Answer: 1
Step-by-step explanation:
[tex]\frac{12}{3*4} \\[/tex]
[tex]\frac{12}{12}=1[/tex]
Final answer:
The phrase 'the quotient of 12 and the product of 3 and 4' translates to the algebraic expression 12 ÷ (3 × 4), which simplifies to 1.
Explanation:
To translate the given phrase into an algebraic expression, we need to understand the terms used. The phrase is 'the quotient of 12 and the product of 3 and 4'. A 'quotient' is the result of division, and a 'product' is the result of multiplication. First, let's find the product of 3 and 4, which is 3 × 4. This equals 12. Now, we take the quotient of 12 by that product, which means we divide 12 by 12. So, the algebraic expression is 12 ÷ (3 × 4).
When we simplify this expression, since 3 × 4 equals 12, and 12 divided by 12 is 1, the expression simplifies to 1. Therefore, the simplified algebraic expression for the phrase 'the quotient of 12 and the product of 3 and 4' is 1.

Evaluate 6²-7²+8²-9²+..+998²-999²
Answer:
-499,485.
Step-by-step explanation:
We can transform this to an arithmetic series by working it out in pairs:
6^2 - 7^2 = (6-7)(6+7) = -13
8^2 - 9^2 = (8-9)*8+9) = -17
10^2 - 11^2 = -1 * 21 = -21 and so on
The common difference is -4.
The number of terms in this series is (998 - 6) / 2 + 1
= 992/2 + 1 = 497.
Sum of n terms of an A.S:
= n/2 [2a1 + (n - 1)d
Here a1 = -13, n = 497, d = -4:
Sum = (497/2)[-26 - 4(497-1)]
= 497/2 * -2010
= -499,485.

The following distribution is not a probability distribution because
the probability values are not discrete.
the values of the variable are negative
the probability values are not increasing
the probability values do not add to 1.
Answer:
Choice 2
Step-by-step explanation:
The following distribution is not a probability distribution because the probability values do not add to 1.
If it were a probability distribution, the sum of all the probability values would be equal to 1.
The sum of the probability values is 0.16 + 0.15 + 0.42 + 0.13 + 0.31,
which is equal to 1.17.
Since the sum is greater than 1, it violates the requirement for a probability distribution.
Hence, the probability values do not add to 1.

B. Any two points along the line.
C. The length of the line.
D. The endpoints of the line,
NEED THIS BY TODAY PLZZZZ!!!!! BE SURE OF YOU ANSWER
To calculate the slope of a line we require any two points along the line.
Explanation:
suppose two points are given that is (x1,y1) (x2, y2) . The equation of a line is y-y1=m(x-x1) , where m is referred to as the slope of the line .
To find m,
m= y2-y1/x2-x1 . Hence this way of finding slope is known as point- slope form. Another form is there known as slope- intercept form
y=mx+c.
But to find a slope , minimum amount of information that we require is points along the line.
Final answer:
To calculate the slope of a line, only two points on the line are needed. Slope is computed as the difference in y-coordinates divided by the difference in x-coordinates of these points.
Explanation:
To calculate the slope of a line, the minimum amount of information needed is any two points along the line. The slope is the rate of change between two points on a line and can be calculated using the formula slope (m) = (Y₂ - Y₁) / (X₂ - X₁), where Y₂ and Y₁ are the y-coordinates and X₂ and X₁ are the x-coordinates of the two points. It is not necessary to know the length of the line, the endpoints specifically, or the x and y intercepts separately.
The slope-intercept form of a linear equation, y = mx + b, shows that m is the slope and b is the y-intercept. Here, the y-intercept is simply the point where the line crosses the y-axis, but it is not required for calculating the slope when you have two points on the line.

What is the measure of angle 4?
Answer:
Angle 4 is 144.
Step-by-step explanation:
Applying the definition of vertical angles, the measure of angle 4 is: 144°.
What are Vertical Angles?Vertical angles are a pair of angles that lie directly opposite each other and are equal in measure to each other.
m∠1 + m∠2 = 180° (linear pair)
Substitute
3x + 12x = 180
15x = 180
x = 12
∠4 and ∠2 are vertical angles, therefore:
m∠4 = m∠2 = 12x
Plug in the value of x
m∠4 = 12(12)
m∠4 = 144°
Therefore, applying the definition of vertical angles, the measure of angle 4 is: 144°.

