Answer:
The variance of the total number of points she scores from these shots is 4.8951.
Step-by-step explanation:
For each 3-point shot that she takes, there are only two possible outcomes. Either she makes it, or she misses. This means that we can solve this problem using concepts of the binomial probability distribution.
Binomial probability distribution:
Probability of exactly x sucesses on n repeared trials, with p probability.
Has the variance given by:
In this problem, we have that:
She takes 7 shots, each one with a 37% probability of success. So 
. So:
This is the Variance of the number of shots that she makes. Each shot is worth three points. So the variance of the total number of points she scores from these shots is 3*1.6317 = 4.8951.
1\8 is actually 0.125 so I hope this helps
Answer:
[2×10*(-3) × (4×10*(4)] = 80
Step-by-step explanation:
First of all 0.002 is 10*(-3) and not 10(-2) , so you can eliminate the first 2 answers.
Second of all, according to the calculator the left equation is correct, while the right one isn't... so there you go
Glad to help :)
I think the answer is (-0.5, -1.5).
Answer:
Area is the measure of the amount of surface covered by something. Area formulas for different shapes are sometimes different, but for the most part, area is calculated by multiplying length times width. This is used when calculating area of squares and rectangles. Once you have the number answer to the problem, you need to figure out the units. When calculating area, you will take the units given in the problem (feet, yards, etc) and square them, so your unit measure would be in square feet (ft.2) (or whatever measure they gave you).
