Need help asap! Please and thank you
Answer:
Choice A
Step-by-step explanation:
f(x) - g(x)
x^3 - 4x + 2 - (x - 2)^2
x^3 - 4x + 2 - (x^2 - 2x - 2x + 4)
x^3 - 4x + 2 - (x^2 - 4x + 4)
x^3 - 4x + 2 - x^2 + 4x - 4
x^3 - x^2 - 2
Which expression is equivalent to (see the picture)
A. 20x-21y +14
B. 20x + 11y + 14
C. 20x - 11y + 6
D. 20x + 21y +6
Answer:
A
Step-by-step explanation:
[tex]\frac{1}{5} (150x-80y+50-50x-25y+20)[/tex]
step 1 apply the 1/5 to everything that inside of the parenthesis
[tex]\frac{150x}{5} =30x\\\\\frac{-80y}{5} =-16y\\\\\frac{50}{5} =10\\\\\frac{-50x}{5} =-10x\\\\\frac{-25y}{5} =-5y\\\\\frac{20}{5} =4[/tex]
we now have 30x - 16y + 10 - 10x - 5y + 4
Step 2 combine like terms
30x - 10x = 20x
-16y - 5y = - 21y
10 + 4 = 14
we're left with 20x - 21y + 14 Which corresponds with answer choice A
Answer:
20x-21y+14
Step-by-step explanation:
1/5(150x-80y+50-50x-25y+20) is equal to 1/5(150x) + 1/5(-80y) + 1/5(50) + 1/5 (-50x) + 1/5(-25y) + 1/5(20)
So if we simplify, we would have 30x + (-16y) + 10 + (-10x) + (-5y) + 4, or 30x -16y + 10 -10x -5y + 4
When organizing the values by variable, the equation would look like this -
30x - 10x -16y -5y + 10 + 4
Combining like terms will result in 20x -21y + 14.
Hope this helps!

One-way ANOVA and two-way ANOVA are different because:__________
a. The single factor in one-way ANOVA has only one level.
b. Each factor in the two-way ANOVA has exactly two levels.
c. The one-way ANOVA concerns a single factor with multiple levels and the two ANOVA concerns two factors with also multiple levels.
d. The one-way ANOVA concerns a single factor with a single level and the two ANOVA concerns two factors with a single level each.
Answer:
c. The one-way ANOVA concerns a single factor with multiple levels and the two ANOVA concerns two factors with also multiple levels.
Step-by-step explanation:
The main difference between one way anova and two way anova is that one way anova has a single independent variable and two way anova has two independent variables.
The dependent variables may vary . They may be one , two or three. They do not affect the method used.
So one-way ANOVA concerns a single factor and the two ANOVA concerns two factors.
So the best choice is option c.
Put the steps in correct order to prove that if x is irrational, then 1/x is irrational using contraposition.
a. Substitute 1/x = p/q, to obtain x = 1/(1/x) = 1/(p/q) = q/p.
b. Hence x is rational.
c. If 1/x is rational, then 1/x = p/q for some integers p and q with q ≠ 0. Observe that p is not 0 either, because 1/x is not 0.
d. Observe that x is the quotient of two integers with the denominator nonzero.
Answer:
The correct order is:
a
c
d
b
Step-by-step explanation:
First, let's write 1/x in a convenient way for us:
a) Substitute 1/x = p/q, to obtain x = 1/(1/x) = 1/(p/q) = q/p.
Now we assume that 1/x is rational (we want to prove that this implies that x will be also rational and because we know that x is irrational assuming that 1/x is rational will lead to an incongruence), then:
c. If 1/x is rational, then 1/x = p/q for some integers p and q with q ≠ 0. Observe that p is not 0 either, because 1/x is not 0.
Now we know that we can write x as a quotient of two integers, we need to imply that, then the next one is:
d) Observe that x is the quotient of two integers with the denominator nonzero.
And that is the definition of rational, then we end with:
b) Hence x is rational.
Which is what we wanted to get.

Pls help Patricia can type 17 words in 15 seconds. What Is her rate in words per minute? Pls I need help I’m begging u have a good day pls help
Answer:
she can type 68 words every minute.
Step-by-step explanation:
In a minute there is 60 seconds so in 15 seconds she can type 17 words you
will do 17x4.
Answer:
68 words per minute
Step-by-step explanation:
Well, there are 60 seconds in a minute. 15 is 1/4 of 60.
Since 15 has to be multiplied by 4, so does 17.
17x4=68
So she types 68 words in a minute.

1. devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid. each side of the base of the pyramid is 6 cm and the height of the pyramid is 9 cm. to get the wax for the candle, devin melts cubes of wax that are each 4 cm by 4 cm by 4 cm. how many of the wax cubes will devin need in order to make the candle? show your work.
Answer:
1.6875
Step-by-step explanation:
Volume of a pyramid = 1/3 (l*w*h)
Volume = 1/3(6 * 6 * 9)
Volume = 2 * 6 * 9
Volume = 108 cm³
Volume of cube = s³ ; s = side length
Volume = 4³ = 4 * 4 * 4 = 64 cm³
Number of wax cube = Volume of pyramid / volume of cube
= 108 cm³ / 64 cm³
= 1.6875

Explain which event is more likely: rolling two dice and getting a total of 11, or, tossing a coin and getting three Heads in a row.
Answer:
The gambler's fallacy, also known as the Monte Carlo fallacy or the fallacy of the maturity of chances, is the erroneous belief that if a particular event occurs more frequently than normal during the past it is less likely to happen in the future (or vice versa), when it has otherwise been established that the probability of such events does not depend on what has happened in the past. Such events, having the quality of historical independence, are referred to as statistically independent. The fallacy is commonly associated with gambling, where it may be believed, for example, that the next dice roll is more than usually likely to be six because there have recently been fewer than the usual number of sixes.
The term "Monte Carlo fallacy" originates from the best known example of the phenomenon, which occurred in the Monte Carlo Casino in 1913.[1]

A multiple choice test contains 20 questions with answer choices A, B, C and D. Only one answer choice to each question represent correct answer. Find the probability that a student will answer exactly 6 questions correct if he makes random guesses on all 20 questions.
Answer:
0.1686 = 16.86% probability that a student will answer exactly 6 questions correct if he makes random guesses on all 20 questions.
Step-by-step explanation:
For each question, there are only two possible outcomes. Either the students answer it correctly, or he/she does not. The probability of answering a question correctly is independent of any other question. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
20 questions:
This means that [tex]n = 20[/tex].
Answer choices are A, B, C and D:
Only one is correct, so [tex]p = \frac{1}{4} = 0.25[/tex]
Find the probability that a student will answer exactly 6 questions correct if he makes random guesses on all 20 questions.
This is P(X = 6). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 6) = C_{20,6}.(0.25)^{6}.(0.75)^{14} = 0.1686[/tex]
0.1686 = 16.86% probability that a student will answer exactly 6 questions correct if he makes random guesses on all 20 questions.
The population of Farmersville can be modeled by the inequality y > 2,000x + 2,100, where x is the number of years since 2010. Will the population of Farmersville be greater than 6,300 in 2012?
Answer:
The population can be greater than 6,100 but less than 6,300, and thus, we cannot determine if the population of Farmersville will be greater than 6,300 in 2012.
Step-by-step explanation:
Inequality for the population of Farmsville:
The inequality for the population of Farmsville in x years after 2010 is given by:
[tex]y(x) > 2000x + 2100[/tex]
Will the population of Farmersville be greater than 6,300 in 2012?
2012 is 2012-2010 = 2 years after 2010, so we have to find y(2).
[tex]y(2) > 2000(2) + 2100[/tex]
[tex]y(2) > 6100[/tex]
The population can be greater than 6,100 but less than 6,300, and thus, we cannot determine if the population of Farmersville will be greater than 6,300 in 2012.

What is the simplest form of the expression below?
cot cos/sin . tan divided by sin/cos tan
sec
cot
csc
tan
Answer:
The answer is B, source: trust me
The simplest form of the given expression is Cot θ. Using trigonometric functions the complex expressions can be simplified into a simpler form.
What are the trigonometric functions?The trigonometric functions are as follows:
Sin θ = 1/Csc θ
Cos θ = 1/Sec θ
Tan θ = Sin θ/Cos θ
Cot θ = 1/Tan θ = Cos θ/Sin θ
Sec θ = 1/Cos θ
Cosec θ = 1/Sin θ
Now,
The given expression is
[{(Cot θ)(Cos θ)}/Sin θ × tan θ] ÷ [(Sin θ)/(Cos θ)(tan θ)]
Hence, Simplifying the first term:
[{(Cot θ)(Cos θ)}/Sin θ × tan θ]
⇒ (Cot θ) × (Cos θ/Sin θ) × tan θ
Since we know that;
⇒ Cos θ/Sin θ = Cot θ and
⇒ tan θ = 1/Cot θ
Hence,
⇒ (Cot θ) × Cot θ × (1/Cot θ)
⇒ Cot θ
And, Simplifying the second term:
[(Sin θ)/(Cos θ)(tan θ)]
⇒ (Sin θ/Cos θ) ×(1/tan θ)
⇒ (tan θ) × (1/tan θ)
⇒ 1
Thus, We get;
[{(Cot θ)(Cos θ)}/Sin θ × tan θ] ÷ [(Sin θ)/(Cos θ)(tan θ)]
= (Cot θ) ÷ 1
⇒ Cot θ
Therefore, The simplified expression is Cot θ.
