Unfortunately, there isn't enough info about m and n.
If either m or n is even, then m*n is even. By extension, k*m*n is always even as well.
This is because even*even = even and even*odd = even.
Some examples:
2*3 = 6
4*8 = 32
So if either m or n (or both) are even, then k*m*n is never odd no matter what you pick for k.
-----------------------------
If both m and n are odd together, then m*n is odd
Example: 3*5 = 15
To ensure that k*m*n is odd, we need to pick odd numbers for k. If k is even, then we fall into the same scenario as the last section.
The odd single digit numbers are {1,3,5,7,9}. We see that there are 5 items in this list. So there are 5 values we can pick for k to have k*m*n be odd. Furthermore, it means there are 5 different odd numbers of the form k*m*n, with k being a single digit number.
Again, this all relies on the assumption that m and n are both odd.
0=(x-8)^2-100 Solve the problem using any type of way.
0 = (x-8)^2 -100
Add 100 to both sides
100 = (x-8)^2
Take the square root of both sides
10 = (x-8)
Remove the parentheses
10 = x-8
Add 8 to both sides
18 = x

One condition for performing a hypothesis test is that the observations are independent. Mark is going to take a sample from a population of 400 students.How many students will Marta have to sample without replacement to treat the observations as independent?
Answer:
40
Step-by-step explanation:
Given :
The number of the observations in the population is N = 400
There is a [tex]10\%[/tex] rule of assuming the independence.
Now, according to the rule, if we sample without replacement then, any sample of sizes less than or equal to [tex]10\%[/tex] of the population is considered independent.
[tex]10\%[/tex] of population = [tex]10\%[/tex] of 400
[tex]$=\frac{10}{100} \times 400$[/tex]
= 40
Any sample of sizes less than or equal to 40 will be independent for the given population if it is sampled without replacement.
So, the answer is 40.
So, Mark have a sample of 40 students without replacement to treat the observations as independent.

Find the value of x in the triangle below.
804
155
55°
o
75
80°
Ο Ο
85
Answer:
75°
Step-by-step explanation:
First, we need to know that the interior angle sum of a triangle is always 180°.
Now, to find the missing angle aside from x, we need to complete the sum 180-155=25, seeing 155° lies on a straight line. Remembering the interior angle sum of a triangle is always 180°, it is thus clear that 25+80+x=180. If we complete this equation, x=75.

Answer:
T = 55 + 6w and $103
Step-by-step explanation:
We have already saved $55, so that is our constant. We gain $6 per week, so that will be our w value
T = 55 + 6w
Solving for T when w = 8 weeks
T = 55 + 6(8)
T= 55 + 48
T = $103
In triangle ABC, AC=13, BC=84, and AB=85. Find the measure of angle C
Given:
In triangle [tex]ABC, AC=13, BC=84, AB=85[/tex].
To find:
The measure of angle C.
Solution:
Law of Cosines:
[tex]\cos C=\dfrac{a^2+b^2-c^2}{2ab}[/tex]
[tex]\cos C=\dfrac{BC^2+AC^2-AB^2}{2(BC)(AC)}[/tex]
Substituting the given values, we get
[tex]\cos C=\dfrac{(84)^2+(13)^2-(85)^2}{2(84)(13)}[/tex]
[tex]\cos C=\dfrac{7056+169-7225}{2184}[/tex]
[tex]\cos C=\dfrac{0}{2184}[/tex]
[tex]\cos C=0[/tex]
Taking cos inverse on both sides, we get
[tex]C=\cos^{-1}(0)[/tex]
[tex]C=90^\circ[/tex]
Therefore, the measure of angle C is 90 degrees.

Answer:
(36,25)
Step-by-step explanation:
We want to find where the two lines intersect
We know the x value is about 1/2 way between 30 and 40 and the y value is close to 25
The closest value is (36,25)
Step-by-step explanation: I GOT YOU
The point at which the prices are the same would be at (36, 25)
I know this to be true because that's when the lines touch each other (intersect) on the graph. After 36 minutes go by the cost is 25 dollars for both lines. Also the sides have names, cost on the left, and time on the bottom. And the lines stand for the store prices over time. In summary, just look at the number on the side and bottom and see where the lines intersect.

- If f ( x ) = x² + 2x - 1 and g ( x ) = 3x - 2 , then verify the following :
1. [tex] \large{ \bf{( \frac{f}{g})(2) = \frac{f(2)}{g(2)} }}[/tex]
- Irrelevant / Random answers will be reported! *
Step-by-step explanation:
Hey there!
Given;
f ( x ) = x² + 2x - 1
g ( x ) = 3x - 2
To verify:
[tex]( \frac{f}{g} )(2) = \frac{f(2)}{g(2)} [/tex]
LHS:
[tex] (\frac{f}{g} )(x) = \frac{ {x}^{2} + 2x - 1}{3x - 2} [/tex]
~ Insert "2" instead of "x".
[tex] (\frac{f}{g} )(2) = \frac{ {2}^{2} + 2 \times 2 - 1 }{3 \times 2 - 2} [/tex]
Simplify it;
[tex] \frac{f}{g} (2) = \frac{4 + 4 - 1}{6 - 2} [/tex]
Therefore; (f/g)(2) = 7/4.
RHS:
[tex] \frac{f(x)}{g(x)} = \frac{ {x}^{2} + 2x - 1}{3x - 2} [/tex]
~Insert "2" instead of"x".
[tex] \frac{f(2)}{g(2)} = \frac{ {2}^{2} + 2 \times 2 - 1 }{3 \times 2 - 2} [/tex]
Simplify it.
[tex] \frac{f(2)}{g(2)} = \frac{4 + 4 - 1}{6 - 2} [/tex]
Therefore, f(2)/g(2) = 7/4.
Since (f/g)(2) = f(2)/g(2) = 7/4.
Proved!
Hope it helps!
Step-by-step explanation:
f(x) = x² + 2x - 1 g(x) = 3x - 2Soo :
[tex] \tt( \frac{f}{g} )(2) = \frac{f(2)}{g(2)} [/tex]
[tex] \tt( \frac{ {x}^{2} + 2x - 1 }{3x - 2} )(2) = \frac{ {2}^{2} + 2(2) - 1 }{3(2) - 2} [/tex]
[tex] \tt( \frac{ {2}^{2} + 2(2) - 1}{3(2) - 2} )= \frac{7}{4} [/tex]
[tex] \boxed{ \tt \frac{7}{4} = \frac{7}{4} }[/tex]
Soo true.

