Price of whisker cat food = $12.85
Price of power meow cat food = x
Whisker cat food = ⅓ * power meow cat food
12.85 = ⅓ x
X = 3 * 12.85

Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
What percentage of the books last more than 10 years?
As a proportion, this is 1 subtracted by the pvalue of Z when X = 10. So
has a pvalue of 0.655
1 - 0.655 = 0.345
So
34.5% of the books last more than 10 years.
Answer:
D: 200
Step-by-step explanation:
Given that
The DVD player shipped 960 players last month
There is a record that out of every 24 players, the 5 would be the repaired
So we need to find the number of DVD players were repaired in this 960 players
So
= 960 × 5 ÷ 24
= 200 players
Hence, the option is d.
To find 1/3 of 3/4 we divide the fraction by 3 which is equal to 1/4 or alternatively we can multiply the denominator by 3 which gives us 3/12 (1/4=3/12)
So 3/12 of the realesed fish are trout
To find 2/3 of 1/4 we need to first divide 1/4 by 3 which is equal to multiplying the denominator times 3 which gives us 1/12 and then we multiply by 2 which gives us 2/12
So 2/12 of the kept fish are trout
To find the total amount we add 2/12 and 3/12
3/12+2/12= 5/12
ANSWER:
5/12 of the fish she catches are trout
