You can use the special right triangles for this equation. Since the side lengths are 3 and 4, the hypotenuse of the triangle would be 5, or you can use the equation a2 + b2 = c2, 3^2 + 4^2 = c2, 25 = c2, c=5

Answer:
The answer is explained below
Step-by-step explanation:
Given that:
mean (μ) = 7 and standard deviation (σ) = 1.5.
The z score is used in statistic used to measure the number of standard deviation by which the raw score is above or below the mean value. It is given by:

To find the Probability that x < 8.8, we first find the z score using:

From the z tables, P(x < 8.8) = P(z < 1.2) = 0.8849 = 88.49%
968.58=200.78+76.78w
-200.78
767.8=76.78w
/76.78
=10w
