Hi there!
Since 3 times a number must be smaller or equal to 18,
18 ÷ 3 = 6
any number equal to or smaller than 6 will be a solution to the inequality. I left this up for you to choose :)
Hope this helps!
Answer:
750 divided by 3.5%
Step-by-step explanation:
an increase in the number of predators C an increase in the number of parasites in the environment
Answer:
The number of times it would take more than 27 minutes to manufacture a pair of running shoes is 2.275 times or approximately 2 times per every 100 shoes
Step-by-step explanation:
The average time it takes to manufacture a pair of shoes = 21 minutes;
The standard deviation = 3 minutes
To find how often it takes more than 27 minutes to manufacture a pair of running shoes, we have;
Standard score, given as follows;
![Z=\dfrac{x-\mu }{\sigma }](https://tex.z-dn.net/?f=Z%3D%5Cdfrac%7Bx-%5Cmu%20%7D%7B%5Csigma%20%7D)
Where;
x = The raw score = 27 minutes
μ = The average score = 21 minutes
σ = The standard deviation = 3 minutes
From which we have;
![Z=\dfrac{27-21 }{3 } = 2](https://tex.z-dn.net/?f=Z%3D%5Cdfrac%7B27-21%20%7D%7B3%20%7D%20%3D%202)
Therefore, it is borderline unusual with a p value of P(z>2) = 1 - 0.97725 = 0.02275
Therefore, the number of times out of 100 that it would take more than 27 minutes to manufacture a pair of running shoes = 100 × 0.02275 = 2.275 times which is approximately 2 times in every 100 shoes.
