George Smith own's George's Joint, a gas station and convenience store. George is trying to get a better understanding of his business and wants to estimate the mean number of gallons of gasoline sold to his customers. Assume the number of gallons of gasoline sold follows a normal distribution with a population standard deviation of 2.3 gallons. From his records, he randomly selects 60 sales and find the mean number of gallons sold is 8.6. What is the point estimate of the population mean

Answers

Answer:

The point estimate of the population mean is of 8.6 gallons sold.

Step-by-step explanation:

Point estimate for the population mean:

From a large sample, the point estimate for the population mean is the sample mean.

In this question:

The sample mean number of gallons sold is 8.6. This means that the point estimate of the population mean is of 8.6 gallons sold.

Explain how to solve 5x^2-3x=25 by completing the square. What are the solutions?

Answers

Answer:

x1 = √(509) /100 + 3/10

x2 = -√(509) /100 + 3/10

Step-by-step explanation:

We do completing the square as follows:

1. Put all terms with variable on one side and the constants on the other side.

5x^2 - 3x = 25

2. Factor out the coefficient of the x^2 term.

5(x^2 - 3x/5) = 25

3. Inside the parentheses, we add a number that would complete the square and also add this to the other side of the equation. In this case we add 9/100 and on the other side we add 9/20.

5(x^2 - 3x/5 + 9/100) = 25 + 9/20

4. We simplify as follows:

5(x^2 - 3x/5 + 9/100) = 25 + 9/20

5(x - 3/10)^2 = 509/20

(x - 3/10)^2 = 509/100

x1 = √(509) /100 + 3/10

x2 = -√(509) /100 + 3/10

The missing value is 24.

We have,

From the figure,

We can write an expression as:

4:5 = x : 30

This can be written as,

4/5 = x/30

Now,

Cross multiply.

x = 4 x 30 / 5

x = 4 x 6

x = 24

Thus,

The missing value is 24.

Simplify the following expression:

A. 21+7
B. -27 +10;
C. 14 +6;
D. 8 +41

Answers

The complex expression (i-3) +6i-3(8 - i) when simplified is -27 + 10i

How to simplify the complex expression

From the question, we have the following parameters that can be used in our computation:

(i-3) +6i-3(8 - i)

Express properly

So, we have

(i - 3) + 6i - 3(8 - i)

When the brackets are opened, we have

(i - 3) + 6i - 3(8 - i) = i - 3 + 6i - 24 + 3i

Collect the like terms

So, we have

(i - 3) + 6i - 3(8 - i) = - 3 - 24 + i + 6i + 3i

Evaluate the like terms

So, we have

(i - 3) + 6i - 3(8 - i) = -27 + 10i

Hence, the complex expression when simplified is -27 + 10i
