You are at a pizza parlor that offers four toppings: anchovies, olives, pineapples, and sausage. how many different combinations

nata0808 [166]

The number of different combinations of these items that you can make if you choose four (4) toppings is equal to 1.

<h3>How to calculate the combinations of these items.</h3>

In order to determine the combinations of these items that this person can make, we would use this mathematical model known as combination.

Mathematically, combination is calculated by using this mathematical equation:

$_nC_r = \frac{n!}{r!(n-r)!}$

<u>Where:</u>

n is the total number of items.

r is the number of times of choosing items.

<u>Given the following data:</u>

Number of toppings = 4.

Let us assume you'll choose four (4) toppings.

Substituting the given parameters into the formula, we have;

⁴C₄ = 4/4

⁴C₄ = 1.

About 2% of the world's population have gray eyes. What is the probability that in a random sample of 1,500 people, more than 45

uranmaximum [27]

The probability that in a random sample of 1,500 people, more than 45 of them has gray eyes is 0.0028.

<h3>Probability:</h3>

First step is to find the mean

Mean(μ) = np = (0.02) (1500)

Mean(μ) = 30

Second step is to find the standard deviation

Standard deviation (σ)= √(npq)

Standard deviation (σ)= √(0.02 × 0.98 × 1500)

Standard deviation (σ)= 5.42

Third step is to find the z-score

z-score = (x − μ) / σ

z-score = (45 − 30) / 5.42

z-score = 2.77

Fourth step is to find the probability

Where:

P=Probability

P(z > 2.77) = 1 − P(z < 2.77)]

P(z > 2.77) = 1 − 0.9972

P(z > 2.77) =0.0028

Inconclusion the probability that in a random sample of 1,500 people, more than 45 of them has gray eyes is 0.0028.

A company produces light bulbs each week. written in scientific notation, which is the best estimate of how many light bulbs the

Radda [10]

The number of light bulbs that the firm will make in 9.36 × 10² weeks is 4.27 × 10^(6) bulbs.

<h3>What is Scientific notation?</h3>

This is known to be the method used to write a figure that very large or very small numbers.

Note that when the company makes a fixed quantity of light bulbs in a week, the amount of light bulbs can only be seen or found by multiplying that quantity by the number of weeks.

4.56 * 10^3 * 9.36 * 10^2

= 42.6816 * 10^5

= 4.26816 * 10^6.

Therefore, The company will produce 4.27 * 10^6 light bulbs in that time frame.

See full question below
