2x^2 because you do (-4x^2)-x=(-6x^2) and solve for x to get 2x^2.
Answer:
The missing term is -2x²
Step-by-step explanation:
It is given that,
(10x - 4x² ) - (7x + ?) = 3x - 6x²
To find the missing term
Let 'M' be the missing term we can write the above equation,
(10x - 4x² ) - (7x + M) = 3x - 6x²
⇒ 10x - 4x² - 7x + M = 3x - 6x²
⇒ 10x - 7x - 4x² + M = 3x - 6x²
⇒ 3x - 4x² + M = 3x - 6x²
M = -6x² + 4x²
M = -2x²

Answer:
Alternative C is correct;
Yes, there is evidence at the 5% significance level
Step-by-step explanation:
To determine whether a linear relationship does exist between shoe size and height, we shall simply be testing the null hypothesis;
β=0
against the alternative;
β≠0
From the output, the p-value of the coefficient of height is given as 0.042 or equivalently 4.2%
Since the p-value, 4.2% is less than 5% level of significance we reject the null hypothesis that claims no linear relationship exists between the shoe size and height.
The cone shown has a diameter of 16 m and a slant height of 10 m which choice is the closest to the lateral surface area
Answers
Answer: 251 square meters.
Step-by-step explanation:
You need to use the formula for calculate the lateral surface area of a cone:
[tex]LA=3.14rl[/tex]
Being "r" the radius of the cone and "l" the slant height.
Calculate the radius:
[tex]r=\frac{diameter}{2}\\\\r=\frac{16m}{2}\\\\r=8m[/tex]
Now that you know the radius and the slant height of the cone, you need to substitute them into the formula for calculate the lateral surface area of the cone:
[tex]LA=(3.14)(8m)(10m)\\LA=251.2m^2[/tex]
Therefore, the closest choice to the lateral surface area of the cone is: 251 square meters.

A given by no real distribution has a mean of 153.1 and a standard deviation of 18.2 would a value of 187 be considered usual or unusual? why?
Answers
➷ (18.2 x 2) + 153.1 = 189.5 (this is considered the highest value)
153.1 - (18.2 x 2) = 116.7 (this is considered the lowest value
An unusual value would be more than 2 standard deviations away from the mean in a positive or negative direction.
In this case, the value is less than the highest value.
The value of 187 would be considered usual as it is less than 2 standard deviations away from the mean.

The value of 187 from a distribution with a mean of 153.1 and standard deviation of 18.2 can be considered 'usual'. This conclusion is reached by calculating the Z-score and determining that it falls within the usual range of +/-2 standard deviations from the mean.
Explanation:The question provided is one that tackles the subject of statistics, more specifically, the concepts of mean, standard deviation, and the identification of data as being usual or unusual. The distribution in question has a mean of 153.1 and a standard deviation of 18.2. With a value of 187, we need to determine whether it would be considered usual or unusual.
To answer this, we would utilize the concept of Z-score, which measures how many standard deviations an element is from the mean. A Z-score of +/- 2 or more is generally considered unusual. Let's compute:
Z = (X - μ) / σ
Where:
X is the value, 187 in this case μ is the mean, which is 153.1 σ is the standard deviation, which is 18.2
Substitute these into the Z-score formula:
Z = (187 - 153.1) / 18.2 = 1.86
As the Z score is within the range of +/-2, the value 187 is thus interpreted as usual.

Parallel lines are preserved in which of the following types of transformations?
Answers
Parallel lines are preserved in:
Reflections, Translations & Rotations
Parallel lines maintain their geometric property of not intersecting through all three transformations: rotations, reflections, and translations. Therefore, the correct answer is Option B. l, II, and III.
Explanation:In the field of mathematics, particularly in geometry, transformations involve the manipulation of shapes while preserving their essential properties. In the case of parallel lines, their key property is that they do not intersect, regardless of their length.
Out of the transformations listed - rotations, reflections, and translations - parallel lines are preserved in all three. Therefore, your answer is Option B. l, II, and III.
Specifically, a rotation spins the figure around a fixed point, a reflection flips the figure over a line, and a translation slides the figure along a straight line, parallel to the original lines. In all these transformations, the lines remain parallel to each other.

