Bob travels within the speed limit.

For Bob to travel within the speed limit, the distance travelled by Bob in 3 hours must be less than the distance travelled gotten from the equation y = 70x.

<h3 /><h3>Maximum distance in 3 hours from the equation</h3>

With x = 3, y = 70(3) = 210 miles.

<h3></h3><h3>Bob's distance in 3 hours</h3>

From the straight line graph, Bob travels, 200 miles in 3 hours.

<h3 /><h3>Conclusion</h3>

Since this distance is less than that gotten from the equation, Bob travels within the speed limit.

So, Bob travels within the speed limit.

What is mean of 8,3,3,7 and 4

Marina86 [1]

The mean is the average of the numbers. To obtain it, you add all the numbers together and divide by the number of numbers. So:

8+3+3+7+4= 25

25:5= 5

So the answer is: the mean is 5.

A dog is leashed to the corner of a house with a 20 ft long leash. How much running area does the dog have? Round your answer to

11111nata11111 [884]

Answer:

The dog's running area is approximately 942 feet².

Step-by-step explanation:

The dog is leashed to a fixed point, the leash has a length of 20 ft, therefore he can rotate around that point at the maximum distance equal to the length of the leash. This pattern forms a circle, but there is an obstruction, which is the corner of the house. This obstruction takes an arc of the original circle, so the running area of the dog is the area of the whole circle minus the area of the arc formed by the corner of the house.

$\text{dog's area} = \text{circle's area} - \text{arc's area}\\\\\text{dog's area} = pi*(20^2) - \frac{90}{360}*pi*(20^2)\\\\\text{dog's area} = \frac{270}{360}*pi*(400)\\\\\text{dog's area} = 942.477\text{ feet}^2$

The dog's running area is approximately 942 feet².

A number cube was rolled as part of an experiment. The results are shown in the table. Explain how to find the experimental prob

pychu [463]

The experimental probability of rolling a 6 is 9/60 which can be determined by dividing the frequency of the observation 6 with the total frequency of the experiment.

<u>Step-by-step explanation:</u>

Experimental probability is different from theoretical probability because the former is obtained by experimentation while the latter is what we expect theoretically.When we take a number of observations, the experimental probability and theoretical probability need not be the same.

In this question we have to determine the experimental probability of 6. It can be determined by dividing the frequency of the observation 6 by the total frequency of the experiment.

frequency of 6=9

total frequency=frequency of 1+frequency of 2+frequency of 3+frequency of 4+frequency of 5+frequency of 6

=13+11+9+8+10+9

=60

P(6)=frequency of 6/total frequency

=9/60

A garden table and a bench cost $950 combined. The garden table costs $50 more than the bench. What is the cost of the bench?

snow_lady [41]

950 - 50 = 900
900 / 2 = 450
The bench cost $450 and the garden table cost $500
Your answer is $450
Hope this helps!
