Answer:
Mean: 13
SD: 
Step-by-step explanation:
To find the mean, you have to add up all of them and divide by the number of them. The sum is 30+30+18 or 78, and there are 6 so the mean is 78 / 6 = 13.
To find the standard deviation, we need to first find the distance from them to the mean. These are 2, 3, 3, 3, 5, and 2. Square these values to get 4, 9, 9, 9, 25, and 4. Now we have to take the mean of this, which is 8+27+25=35+25=60, so the mean is 10 and now we take the square root so the SD is .
1. 24 cents/.24
2. Every 2 daisies to total amount/ 2,9
3. 10 juices
Yes. Because miles and kilometers are units of distance measurements. They have a fixed ratio, hence, there will always be a constant linear relationship between them. Or a constant slope. One mile is approximately 1.61 kilometers. So, just multiply any measurement of mile with 1.61 to get the distance in km.
When comparing to thing with same rate, set up a proportion:
Inches/cost
13/.78=33/x
(13)(x)=(.78)(33) [cross multiplied]
13x=25.74 [simplified]
13/13x=25.74/13 [division property]
x=1.98
33 inches of wire will cost $1.98.
Answer:
Algebra =
X/4 = -5/20
Simplify :
X/4 = -1/4
Of course, Will same x/4 = -1/4
<h3>Answer : X = -1</h3>
