Is the expression 42 undefined? If not, find
the quotient.
-7
Answers
Answer:
-6*-7=42 wdym as in undefined
Step-by-step explanation:
Final answer:
The expression 42/-7 is not undefined and the quotient of this operation is -6.
Explanation:
The expression 42/-7 is not undefined because it involves division by -7, which is not zero—the key criterion for an undefined mathematical operation. In this case, when 42 is divided by -7, the result is a well-defined quotient, which is -6. Therefore, performing the division operation demonstrates that the expression indeed possesses a valid answer. This highlights the importance of distinguishing between dividing by zero, which results in an undefined outcome, and dividing by non-zero numbers, where a clear mathematical solution, such as -6 in this case, can be determined.

first, isolate y:
-3y = -2x + 6
y = (2/3)x - 2
This is a linear function in standard form, so we know that the slope (in this case the rate of change of y in respect to x) is 2/3
Write the number in 2 equivalent forms as a fraction, decimal, or percent.
19 over 19
Answers
The number in 2 equivalent forms as a fraction, decimal are 19/19 and 1.0 respectively.
Explain about the fraction and decimal?
There are just two ways to express numbers: fractions and decimals.
- In comparison to decimals, where the whole number component and the fractional part are joined by a decimal point, such as in the case of 0.5, fractions are expressed as p/q, where q≠0.
- Decimals and fractions show the link between parts and wholes.
- Divide its numerator by the denominator to transform a fraction to a decimal.
- The entire number remains to the left of a decimal when we have a mixed number.
The number given as:
19 over 19
It can be written as:
19/19 (equivalent as fraction)
19/19 = 1.0 (equivalent as decimal)
Thus, the number in 2 equivalent forms as a fraction, decimal are 19/19 and 1.0 respectively.

You are a rhombus. A rhombus is a quadrilateral with all sides equal in length but none of its angles are 90 degrees.
A rhombus is a four-sided polygon with all sides of equal length, making it a special type of parallelogram. Unlike a square, its angles are not right angles (90 degrees).
Rhombi have two pairs of opposite sides parallel, and their diagonals bisect each other at right angles. The rhombus's symmetry and equal side lengths create a balanced and diamond-shaped figure. It is a versatile shape found in various applications, from diamond gemstones to kite designs.
Due to its unique properties, a rhombus is commonly used in mathematics, geometry, and design. Its distinct features make it easily recognizable and distinguishable from other quadrilaterals.

it has tin, among other metals, regardless of what other metals it may have, we know that for the first one, 15% is tin, the rest something else, and we also know that the alloy itself, weights 20 lbs.
now, how much is just the weight of the tin metal in it alone? well, is 15% of 20 lbs, or (15/100) * 20, or 3 lbs, so of all those 20 lbs, only 3 lbs or 15% is tin.
for the second alloy, let's say we'll add "x" lbs, we know the second alloy is 10% tin, how much of that weight is tin? well 10% of x, or (10/100) * x, or 0.10x lbs.
now, we're looking for a mixture, say the resulting lbs of mix will be "y" lbs, and we know the mixture will be 12% of tin, how much is 12% of y? (12/100) * y, or 0.12y.
now, regardless of what "x" and "y" is, we know that 20 + x = y, and that 3 + 0.10x = 0.12y, thus

Answer:
4 Square root 2i
Step-by-step explanation:
if you're ed then this the answer I hope this helps
√-2 = √(-1*2) = √-1 * √2 = i√2 Recall square root of -1 = i
√-18 = √(-1*18) = √-1 * √1`8 = i√18 Recall square root of -1 = i
But √18 = √(9*2) = √9 * √2= 3√2
√-18 = i√18= i(3√2) = 3i√2
√-2 + √-18 = i√2 + 3i√2 = (i + 3i)√2 = 4i√2
So the sum is 4i√2, where i = √-1

a. They are all right-handed?
b. None of them is right-handed?
Answers
Answer:
a) 0.5514
b) 0.0058
Step-by-step explanation:
Data provided in the question:
Probability that the the selected person is righthanded, P(R) = 0.82
Therefore,
Probability that the the selected person is not righthanded, P(R') = 1 - 0.82
= 0.18
Now,
a. They are all right-handed
P (They are all right-handed) = P(R) × P(R) × P(R)
= 0.82 × 0.82 × 0.82
= 0.5514
b) None of them is right-handed
P (None of them is right-handed) = P(R') × P(R') × P(R')
= 0.18 × 0.18 × 0.18
= 0.0058
