Answer:
Step-by-step explanation:
since there are 205 calories in 5 crackers we can represent this as
205/5
we need to find how many calories are in one cracker, so lets take "x" as the # of calories in 1 cracker
so
cross multiply
5x=205
divide by 5 on both sides
x=41
41 calories in 1 cracker

Given that
the weight of football players is distributed with a mean of 200 pounds and a standard deviation of 25 pounds.
And we need to find What is the minimum weight of the middle 95% of the players?
Explanation -
Using the Empirical Rule, 95% of the distribution will fall within 2 times of the standard deviation from the mean.
Two standard deviations = 2 x 25 pounds = 50 pounds
So the minimum weight = 200 pounds - 50 pounds = 150 pounds
Hence the final answer is 150 pounds.
Answer:
120 units
Step-by-step explanation:
Answer:
c= 9b/a
Step-by-step explanation:
The statement "y varies directly as x," means that when x increases, y increases by the same factor. The statement "y varies inversely as x means that when x increases, ydecreases by the same factor.
Then, we can say that:
c ∝ b, thus c= kb and c = k/a.
Using both equations we have that:
c= kb/a
Given that a=6, b=22 and c=33 we have that:
33 = 22k/6
Solving for k:
k=9.
Then the equation that models the situation is:
c= 9b/a
