Answer:

5/6 and 1/4

Step-by-step explanation:

In order to add and subtract fractions, you have to first find a common denominator for both fractions. So, for your first question 1/3 + 1/2, your common denominator would be 6 because it is the least common multiple. So, multiply the top and bottom of 1/3 by 2 to get 2/6 and multiply the top and bottom of 1/2 by 3 in order to get 3/6. Next add your products together 2/6 + 3/6 but only add the numerator, not the denominator. Finally you get, 2/6 + 3/6 = 5/6.

For your second equation, you basically do the same thing, but for the last part, you subtract instead. First, find the least common multiple (common denominator) for 2 and 4, which is 4. Since, 3/4 already has a denominator of 4, you don't have to change that fraction at all, just change 1/2. Next multiply the top and the bottom of 1/2 by 2 to get 2/4. Finally, subtract 3/4 - 2/4 = 1/4.

Answer:

1. 5/6

2. 1/4

Step-by-step explanation:

1. 1/3 + 1/2

Step 1. Find a common denominator for both fractions (by taking the denominator and finding their least common multiple)

Answer:

3: 3, 6, 9, 12, 15,…

2: 2, 4, 6, 8, 10,…

The least common multiple will be 6

So the new denominator for both fractions is 6

Step 2. Rewrite the fractions using the same denominator

Answer:

1/3 = ?/6 1/2 = ?/6

1/3 = 2/6 1/2 = 3/6

(To get the numerator of the fraction, note that to get the denominator by a number being multiplied by that number, that same number as to be multiplied to the numerator)

Step 3. Add (2/6 + 3/6)

Answer:

2/6 + 3/6 = 5/6

(Denominator stays the same when subtracting or adding)

——————————————————-

2. 3/4 - 1/2

Step 1. Find a common denominator for both fractions (by taking the denominator and finding their least common multiple)

Answer:

2: 2, 4, 6, 8, 10,…

4: 4, 8, 12, 16, 20,…

The least common multiple will be 4

So the new denominator for both fractions is 4

Step 2. Rewrite the fractions using the same denominator

Answer:

3/4 = ?/4 1/2 = ?/4

3/4 = 3/4 1/2 = 2/4

(To get the numerator of the fraction, note that to get the denominator by a number being multiplied by that number, that same number as to be multiplied to the numerator)

Step 3. Subtract (3/4 - 2/4)

Answer:

3/4 - 2/4 = 1/4

(Denominator stays the same when subtracting or adding)

The statement is incorrect because a confidence interval provides a range where we are 90% confident that the population mean falls, not where 90% of the data lies.

The statement made by the classmate is incorrect.

A 90% confidence interval does not represent the range in which 90% of the data falls. Instead, it provides a range of values within which we can be 90% confident that the true population parameter lies. In this case, the interval is given as 22.5 < u < 32.0, where "u" represents the population mean.

To clarify, a 90% confidence interval implies that if we were to take multiple samples from the population and calculate the confidence interval for each sample, approximately 90% of those intervals would contain the true population mean.

It is important to understand that a confidence interval does not describe the distribution or range of the actual data points themselves. It is solely an estimate of where the population parameter (in this case, the mean) is likely to lie with a specified level of confidence.

If each of X, Y, and N are positive integers, then the value of X+Y+N is 212.1

A collection of inequalities for which we consider common solution for all inequalities is called a system of inequalities.

WE are given that A red purse contains $7, and a black purse contains $10. Each package contains X red purses and Y black purses.

X = 7

Y = 10

If there are N packages (N ≥ 2) and the total value of them is $2021

X + Y = One packages

N packages = N(X + Y ) = 10 N

if each of X, Y, and N are positive integers, then;

10 N = 2021

N = 2021/10

N = 202.1

The statement d. -5 + (-6) = -11 is true, and can be expressed mathematically as -5 + (-6) = -11 and calculated by starting with -5 and adding -6, which results in a larger negative number, -11.

The addition statement shown is d. -5 + (-6) = -11. This statement can be expressed in a mathematical formula as -5 + (-6) = -11. The calculation for the statement can be performed by starting with -5 and adding -6 to it. When adding two negative numbers, the sum is a larger negative number. Therefore, the calculation for -5 + (-6) is -11.

To understand this further, we can use the number line. Starting at -5, if we move 6 units to the left, we reach -11. This is because each unit represents a negative number. Therefore, 6 units to the left of -5 is -11. This illustrates that -5 + (-6) = -11.

