Answer:

$(3,6.2)$

Step-by-step explanation:

Residual value the difference between the observed value of the dependent variable and the predicted value is called the residual.

Residual , $R=O-P$ , where R is the residual value, O, is the observed value, and P is the predicted value. The sum and the mean of the residuals are equal to zero.

Now, we can see that the biggest magnitude of the difference is of $-1.1$ and $-1.1$ is at the point $(3,6.2)$ . ( $\left | -1.1 \right |=1.1$ )

Therefore, the point farthest from the line of best fit is the one whose magnitude of residual value is the most and in this case that point is $(3,6.2)$ .

A train leaves boston at 2:00 pm. a second train leaves the same city in the same direction at 6:00 pm. the second train travels

AURORKA [14]

$\boxed {\boxed { \text {Distance = Speed x Time}}}$

First Train:
Time taken = 9 hours (2pm to 11pm)
Let the speed be x
Distance = Time x Speed = 9x

Second Train:
Time taken = 5 hours (6pm to 11pm)
Speed = x + 48
Distance = Time x Speed = 5(x + 48)

Since both the distance they traveled are the same, we equate the distance to solve for x.

Solve for x:
9x = 5(x + 48)
9x = 5x + 240
4x = 240
x = 60

Find the speed:
x = 60 mph
x + 48= 108 mph

Answer: The spend of the two trains are 60 mph and 108 mph.

The difference of 2.5 x $10^{4}$ - 1.5 x 10³ is 2.35 x $10^{4}$ .

<h3>What is the difference?</h3>

Difference is the result of the subtraction of two or more numbers. The numbers are written in scientific notation. Scientific notation is a method that is used to write large numbers.

The exponent of the numbers have different value. In order to evaluate them, they have to have the same values.

2.5 x $10^{4}$ - 1.5 x 10³

2.5 x $10^{4}$ - 0.15 x $10^{4}$

2.35 x $10^{4}$

HELP!!! Plz

Answer:

1.$400.00 2.$4,000.00

Step-by-step explanation:

Scenario: Your team has been hired to provide financial analysis for a start-up company, Bobble in Style, which produces customized bobble heads. The bobble heads are made out of less rigid materials and are more true to life than those of competitors. The company inventors, Mr. and Mrs. Lee, are going to pitch their idea to Shark Tank in a few months, but first they need to have a better understanding of the business financials. The Lee’s are already creating and selling their product from their home-based office and work area. They know what costs are involved with making the bobble heads on a small scale, but they don’t have an understanding of financial figures beyond basic costs. They need you to make sense of various financial figures for them.

Cost Classification: The Lee’s have provided you with the following costs and relevant information that are assumed for year 20XY. Classify the costs as variable costs or fixed costs. Explain the importance of distinguishing between variable and fixed costs. If business is expected to be steady from month to month, provide a monthly budget based on these figures.

Advertising Fees = $4,000

Labor = $400/month

One part-time employee will be hired to take care of packaging and shipping. This employee will be paid $10 per hour. He or she is estimated to work 40 hours total per month.

Packaging Supplies = $3,000

Office Supplies = $800

Phone and Internet Service = $115/month

Product Supplies = $9,000

Shipping Fees = $1,000/month

Conference Exhibitor Fee = $3,000

Travel Expenses for Conference (e.g. airfare, meals, taxi) = $1,200

Utilities for the Home Workshop = $105/month

Break-Even Analysis: You have been asked to calculate how many units need to be sold to break even, based on the costs provided in task #3. Assume that only one conference will be attended and the estimated expenses associated with this conference are on target. Also assume that the value for total units per year is based on sales of 70 units per month. Therefore total units sold per year are 840. The selling price per unit is $79.

Suppose a hurricane traveled 130 miles from point in the Atlantic Ocean to Florida coastline in 6 1/2 hours. How many miles per

Marizza181 [45]

Answer:

The hurricane traveled 260 miles per hour.

Step-by-step explanation:

Given,

Distance covered by hurricane = 130 miles

Then time = $\frac{6}{12}$ hours= $0.5$ hour

Distance=Speed*Time

Speed= $\frac{Distance}{Time}$
Speed= $\frac{130}{0.5}$

Speed=260 miles per hour

So, the hurricane traveled 260 miles per hour
