 15 dances.
15*4=$60
However, our answer isn't just $50 as we are also told membership costs $50. So no we add $50 to $60, which gives us an answer of $110, which is the amount the member will pay if they attend 15 dances during the school year.
Answer:350
Step-by-step explanation:you multiply the amount of points which is 70 times the amount of targets which is 5 so it’s 70x5=350
