Answer:
y=96
Step-by-step explanation:
y=4^2(2+4)
y=16(2+4)
y=16(6)
y=96
Refer to the diagram shown below.
Assume that approximately all the data is contained under the probability distribution curve within 3 standard deviations from the mean. It is actually 99.7%.
Therefore,
bin #1 corresponds to μ-3σ,
bin #11 corresponds to μ,
bin #21 corresponds to μ + 3σ.
Let x be the random variable for bin 17.
Then by interpolation,
The z-score for x is
The probability corresponding to bin #17 is (from standard tables)
P(z≤1.8) = 0.964
Therefore if there are 1000 balls, the sum of the balls in bins 1 to 17 is
0.964 * 1000 = 96.4 ≠ 96 balls.
Answer: 96 balls

Divide the amount of money earned by the amount she got from every house.
780 / 5 = 156
156 out of 278 houses payed money. Subtract to see how many did not pay money
278 - 156 = 122
Hannah did not collect money from 122 of the houses in her neighborhood.
