There are four slices of pepperoni pizza and three slices of veggie pizza sitting on the counter. what is the probability of ran
Otrada [13]

Answer:

The probability of randomly choosing a slice of veggie pizza is 3/7

Step-by-step explanation:

Probability is the measure of uncertainty of any event. It is the ratio of number of favorable outcomes to the total number of possible outcomes. That is,

Probability, P(A) = (Number of a Favourable outcome) / (Total number of possible outcomes).

From the question,

There are four slices of pepperoni pizza and three slices of veggie pizza, this means

Total number of favourable outcomes = 4 + 3 = 7

The favourable outcome is the veggie pizza, therefore

Number of favourable outcome = 3

Hence,

Probability P (A) = 3 ÷ 7

P(A) = 3/7

The probability of randomly choosing a slice of veggie pizza is 3/7

A jet is coming in for a landing. It's currently 25,000 feet in
Mariana [72]

The angle of depression is 29.0521°. So it is a safe landing.

Step-by-step explanation:

Step 1:

The plane is flying at a height of 25,000 feet and 45,000 feet away from the landing strip. Assume it lands with an angle of depression of x°.

So a right-angled triangle can be formed using these measurements. The triangle's opposite side measures 25,000 feet while the adjacent side measures 45,000 feet. The angle of the triangle is x°.

To determine the value of x, we calculate the tan of the given triangle.

tanx = \frac{opposite side}{adjacent side}.

Step 2:

The length of the opposite side = 25,000 feet.

The length of the adjacent side = 45,000 feet.

tan x = \frac{25,000}{45,000} = 0.5555.

So x = 29.0521°. Since x < 30°, it is a safe landing.
