Answer:

< 1 and < 3 are Corresponding Angles.

Step-by-step explanation:

Given the two parallel lines, <em>L1 </em>and <em>L2</em>, and the transveral across those two lines:

Then < 1 and < 3 are corresponding angles, since they are both on the same side of the transversal and in the same relative position. Corresponding angles are congruent, so < 1 and < 3 measure the same number of degrees.

Exhibit 5-9 Forty percent of all registered voters in a national election are female. A random sample of 5 voters is selected. R

Vikentia [17]

Answer:

Let X the random variable of interest "number of registered voters" in a random sample of n =5, on this case we now that:

$X \sim Binom(n=5, p=0.4)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

So then the best answer for this cas would be:

b. the number of registered voters in the nation

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest "number of registered voters" in a random sample of n =5, on this case we now that:

$X \sim Binom(n=5, p=0.4)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

So then the best answer for this cas would be:

b. the number of registered voters in the nation

After being rearranged and simplified, which two of the following equations could be solved using the quadratic formula? A) 5x^3

madreJ [45]

Answer:

B & D

Step-by-step explanation:

The quadratic formula can be used to solve for x for any quadratic. Recall a quadratic is any function whose highest exponent known as degree is 2. Looking at the answer selections, A has one term with exponent 3. This isn't possible in the formula. Looking at answer C, the term with exponent 2 has the same coefficient on each side of the equal sign. When it is rearranged these will cancel out no exponent of 2 will be in the equation anymore. Only B & D work after being rearranged and simplified

Using two or more complete sentences, describe and correct the error in the solution.

kakasveta [241]

Answer:

In the very first step, when they multiply both sides by 3 the -2y should become -6y but instead it stays as -2y. The correct solution would be:

9x - 6y =6

9x - 6y = 6

0 = 0

This means there are infinite solutions.
