Answer:
Subjective probability.
Step-by-step explanation:
We have been told that Argelia has been fishing many times on the Broad River, but she has never recorded the number or types of fish she caught on her trips. She also has no idea how many fish are in the Broad River.
Since we know that subjective probability is a probability based on an individual's personal judgement or past experiences about happening of some specific event. Subjective probability contains no formal calculations.
Upon looking at this problem we can see that this is indicating about subjective probability as this is based on Argelia's past experiences and she has never recorded the number or types of fish she caught on her trips.
Therefore, Argelia used subjective probability to tell Adam about having a 90% chance of catching a fish.
Four neighborhood children opened their own lemonade stand. The table shows the sales information for each stand, in glasses of lemonade. What was the largest fraction of sales of the stands' inventory?
A. 1⁄2
B. 4⁄7
C. 3⁄4
D. 7⁄12
Answer:
Option C is the answer.
Step-by-step explanation:
Given that four neighborhood children opened their own lemonade stand. The sales by the four were as follows:
A. 1⁄2
B. 4⁄7
C. 3⁄4
D. 7⁄12
We cannot compare these sales as such since they have different denominators.
To compare we find the Least common denominator for all the four first.
2,7,4,12 have lCD = 12(7) = 84
Now make equivalent fractions for all the four.
A. 1⁄2 = 42/84
B. 4⁄7 = 48/84
C. 3⁄4 = 63/84
D. 7⁄12 = 49/84
Now since denominator is the same we compare and find that
C =63/84 is the largest value.
Hence Option C is the answer.
A movie cost $3,254,107 to produce.What digit is in the hundred thousands place?
The digit that we have is 3,254,107.

Step-by-step explanation:
Why do the ratios of sine and cosine depend upon the angle being a part of a right triangle?
Step-by-step explanation:
Think of a right triangle (refer the attached image). If you increase or decrease the length of one of its legs, while keeping the other leg the same (the hypotenuse will increase as well) here we have increased the length of the perpendicular side. You can see that the *subtending* angle (the angle which is opposite to the increasing leg, x) gets larger, while the *adjacent* angle (the angle with the increasing leg as one of its rays) will decrease.
and we know that:
[tex]\sin x=\frac{AB}{AC}[/tex] and [tex]\cos x=\frac{BC}{AB}[/tex] in both the cases the variation of AB is causing the angles to change hence, the ratios of sine and cosine depend upon the angle being a part of a right triangle.
An investment firm wants to create a billboard that displays an enlarged $1,000,000 bill. The actual size of the bill is 2.61 inches by 6.14 inches. If the billboard is 48 feet wide, what's the scale of the bill to the billboard? A. 1′ = 8.71″ B. 1′ = 7.81″ C. 1″ = 8.71′ D. 1″ = 7.81′
We know how wide the billboard will be. Therefore, to know how much the original image should be enlarged, you must divide the final width of the billboard between the current width of the invoice.
We know both data, then we perform the operation:
48 feet /6.14 inches = 7.81 feet / inches .
Therefore the correct answer is option D. 1″ = 7.81′
For the bill to cover the billboard, the bill must be expanded by a factor of 7.81 feet long per inch long that has the original image.

The square below has an area of 4 - 4x + x^2 square meters.
What expression represents the length of one side of the square?
Side length = ___ meters
Answer:
(2-x) or (x-2)
Step-by-step explanation:
Given that area of a square is 4-4x+x^2
We know that area of a square = side x side = side ^2
Hence side of a square = square root of area
To find side let us take square root of 4-4x+x^2
This can be written as 4-4x+x^2 = 2^2 -2(2)(x)+x^2
Recall the identity a^2-2ab+b^2 = (a-b)^2
Here a = 2 and b = x
Hence square root can be either 2-x if x<2 or x-2 if x>2
Answer is 2-x or x-2
A farmer has 113 sheep. 47 of them are males. How many more female sheep are there than make sheep?
113-47 = 66 female sheep
66-47 = 19
19 more female sheep than male sheep
The total number of sheep the farmer has is 113 sheep. Since 47 of them are males and you are solving for the number of female sheep, you can subtract 47 sheep from 113 sheep.
113 - 47 = 66
We have figured out that there are 113 total sheep, 47 male sheep, and 66 female sheep. The question is asking for how many more female sheep are there than male sheep, so subtract the number of male sheep from the number of female sheep.
female sheep - male sheep = answer
66 - 47 = 19
There are 19 more female sheep than there are male sheep.
FOR THE LOVE OF GOD HELP ME PLEASE!!The trinomial x2 – 3x – 4 is represented by the model.
What are the factors of the trinomial?
( x + 1) and (x - 4)
to factor the trinomial consider the factors of the constant term ( - 4) which sum to give the coefficient of the x-term ( - 3 )
these are - 4 and + 1
x² - 3x - 4 = (x - 4)( x + 1)
which of the following are solutions to the quadratic equation? x^2 + 8x + 16 =7
E and F
note that x² + 8x + 16 is a perfect square which factors as ( x + 4 )², thus
(x + 4 )² = 7 ( take the square root of both sides )
x + 4 = ± √7 ( note plus or minus )
subtract 4 from both sides )
x = ± √7 - 4
x = √7 - 4 → E
x = - √7 - 4 → F
Answer:
E & F

The length of a rectangle is 3 inches more than its width if the perimeter is 42 in find the dimensions of the rectangle
The problem uses the perimeter formula. P = 2w + 2l where w is the width, and l is the length.
We know the length (l) is 3 inches longer than it's width (or l = w+3). Substitute w +3 into Perimeter equation.
P = 2w + 2(w+3). That simplifies to P = 4w + 6.
Since P + 42, we have 42 = 4w +6.
With some simple algebra we find that w = 9 and l = 12.

Select an equivalent form of this equation: x/12 - 7 = x/4
To solve the equation x/12 - 7 = x/4, multiply all terms by 12 to eliminate the fractions. Simplify the equation and solve for x by isolating the variable.
Explanation:To solve for x, we need to find an equivalent form of the given equation. First, let's get rid of the fractions by multiplying all terms by 12 (the common denominator).
After multiplying, we get 12(x/12) - 12(7) = 12(x/4), which simplifies to x - 84 = 3x.
Next, subtract x from both sides of the equation to isolate the variable. This gives us -84 = 2x.
Finally, divide both sides of the equation by 2 to solve for x. The equation becomes -42 = x. Therefore, an equivalent form of the given equation is x = -42.

The inequality 5m − 7 > 16 holds true for all numbers (Less? or Greater?) than (3? or 4?) in the set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.
Final answer:
The inequality 5m - 7 > 16 is true for all numbers greater than 4 in the set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. After isolating m in the inequality, we find that m must be greater than 4.6. Since we're dealing with whole numbers, the inequality holds for numbers greater than 4.
Explanation:
To solve the inequality 5m − 7 > 16, we first isolate the variable m:
Add 7 to both sides of the inequality to get: 5m > 23.
Next, divide both sides by 5 to find the value of m: m > [tex]\frac{23}{5}[/tex], which simplifies to m > 4.6.
Since m must be greater than 4.6, and we are given a set of whole numbers, we are looking for all numbers greater than 4 in the set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. This means the inequality holds true for all numbers greater than 4 in the set.
