The percentage of the snakes is longer than 16.6 in. with a mean of 15 in. and a standard deviation of 0.8 in. is 2.275%.
<h3>What is a normal distribution?</h3>
It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The lengths of a particular snake are approximately normally distributed with a given mean = 15 in. and standard deviation = 0.8 in.
Then the percentage of the snakes is longer than 16.6 in. will be
Then we have

Answer:
x = 4
Step-by-step explanation:
<em>To solve, we need to isolate </em><em>x</em><em>.</em>
<em>Start by moving the </em><em>20</em><em> to the other side by subtracting it from both sides.</em>
2x = 8
<em>Since </em><em>x</em><em> is being multiplied by </em><em>2</em><em>, we need to </em><u><em>divide</em></u><em> both sides by </em><em>2</em><em> to move it to the other side.</em>
x = 4

This can be solved by using a standard normal distribution table. The z-score for 34 pounds is 1, the reason being that 34 is one standard deviation above the mean of 28 pounds.
Can use the table to find the cumulative probability for z = 1.00 and post the result? If you do this we can do the next simple steps.
To find h(6), we must plug in 6 into the function.
h(x) = x^2 - 2x - 5
h(6) = 6^2 - 2(6) - 5
= 36 - 12 - 5
= 36 - 17 = 19
Answer:
Step-by-step explanation:
They both (36 and 45) go into 9. Divide them both by 9.
