Answer: Rachel's prediction is faster than the actual unit rate, and Theadore's prediction is slower.
Answer:
The constant of proportionality gives you the price per unit at each store.
Step-by-step explanation:
If you assume that the price (y) is directly proportional to the amount (x) you get, the formula is
y = kx
where k is the constant of proportionality.
k = y/x
k has the units of cost per unit, for example, dollars per ounce.
The fewer the dollars per ounce, the better the deal you are getting.
If store A offers apple sauce at $1.29 for 25 oz and Store B offers apple sauce at $2.89 for 50 oz, which is the better deal?
At store A, k = $1.29/25 oz = $0.052/oz or 5.2¢/oz
At store B, k = $2.89/50 oz = $0.058/oz or 5.8¢/oz
The apple sauce is cheaper at Store A.
Well we are starting with a full pitcher(1)
1/4=2/8 & 1/8+2/8=3/8
then you subtract that from 1
1-3/8=5/8
Answer:
Step-by-step explanation:
60 sec= 1 min
60min=1hour
24hours=1day
7days=1week
52 weeks =1 year
24x7= 168hours in a week
168hours x 52 =8736 hours in a year
8736x60=524160mins
524160mins= 1 year
the heart beats 103680 in a year
the heart will beat 524160/103680=5.05555555556 in a minute
To calculate the mean absolute deviation, you first must find the mean of the data and then find the difference between each piece of data and the mean.
Please see the attached picture for the work.
The mean absolute deviation is approximately 1.48.
This means that the numbers of candies in the 10 bags are all very close to one another. There is not much variation.
