Answer:
128 m^2
Step-by-step explanation:
You have 5 sides of a cube on the bottom with length 4
5 * 4x4 = 80 m^2
then four triangles on top
area of triangle = 1/2 base * height base = 4 height = 6
4 * 1/2 ( 4)(6) = 48 m^2
summed = 128 m^2
Answer:
→ The table is:
→ x → -1 → 0 → 1
→ y → -3 → 0 → 3
The graph of the line is figure d
Step-by-step explanation:
∵ y = 3x
∵ x = -1, 0, 1
→ Substitute the values of x in the equation to find the values of y
∴ y = 3(-1) = -3
∴ y = 3(0) = 0
∴ y = 3(1) = 3
→ The table is:
→ x → -1 → 0 → 1
→ y → -3 → 0 → 3
∵ The form of the linear equation is y = m x + b, where
∵ y = 3x
→ Compare the equation with the form
∴ m = 3
∴ b = 0
→ That means the slope is positive, then the direction of the line must
be from left tp right and passes through the origin
∴ The graph of the line is figure d

Answer:
Option B) the minimum acceptable chance of making a type I error.
Step-by-step explanation:
We define significance level as:
- It is denoted by α.
- It is the probability of rejecting the null hypothesis when it is true.
- Thus, it is the type I error.
- Lower significance levels indicate that stronger evidence are required to reject the null hypothesis.
- We compare the significance level to the p-value to decide whether to accept or reject the null hypothesis.
- It is the probability of false positive.
- The probability of making a type I error is α, which is the level of significance.
- For example: A significance level of 0.05 indicates that there is a 5% chance that we are wrong when we reject the null hypothesis because it is actually true. To lower this risk, you must use a lower value for α.
Option B) the minimum acceptable chance of making a type I error.
