3-2i+8=23 can you solve this find what i equals

Answers

3 - 2i + 8 = 23

3 + 8 - 2i = 23

11 - 2i = 23

-2i = 12

-2i ÷ -2 = 12 ÷ -2

A 23.9 foot tall streetlight casts a shadow that is 17.7 feet long. How long is the shadow cast by a nearby parking meter that is 3.6 feet high?

Answers

Answer:

2.67 feet long

Step-by-step explanation:

Create a proportion where x is the length of the parking meter's shadow:

[tex]\frac{23.9}{17.7}[/tex] = [tex]\frac{3.6}{x}[/tex]

Cross multiply and solve for x:

23.9x = 63.72

x = 2.67

So, the parking meter's shadow is approximately 2.67 feet long

A manufacturer makes ball bearings that have a target diameter of 5 mm. Quality control engineers sample ball bearings from a batch to test the hypotheses H 0 : mu=5 mm vs. H a : mu ne5 mi , where u is the true mean diameter of the ball bearings in that batch. Suppose that H 0 is actually true. Which situation below would have the lowest probability of a Type I error?

Answers

Answer: n=30 the other one is 0.01 !

Step-by-step explanation:

khan

The situation that would have the lowest probability of a Type I error is the one with the smallest significance level (α).

What is hypothesis testing?

Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.

It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.

We have,

In hypothesis testing,
A Type I error occurs when we reject the null hypothesis (H0) when it is actually true.

The probability of a Type I error is denoted by the symbol alpha (α) and is usually set to a small value, such as 0.05 or 0.01.

Now,

To minimize the probability of a Type I error, we want to choose a significance level (α) that is small.

This means that we are willing to accept a lower probability of detecting a difference when one actually exists (i.e., a higher probability of a Type II error).

For example,

If we set α = 0.01, we are saying that we are willing to accept only a 1% chance of incorrectly rejecting the null hypothesis (H0) when it is actually true. This would result in a very small probability of a Type I error.

Therefore,

The situation that would have the lowest probability of a Type I error is the one with the smallest significance level (α).
