Distance=√(x2-x1)²+(y2-y1)²
⇒√(9-9)² +(4+7)²
⇒√0²+11²
⇒11units
The percentage of runners having times less than 14.4 sec is 0.15%. Then the correct option is A.
<h3>What is normal a 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 times of all 15-year-olds who run a certain race are approximately normally distributed with a given mean (μ) = 18 sec and standard deviation (σ) = 1.2 sec.
The runners have times less than 14.4 sec.
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.
Then the Percentage will be

The answer to 26 is 11
The formula to find the area of a circle is A = r 2, or A = 2 x 2 in this case. That would be 12.57, or 13 if we’re rounding to the hundredth.
To find the parallelogram, it’s A = B h / A = 6 x 4 which is 24
You then subtract 13 from 24 to find the shaded region which is 11.
The relation is a function I believe so
The answer is 4.1
If the number is below 5, you round down, if it's 5 or above, you round up.
