If the ramp will be 3 feet above the ground and have a 4 foot Base , How long will the ramp be?
FinnZ [79.3K]

Answer:

5 feet long

Step-by-step explanation:

According to the Pythagorean Theorem, a^2 + b^2 = c^2  where "a" and "b" are the two legs of the right triangle and "c" is the hypotenuse.

We are trying to find the part that is at an angle, which is "c". So if we know "a" is "3 and "b" is 4, we can plug the values into the equation.

3^2 + 4^2 = c^2       plug in the values

9  +  16 = c^2           simply the two squared values

25 = c^2                   add the two values

5 = c                          take the square root of both sides

c = 5                          switch the values

Alligators captured in Florida are found to have a mean length of 2 meters and a standard deviation of 0.35 meters. The lengths
STALIN [3.7K]

Answer:

The correct option is (d). 2.15 meters.

Step-by-step explanation:

According to the given scenario, the approximate length of an alligator at the 67th percentile is as follows:

The length of an alligator is X \sim N(2,0.35) .

Let us assume the P_{67} be the 67th percentile

P(X

\frac{P_{67 - 2 }}{0.35} = 0.44\\\\P_{67} = 2.154

Hence, the correct option is (d). 2.15 meters
