The statement that is equivalent to |6x-3|=3 is: 6x-3=3 or 6x-3=-3
For the equation to be true, two scenarios need to be considered:
When the expression 6x-3 is positive and equals 3:
6x-3 = 3
When the expression 6x-3 is negative and equals -3:
6x-3 = -3
By solving these two equations, we can find the equivalent statement:
Solving 6x-3 = 3:
Adding 3 to both sides gives us:
6x = 6
Dividing both sides by 6:
x = 1
Solving 6x-3 = -3:
Adding 3 to both sides gives us:
6x = 0
Dividing both sides by 6:
x = 0
Therefore, the equivalent statement to |6x-3|=3 is:
6x-3=3 or 6x-3=-3, which can be further simplified to:
6x-3=3 or 6x-3=-3

What do you add to 43/6 to make 7
Answer:
1/6 that's the answer
Step-by-step explanation:
so you do 43/6-7=43/6-42/6=1/6
Answer:
Actually the answer is -⅙
Step-by-step explanation:
43/6 written differently is 7 ⅙, because the fraction 42/6 is the same as 7 (42÷6=7). But since your number is 43/6 you get
7 1/6.
your original number is larger than 7 but the question was what number you have to "add" to get to 7. so they number has to be a negative number.
like this:
43/6 + (-1/6) = 42/6. which you rewrite now as
43/6 - 1/6 = 42/6. and I explained that 42/6 is the same as 7.

7 5/7 as a decimal please help
Answer:
the answer was 7.71
Step-by-step explanation:
hope this helps
A fraction is usually split into two parts: the first part is the number on top, called the numerator; and the second part is the number on the bottom, called the denominator. These are both separated by a line called the “divisor line”. We can use the division method help to solve this question: to get a decimal, simply divide the numerator 54 by the denominator 7 (which you can enter in any calculator):
54 (numerator) ÷ 7 (denominator) = 7.71
And finally, you get 7.71 as your answer when you convert 7 5/7 (or 54/7) to a decimal.
Answer:
7.71
Step-by-step explanation:
Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion. A person drilled a hole in a die and filled it with a lead weight, then proceeded to roll it 200 times. Here are the observed frequencies for the outcomes of 1, 2, 3, 4, 5, and 6, respectively: 29, 31, 49, 37, 26, 28. Use a 0.025 significance level to test the claim that the outcomes are not equally likely. Does it appear that the loaded die behaves differently than a fair die?
The loaded die appears to behave differently from a fair die.Based on the chi-square test, the loaded die does not exhibit equal probabilities for each outcome.
To test the claim that the outcomes of the loaded die are not equally likely, we can use the chi-square goodness-of-fit test. The null hypothesis (H₀) assumes that the outcomes are equally likely, while the alternative hypothesis (H₁) assumes that they are not equally likely.
Step 1: Set up hypotheses
H₀: The outcomes of the die are equally likely.
H₁: The outcomes of the die are not equally likely.
Step 2: Select the significance level
The significance level is given as 0.025, which means we have a two-tailed test and an alpha level of 0.025 for each tail.
Step 3: Compute the test statistic
We calculate the chi-square test statistic using the observed frequencies and the expected frequencies assuming equal probabilities for each outcome.
Expected frequencies (fair die):
1: 200/6 = 33.33
2: 200/6 = 33.33
3: 200/6 = 33.33
4: 200/6 = 33.33
5: 200/6 = 33.33
6: 200/6 = 33.33
Applying the chi-square formula, we get the test statistic:
χ² = ∑((observed - expected)² / expected)
Calculating this value, we get χ² ≈ 13.97.
Step 4: Determine the critical value
Since the significance level is 0.025 and the test is two-tailed, we divide the significance level by 2 to find the critical value associated with each tail. With 5 degrees of freedom (6 categories - 1), the critical value is approximately 11.07.
Step 5: Make a decision
The test statistic (13.97) is greater than the critical value (11.07), which leads us to reject the null hypothesis. Thus, we have evidence to suggest that the outcomes of the loaded die are not equally likely.
The loaded die appears to behave differently from a fair die.
In conclusion, based on the chi-square test, the loaded die does not exhibit equal probabilities for each outcome.

