The answer to a subtraction problem is called the difference.
Answer: NO
<u>Step-by-step explanation:</u>
Let's define some of the vocabulary words so we can understand what is being asked.
trinomial: 3 terms → each term is separated by a plus or minus sign
Example: 5x² + 3x + 2
monomial: 1 term → no plus or minus sign exists in the term.
Example: 5x²
degree: the largest exponent → it can be in any of the terms.
Example: 5x² has a degree of 2
It is possible that a monomial has an exponent greater than that of a trinomial so the answer is NO!
trinomial: 5x² + 3x + 2 has a degree of 2
monomial: 5x⁴ has a degree of 4

Step-by-step explanation:
Given that Tensile strength tests were performed on two different grades of aluminum spars used in manufacturing the wing of a commercial transport aircraft. From past experience with the spar manufacturing process and the testing procedure, the standard deviations of tensile strengths are assumed to be known.
Group Group One Group Two
Mean 87.600 74.500
SD 1.000 1.500
SEM 0.316 0.433
N 10 12
The mean of Group One minus Group Two equals 13.100
standard error of difference = 0.556
90% confidence interval of this difference:
t = 23.5520
df = 20
Answer:
f^-1 (x) = - 6x-1 / 10 + 9x
Answer:
Number of positive four-digit integers which are multiples of 5 and less than 4,000 = 600
Explanation:
Lowest four digit positive integer = 1000
Highest four digit positive integer less than 4000 = 3999
We know that multiples of 5 end with 0 or 5 in their last digit.
So, lowest four digit positive integer which is a multiple of 5 = 1000
Highest four digit positive integer less than 4000 which is a multiple of 5 = 3995.
So, the numbers goes like,
1000, 1005, 1010 .....................................................3990, 3995
These numbers are in arithmetic progression, so we have first term = 1000 and common difference = 5 and nth term(An) = 3995, we need to find n.
An = a + (n-1)d
3995 = 1000 + (n-1)x 5
(n-1) x 5 = 2995
(n-1) = 599
n = 600
So, number of positive four-digit integers which are multiples of 5 and less than 4,000 = 600
