What are the ratios for SIN A and COS A

Mathematics
1 answer:
miskamm [114]2 years ago
6 0

Answer:

A

Step-by-step explanation:

A good trick for trigonometric functions is to remember SOHCAHTOA:

Sin=<u>O</u>pposite over <u>H</u>ypotenuse

Cos=<u>A</u>djacent over <u>H</u>ypotenuse

Tan=<u>O</u>pposite over <u>A</u>djacent

The red arrows on the attachment indicate where opposite, hypotenuse, and adjacent are for angle A.

So in this case, the sin of angle A (opposite over hypotenuse) would be \frac{24}{26} and cos A (adjacent over hypotenuse) would be \frac{10}{26}.

I hope this helps!

denis23 [38]

Answer:

61,239,550

Step-by-step explanation:

We let the random variable X denote the IQ scores. This would imply that X is normal with a mean of 100 and standard deviation of 17. We proceed to determine the probability that an individual chosen at random from the population would be a genius, that is;

Pr( X>140)

The next step is to evaluate the z-score associated with the IQ score of 140 by standardizing the random variable X;

Pr(X>140)=Pr(Z>\frac{140-100}{17})=Pr(Z>2.3529)

The area to the right of 2.3529 will be the required probability. This area from the standard normal tables is 0.009314

From a population of 6,575,000,000 the number of geniuses would be;

6,575,000,000*0.009314 = 61,239,550
