Suppose you have $200 with which you can buy shares of stock from two companies:
ABC Hot Chocolate Company and XYZ Lemonade. Each company's stock currently sells for $100 per share. If the temperature next year is lower than average, the stock price for ABC will increase by $20, and the stock price for XYZ will not change.
If the temperature next year is higher than average, the stock price for XYZ will increase by $20, and the stock price for ABC will not change. There is a 50% chance that it will be colder than average next year, and a 25% chance that it will be warmer than average.
If you purchase two shares of ABC stock and no shares of XYZ stock, there is a _____ chance that your gain will be $40. Otherwise, your gain will be _____.
1) 50%, $0
2) 25%, $20
3) 75%, $30
4) 50%, $20
The chances are that your gain will be $40 if you purchase two shares of ABC stock and no shares of XYZ stock, and if it is not $40 the gain is:
1) 50%, $0
2) 25%, $20
3) 75%, $30
4) 50%, $20
So, the option (4) 50%, $20 is the correct option.
The given question is asking what the chances are that your gain will be $40 if you purchase two shares of ABC stock and no shares of XYZ stock, and what the gain will be if it is not $40.
Mathematically, this can be broken down as follows:
There is a 50% chance that the temperature will be lower than average, in which case the stock price for ABC will increase by $20. Thus, the expected gain from investing in ABC is 50% x $20 = $10.
There is a 25% chance that the temperature will be higher than average, in which case the stock price for XYZ will increase by $20. Since you are not investing in XYZ, your expected gain from this is 0.
Therefore, the expected gain from investing in ABC and not investing in XYZ is 50% x $10 + 25% x $0 = $10 + $0 = $10.
Since you are investing in two shares of ABC stock, your expected gain is 2 x $10 = $20. Thus, there is a 50% chance that your gain will be $40, and otherwise your gain will be $20.

Simplify the following expression using rational exponents. Assume all variables are positive.
a3/5⋅a3/4
Answer:
The simplified expression is a^(21/20).
Step-by-step explanation:
To simplify the expression, we can use the rule for multiplying two powers with the same base, which is to add the exponents.
a^(3/5) * a^(3/4) = a^(3/5 + 3/4) = a^(6/5 + 3/4)
We can then simplify the fractional exponent by finding a common denominator for the numerators, which is 20 in this case:
a^(6/5 + 3/4) = a^(6/20 + 15/20) = a^(21/20)
The simplified expression is a^(21/20).
The area of a rectangular red sticker is 33 millimeters.The perimeter is 28 millimeters. what are the dimensions of the sticker?
The dimensions of the sticker are 11 millimeters and 3 millimeters.
What is Area and Perimeter?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Perimeter of a straight sided figures or objects is the total length of it's boundary.
Given is a sticker which is rectangular in shape.
Area of the sticker = 33 millimeters²
Perimeter of the sticker = 28 millimeters
Area of a rectangle = Length × Width
Perimeter of a rectangle = 2(Length + Width)
Let x be the length and y be the width of the rectangle.
x y = 33
2(x + y) = 28 ⇒ 2x + 2y = 28 ⇒ 2y = 28 - 2x ⇒ y = 14 - x
Substituting y = 14 - x in x y = 33,
x(14 - x) = 33
14x - x² = 33
-x² + 14x - 33 = 0
x² - 14x + 33 = 0
Factorizing the quadratic equation,
(x - 11) (x - 3) = 0
x - 11 = 0 or x - 3 = 0
x = 11 or x = 3
If x = 11, then y = 33/11 = 3
If x = 3, y = 33/3 = 11
Hence the dimensions are 11 millimeters and 3 millimeters.

What are trigonometric ratios?
Trigonometric ratios are ratios of the sides of a right triangle that are used to define the relationships between the angles and the sides of the triangle. The three basic trigonometric ratios are sine, cosine, and tangent, which are commonly abbreviated as sin, cos, and tan, respectively.
The expression (sin 3x)(cos x) − (cos 3x)(sin x) is an example of a trigonometric identity known as the "sin of a difference" formula:
sin(A - B) = sin A cos B - cos A sin B
By comparing this formula to the given expression, we can see that:
A = 3x

The equation of the line with slope 3 that goes through the point (2, 5) is y = 3x - 1.
What is the slope-point form of the line?
The point-slope form of the equation of a line is given by:
y - y1 = m(x - x1)
where m is the slope of the line, and (x1, y1) is a point on the line.
Using the given slope of 3 and the point (2, 5), we can substitute into the point-slope form to get:
y - 5 = 3(x - 2)
Expanding the right-hand side:
y - 5 = 3x - 6
Adding 5 to both sides:

The ratio of the number of model cars that Jim owns to the number of model cars Terrence owns is 8 : 6. Terrence owns 36 models cars. How many model cars does Jim own? How will the ratio change if Jim and Terrence each sell ten of their model cars?
As said, 48 model automobiles are driven by Jim at the moment, and the ratio might alter to 19:13.
What does a mathematical ratio mean?An organisation of the integers a and b stated as a/b is still a ratio if b is truly not comparable to 0. Two ratio with the same value are established by the percent formula. As an illustration, you might write your ration as follows: 1:3 when there is 1 man and 3 females.
You know there's an 8:6 ratio between the grand total of model cars Jim and Terrence possess.
As a result, you can respond to the assignment as follows: Assume Jim owns x different car models.
8/6 = x/36
x = 36*8/6
x = 288/6
x = 48
The new percentage of Jim's against Terrence's model vehicles will be as follows because both Jim & Terrence sell ten of their model cars:
(48-10)/(36-10) = 38/26 = 19/13

7. The functions f(x)=2* and g(x)=8(2)* are both shown graphed.
The graph of g is certainly a vertical stretch of the function f by a
factor of 8. But, it is also a shift off by three units left. Can you
explain why this is using an exponent law?
The function g(x) = 8(2)^x is also a shift left by 3 units of f(x) = 2^x, as 8 = 2³, hence 8(2)^x = 2^(x + 3).
What is a translation?A translation happens when either a figure or a function are moved horizontally or vertically.
The four translation rules for functions are given as follows:

f(x) = 2^x.g(x) = 8(2)^x.8 is the third power of 2, hence:
8 = 2³.
When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents, hence:
8(2)^x = 2³ x 2^x = 2^(3 + x) = 2^(x + 3).
As x -> x + 3, a translation left 3 units happened.
