A container holds 2300 ounces fruit punch. A factory places the fruit punch into 32-ounce bottles, factory can produce 71 full bottles.
What is an ounce?The uncia, an ancient Roman unit of measurement, is the source of the ounce (/ans/), any of numerous possible measures of mass, weight, or volume.
Although it is frequently used outside of the Anglosphere, it is predominantly employed in the United States to measure packaged foods and food portions, postal items, the areal density of fabric and paper, boxing gloves, and other items.
Although the avoirdupois ounce is the standard unit of mass for most applications, the actual weight of precious metals like gold, silver, platinum, palladium, rhodium, etc. is measured in "troy ounces," which are equal to 31.1034768 g.
'Ounce' is also used in the following other contexts: A unit of measure for force is the ounce-force. A unit of volume is the fluid ounce.A multitude of distinct ounces measuring mass or volume have been employed historically by various trades at various times and in various countries.Solving the question,

An urn has 13 balls that are identical except that 6 are white and 7 are red. A sample of 7 is selected randomly without replacement.
What is the probability that exactly 5 are white and 2 are red?
What is the probability that at least 5 of the balls are white?
The probability that the exactly 5 are white and 2 are red is126/1716 and,
the probability that at least 5 of the balls are white is 133/1716
Given that:-
Total number of balls in the urn = 13
Number of white balls = 6
Number of red balls = 7
Number of randomly selected balls = 7
We have to find the probability that the exactly 5 are white and 2 are red and the probability that at least 5 of the balls are white.
Probability that exactly 5 balls are white and 2 are red, P(x = 5) = [tex]\frac{^6C_5*^7C_2}{^{13}C_7}[/tex] = 126/1716 = 21/286
We know that,
Probability that atleast 5 balls are white = P(x = 5) + P(x = 6)
We know that,
P(x = 6) = [tex]\frac{^6C_6*^7C_1}{^{13}C_7}[/tex] = 7/1716
Hence,
Probability that atleast 5 balls are white = 126/1716 + 7/1716 = 133/1716.

Consider the incomplete paragraph proof.
Given: P is a point on the perpendicular bisector, l, of MN.
Prove: PM = PN
Line l is a perpendicular bisector of line segment M N. It intersects line segment M N at point Q. Line l also contains point P.
Because of the unique line postulate, we can draw unique line segment PM. Using the definition of reflection, PM can be reflected over line l. By the definition of reflection, point P is the image of itself and point N is the image of ________. Because reflections preserve length, PM = PN.
From the unique line postulate, we can draw unique line segment PM and as we are given that P is a point on the perpendicular bisector I of MN, the proof below has shown that using the definition of reflection, point P is the image of itself and point N is the image of point M
How to Interpret the Perpendicular Bisector?We are given :
Point P is a point on the perpendicular bisector, l, of MN.
Now, we want to prove that PM = PN
A Reflection in transformation can be defined as the transformation in which the figure is the mirror image of the other figure. This means that every point is a mirror reflection of itself .
With the aid of the definition of reflection, we can form the statement that point P is the image of itself , and point N is the image of M .
The line l which is the perpendicular bisector of MN acts as a Line of symmetry or axis of reflection.
Finally, when talking about transformations, it is common knowledge that reflections preserve length which means that the required proof PM = PN will hold true
Therefore, we will conclude that point N is the image of M .

The unit rate of muffins per cup of almonds that the baker is for every 9 muffins, he uses 1 cup of almonds.
What is the unit rate?The unit rate is the ratio of a variable against another variable.
The unit rate explains the quantity relationship between the number of muffins produced and the cups of almonds used by the baker.
For this situation, a cup of almonds can make 9 muffins.
The total number of muffins made = 36
The total number of cups of almonds used = 4

What is percentage?
A number or ratio which can be expressed as just a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a portion per hundred. Per 100 is what the word percent means. The letter "%" stands for it. As in 0.6%, 0.25%, etc., percentages can also be expressed as decimals or fractions. The grades earned in any subject have been calculated in terms of percentages in academics. Ram, for instance, scored 78% on his final exam. This rate is computed based on Ram's overall grade point average (GPA) across all subjects.
For example 2% means [tex]\frac{2}{100}[/tex].

Cost last year = 24500
Cost today = 14300
Change in cost = 24500 - 14300

Using the normal distribution, it is found that:
a) The sampling distribution is approximately normal, with mean 45 and standard deviation 4.
b) The answer is not dependent on the sample size, as the underlying distribution is normal.
c) 0.0001 = 0.01% probability that the average is less than half an hour.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure X is above(in case the score is positive) or below(in case the score is negative) the mean. From the z-score table, the p-value associated with the z-score is found, which represents the percentile of the measure X.By the Central Limit Theorem, the sampling distribution of sample means of size n is approximately normal, with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex]. If the underlying distribution is normal, there are no sample size restrictions, while if the underlying distribution is not normal, the Central Limit Theorem is only valid for sample sizes of 30 and greater.For this problem, the parameters are given as follows:
[tex]\mu = 45, \sigma = 12, n = 9[/tex]
Hence the standard error of the approximately normal sampling distribution of sample means of size 9 is:
s = 12/sqrt(9) = 12/3 = 4.
As stated in the problem, the underlying distribution is normal, hence this is not dependent on the sample size.
For item c, the probability is the p-value of Z when X = 30, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem:
[tex]Z = \frac{X - \mu}{s}[/tex]
Z = (30 - 45)/4
Z = -3.75
Z = -3.75 has a p-value of 0.0001.
Hence the probability is of 0.0001 = 0.01%.

The support arm, AB, is
perpendicular to a line tangent to this curve on a roller coaster at the point of tangency B.
The equation of the tangent line to the curve at B is 3x + 2y = 28.
Find the equation of the support arm, AB.
B(4,8)
Lines perpendicular to tangents to curves, at
the point of tangency, are referred to as “normals.”
Answer:
[tex]y = \dfrac{2}{3}x + \dfrac{16}{3}}[/tex]
Step-by-step explanation:
The genera slope-intercept equation of a line is
y = mx + 8 where m is the slope and b the y-interecept
A perpendicular line will have a slope = -1/m ie the negative of reciprocal of the first line such that m x (-1/m ) = -1
The equation of the tangent line is
3x + 2y = 28.
1. Convert to slope-intercept form:
Subtract 3x from both sidesSo slope = -3/2
Reciprocal of -3/2 = -2/3
Negative of reciprocal = +2/3
Slope of a perpendicular line should be -1/3 and the resultant equation of the line(the support arm) should be:
y = (2/3)x + b
To calculate b for the complete line equation plug in the point B(4, 8) and solve for B
y = 8 when x = 4
=> 8 = (2/3)(4) + b
Switch sides: (does not change any signs)
8/3 + b = 8
Subtract 8/3 on both sides
b = 8 - 8/3
b = 24/3 - 8/3
b = 16/3
So equation of the support arm is
[tex]\boxed{y = \dfrac{2}{3}x + \dfrac{16}{3}}[/tex]

Step-by-step explanation:
Slope-intercept form:

m is the slope
b is the y-intercept
Parallel lines have the same slope, therefore we know that our new line will have the slope m = 4.
