Answer:
a) Mean = 19
b) Standard Deviation = 3.08
Step-by-step explanation:
This is binomial probability distribution. We need to find the mean and standard deviation.
a) Mean
The formula for mean is:
Where n is the number of people, which is 38 and p is the probability of girl, which is 0.5
n = 38
p = 0.5
So,
Mean = 19
b) Standard Deviation
Standard deviation has the formula:
Where n and p are the same variables in part (a)
So we plug them in and find:
Standard Deviation = 3.08

To get to a pound, you must divide how many ounces you have by 16. So 96 divided by 16 = 6lbs. so that pumpkin would be $4 hope I helped :)
Answer:B
Step-by-step explanation:
Your equation would be y = -3x + 2.
A property of parallel lines is that they all have the same slope, which means that as the slope of y = 5 - 3x is -3 (because it is attached to the x), the slope of the parallel lines must also be -3.
You can finish the equation by seeing that the point they have given you is on the y axis, as x is 0, and so it is the y intercept for this line. This means that your final equation is y = -3x + 2.
I hope this helps
