Answer:
65 degrees
Step-by-step explanation:
The degrees always has to add up to 180 degrees, so if you add 90 degrees and 25 degrees, you get 115 degrees. So since it has to be 180 degrees, you add 65 to 115, and you get 180 degrees.

4. A fruit stand sells boxes of apples. Each box weighs the same amount. The table shows the number of boxes and the total number of pounds. AppIGN Number of Boxes Tocal Number of Pounds И. 7 8 72 10 Which of the following correctly describes the relationship in the table? A. Number of boxes + 4 = total number of pounds B. Number of boxes x 9 + total number of pounds C. Number of boxes - 9 total number of pounds D. Number of boxes x 6 = total number of pounds
Answers
From the table it can be observed if we multiply the number of boxes by 9, then it gives total number of pounds for the corresponding number of boxes.
As 4 multiply by 9 is 36, which is total number of pounds for 4 boxes. In similar manner total number of pounds can be obtained for different number of boxes.
So answer is,
\(\text{ Number of boxes}\times9=\text{ total number of pounds}\)Option B is correct.

The angle measures for this problem are given as follows:
a = 62º.b = 118º.c = 62º.d = 62º.How to obtain the angle measures?The sum of the measures of the internal angles of a triangle is of 180º.
The triangle in this problem is ABC, hence the measure of a is obtained as follows:
a + 68 + 50 = 180
a = 180 - (68 + 50)
a = 62º.
c and d are corresponding angles to angle a, as they are on the same position relative to parallel lines, hence their measures are given as follows:
c = 62º.d = 62º.Angle b is a corresponding interior angle with angle a, hence they are supplementary and it's measure is given as follows:
a + b = 180

Find the equation of the line with slope 2/5 and y-intercept (0,−2).
Answers
Answer:
\(\boxed {\tt y=\frac{2}{5}x-2}\)
Step-by-step explanation:
If the slope and y-intercept is known, the equation of a line can be written using slope-intercept form.
\(y=mx+b\)
where m is the slope and b is the y-intercept.
We know that the slope is 2/5.
The y-intercept is (0,-2). For this form, we only need the y-coordinate, which is -2 in this case. Therefore, we can say the y-intercept is -2.
\(m=2/5 \\b= -2 \\\)
Substitute the values into the formula.
\(y=2/5x+ (-2)\)
\(y=2/5x-2\)
The equation of the line is y=2/5x-2

You are taking samples from a normally distributed population with mean 138 and standard deviation 14. Your batch size is 16. Let X-bar be the average of all 16 of your samples. What is the variance of X-bar?
Answers
The variance of X-bar is 12.25.
To find the variance of the sample mean (X-bar) for a normally distributed population, we can use the formula:
Variance of X-bar = (Population Variance) / (Sample Size)
In this case, the population mean (μ) is 138 and the standard deviation (σ) is 14. The population variance (σ^2) can be calculated as the square of the standard deviation, which gives us 14^2 = 196.
Since we are sampling with a batch size of 16, the sample size is also 16.
Now we can substitute these values into the formula:
Variance of X-bar = 196 / 16 = 12.25
Therefore, the variance of X-bar is 12.25.
It's important to note that the sample mean (X-bar) is an unbiased estimator of the population mean (μ). The smaller the sample size, the greater the variability of X-bar around the population mean.
As the sample size increases, the variance of X-bar decreases, indicating a more precise estimate of the population mean.

Jorge travels by taxi from his hotel to the airport. The taxi driver charges an initial fee of $3.50 plus $2.75 per kilometer. Which equation can
be used to find y, the total cost of the trip if x represents the number of kilometers of the trip ?
Answers
Answer:
C. \( y = 3.50 + 2.75x \)
Step-by-step explanation:
Initial fee charged by the taxi driver = $3.50
Fee charged per kilometer = $2.75
Number of kilometers of travel = x
Total cost charged for a trip = y = initial fee charged for renting a taxi + fee paid based on the number of kilometers travelled
Total cost of the trip can be expressed by the following equation:
\( y = 3.50 + 2.75x \)
The answer is C. \( y = 3.50 + 2.75x \).
An herbalist has 35 oz of herbs costing $3 per ounce. How many ounces of herbs costing $2 per ounce should be mixed with these 35 oz of herbs to produce a mixture costing $2.70 per ounce?
Answers
Based on the ounces of herbs and their cost, the amount of herbs that should be mixed to produce the mixture costing $2.70 per ounce is 21 ounces
How to find the ounces of herbs?Assuming that the amount of ounces needed to be mixed with the 35 ounce of herbs to produce a mixture costing $2.70 per ounce is x, then the formula would be:
Total cost = (2 × x) + (3 x 35) = 2.7 x (x + 35)
This can be expanded to be:
2x + 105 = 2.7x + 94.5

what is the equation for the perpendicular bisector of the line segment whose endpoints are (-7, 2) and (-1,-6)
Answers
The equation of the perpendicular bisector of the line segment with endpoints (-7, 2) and (-1, -6) is y = (3/4)x + 1.
To find the equation of the perpendicular bisector of a line segment, we need to determine the midpoint of the line segment and the slope of the line segment. The perpendicular bisector will have a negative reciprocal slope compared to the line segment and will pass through the midpoint.
Given the endpoints (-7, 2) and (-1, -6), we can find the midpoint using the midpoint formula:
Midpoint = ((x1 + x2)/2, (y1 + y2)/2)
Midpoint = ((-7 + (-1))/2, (2 + (-6))/2)
= (-8/2, -4/2)
= (-4, -2)
The midpoint of the line segment is (-4, -2).
Next, we need to find the slope of the line segment using the slope formula:
Slope = (y2 - y1)/(x2 - x1)
Slope = (-6 - 2)/(-1 - (-7))
= (-6 - 2)/(-1 + 7)
= (-8)/(6)
= -4/3
The slope of the line segment is -4/3.
Since the perpendicular bisector has a negative reciprocal slope, the slope of the perpendicular bisector will be 3/4.
Now, we can use the midpoint (-4, -2) and the slope 3/4 in the point-slope form of a line to find the equation of the perpendicular bisector:
y - y1 = m(x - x1)
y - (-2) = (3/4)(x - (-4))
y + 2 = (3/4)(x + 4)
y + 2 = (3/4)x + 3
y = (3/4)x + 1.

Answers
The price difference, which can then be used to determine the extra he can charge for the front row tickets.
To calculate the price difference between the front row and second row tickets, Jim should first identify the mean price of the second row tickets, P2. He can then compare the mean price of the second row tickets to the mean price of the front row tickets, P1. He can then calculate the price difference between the two rows by subtracting the mean price of the second row tickets from the mean price of the first row tickets, (P1-P2). This will give him the price difference, which can then be used to determine the extra he can charge for the front row tickets.
For example, if the mean price of the second row tickets, P2, is $15 and the mean price of the first row tickets, P1, is $20, then the price difference would be $5, meaning he can charge an extra $5 for the front row tickets.

The value of x in the given equation is -9/7.
Here, we are given an equation as follows-
\(e^{x-3} =(1/e^{6} )^{x+2}\)
The expression on the right hand side can further be simplified as follows-
\(e^{x-3} =(e^{-6} )^{x+2}\)
\(e^{x-3} =(e )^{-6(x+2)}\)
now since the bases on both sides are equal to e, we can simply equate the powers to form the following equation-
x - 3 = -6(x + 2)
Now, we solve the equation to find the value of x as follows-
x - 3 = -6x + -6*2
x - 3 = -6x -12
x + 6x = -12 + 3
7x = -9
x = -9/7
Thus, the value of x in the given equation comes out to be -9/7.
