a common multiple of 6 and 8,
What number is a common multiple of 6 and 8?
Answer:
6, 12, 18, 24, 30, 36, etc.
Answer:
24
Step-by-step explanation:
Really any number that has a factor with both 6 and 8 would work, but I'm assuming you need the lowest common multiple, which would be 24.
Solve the system of equations by elimination:
−5x+y+5z=27
5x+5y−4z=−12
−6y−z=−16
Answer:
no asnwer
Step-by-step explanation:
first step:
-5x+y+5z=27
+ 5x+5y-4z=-12
which is
6y+z=15
add -6y-z=-16
which will be 0=-1
this means that there is no answer and that the statement is false.

Hey.. Use a calc dude
PLEASEEE HELP ! I WOULD APPRECIATE IT VERY MUCH :)
hi!
so the original equation is (x^2 -121) / x+ 11.
Those two equations look similar...
well, we know that the top equation looks like a^2 - b^2, and that equation iis equivalent to this equation: (a+b)(a-b).
So if we factor that out, we get:
( (x + 11) * (x-11) )/ (x + 11)
we can cancel the x+11 on the top and the x+11 on the bottom out.
that leaves us with x-11.
Hope this helped!
which point is located at (-5,5)
Answer: Point D is at (-5,2) as the first coordinate is on the "X" axis, and the second coordinate is on the "Y" axis. You would move down the x axis first going 5 to the left, as that would be negative. Then two up as that is positive on the y axis! Hope this Helps!
Step-by-step explanation:
In order to conduct an experiment, 4 subjects are randomly selected from a group of 20 subjects. How many different groups of four subjects are possible?
Answer:
The number of ways to form different groups of four subjects is 4845.
Step-by-step explanation:
In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.
The formula to compute the combinations of k items from n is given by the formula:
[tex]{n\choose k}=\frac{n!}{k!\times (n-k)!}[/tex]
In this case, 4 subjects are randomly selected from a group of 20 subjects.
Compute the number of ways to form different groups of four subjects as follows:
[tex]{n\choose k}=\frac{n!}{k!\times (n-k)!}[/tex]
[tex]{20\choose 4}=\frac{20!}{4!\times (20-4)!}[/tex]
[tex]=\frac{20\times 19\times 18\times 17\times 16!}{4!\times 16!}\\\\=\frac{20\times 19\times 18\times 17}{4\times3\times 2\times 1}\\\\=4845[/tex]
Thus, the number of ways to form different groups of four subjects is 4845.
and are independent Gaussian (Normal) random Variables. has mean 13.9 and variance 5.2; has mean 6.9 and variance 3.8. . (a) Calculate
This question is incomplete, the complete question is;
X and Y are independent Gaussian (Normal) random Variables. X has mean 13.9 and variance 5.2; Y has mean 6.9 and variance 3.8. . (a) Calculate P( W> 10)
Answer:
P( W> 10) is 0.1587
Step-by-step explanation:
Given that;
X ⇒ N( 13.9, 5.2 )
Y ⇒ N( 6.9, 3.8 )
W = X - Y
Therefore
E(W) = E(X) - E(Y)
= 13.9 - 6.9 = 7
Var(W) = Var(X) + Var(Y) -2COV(X.Y)
[ COV(X,Y) = 0 because they are independent]
Var(W) = 5.2 + 3.8 + 0
= 9
Therefore
W ⇒ N( 7, 9 )
so
P( W > 10 )
= 1 - P( W ≤ 10 )
= 1 - P( W-7 /3 ≤ 10-7 /3 )
= 1 - P( Z ≤ 1 ) [ Z = W-7 / 3 ⇒ N(0, 1) ]
from Standard normal distribution table, P( Z ≤ 1 ) = 0.8413
so
1 - P( Z ≤ 1 ) = 1 - 0.8413 = 0.1587
Therefore P( W> 10) is 0.1587

4 < x < 9 x is an interger, write down all the possible values of x
Answer:
The possibel values of x is 5, 6, 7, 8.
Step-by-step explanation:
Integer is a positive or negative whole number.
In this case, x must be positive and it have to be greater than 4 but smaller than 9 so the possible values will be 5, 6, 7 and 8.
It says [tex]x[/tex] is greater than [tex]4[/tex] and it is less than [tex]9[/tex]
The first value which is greater than [tex]4[/tex] is [tex]5[/tex] and the value which is less than [tex]9[/tex] is [tex]8[/tex]. So the answer would be all integers from [tex]5[/tex] to [tex]8[/tex] (inclusive)
[tex]5, 6, 7, 8[/tex] would be the answer! :D

HELP!!! I need help with this question. I am very confused.
Answer:
The answer may be 68?
Step-by-step explanation:
Answer:
44°
Step-by-step explanation:
First, m ∠ D=112° and ∠ABC are congruent in a parallelogram and congruent angles have same measure so m ∠ ABC=112° as well
Second, ∠ABC and ∠CBE are supplementary angels so they add up to 180° because adjacent angles that form a line are suplementary, therefore, ∠CBE=180-112=68°
Third, ∠CBE≅∠BCE because the ΔCEB is isosceles since is given CE≅BE and base angles of isosceles triangles are congruent.
Congruent ∠s have same measure so m∠BCE =68° as well
Last sum of angles in a Δ is 180° so from ΔCEB we have
m ∠E = 180-68-68=44°

this equation -r + 6 + 8r - 14
Answer:
7r-8
Step-by-step explanation:
yout are the two common factors in this case they are 8r and -r which is also -1r and put them in an equation and you di the same for +6 and -14
Firstly we will solve -1r +8r
+8r overpowers -1r so we will use the positive sign for this one. 8-1 is 7 and I we use the positive sign from the overpowered number you get 7r
Now we move on to +6-14
this is just simple addition and subtraction
what is 14-6 it is -8
-14 overpower 6 so we use its sign
Lastly we put it all together and get
7r - 6
Solve for t
t - 6 = 18
Answer:
t=24
Step-by-step explanation:
to answer, you need to isolate the variable t:
t-6=18
t= 6+18
t=24

Hello Everyone! Please help me out anything you know helps. The topic is angles.
Answer: y=28 degrees
Step-by-step explanation:
To find angle B, all we have to do is subtract 145 from 180 since they're supplementary angles- so angle B is 35 degreesNow we can find x, by subtracting 14 from 35-> x=21We can create an equation using what we know about B to find y: 35= 63-ySolve the equation to get y=28 degreesIn this problem we used supplementary angles and algebra. We also used congruency.
Which of the following values of x will result in an imaginary number for
√2x+7
x ≤ -4 will result in an imaginary number. (From the graph it's actually 3.5, so if you want to view in REAL number then it's x ≤ -3.5 which will result in imaginary numbers.)
But if you want an integer then It's x ≤ -4
Real Number as it's x ≤ -3.5

What is the standard form of y –7 = – 23 (x + 1)
Answer:
23x+y=-16
Step-by-step explanation:
Two similar figures have a scale factor of 4/3.
If one side of the smaller figure is 12. determine size of the side of the
corresponding side in the larger figure.
9
16
40/3
32/3
Answer:
This is the concept of scale factors; The length of the larger figure will be calculated as follows;
linear scale factor=[length of larger figure]/[length of smaller figure]
plugging the values in the above formula we get:
let the length of the larger figure be x;
thus;
x/12=4/3
multiplying both sides by 12 to solve for x we get:
12*x/12=4/3x12
x=16
thus the length of the larger figure is x=16
Answer:16
Step-by-step explanation:
12 times 4/3 is 4^2 or 16
