Answer: If the circumference of a circle is 6.28 inches, the diameter is 6.28 inches / 3.14, which equals 2.

Step-by-step explanation:

So, C=πd

d = C/π

d = 6.28/3.14

<h2> <em>d = 2 inches ← ANSWER :)</em></h2>

Hello from MrBillDoesMath!

Answer: x = 4, slope intercept form is y = 2x + 11

Discussion:

A vertical line goes straight up and down. The only thing "fixed" about it is its x value. Hence a vertical line has an equation like "x = ?". As your line passes through (4, -3), with x value 4. its equation is x = 4.

The slope intercept form of a line is " y = mx + b" where m is the slope of the line and b is its y intercept. We are told the desired line is parallel to y = 2x -1 which means both lines have the same slope (which is 2, boldfaced, above). So, we know the slope intercept form is

y = 2x + b

but we are also told the line passes through (-3,5). Substituting these values in the above equation gives

y = 2x + b

5 = 2 (-3) + b

5 = -6 + b

b = 5 + 6 = 11

The final slope intercept form is y = 2x + 11

Assume that a hypothesis test to support the given claim will be conducted. Identify the type l error for the test. A skeptical

Mars2501 [29]

Answer:

Option D) Reject the claim that the proportion of Americans that have seen a UFO is equal to 5 in a thousand when that proportion is actually 5 in a thousand.

Step-by-step explanation:

We are given the following information:

A hypothesis test to support the given claim that the proportion of Americans that have seen a UFO is less than 5 in a thousand.

Type I error:

Type I error is the rejection of a true null hypothesis that is we reject the null hypothesis given it is true.
It is also known as a false positive.

First, we design the null and the alternate hypothesis

$H_{0}: \text{ The proportion of Americans that have seen a UFO is equal to 5 in a thousand}\\H_A: \text{ The proportion of Americans that have seen a UFO is less than 5 in a thousand}$

Thus, for the given hypothesis test, we describe type I error as:

Option D) Reject the claim that the proportion of Americans that have seen a UFO is equal to 5 in a thousand when that proportion is actually 5 in a thousand.
