What is this function written in vertex form? f(x) = (x + 2)2 + 3 f(x) = (x2 + 2x)2 + 3 f(x) = (x + 1)2 + 2 f(x) = (x + 3)2 + 2x

The function written in vertex form; f(x) = (x + 3)^2 + 2x. Hence, correct option is D.

### What is a quadratic equation?

A quadratic equation is the second-order degree algebraic expression in a variable.

The standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

x² + 2x + 3 = 0 is a quadratic equation.

An algebra tile configuration showing Only the Product spot is shown. 6 tiles are in the Product spot in 4 columns with 2 rows.

First row: 1 + x squared, 1 + x.

Second row: 1 + x, 3 +.

Then,

The factors of the polynomial are;

(2x + 3) (x + 1)

Thus, the function written in vertex form;

f(x) = (x + 3)^2 + 2x

Hence, correct option is D.

The popular candy Skittles comes in 5 colors. According to the Skittles website, the 5 colors are evenly distributed in the population of Skittle candies. So each color makes up 20% of the population. Suppose that we purchase a small bag of Skittles. Assume this size bag always has 40 candies. In this particular bag 10 are green. What is the probability that a randomly selected bag of this size has 10 or more green candies

27.76% probability that a randomly selected bag of this size has 10 or more green candies

Step-by-step explanation:

I am going to use the normal approximation to the binomial to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

The standard deviation of the binomial distribution is:

Normal probability distribution

Problems of normally distributed samples can be solved using the z-score formula.

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

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.

When we are approximating a binomial distribution to a normal one, we have that , .

In this problem, we have that:

So

What is the probability that a randomly selected bag of this size has 10 or more green candies

Using continuity correction, this is , which is 1 subtracted by the pvalue of Z when X = 9.5. So

has a pvalue of 0.7224

1 - 0.7224 = 0.2776

27.76% probability that a randomly selected bag of this size has 10 or more green candies

Step-by-step explanation:

The number x of green candies in a bag of 40 candies follows a binomial distribution, because we have:

• n identical and independent events: 40 candies
• a probability p of success and (1-p) of fail: a probability of 0.2 to get a green candie and 0.8 to doesn't get a green candie.

So, the probability that in a bag of 40 candies, x are green is calculated as:

Replacing, n by 40 and p by 0.2, we get:

So, the probability that a randomly selected bag of this size has 10 or more green candies is equal to:

Where

So, we can calculated P(0) and P(1) as:

At the same way, we can calculated P(2), P(3), P(4), P(5), P(6), P(7), P(8) and P(9) and get that P(x<10) is equal to:

Finally, the probability that a randomly selected bag of this size has 10 or more green candies is:

Which of the following statements is not​ true? A. If the probability of an event occurring is​ 1.5, then it is certain that event will occur. B. If the probability of an event occurring is​ 0, then it is impossible for that event to occur.

Therefore, we conclude that the statement in (A) is incorrect.

Step-by-step explanation:

We have the following sentences:

A) If the probability of an event occurring is​ 1.5, then it is certain that event will occur.

B) If the probability of an event occurring is​ 0, then it is impossible for that event to occur.

We know that the range of probability of an event occurring is in the segment [0, 1]. In statement under (A), we have the probability that  is equal to 1.5.

Therefore, we conclude that the statement in (A) is incorrect.

A floor plan is drawn using a scale of (3 cm)/(15ft) What length is represented by 1 centimeter ?

5 feet per 1 cm

Step-by-step explanation:

The answer is 5 feet.

Step-by-step explanation:

Set up a proportion.

3/15 = 1/x (x being the number of feet)

Cross multiply.

3x = 15

Solve for x. (divide both sides by 3)

x = 5

I hope this helps! :)
