The line segment of length 3 1/2 is sketched with mid pint at -1 and attached
What is a line segment?A line segment in geometry has two different points on it that define its boundaries.
A line segment is sometimes referred to as a section of a line that links two places. The difference between a line and a line segment is that a line has no endpoints and can go on forever in either direction.
How to make the line segmentThe endpoints is important before a line can be defined as a line segment, however the midpoint will be essential in calculating for the endpoints
The mid point of the line is given to be -1
the other ends will be 3 1/2 /2
1.75
from -1 add and subtract 1.75 to get the endpoint's
-1 + 1.75 = 0.75
-1 - 1.75 = 2.75
each unit on the number line is 0.3333
to get 0.75 from 0 count two units to give 0.6667 then a bit more to get to 0.75
to get 2.75 from 2 count two strokes to get to 2.6667, then add a little more to get 2.75

Answers
Answer:
-8b^2 + 4b
Step-by-step explanation:
To simplify the expression (-6b^2 2b-1) + (-2b^2 + 4b), we need to combine like terms.
First, let's distribute the negative sign to the terms inside the first set of parentheses:
(-6b^2) + (-2b^1) = -6b^2 - 2b^1
Now let's combine the terms inside the second set of parentheses:
(-2b^2) + (4b) = -2b^2 + 4b
Finally, let's add the two expressions:
(-6b^2 - 2b^1) + (-2b^2 + 4b) = -6b^2 - 2b^1 - 2b^2 + 4b
Simplifying, we get:
-8b^2 + 4b = -8b^2 + 4b
The final simplified expression is: -8b^2 + 4b.

Given the point with Cartesian coordinates, (3√3,−3), find the polar coordinates of the point.
Answers
Answer: (6,11π/6).
Step-by-step explanation:We need to find the radius r and the angle θ. Remember that r2=x2+y2, so
because of the signs of x and y, our angle is in quadrant IV. Therefore, we find that θ=11π/6.
So the final answer is (6,11π6).
The A+ Cell Company charges $40 per month and $0.30 per minute for each additional minute over 500 minutes. The cost can be written as a linear function, C(x)=0.3x+40, where x is the number of minutes over 500. If the company were to increase the $40 charge to $50, how would the graph of this function change?
The graph will move _____ units.
answers are: up 10, down 10, left .10, right .10
Answers
Answer:
up 10
Step-by-step explanation:
The function would change from
C(x) = 0.3x + 40
to
C(x) = 0.3x + 50
The change is only to the y-intercept, so the graph of the function will move up 10.

3x² - 7 = 140
Answers
Answer:
x=7,−7
Step-by-step explanation:
In order to find the value of x in this quadratic equation we first need to make the equation equal 0 by getting rid of the 140. We do this by subtracting 140 on each side.
3x² - 7 = 140
3x² - 147 = 0
Now we solve as a regular quadratic formula
x= \(x = \frac{-(0) +- \sqrt{0^{2} - 4(3)(-147) } }{2(3)}\)
\(x = \frac{0 +- \sqrt{1764} }{6}\)

Find the equation of the line that is parallel to the line x + 5y = 10 and passes through the point (1, 3). A) y 1 16 5 5 5 B) y = -5x - 16 C) y = 5x + 10 D) y=x-2
Answers
First, we need to take the equation x + 5y = 10 and solve for y as:
\(\begin{gathered} x+5y=10 \\ 5y=10-x \\ y=\frac{10-x}{5} \\ y=2-\frac{1}{5}x \end{gathered}\)Since the coefficient of x is -1/5, the slope of this function is -1/5 and the slope of a parallel line is also -1/5.
Then, with the slope m and a point (x1, y1), we can find the equation of a line as:
\(y-y_1=m(x-x_1)\)So, replacing m by -1/5 and (x1, y1) by (1, 3), we get:
\(\begin{gathered} y-3=\frac{-1}{5}(x-1) \\ y-3=\frac{-1}{5}x-\frac{1}{5}\cdot(-1) \\ y-3=\frac{-1}{5}x+\frac{1}{5} \\ y=\frac{-1}{5}x+\frac{1}{5}+3 \\ y=\frac{-1}{5}x+\frac{16}{5} \end{gathered}\)Answer: y = -(1/5)x + (16/5)

Hideki rode his bicycle to his friend Mario house
Answers
Hideki's average rate of riding his bicycle is \(5/3\)miles per hour.
What is Hideki's average rate of riding his bicycle?Let us represent rate of riding the bicycle with x miles per hour.
Given:
Distance from his house to his friend's house = 1 mile
Distance from his friend's house to school = 12 miles
Time taken to get to school = 3/5 hour
We will set an equation based on distances and rates:
Distance = Rate × Time
Plugging values:
1 = x * (3/5) (For the distance from Hideki's house)
Multiply both sides by 5:
5 = 3x
x = 5/3.
Full question:
Hideki rode his bicycle to his friend's house, a distance of 1 mile. Then his friend's mother drove them to school, a distance of 12 miles.

Select the graph for the solution of the open sentence. Click until the correct graph appears. |x| + 3 > 3
Answers
The correct graph of the inequality ( |x| + 3 > 3) is attached accordingly.
Here is how the above was solvedRecall that the absolute value (or modulus) of a real number x is its non-negative value regardless of its sign. For example, 5 has an absolute value of 5, and 5 has an absolute value of 5.
A number's absolute value can be conceived of as its distance from zero along the real number line.
So, given |x| + 3 > 3
Add minus three to both sides
|x| + 3 + (-3) > 3 + (-3)
|x| > 0
Thus, the absolute value of x is
x > 0 or x < -0
put in the form of inequality, we have

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?
Answers
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.
