Hi there!

• Base, b = 16
• Altitude, a = 5

Area of triangle = $\dfrac{1}{2}$ × b × a = $\dfrac{1}{2}$ × 16 × 5 = 40 sq. units.

Hence,
Option D. 40 sq. units is Correct

~ Hope it helps!

Answer
40

The formula to determine the area of the right triangle is a*b/2

First, let’s input the numbers into the formula.

16*5/2

Now we need to solve.

16*5= 80
80/2= 40

Therefore, the answer would be 40.

Assume that the random variable X is normally distributed, with mean 60 and standard deviation 16. Compute the probability P(X &

elixir [45]

Answer:

P(X < 80) = 0.89435.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

$\mu = 60, \sigma = 16$
