A simple random sample of 100 concert tickets was drawn from a normal population. The mean and standard deviation of the sample

were $120 and $25, respectively. Test the hypothesis H0: µ = 125 vs. H1: µ ≠ 125 at the 1% significance level. Rejection region: | t | > t0.05,99 = 1.66 Test statistic: t = -2.0 p-value one tail= 0.024 p-value two tail= 0.048

If the point (4,-1) is a point on the graph of f then f
PIT_PIT [12445]

If the point (4,-1) is part of the graph of y = f(x), then the related point on the graph of y = g(x) would be: (4,-1/2), (2,-1), (-1,-1), (1,4), (4,-4), (-12,1)

  1. g(x) = \frac{1}{2} f(x) => (4,-1/2)
  2. g(x) = f(x-2) => (2,-1)
  3. g(x) = f(-x) => (-1,-1)
  4. g(x) = f(4x) => (1,4)
  5. g(x) = 4f(x) => (4,-4)
  6. g(x) = -f(x) => (-12,1)

Further explanation

  1. Dividing the function by 2 results in all the y-values being halved as well. Thus, to determine the new point, we take the y-value (-1) and halve it to arrive at -1/2. Hence, the new point is (4,-1/2).
  2. When 2 is subtracted from the function's input, it shifts all x-values up by 2. Therefore, to adjust the x-value (4), we add 2 to get 2. Thus, the new point is (2,-1).
  3. Making the function's input negative alters each x-value by multiplying by -1. Consequently, to find the new point, we take x-value (4) and apply -1 to get -1. Therefore, the new point is (-1,-1).
  4. Multiplying the function's input by 4 results in each x-value being divided by 4. To find the new x-value from 4, we divide by 4 to get 1. Hence, the new point becomes (1,4).
  5. When multiplying the entire function by 4, each y-value is increased fourfold. Thus, the original value of 4 becomes -4, making the new point (4,-4).
  6. By multiplying the entire function by -1, each y-value is also multiplied by -1. As a result, the new y-value becomes 1, leading to the new point (-12,1).

If the ratio of the sides of two squares is 3:1, what is the ratio of their perimeters?
Inessa [12570]

Answer:

The ratio of the perimeters is 3:1

Step-by-step explanation:

Given: The ratio of the sides of two squares is 3:1

To find: The ratio of their perimeters

Solution: Let the lengths of the sides be represented as 3:1 = 3x: x

  Perimeter of a square = 4(side)

Using this formula,

Perimeter of square 1 = 4 × 3x = 12x

Perimeter of square 2 = 4 × x = 4x

The ratio of the perimeters of square 1 and square 2 is = 12x: 4x

= 3: 1
