Math help please What is the length of side BC of the triangle?

1 answer:

3 0

BC is 28 units long.

To find x, write the equation 4x - 7 = 2x + 7, as sides AC and AB are equal because the triangle is isosceles. The triangle is isosceles due to the base angles theorem. Once we get x, which is 7, we need to substitute it into the equation of BC. We then get 4(7), which equals 28 units.

Assume that a set of test scores is normally distributed with a mean of 70 and a standard deviation of 10. In what percentile is

vlabodo [156]

Given:
μ = 70, the mean
σ = 10, the standard deviation

The random variable is x = 65.
Calculate the z-score.
z = (x - μ)/σ = (65 -70)/10 = - 0.5

From standard ables, obtain
P(x<5) = 0.3085 ≈ 30%
The score of 65 is in the 30th percentile.

Answer: 30th
