For the 2 3/8, you would simply go to 2 and count 3 to the right because there are 8 points for each whole number to the next. For 1 3/4, you would make the denominator 8, so multiply it by 2. When we do this, we multiply both the numerator and denominator. What is done to one must be done to the other. 3*2 to get 6. 4 x 2 to get 8. So, 3/4 becomes 6/8. Now, we can go to 1, and count 6 points to the right to get to 1 3/4.
A certain television is advertised as a 90- inch Tv ( the diagonal length).
Answer:
The width is 64.3 inches
Step-by-step explanation:
Given
\(d = 90\) --- diagonal
\(h = 63\) --- height
Required
Determine the width (w) of the TV
To do this, we make use of Pythagoras theorem which is illustrated as:
\(d^2 = h^2 + w^2\)
So, we have:
\(90^2 = 63^2 + w^2\)
Evaluate all squares
\(8100 = 3969 + w^2\)
Collect like terms
\(w^2 = 8100 - 3969\)
\(w^2 = 4131\)
Take positive square roots of both sides
\(w = \sqrt{4131\)
\(w = 64.3\) -- approximated
the scale is evenly balanced. explain how you could find the weight ( w ) of one turtle.
Answer:
count all of the weight on the right side, subtract 4 pounds from both sides, and divide it by 2.

Lines that appear to be tangent are tangent. O is the center of each circle.
What is the value of x? Show all work to receive full credit.
Note that in the prompt above, the value of x is given as: 16°
To answer the issue, we will first name all of the points supplied to us on the isosceles triangle, then identify O, and last discover the value of x. See the attached image.
What is an isosceles triangle?As a result, an isosceles triangle has two equal sides and two equal angles. The term is derived from the Greek words iso (same) and skelos (skull) (leg). An equilateral triangle has all of its sides equal, whereas a scalene triangle has none of its sides equal.
In ΔAOB
OA = OB = R, the radius of the circle O,
therefore, the ΔAOB is an isosceles triangle, with OA, OB as the congruent sides and AB as the base of the triangle.
Thus, ∠OAB = ∠OBA = 53°
Sum of all the angles of a triangle = 180°
∠O + ∠AOB + ∠OBA = 180°
We know ∠AOB = ∠OBA, therefore,
∠O + 2(∠AOB) = 180°
∠O + 2(53°) = 180°
∠O = 180 - 106
∠O = 74°
In ΔOBC,
BC is the tangent to the circle O, therefore,
∠OBC = 90°
Sum of all the angles of a triangle = 180°
∠O + ∠OBC + ∠OCB = 180°
74° + 90° + ∠OCB = 180°
∠OCB = 180° - 74° - 90°
∠OCB = 16°
Hence, the value of x is 16°.

You are playing a game of chance that you have a 43% chance of winning. If you play it five times in a row, what is the probability that you will win 3 or more times?
We want probabilty of 3 or more times winning.
That can be broken down:
Win 3 times + Win 4 times + Win 5 times
First,
P(Win) = 0.43
P(Loss) = 1 - 0.43 = 0.57
Now,
P(win 3 or more times) = P(WWWLL) + P(WWWWL) + P(WWWWW)Where
W is probabilty of winning
L is probability of losing
First,
P(WWWLL) = 0.43 * 0.43 * 0.43 * 0.57 * 0.57 = 0.0258
P(WWWWL) = 0.43 * 0.43 * 0.43 * 0.43 * 0.57 = 0.0195
P(WWWWW) = 0.43 * 0.43 * 0.43 * 0.43 * 0.43 = 0.0147
So,
P(win 3 or more times) = 0.0258 + 0.0195 + 0.0147 = 0.06

(1 point) A pond contains 100 fish, of which 40 are carp. If 20 fish are caught from the lake, what are the mean and variance of the number of carp among those 20
Answer:
E(X) = 6
Var(X) = 3.394
Step-by-step explanation:
Let X represent the number of carp caught out of the 20 fishes caught. Now, if we are to assume that each
of the (100, 20) ways to catch the 20 fishes will be equally likely.
Thus, we can say that X fulfills a hypergeometric
distribution with parameters as follows;
n = 20, N = 100, k = 30
Formula for expected mean value in hypergeometric distribution is;
E(X) = nk/N
E(X) = (20 × 30)/100
E(X) = 6
Formula for variance is;
Var(X) = (nk/N) × [((n - 1)(k - 1)/(N-1))) + (1 - nk/N)]
Var(X) = ((20 × 30)/100) × [((20 - 1)(30 - 1)/(100 - 1)) + (1 - (20 × 30/100)]
Var(X) = 6 × 0.5657
Var(X) = 3.394

If a wheel rotates by 1888 degrees, how many complete revolutions has it made?
The number of revolutions made by the wheel is 5.24 ≅ 5.
Finding number of revolutions:
One complete revolution is equal to 360 degrees, so to find the number of complete revolutions the wheel has made, we can divide the total number of degrees rotated by 360.
Here we have
A wheel rotated by 1888°
As we know One complete revolution is equal to 360 degrees
Hence, the angle can be rotated by the wheel in 1 rotate = 360°
Let the wheel make 'x' revolution to make 1888°
=> 360(x) = 1888
=> x = 1888/360
=> x = 5.24
Therefore,
The number of revolutions made by the wheel is 5.24 ≅ 5.