In conclusion, the addition statement shown is d. -5 + (-6) = -11. This can be expressed in a mathematical formula as -5 + (-6) = -11 and the calculation can be performed by starting with -5 and adding -6 to it, resulting in a larger negative number, -11.

For each pound of the blend, Cold Beans should use 3 pounds of Guatemalan coffee.

This means that in a 6-pound bag of the blend, they would use \(3 \times 6 = 18\)pounds of Guatemalan coffee.

Let's assume that x pounds of Guatemalan coffee are used per pound of the blend.

Given information:

Cost of Guatemalan coffee = $11/lb

Cost of the other coffee = $5/lb

Desired cost of the blend = $8/lb

Total weight of the blend = 6 pounds

To find the ratio of Guatemalan coffee to the total blend, we can set up the equation:

\((x \times 11 + (6 - x) \times 5) / 6 = 8\)

In this equation, \((x \times 11)\) represents the cost of the Guatemalan coffee in the blend, and\(((6 - x) \times 5)\) represents the cost of the other coffee in the blend.

The numerator is the total cost of the blend, and we divide it by 6 (the total weight of the blend) to find the cost per pound.

Now, let's solve the equation for x:

(11x + 30 - 5x) / 6 = 8

6x + 30 = 48

6x = 48 - 30

6x = 18

x = 18/6

x = 3

Therefore, for each pound of the blend, Cold Beans should use 3 pounds of Guatemalan coffee.

This means that in a 6-pound bag of the blend, they would use \(3 \times 6 = 18\)pounds of Guatemalan coffee.

To summarize, to achieve a cost of $8 per pound for a 6-pound bag of blend, Cold Beans should use 3 pounds of Guatemalan coffee per pound of the blend.

The sum of the perimeters of the squares formed through geometric sequence is; 80 + 40√2.

We want to find the sum of the perimeters of the squares formed;

From the diagram attached, we see that;

In ∆PCQ;

<PCQ = 90°,

Then PQ² = PC² + QC²

Since, P and Q are mid - points of square ABCD, then it means that;

PC = BP = 5

QC = DQ = 5

Thus , PQ = √(25 + 25) =

PQ = √50 = 5√2

Since; E,F,G and H are mid-points of square PQRS, then it means that;

EP = PF = (5√2)/2

FQ = QG = (5√2)/2

Now , In ∆ FQG

∠FQG = 90°

Then ,FG²= FQ²+GQ²

FG² = 5

Similarly , The process the continued indefinitely .

Sum of the perimeters of the squares formed = perimeter of square ABCD+ Perimeter of square PQRS + Perimeter of square PQRS+....+∞

= (4 × 10) + (4 × 5√2) + (4 × 5) +......+∞

= 40 + 20√2 + 20 + ...... + ∞

In this Infinite geometric series, we see that;

A quadratic equation is a polynomial equation whose highest degree is two.

If we substitute \(a=0\) into the standard form of a quadratic equation \(y=ax^2+bx+c\) then we eliminate the variable with degree 2.  This means it is no longer a quadratic equation and has become a linear equation, since a linear equation is an equation in which the highest degree is one.

To determine the key features of the function g(x), we make use of the first

g(x) = (x + 2)(x − 1)(x − 2)

So, we have

This is when the function equals 0

(x + 2)(x − 1)(x − 2) = 0

Evaluate

x = -2, 1 and 2

15/7 : 15/10a = 5/14 : 8/10 Step 1: Make everything a fraction or decimal

15/7 X 8/10 = 15/10a X 5/14 Step 2: 1st of first fraction or decimal X last of the other, and the last of the 1st X 1st of the other

3/7 X 4/1 = 15/2a X 1/14 Step 3: Simplify

12/7 = 15/28a OR 15/28a = 12/7 Step 4: Multiply both sides so that there is one fraction on each side

15/28a X 28/15 = 12/7 X 28/15 Step 5: Multiply both sides by the reciprocal of the variable fraction; in this case, the reciprocal of 15/28: 28/15

And then, Step 5: Get the answer

In Mathematics and Geometry, the translation of a graph to the left simply means a digit would be subtracted from the numerical value on the x-coordinate of the pre-image:

g(x) = f(x - N)

Conversely, the translation of a graph upward means a digit would be added to the numerical value on the y-coordinate (y-axis) of the pre-image.

g(x) = f(x) + N

Note: "Point A is one unit left and two units up from the origin. "

Since point A is one unit left and two units up from the origin (0, 0), we can logically deduce the following:
