If a triangle has a height of 14 inches and a base of 9 inches, what is its area?

Alexandra [31]

The formula for area of a triangle is

Area= 1/2*base*height

If you substitute values in for the base and height, you get the equation

Area = 1/2*14*9

When you multiply 1/2 by 14, you get 7. Substitute for this in your equation.

Area=7*9

Simplify by multiplying 7*9=63.

The area of the triangle is 63 inches.

Olenka [21]

Answer:

Lowest acceptable score = 121.3

Step-by-step explanation:

Mean test score (μ) = 115

Standard deviation (σ) = 12

The z-score for any given test score 'X' is defined as:

$z=\frac{X-\mu}{\sigma}$

In this situation, the organization is looking for people who scored in the upper 30% range, that is, people at or above the 70-th percentile of the normally distributed scores. At the 70-th percentile, the corresponding z-score is 0.525 (obtained from a z-score table). The minimum score, X, that would enable a candidate to apply for membership is:

$0.525=\frac{X-115}{12}\\X=121.3$