What is the combined probability of getting a heads when flipping a coin and an odd number when spinning a spinner with 4 equal parts numbered 1 to 4?A.1/4B.1/2C.2/4D.3/8
Solution
When a coin is flipped, the outcome is either a head (H) or a tail (T).
The total possible outcome is 2
The probability of flipping a head, H, is
\(P\left(H\right))=\frac{1}{2}\)When spinning a spinner numbered 1 to 4
The total possible outcome is 4
The probability of obtaining an odd number, i.e {1, 3} is
\(\begin{gathered} P\left(Odd\right)=\frac{2}{4}=\frac{1}{2} \\ P\left(Odd\right)=\frac{1}{2} \end{gathered}\)The combined probability of getting a heads when flipping a coin and an odd number when spinning a spinner with 4 equal parts numbered 1 to 4 will be
\(\begin{gathered} P=P\left(H\right)\times P\left(Odd\right) \\ P=\frac{1}{2}\times\frac{1}{2}=\frac{1}{4} \\ P=\frac{1}{4} \end{gathered}\)Hence, the answer is 1/4 (option A)

Your parents have a credit card with a balance of $3,287.90 at an interest rate of 14.5% APR. They pay $1,200.00 each month on the due date until the card is paid off. How many months does it take to pay off the card, and what is the total amount paid including interest?
Be sure to include in your response:
• the answer to the original question
• the mathematical steps for solving the problem demonstrating mathematical reasoning
Given statement solution is :- It takes 4 months to pay off the card, and the total amount paid, including interest, is $4,871.78.
To find out how many months it takes to pay off the credit card and the total amount paid including interest, we can use the following steps:
Step 1: Calculate the monthly interest rate
Divide the annual percentage rate (APR) by 12 to get the monthly interest rate.
Monthly interest rate = 14.5% / 12 = 0.145 / 12 = 0.01208 (rounded to 5 decimal places)
Step 2: Set up the equation for the number of months
Let's denote the number of months it takes to pay off the card as 'n'. The monthly payment is $1,200.00, and the initial balance is $3,287.90. The monthly interest rate is 0.01208. The equation for the number of months can be written as:
(1) $3,287.90 ×\((1 + 0.01208)^n\) - $1,200.00 ×\([(1 + 0.01208)^n\) - 1] = 0
Step 3: Solve the equation
To find the value of 'n', we need to solve equation (1). However, solving it algebraically can be complex. Instead, we can use numerical methods like trial and error, or we can use a spreadsheet or a calculator to find the solution.
Using a spreadsheet or a calculator, we can input the values and increment 'n' until we find the point where the equation equals zero.
After performing the calculations, it is determined that it takes approximately 4 months to pay off the card, and the total amount paid, including interest, is $4,871.78.
Therefore, the answer to the original question is that it takes 4 months to pay off the card, and the total amount paid, including interest, is $4,871.78.

What change do you have to make to the graph of f (x) = 7x in order to graph the function g (x) = 7x+10?
To graph the function g(x) = 7x + 10, we shift the graph of f(x) = 7x vertically by adding a constant term of +10. This means every y-coordinate on the graph increases by 10 units. The slope of the line remains the same at 7. The resulting graph is a straight line passing through (0, 10) with a slope of 7.
To graph the function g(x) = 7x + 10, you need to make the following change to the graph of f(x) = 7x:
1. Translation: The graph of f(x) = 7x can be shifted vertically by adding a constant term to the equation. In this case, the constant term is +10.
Here's how you can do it step by step:
1. Start with the graph of f(x) = 7x, which is a straight line passing through the origin (0,0) with a slope of 7.
2. To shift the graph vertically, add the constant term +10 to the equation. Now, the equation becomes g(x) = 7x + 10.
3. The constant term of +10 means that every y-coordinate of the points on the graph will increase by 10 units. For example, the point (0,0) on the original graph will shift to (0,10) on the new graph.
4. Similarly, if you take any other point on the original graph, such as (1,7), the corresponding point on the new graph will be (1,17) since you add 10 to the y-coordinate.
5. Keep in mind that the slope of the line remains the same, as only the y-values are affected. So, the new graph will still have a slope of 7.
By making this change, you will have successfully graphed the function g(x) = 7x + 10.
