Determine whether and are parallel, perpendicular, or neither. W(–4, 5), X(8, –1), Y(6, –2), Z(1, –7)

Answers

Answer 1

Answer:

Answer: The question is that of Line WX and YZ are parallel or perpendicular, not WZ and XY unlike the other given answer.

THE ANSWER IS NEITHER

Step-by-step explanation:

See moc up i made. The two lines don't even intersect, I.E the answer is neither!

Answer 2

Answer:

Answer:

You have not mentioned the joining points so I have joined the points WZ and XY and plotted in the graph. It seems that the lines WZ and XY are perpendicular.

If h(x) = 6 - X, what is the value of (hoh)(10)?

16.

Answers

For the function h(x) = 6 - X the value of (hoh)(10) is 10.

What is a function?

A relation is a function if it has only One y-value for each x-value.

The given function is h(x) = 6 - X

We have to find the value of (hoh)(10)

The composite function (hoh)(10) can be written as h(h(10))

h(h(10))

Plug in the value 10 in place of x

=h(6-10)

=h(-4)

Now let us find h(-4)

=6-(-4)

=6+4

=10

Hence, for the function h(x) = 6 - X the value of (hoh)(10) is 10.

Rewrite the expression as a product using GCF and distributive property= 27+45= Explain your answer.

Answers

Step-by-step explanation:

The greatest common factor (GCF) of 27 and 45 is 9.

27 + 45

9 (3 + 5)

9 (8)

Final answer:

The expression 27 + 45 is rewritten using the Greatest Common Factor (GCF) and the distributive property as 9*(3 + 5) = 72.

Explanation:

The given expression is 27 + 45. To rewrite this using the Greatest Common Factor (GCF) and the distributive property, we first find the GCF of the two numbers. The GCF of 27 and 45 is 9. We then divide each number by the GCF and rewrite the expression using the distributive property.

So, 27 + 45 = 9*(3 + 5) = 9*8 = 72.

The above step is the application of the distributive property, where a*(b + c) = ab + ac.

Consider a disease whose presence can be identified by carrying out a blood test. Let p denote the probability that a randomly selected individual has the disease. Suppose n individuals are independently selected for testing. One way to proceed is to carry out a separate test on each of the n blood samples. A potentially more economical approach, group testing, was introduced during World War II to identify syphilitic men among army inductees. First, take a part of each blood sample, combine these specimens, and carry out a single test. If no one has the disease, the result will be negative, and only the one test is required. If at least one individual is diseased, the test on the combined sample will yield a positive result, in which case the n individual tests are then carried out. [The article "Random Multiple-Access Communication and Group Testing"† applied these ideas to a communication system in which the dichotomy was active/idle user rather than diseased/nondiseased.] If p = 0.15 and n = 5, what is the expected number of tests using this procedure? (Round your answer to three decimal places.)

Answers

Answer:

The expected number of tests, E(X) = 6.00

Step-by-step explanation:

Let us denote the number of tests required by X.

In the case of 5 individuals, the possible value of x are 1, if no one has the disease, and 6, if at least one person has the disease.

To find the probability that no one has the disease, we will consider the fact that the selection is independent. Thus, only one test is necessary.

Case 1: P(X=1) = [P (not infected)]⁵

= (0.15 - 0.1)⁵

P(X=1) = 3.125*10⁻⁷

Case 2: P(X=6) = 1- P(X=1)

= 1 - (1 - 0.1)⁵

P(X=6) = (1 - 3.125*10⁻⁷) = 0.999999

P(X=6) = 1.0

We can then use the previously determined values to compute the expected number of tests.

E(X) = ∑x.P(X=x)

= (1).(3.125*10⁻⁷) + 6.(1.0)

E(X) = E(X) = 6.00

Therefore, the expected number of tests, E(X) = 6.00

Answers

Final answer:

600 liters of soda is equal to 600,000 milliliters.

Explanation:

To convert liters to milliliters, we multiply by 1000 since there are 1000 milliliters in one liter. So, 600 liters of soda is equal to 600,000 milliliters.
