The mean of a dataset is the average of the dataset.
The mean of the sample in the third row is 2.2
The dataset is given as:
5 5 3 0 6 2 2 4 5 2 3 4 3 0 1 4 0 4 3 6
From the complete question, the samples in the third row are:
Sample: 3 4 3 0 1
The mean of a dataset is calculated using:
[tex]\bar x = \frac{\sum x}{n}[/tex]
Where:
n = 5 i.e. the number of samples
So, we have:
[tex]\bar x = \frac{3 + 4 + 3 + 0 + 1}{5}[/tex]

The Escobar family went on a car trip. They drove 100 miles on country roads and 240 miles on the highway. They drove 50% faster on the highway than on the country roads. Let r represent their rate on country roads in miles per hour. a. Write and simplify an expression that represents the number of hours it took the Escobar family to complete their trip in terms of r. (Hint: 50% faster means 150% of the original rate.) b. Find their total travel time if they drove the posted speed limit.
Answer: Hey I'm sorry I didn't get to answer your question it's just that I need the points because I don't have enough to get help with my question. I hope you get the answer that you need for you question. Good Luck :)..
Explanation:
The expression that represents the number of hours it took the Escobar family to complete their trip in terms of r is 260/r
The expression for the total time of travel?Let r represent their rate on country road and R represent their rate on highway.
So, we have:
R = (100% + 50%) * r
Evaluate
R = 1.5r
Rate is calculated using:
Rate = Distance/Time
So, we have:
r = 100/t and R = 240/T
Make T and t the subject
t = 100/r and T = 240/R
The total time of travel is:
Total = t + T
So, we have:
Total = 100/r + 240/R
Substitute R = 1.5r
Total = 100/r + 240/1.5r
Simplify
Total = 100/r + 160/r
Evaluate the sum
Total = 260/r
The total time of travelThe speed limit is 40mph
This means that:
r = 40
In (a), we have:
Total = 260/r
Substitute 40 for r
Total = 260/40
Evaluate
Total = 6.5
Hence, their total time of travel is 6.5hours

Managers at eller manufacturing are considering purchasing a new refrigerated delivery truck that will produce equal annual cash flows of $36,000 for 6 years. The truck’s net present value is $12,780, its cost is $144,000, its useful life is 6 years, and its annual depreciation expense (no salvage value) is $24,000. What is the discount rate used by eller to evaluate this project?.
It should be noted that the discount rate that was used by Eller to evaluate this project is 10%.
From the information given, the following can be depicted:
Annual cash inflows = $36,000 Period of cash inflows = 6 years Cash outlay (initial investment) = $144,000 Depreciation expense = $24,000 Estimated useful of trucks = 6 years Net present value = $12,780It should be noted that the Present Value Annuity Factor at 10% for 6 years is given as 4.355
Therefore, the Present Value of Annuity cash inflows will be
= ($36,000 x 4.355) = $156,780
Less initial investment cash outlay = $144,000
Net present value = $12,780

How do you grow rice
Answer:
put some rice in a pot
Then mix it up with some sauce
pour in some dirt
and you'll get some sweet plant
Explanation:
Ideally, you need at least 40 continuous days of warm temps over 70 F. (21 C.) to grow rice.
First, you need to find one or several plastic containers without holes. One or several depends upon how many miniature pseudo rice paddies you want to create. Next, either purchase rice seed from a gardening supplier or buy long grain brown rice from a bulk foods store or in a bag. Organically grown rice is best and it can’t be white rice, which has been processed.
Fill the bucket or plastic container with 6 inches (15 cm.) of dirt or potting soil. Add water up to 2 inches (5 cm.) over the soil level. Add a handful of the long grain rice to the bucket. The rice will sink to the dirt. Keep the bucket in a warm, sunny area and move it to a warm place at night.
Rice plants don’t need too much care from here on out. Keep the water level at 2 inches (5 cm.) or so above the dirt. When the rice plants are 5-6 inches (12.5-15 cm.) tall, increase the water depth to 4 inches (10 cm.). Then, allow the water level to lower on its own over a period of time. Ideally, by the time you harvest them, the plants should no longer be in standing water.
If all goes well, rice is ready to harvest in its fourth month. The stalks will go from green to gold to indicate it is time to harvest. Harvesting rice means cutting and gathering the panicles attached to the stalks. To harvest the rice, cut the stalks and allow them to dry, wrapped in a newspaper, for two to three weeks in a warm, dry place.
Once the rice stalks have dried, roast in a very low heat oven (under 200 F./93 C.) for around an hour, then remove the hulls by hand. That’s it; you can now cook with your very own home grown, long grain brown rice.
