To find out how much is needed for 1 you will need to divide each given value by 4:
12 marshmallows / 4 = 3
8 graham crackers / 4 = 2
4 smores / 4 = 1
you then need to multiply each value by 3 :
3 marshmallows x 3 = 9
2 graham crackers x 3 = 6
1 smore x 3 = 3
therefore the answer would be :
9 marshmallows
6 graham crackers
hope this helps you
Answer:
b) equals 20 hours.
Step-by-step explanation:
The sampling distribution of means refers to the distribution of all the possible sample means, with a certain sample size (in this case, n=100) extracted from the population.
The sampling distribution of the means is equal to the population mean. That does not mean that every sample will result in a mean equal to the population, but that the population of sample means will have an average of 20 hours.
Answer:
x=2
Step-by-step explanation:
We are given that the length of the line segment AC is 39. We are also given the length segment of AB = 9x+7 and the line segment BC is equivalent to -3x+20.
We also know based off the diagram that AC = AB + BC. We can use substitution to set up an equation:
AB+BC=AC
9x+7-3x+20=39
Combine like terms
6x+27=39
Subtract 27 from both sides
6x=12
Divide both sides by 6 to isolate x
x=2