Need to find the sum of 50
Answers
Answer:
4600
Step-by-step explanation:
This is an arithmetic sequence with common difference d between consecutive terms.
d = - 2 - (- 6) = 2 - (- 2) = 6 - 2 = 4
The sum to n terms of an arithmetic sequence is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex][ 2a + (n - 1)d ]
where a is the first term
here a = - 6, d= 4 and n = 50, hence
[tex]S_{50}[/tex] = [tex]\frac{50}{2}[/tex] [ (2 × - 6) + (49 × 4) ]
= 25 ( - 12 + 196 )
= 25 × 184
= 4600

Order the expressions from least value to greatest value.
Answers
-4.8 • 3.2 = -15.36 (negative times a positive is negative)
2 1/4 + (-1 2/5) first find a common denominator, which would be 20
9/4= 45/20
-7/5 = -28/20
since adding a negative is the same as subtracting a positive, you would subtract 45 and 28 which is 17.
17/20 = 1 3/20 (the answer)
turn the fraction into a decimal by dividing the top number by the bottom number, so 17/20 = 0.85
4.92 divided by -3 equals -1.64 (the answer)
-2 3/5 - (-1 2/5)
make them into improper fractions which is -13/5 and -7/5
it stays negative, so the answer is -6/5 or -1.2
so the answer is
-4.8 • 3.2 < 4.2 divided by -3 < -2 3/5 - (-1 2/5) < 2 1/4 + (-1 2/5)
The order of the expressions from least value to the greatest value is Number 1 < Number 3 < Number 4 < Number 2 and this can be determined by using the arithmetic operations.

Find the area of the irregular figure. I've been stuck on this for awhile. Please help and explain how you did it.
Answers
Answer: 368 ft^2
Step-by-step explanation:
Pretend it is a square and multiply both sides (23*20=460). The triangle that is cut out has an area of 92 (23*8/2). We know the height of the triangle is 8 because 20-12. We subtract 460-92 and get our answer. :)
to the risk of sounding redundant, as the previous posting is absolutely correct.
Check the picture below.
we know the circum-inscribing figure is a square, namely a 23x20, so it has an area of 23*20 = 460 ft².
the distance from the bottom up, is 20, however to the tip of the triangle is 12, so the diffference is 20 - 12 = 8, meaning the triangle, in yellow, has a height/altitude of 8 ft, and we know its base is 23 ft.
so if we simply take the whole area of the square, and then subtract the area of the triangle, we're in effect making a whole in the squarish area, and what's leftover is the shaded area.
[tex]\bf \stackrel{\textit{square's area}}{(23\cdot 20)}~~~~-~~~~\stackrel{\textit{triangle's area}}{\cfrac{1}{2}(23)(8)}\implies 460~~-~~92\implies 368~ft^2[/tex]

What fraction is equivalent to 0.4?
Answers
2/5
How? The decimal .4 is out of ten so it’s 4/10 but then you simplify it and get 2/5
Hope this helps and have a blessed day!
Using the place value chart we can see that the decimal 0.4 is four tenths, so we can write 0.4 as the fraction 4 out of 10 or [tex]\frac{4}{10}[/tex]. Notice however that [tex]\frac{4}{10}[/tex] is not in lowest terms so we need to divide both the numerator and denominator by the greatest common factor of 4 and 10 which is 5.
Therefore, 0.4 can be written as the fraction 2/5, which is in lowest terms.

Davinia.
To add 12'11" and 11'3", convert excess inches to feet and add them to the total feet to get a result of 24 feet 2 inches.
To add the lengths 12'11" and 11'3", we first add the inches (11 inches + 3 inches = 14 inches). Since there are 12 inches in a foot, we convert the 14 inches into 1 foot and 2 inches. We then add the feet (12 feet + 11 feet + 1 foot from the inch conversion = 24 feet). Therefore, the total length is 24 feet 2 inches.

Which operation has an inverse relationship with multiplication? A. Addition B. Division C. Squaring D. Subtraction
Answers
Answer:
B. Division
Step-by-step explanation:
inverse - something that is the opposite or reverse of something else.
Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on. Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry.
Division is the operation that has an inverse relationship with multiplication, as they 'undo' each other through the use of reciprocals.
Explanation:The operation that has an inverse relationship with multiplication is division. In mathematics, inverse operations are pairs of operations that 'undo' each other. Just as subtraction is the inverse operation of addition, division is the inverse when it comes to multiplication. When you multiply a number by another number, you can reverse this action by dividing the product by the same number.
To better grasp this concept, let's consider the relationship between multiplication and division with fractions. If we divide by 8, it is equivalent to multiplying by 1/8. Conversely, multiplying by 1/8 is the same as dividing by 8. Therefore, these two operations, multiplication and division, are interconnected through the use of reciprocals.
