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%
<span>y-10 = -5/4x + 30/4 represents a linear function; we know that because both x and y have the power 1.
We could put this equation into one of several forms.
Suppose we wanted to put it into slope-intercept form. Then </span><span>y-10 = -5/4x + 30/4 becomes y = 10 + 30/4 - (5/4)x, or y = 35/2 - (5/4)x. Thus, this line has the slope -5/4 and the y-intercept (0, 35/2).
If this isn't quite what you wanted, then please share the instructions.

Answer:
40
Step-by-step explanation:
So far, the Lengths we have are
4, 4, 8, and 4
for the bottom length, add 8 and 4
For the side length, and 4 and 4
so the lenghts are 4, 4, 8, 4, 8, and 12
4+4+8+4+8+12=40
