Based on the box plot concept and the available options, the box plot that correctly represents the data is option A.
What is Box Plot?Box plot is a term that is used to describe the box and whisker plot which shows the five-number summary of a set of data.
Generally, this five-number summary is the minimum, first quartile, median, third quartile, and maximum.
Therefore, to get the right box plot we have the following steps.Make a box plot of the data.
Step 1: Order the data from smallest to largest. We have 52, 54, 56, 58, 60, 62, and 64Step 2: Find the median. The median is the middle number: 58Step 3: Find the quartiles. The first quartile is the median of the data points to the left of the median: 54. The third quartile is the median of the data points to the right of the median: 62Step 4: Complete the five-number summary by finding the min and the max. The min is the smallest data point, which is 52. The max is the largest data point, which is 64The five-number summary is: 52, 54, 58, 62, 64.Let's make a box plot for the same dataset from above.
Step 1: Scale and label an axis that fits the five-number summary.
Recall that Q1 = 54, the median is 58, and Q3 = 62
Also, the min is 52 and the max is 64.
Therefore, when we draw the box from Q1 to Q3 and from Q1 to the min, and from Q3 to the max, we have option A as the answer.

9. (-4) + 3 x ²7-3)-(-1)
Answer:
First, we need to simplify the expression by combining like terms. We have -4 + 3x^2-3 and -1. We can combine the like terms -4 and -1 to get -5.
Now, the expression can be rewritten as -5 + 3x^2-3. Next, we need to use the order of operations to evaluate the expression. The first step is to simplify any terms within parentheses, so we simplify 3x^2-3 to 3x^2-3 = 3x^2-3.
Now, the expression can be rewritten as -5 + 3x^2-3. The next step is to perform any multiplication or division, so we multiply 3 with x^2 to get 3x^2.
The expression is now -5 + 3x^2. The last step is to perform any addition or subtraction, so we add -5 and 3x^2 to get 3x^2-5.
Therefore, the answer to the expression is 3x^2-5.

What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given:
The measures of two supplementary angles total 180 degrees.
The measure of angle y is 65 degrees less than the measure of angle x.
Let the measure of angle y is m∠y.
And the angle measure of x is m∠x.
So,
m∠x + m∠y = 180° {equation 1}
And according to the question,
m∠y = m∠x - 65° {equation 2}
Substituting the value from equation 2 to equation 1,
2m∠x = 180 + 65
m∠x = 245/2
m∠x = 122.5°
And m∠y = 122.5 - 65
m∠y = 57.5°
Therefore, the angle measures are m∠x = 122.5° and m∠y = 57.5°.

Joshua watched 1 3 of a movie in the morning, and he watched some more at night. By the end of the day, he still had 1 5 of the movie left to watch. How much of the movie did Joshua watch at night
We can start solving the problem by using algebra. Let x be the total length of the movie in minutes. Then we know that:
1/3 of the movie is x/3 minutes.
1/5 of the movie is x/5 minutes.
We are told that Joshua watched 1/3 of the movie in the morning and had 1/5 of the movie left to watch at night. Therefore, we can set up the equation:
x/3 + y = x/5, where y is the length of the movie that Joshua watched at night.
We can then solve for y by isolating it on one side:
y = x/5 - x/3
We know that 1/3 + 1/5 = 8/15.
We can simplify by multiplying both sides of the equation by 15:
y = (8/15)*x = 8x/15
We can conclude that Joshua watched 8/15 or approximately 53.33% of the movie at night.
what is the equation of a line in point-slope form with a slope if 1/2 and the point (5,-2) is on the line?
The equation of the line in slope intercept form is y = 1 / 2x - 9 / 2.
How to represent equation in slope intercept form?The equation of a line can be represented in slope intercept form as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the slope of the line is 1 / 2 and the line passes through (5, -2).
Hence,
y = 1 / 2 x + b
let's find the y-intercept using (5, -2)
Therefore,
-2 = 1 / 2 (5) + b
b = -2 - 5 / 2