Explain to me the strategy that you use to order a group of numbers that may be written in different forms, for example percentages, decimals, and fractions.
Answer:
Convert fractions, decimals, and percents to the same form to compare the values. Convert Percent to Decimal or Fraction. Convert Decimal to Percent or Fraction. Convert Fraction to Decimal or Percent. Then figure out which is greater or lesser. Use this information to write a set of numbers or quantities in order from least to greatest or from greatest to least.
Step-by-step explanation:
Ordering numbers mean plan of numbers either from little to enormous or from huge to little. At the point when the numbers are orchestrated in an expanding order, it is known as Ascending Order, and when the numbers are organized in a diminishing order, and afterward they are known as Descending Order. For ascending, check the most modest number from the given rundown and spot it first and afterward put the numbers as indicated by the expanding order. For descending check the greatest number from the given rundown and spot it first and afterward put the numbers as per the diminishing order.
A percentage is a part of an entire communicated as a number somewhere in the range of 0 and 100 instead of as a portion. All of something is 100 percent, half of it is 50%, none of something is zero percent.
A decimal is a part written in an extraordinary structure. Rather than composing 1/2, for instance, you can communicate the division as the decimal 0.5, where the zero is during the ones spot and the five is in the tenths spot.
A fraction just discloses to us what number of parts of an entire we have. You can perceive a fraction by the slice that is composed between the two numbers. We have a top number, the numerator, and a base number, the denominator. For instance, 1/2 is a fraction. You can compose it with an inclined slice like we have or you can compose the 1 on the 2 with the slice between the two numbers. The 1 is the numerator, and the 2 is the denominator.
what is the distance between ( 4, 7 ) and ( 2, 2 )
Answer:
it would be [tex]\sqrt{29}[/tex]
Step-by-step explanation:
To calculate the distance between (4, 7) and (2, 2), we use the distance formula, derived from the Pythagorean theorem: d = √[(x₂ - x₁)² + (y₂ - y₁)²]. Substituting our values into the equation gives a final answer of √29 units.
Explanation:
The subject of your question pertains to the calculation of distance between two points in a two-dimensional space, which is a concept in Mathematics. The points given are (4, 7) and (2, 2). To find the distance between these points, we can use the distance formula, derived from the Pythagorean theorem. The formula is d = √[(x₂ - x₁)² + (y₂ - y₁)²].
Here, (x₁,y₁) is (4, 7) and (x₂,y₂) is (2, 2). By substituting these values into the formula, we get
d = √[(2 - 4)² + (2 - 7)²]
= √[(-2)² + (-5)²]
= √[4 + 25]
= √29.
Therefore, the distance between (4, 7) and (2, 2) is √29 units.

Antonia bought a set of dishes, a towel, and a candle at a housewares store. The set of dishes cost $35.10, the towel cost $21.28, and the candle cost $9.53 before any coupons or discounts. She used a $0.50-off coupon on the candle, a $2.75-off coupon on the towel, and the set of dishes was on sale for 10% off the regular price. Which of the following best describes the amounts that Antonia saved? a. she saved the greatest percentage on the set of dishes b. she saved the greatest percentage on the towel c. she saved the greatest percentage on the candle d. she saved the same percentage on the towel and the set of dishes.
Answer:
A
Step-by-step explanation:
Since $2.75 discount is given on towel
$0.5 discount is given on candle
10% discount is given on set of dishes
We will have to calculate the discount for the set of dishes
10% of $35.10
10/100 ×35.10
=35.1
So the discount on the set of dishes is $35.1
When comparing the discount on the three things she bought,it was observed that she gained a lot from the discount given on the set of dishes
So the answer is A
if it takes 20 farmers 36 days to harvest their fruits, how long would it take 30 farmers to harvest the same amount of fruit ?
Answer:
24 days
Step-by-step explanation:
the information we have is:
Farmers Days
20 ⇒ 36
30 ⇒ x
the table describes that 20 farmers harvest the fruits in 36 days, and the x represents the quantity of days that will take 30 farmers to harvest the fruits.
since the amount of farmers and the amount of days are inversely proportional (if we have more farmers they will need less days, and the other way around) we use the inverse rule of three to solve this problem: multiply the quantities at the top of the table (20 and 36) and divide the result by the remaining amount (30).
we get the following:
x = 20 * 36 / 30
x = 720 / 30
x = 24
It will take 24 days for the 30 farmers to harvest the same amount of fruit

Mikiah must choose between a pack of four 6.5-ounce containers of ice cream for $3.77 or a pack of three 8-ounce containers for $3.87. Which is the better buy? Why?
Answer:
a pack of three 8-ounce containers his is a better purchase
Step-by-step explanation:
In this case, what we must do is calculate the price per ounce and the one with the best value is the best purchase:
option 1: a pack of four 6.5-ounce containers of ice cream for $ 3.77
3.77 / (4 * 6.5) = 0.145
option 2: a pack of three 8-ounce containers for $ 3.87
3.87 / (3 * 8) = 0.161
The value of the price per ounce is less in option 1, therefore, this is a better purchase

Step-by-step explanation:The solution is 7

. This problem can be solved using the Pythagorean Theorem leg2 + leg2 = hyp2. 142 - 72=147,
147
Final answer:
The value of x squared is 147, leading to the answer choice C for the value of x in the right triangle.
Explanation:
To find the value of x in a right triangle where the hypotenuse = 14, and the length of the other side = 7, we will use the Pythagorean Theorem.
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
This can be written as c² = a² + b², where c is the length of the hypotenuse and a and b are the lengths of the other two sides.
Using the given values we have: 14² = 7² + x².
Simplifying this, we get 196 = 49 + x2, and then 196 - 49 = x², which leads to 147 = x².
Therefore, x = √147.
After calculating, we find that x = √147, which simplifies to x = 12.124 (rounded to three decimal places).
However, the answer choices seem to require the square of x, in which case the answer would be 147, which is option C.
