Answer is From all those aforementioned, the true statement is: Thanh’s grade is 2.5 standard deviations below the mean of the test grades.
explanation
The z scores are standard deviations. If, for example, a tool returns a z score of +2.5, it means that the result is a standard deviation of 2.5. Very high or very low (negative) z scores associated
with very low p values are at the ends of the normal distribution.
Answer:
13(4+x)
=52+13x
Step-by-step explanation:
13 multiplies the 4 and x.
then 13 multiply 4 is 52 while 13 multiply x 13x.

Answer:
<u><em>C. </em></u>
<u><em> cm</em></u>
Step-by-step explanation:
<u><em>First, we can start out by stating that this is a </em></u><u><em>right triangle</em></u><u><em>, since </em></u><u><em>it has a right angle</em></u><u><em>, shown by the marker square in the corner of the triangle. </em></u><u><em>The x part, is called the hypotenuse</em></u><u><em>. When finding the value of the hypotenuse, we use a thing called the </em></u><u><em>Pythagorean Theorem.</em></u><u><em> This theorem is :</em></u>
<u><em>a^2 + b^2 = c^2</em></u>
<u><em>a is one side length, and b is the other. c is the hypotenuse.</em></u><u><em> To find x, the hypotenuse, we simply </em></u><u><em>plug in the values, and solve.</em></u>
<u><em>8^2 + 5^2 = c^2</em></u>
<u><em>64 + 25 = c^2</em></u>
<u><em>89 = c^2</em></u>
<u><em>To get c alone, we do the </em></u><u><em>square root of 89.</em></u>
<u><em></em></u>
<u><em> = c</em></u>
<u><em>9.43398113 = c</em></u>
<u><em>So, the answer is </em></u><u><em>C. </em></u>
<u><em> cm</em></u>