A bowl contains 6 red balls and 6 blue balls. A woman selects balls at random without looking at them. (a) How many balls must she select (minimum) to be sure of having at least three blue balls? (b) How many balls must she select (minimum) to be sure of having at least three balls of the same color?
There are 9 balls to be sure of having at least three blue balls, and there are 5 balls having at least three balls of the same color.
As per the question, the woman selects the balls at random without looking at them, so there is a possibility that the first 6 balls that she selects are all red. Then to have at least 3 blue balls she has to pick three balls from the rest of the 6 balls.
As all of them are blue only 3 picks are needed for that. Hence 6+3=9 balls she needs to pick to be sure of having at least 3 blue balls.
There are 2 colors of balls that are present in the bowl, Red and Blue. Now Consider there is a Red bucket and a Blue bucket outside the bowl and after picking each ball from the bowl, each ball must go to either of the buckets.
so apply the pigeonhole principle to be sure of having at least 3 balls of the same color
she needs to pick 2+2+1=5 balls from the bowl.

Mr. Waxman's delivery is an illustration of a linear function.
(a) Two points on the graph
The points are: (4,19) and (6,11)
(b) The slope of the graph
The slope (m) is calculated as:
\(\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}\)
So, we have:
\(\mathbf{m = \frac{11 - 19}{6- 4}}\)
\(\mathbf{m = \frac{-8}{2}}\)
\(\mathbf{m = -4}\)
The slope of the graph is -4
(c) The equation of the graph
In point-slope form, we have:
\(\mathbf{y -y_1 = m(x - x_1)}\)
So, we have:
\(\mathbf{y -4 = -4(x -19)}\)
In slope intercept form, we have:
\(\mathbf{y = -4(x -19) + 4}\)
Open brackets
\(\mathbf{y = -4x +76 + 4}\)
\(\mathbf{y = -4x +80}\)
The equation of the graph is: \(\mathbf{y = -4x +80}\)
(d) The value of the function at day 0
This means that x = 0
So, we have:
\(\mathbf{y = -4(0) +80}\)
\(\mathbf{y = 0 +80}\)
\(\mathbf{y = 80}\)
Hence, it will take 80 minutes to deliver the package on day 0

From the plot pointed, you go up three unit and 1 unit to the right to get back on the line. This is 3/1 or 3.
y - \(y_{1}\) = m( x - \(x_{1}\))
Replace m =3
Replace \(y_{1}\) = 2

Find the consumers surplus
The consumer surplus is approximately $145.83.
To find the consumer surplus, we first need to find the demand function's inverse, which gives us the willingness to pay for each unit of the product. The demand function is:
D(x) = √(739 - 3x)
Setting D(x) equal to the equilibrium price of $25, we get:
25 = √(739 - 3x)
Squaring both sides, we get:
625 = 739 - 3x
Solving for x, we get:
So at a price of $25 per unit, the consumer is willing to buy 38 units per month.
Now we can calculate the consumer's surplus.
The consumer\(x = (739 - 625) / 3 = 38\) surplus is the difference between the total amount that consumers are willing to pay for a certain quantity of a good and the total amount they actually pay. In this case, the consumer's surplus can be calculated as:
\(CS = \int_0^{38} [D(x) - 25] dx\)
where D(x) is the demand function, and the integral is taken over the range of 0 to 38, which represents the quantity demanded at a price of $25 per unit.
Evaluating this integral, we get:
\(CS = \int_0^{38} [\sqrt{(739 - 3x)} - 25] dx\\\\= [1/6 (739 - 3x)^{(3/2)} - 25x]_0^{38}\\\\= \$ 145.83\)
Therefore, the consumer surplus is approximately $145.83.

If a and b are two angles in standard position in Quadrant I, find cos(a-b) for the given function values. sin a=3/5and cos b=12/37
1) 153/185
2) 57/185
3) -57/185
4) -153/185
(Use the sum of identity for cosine)
The identity in question is
cos(a - b) = cos(a) cos(b) + sin(a) sin(b)
so that
cos(a - b) = 12/37 cos(a) + 3/5 sin(b)
Since both a and b lie in the first quadrant, both cos(a) and sin(b) will be positive. Then it follows from the Pythagorean identity,
cos²(x) + sin²(x) = 1,
that
cos(a) = √(1 - sin²(a)) = 4/5
and
sin(b) = √(1 - cos²(b)) = 35/37
So,
cos(a - b) = 12/37 • 4/5 + 3/5 • 35/37 = 153/185
