elena-14-01-66 [18.8K]

Answer: 90.82%

Step-by-step explanation:

Given : The distribution of the amount of a certain brand of soda in 16 OZ bottles is approximately normal .

Mean : \mu=16.12\text{ OZ}

Standard deviation: \sigma=0.09\text{ OZ}

Let X be the random variable that represents the amount of soda in bottles.

Formula for z-score : z=\dfrac{x-\mu}{\sigma}

Z-score for 16 oz: z=\dfrac{16-16.12}{0.09}=-1.33

Using the standard normal z-distribution table , the probability that the soda bottles that contain more than the 16 OZ is given by :_

P(x>60)=P(z>-1.33)=1-P(x\leq-1.33)=1-0.0917591=0.9082409\approx0.9082\approx90.82\%

Hence, the percentage of the soda bottles that contain more than the 16 OZ advertised is 90.82% .

Eva is working two summer jobs, making $16 per hour tutoring and $8 per hour clearing tables. Last week Eva worked 3 times as ma
Volgvan

Eva spent 2 hours tutoring and 6 hours clearing tables.

Let x represent the number of hours Eva worked tutoring and y represent the number of hours Eva worked clearing tables.

Eva worked 3 times as many hours clearing tables as she worked hours tutoring hours and earned a total of $80. Hence:

y = 3x

-3x + y = 0    (1)

16x + 8y = 80    (2)

Solving equations 1 and 2 simultaneously gives:

x = 2, y = 6

Eva spent 2 hours tutoring and 6 hours clearing tables.
