Well he wants to buy 100 blue balloons so that would cost 100*0.6. The cost of white balloons(because they are half off) are w*0.3. He has a total of 150 dollars to we get 100*0.6+w*0.3=150 or 60+0.3w=150
Thus we get c

Answer:
By the Empirical Rule, 68% of IQ scores are between 87 and 121
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 104
Standard deviation = 17
Using the empirical rule, what percentage of IQ scores are between 87 and 121
87 = 104 - 1*17
So 87 is one standard deviation below the mean
121 = 104 + 1*17
So 121 is one standard deviation above the mean
By the Empirical Rule, 68% of IQ scores are between 87 and 121
Given :
There are 23 red shirts and 16 white shirts they will be put onto shelves in piles of 8.
To Find :
How many shirts will not fit evenly into 8 piles.
Solution :
We need to find the number of shirts which will not fit evenly into 8 piles.
What we need is the remainder of 23 divided by 8.
23 = 8×2 + 7
So, their are 7 shirts which will not fit evenly.
Hence, this is the required solution.