What is the diameter of a sphere with a volume of 2171m ^ 3 to the nearest tenth of a meter?
Answer:
Diameter of sphere = 16.06 meter (Approx.)
Step-by-step explanation:
Given:
Volume of sphere = 2,171 cubic meter
Find:
Diameter of sphere
Computation:
Volume of sphere = [4/3]πr³
2171 = [4/3]πr³
πr³ = [3/4][2171]
πr³ = [6513 / 4]
πr³ = 1628.25
(3.14)r³ = 1628.25
r³ = 1628.28 / 3.14
r³ = 518.55
r = 8.03 meter (Approx.)
Diameter of sphere = 2r
Diameter of sphere = 2(8.03)
Diameter of sphere = 16.06 meter (Approx.)

Answer:
B only
Step-by-step explanation:
well to solve this question we can consider factor theorem which states that if a Polynomial f(x) is divided by a monomial x-a then x-a is a factor of f(x) if and only if f(a)=0
and to figure "a " we can consider the following equation:
[tex] \displaystyle x - a = 0[/tex]
substitute the given value of a:
[tex] \displaystyle x - 2= 0[/tex]
therefore,
[tex] \displaystyle x = 2[/tex]
option-1:plugin the value of x to the function A(x):
[tex] \displaystyle A(2) = {2}^{3} + {2}^{2} + 4[/tex]
simplify which yields:
[tex] \displaystyle A(2) = 16[/tex]
since A(2)≠0 x-2 is not a factor of A(x)
option-2:similarly substitute the value of x to the function B(x) which yields:
[tex] \displaystyle B(2) = {2}^{3} - {2}^{} - 6[/tex]
simplify:
[tex] \displaystyle B(2) =0[/tex]
so, B(2)=0 Hence x-2 is a factor of x³-x-6
option-3:substitute the value of x to the function C(x)
[tex] \displaystyle C(2) = {2}^{4} + 3.{2}^{} - 10[/tex]
simplify:
[tex] \displaystyle C(2) =12[/tex]
as C(2)≠0 x-2 is not a factor of C(x)
option-4:likewise plugin the value of x to the function D(x):
[tex] \displaystyle D(2) = {2}^{4} - 2.{2}^{3} - 2[/tex]
simplify and that yields:
[tex] \displaystyle D(2) = - 2[/tex]
therefore,D(2)≠0 hence,x-2 isn't a factor of D(-2)
[tex]\boxed{\large{\bold{\textbf{\textsf{{\color{blue}{Answer}}}}}}:)}[/tex]
The factor
x-2=0x=2we have find the value of x .
Now,
we have to select all the polynomial which has x-2 As a factor.
According to the question,
option A:-[tex]A(x)=x^3+x^2+4\\\\A(2)=(2)^3+(2)^2+4\\\\=8+4+4\\\\16≠0[/tex]
so it is not a factor.Option B:-[tex]B(x)=x^3-x-6\\\\=B(2)=(2)^2-2-6\\\\0=0[/tex]
so it is a factor Option C:-[tex]C(x)=x^4+3x-10\\\\=C(2)=(2)^4+3(2)-10\\\\=16+6-10\\\\12≠0[/tex]
so it is not a factoroption D:-[tex]D(x)=x^4-2x^3-2\\\\D(2)=(2)^4-2(2)^3-2\\\\=16-16-2\\\\-2≠0[/tex]
so it is not a factortherefore:-The option B is correct.

A dice game involves rolling 2 dice. If you roll a sum of 2, 3, 4, 10, 11, or 12 you win $5. If you roll a 5, 6, 7, 8, or 9 you lose $5. Find the expected value for the game.
Below is a table for the possible outcomes for rolling two dice.
Answer:
From a glance, -1.67 is the answer.
Step-by-step explanation:
You have a higher probability of losing money than gaining it due to the distribution of probability. Aka: there are more chances to lose than win. As a result, you are expected to lose money. Only -1.67 is the only negative option, which means that we dont even need to do real math since there's already only one choice.
The correct answer is option B which is -1.67 is the answer.
What is probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
You have a higher probability of losing money than gaining it due to the distribution of probability.
There are more chances to lose than win. As a result, you are expected to lose money. Only -1.67 is the only negative option, which means that we don't even need to do real math since there's already only one choice.
