Answer:
12.1%
Step-by-step explanation:
Given that:
Mean (μ) = 20.2 grams and standard deviation (σ) = 0.18 grams.
The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean. A positive z score means that the raw score is above the mean and a negative z score means that the raw score is below the mean. It is given by:
a) For x < 19.99 g:
From the normal distribution table, P(x < 19.99) = P(z < -1.17) = 0.1210 = 12.1%
The probability that a randomly chosen mouse has a mass of less than 19.99 grams is 12.1%
<u>Answer:</u>
- The solution of the equation is (-1,-2)
<u>Step-by-step explanation:</u>
- => x - 6y = 11
-6x + 6y = -6
- => 6(x - 6y) = 6(11)
-6x + 6y = -6
- => 6x - 36y = 66
-6x + 6y = -6
- => -30y = 60
- => y = -2
- => x - 6(-2) = 11
- => x + 12 = 11
- => x = -1
Hence, the solution of the equation is (-1,-2)
