Answers

Answer 1

The effect of decreasing the alpha level from 0.05 to 0.01. it decreases the probability that the sample will fall into the critical region, it decreases the probability of a Type I error, and it decreases the size of the critical region.
Therefore, the answer is that all of other options are results of decreasing alpha.

Surface area of a cylinder with a diameter of 14 and height is 9

Answers

The radius is 7 if the diam. is 14. We can find the surface area (without top or bottom areas) by finding the circumference of the base and then multiplying it by the height:

C=pi*d = pi(14); height = 9. Then the surface area of the side(s) is 14(pi)(9).

If you wish to include the areas of the top and bottom of the cylinder, add
2(pi)r^2 = 2(pi)(7)^2.

Dane is 10 times Brian's age. The difference in their age is 27, how old is Brian

Answers

Brian is 3 years old.
Hope this helps!

Answer:

Brain is 3 years old.

Step-by-step explanation:

Let B represent Brain's age and D represent Dane's age.

We have been given that Dane is 10 times Brian's age. We can represent this information in an equation as:

[tex]D=10B...(1)[/tex]

We are also told that the difference in their age is 27. We can represent this information in an equation as:

[tex]D-B=27...(2)[/tex]

Upon substituting equation (1) i equation (2), we will get:

[tex]10B-B=27[/tex]

[tex]9B=27[/tex]

[tex]\frac{9B}{9}=\frac{27}{9}[/tex]

[tex]B=3[/tex]

Therefore, Brain is 3 years old.

What is the equation for the linear model in the scatter plot obtained by choosing the two points to the closest line?
y=-1.5 X +6
yEquals 1.5 X +6

Answers

(4,12) (20,36)
slope = (36 - 12)/(20-4) = 24 / 16 = 3/2 = 1.5

y intercept (0,6) b = 6
equation
y = 1.5x + 6

answer
b. y = 1.5x + 6

Final answer:

The equation for the linear model in a scatter plot can be determined by selecting any two points closer to the line and utilizing them to find its slope and y-intercept. This information is then used to write the equation y = mx + b, where m is the slope and b is the y-intercept.

Explanation:

The question pertains to the equation of the linear model in a scatter plot which basically describes the best fit line passing through the points on the plot. In simple terms, in a scatter plot if you choose any two points closer to the line, we can use these to determine the equation of that line.

Suppose you have two points (x1, y1) and (x2, y2), where x represents the independent variable and y is the dependent variable. To find the slope (m) of the line, we use the formula: m = (y2 - y1) / (x2 - x1). Once the slope is determined, we proceed to find the y-intercept (b), which is the y-value where the line crosses the y-axis.

The general form of a linear equation is y = mx + b. Hence, using the values of slope and y-intecept obtained earlier, we can write the equation of our line. For example, in the equations given in the question, -1.5 and 1.5 are the slopes and 6 is the y-intercept.

Solve the proportion to determine how much Rachel will earn in 10 hours.

Answers

So she earned $34 in 4 hours, meaning she was earning at the rate of 34/4 or $8.5/hour. Is she works for 10 hours at the same rate, it would be 8.5 x 10 = $85. B is the correct proportion.

The correct equation of proportions would be $34 x

First, find the unit rate.
Since the car travels 476 miles with 14 gallons of gas, then 476/14 = 34, so the car can travel 34 miles per gallon.

The distance is 34 times the number of gallons

d = 34g

Now you are given 578 miles, and you need to find the gallons.

578 = 34g

Solve for g by dividing both sides by 34.

A car is tracing at a rate of 72 kilometers per hour. What is the car rates in kilometers per min? How many kilometers will the car travel in 5 mins

Answers

1 hour= 60 minutes

72km/60 minutes= 1.2 km per minute

1.2(5)= 6 km

The car’s unit rate is 1.2 kilometers per minute and the car travel 6 kilometers in 5 minutes.

Hope this helps!

In 5 minutes, the car will travel 6 kilometers.

To convert the car's speed from kilometers per hour to kilometers per minute, we need to divide the given rate by the number of minutes in an hour, which is 60. So, for a car traveling at 72 kilometers per hour, the rate in kilometers per minute is:

72 km/hr / 60 = 1.2 kilometers per minute.

Now, to calculate how many kilometers the car will travel in 5 minutes, we simply multiply the rate in kilometers per minute by the number of minutes:

1.2 km/min * 5 min = 6 kilometers.

Therefore, the car will travel 6 kilometers in 5 minutes at the rate of 72 kilometers per hour.

If a line of one billion people standing shoulder to shoulder stretches 346,439 miles long, what is the average shoulder width, in feet, of the people in the line?

Answers

Final answer:

Given a line of one billion people extending for 346,439 miles, the average shoulder width of a person in the line is approximately 1.83 feet.

Explanation:

To find the average shoulder width of the people in the line, we need to convert the total miles into feet, since the result wanted is in feet. There are 5,280 feet in one mile. So the total length in feet would be 346,439 miles * 5,280 feet/mile = 1,829,029,920 feet. Now, if there are 1 billion people in this line, then the average width of a person's shoulders would be the total length divided by the total number of people. Hence, the average shoulder width = 1,829,029,920 feet / 1,000,000,000 people = approximately 1.83 feet.
