Answer:

f(x)  = 8  is a constant function.

Step-by-step explanation:

<u>Constant Function</u>: A function is said to be constant if its value is independent of any variable.

here, f(x) = K ;  for some arbitrary constant K for all x.

Here, the given function family is f(x) = 8.

So for all the values of x , the function is independent of x.

Hence, f(x) is a constant function.

Several factors are involved in the creation of a confidence interval. Among them are the sample size, the level of confidence,
Lynna [10]

Answer:

  1. A
  2. A
  3. C
  4. B

Step-by-step explanation:

1) The statement is true. A larger margin of error creates a wider confidence interval, which is more likely to contain the population parameter.

2) The statement is false. A larger sample size decreases the standard error of the sample proportion, which decreases the margin of error.

3)  The statement is true. A smaller sample size increases the standard error of the sample proportion, which, for a fixed margin of error, decreases the critical value, z*.

4)  The statement is true. One can see from the margin of error formula that the margin of error is inversely proportional to the square root of n.

Helppp. Write an equation to solve for a. Then find the missing angle.
kvasek [131]

Answer:

180 = 90 + 52+ a

38 =a

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

180 = 90 + 52+ a

Combine like terms

180 = 142+a

Subtract 142 from each side

180 -142 = 142+ a -142

38 = a

ValentinkaMS [17]

Answer:

The slope is a zero slope. This means that the line is a straight, horizontal line.

Step-by-step explanation:

Use the slope formula.

m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}

5-5/-18-18 = 0/-36
