Julie's first three test scores in biology<br> were 65, 90 and 73. What was her<br> average score?
dedylja [7]

Answer:Julie's average score was 76

Step-by-step explanation:

The formula for Average or mean is expressed as

Average = sum of terms / total number of terms.

Julie's first three test scores in biology were 65, 90 and 73.

The sum of the scores would be

65 + 90 + 73 = 228

The number of terms is the number of subjects. Therefore, the number of terms is 3. Therefore,

Average = 228/3 = 76

What is the length of VW?
Fudgin [204]
The answer is D. If you make a right triangle with the line, then you can use the Pythagorean theorem (a^2+b^2=c^2) to solve for VW. The vertical line would be 4 units and horizontal line would be 2 units. Therefore 4^2+2^2=20 take the square root of 20 and that is the answer.
