Answer:
s=10
Step-by-step explanation:
Basically, the range rule-of-thumb is that the range is generally about four times the standard deviation.
<u>First, we find the range:</u>
Range=Maximum-Minimum
Range=100-60
Range=40
<u>Next, divide the range by 4 to get the standard deviation</u>
Range=4(Standard Deviation)
40=4(Standard Deviation)
10=Standard Deviation
Therefore, s=10, which is the standard deviation
Answer:
For each sandwich, spread 2 tablespoons peanut butter onto 1 slice of bread. Spread 1 tablespoon jelly onto another slice of bread.
Heat 12-inch skillet or griddle over medium heat.
Place 2 sandwiches into skillet. Cook, turning once, 4-6 minutes or until golden brown and peanut butter is melted.
Step-by-step explanation:
If you graphed the equation: y = 5
You would put a straight line going horizontally through 5. Like this picture shows. If it were x = 5, for example, then it would go up and down through 5.
Let me know if this helped! Have a nice day!

Step-by-step explanation:
Answer:
7 + (x/2) = 9.2
solve for x.
Step-by-step explanation:
We're hanging weights from a spring and measuring the distance of stretch. This is how those vegetable scales in grocery stores work (kind of). We know that the spring, with no weight, is 7 cm. So it can't get any shorter than this. We also know that for every kg of mass added, the spring stretches 0.5 cm. So, if you hung 3 kg of weight, the spring would have to stretch 0.5 * 3 = 1.5 cm. Add to that the 7 cm that it was originally and we have 8.5 cm of total length.
The second question is essentially answered by the first because the blank equation given in the first says
(initial length) + 1/2 * (mass added) = (total length)
The initial length will be a constant 7, the mass added we're told is to be x and the total length is to be y. Put those in their places and graph accordingly.
3) This is simply asking you to do what you've been doing, but in reverse. We have an equation, so we can now just plug in what we know and solve for what we don't.
7 + (x/2) = y
y = 9.2 in this case because it's representative of the total length, so we have
7 + (x/2) = 9.2
Now just solve for x.
