Answer:

1098.0266 square meters.

Step-by-step explanation:

Area of a circle is pi times radius squared. We know the diameter, witch is twice the radius. Usually we use 3.14 as pi, but it can also be 22/7. If you have to show your work, try looking for if it asks for pi in the decimal or fraction form. Can I get brainliest?

Work out Ryan’s average speed for his total return journey detailing how you worked it out.
pickupchik [31]

Answer:

For the return, i guess that you say in the interval between 15:40 and 15:45, that is the moment where he goes back to his home, and pass through the local shop.

Ok, in the graph we can see pairs (time, position)

The average speed can be obtained with two of these pairs, and the average speed is:

As = (position2 - position1)/(time2 - time1)

In this particular case, we have the pairs:

(15:40, 900m) and (15:45, 400m)

(i guess that the distance is in meters)

Then the average speed is:

As = (900m - 400m)/(15:45 - 15:40)

and 15:45 - 15:40 = 0.5 minutes.

As= 500m/5 min = 100 m/min

This means that the average speed in this return is 100 meters per minute

Solve for the variable x.
inna [77]

Answer:

<u>x = 5</u>

Step-by-step explanation:

Equating the terms :

  • x + 3 = 2x - 2

Add 2 on both sides :

  • x + 3 + 2 = 2x - 2 + 2
  • x + 5 = 2x

Subtract x from both sides :

  • x + 5 - x = 2x - x
  • <u>x = 5</u>

A sample of n = 9 college students is used to evaluate the effectiveness of a new Study Skills Workshop. Each student’s grade po
Vinil7 [7]

Answer:

80% Confidence interval:  (0.4603,0.7397)

Step-by-step explanation:

We are given the following in the question:

Sample mean, \bar{x} = MD = 0.60 points

Sample size, n = 9

Sample variance =  0.09

Sample standard Deviation =

=\sqrt{\text{Sample Variance}} = \sqrt{0.09} = 0.3

80% Confidence interval:  

\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}  

Putting the values, we get,  

t_{critical}\text{ at degree of freedom 8 and}~\alpha_{0.20} = \pm 1.397  

0.60 \pm 1.397(\frac{0.3}{\sqrt{9}} ) = 0.60 \pm 0.1397 = (0.4603,0.7397)
