What is the factored form of y^2 + xy − 6x^2?
Answer:
(y-2x)(3x+y)
B
Answer:
[tex]B. \left(y-2x\right)\left(y+3x\right)[/tex]
Step-by-step explanation:
[tex]y^2+xy-6x^2[/tex]
Break the expression into group:
[tex](yx^{2} -2xy)(3xy-6x^{2} )[/tex]
factor out [tex]y[/tex] from [tex]y^{2} -2yx:y\left(y-2x\right)[/tex], and factor out, [tex]3x[/tex] from [tex]3yx-6x^2:3x\left(y-2x\right)[/tex]
[tex]y\left(y-2x\right)+3x\left(y-2x\right)[/tex]
Now, factor out common terms: [tex]y-2x[/tex]
[tex]\left(y-2x\right)\left(y+3x\right)[/tex]

Tomer is playing a game that involves rolling 5 6-sided dice at once, and his goal is to roll the dice so exactly 4 of
them land showing a "1".
Which of the following would find the probability that exactly 4 of the 5 dice land showing a "1"?
A)(1/6)^4(5/6
B)(6/5)(1/6)^4(5/6)
C)(6/5)(1/6)^4(5/6)^2
D)(5/4)(1/6)^4(5/6)
E)(5/4)(1/6)^4(5/6)^2
Answer: D
(5/4) (1/6) 4^ (5/6)
Step-by-step explanation: I’m taking the test for this unit and I got it wrong but this was the CORRECT answer.
The probability that exactly 4 of the 5 dice land showing a "1" if, Tomer is playing a game that involves rolling 5 6-sided dice at once is 5 / 4 × (1 / 6)⁴ × (5 / 6), so option D is correct.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a value between 0 and 1.
Given:
Tomer is playing a game that involves rolling 5 6-sided dice at once,
Calculate the probability that exactly 4 of the 5 dice land showing a "1" as shown below,
Probability = 5 / 4 (1 / 6)⁴ × (5 / 6)⁵⁻⁴
Probability = 5 / 4 × (1 / 6)⁴ × (5 / 6)¹
Probability = 5 / 4 × (1 / 6)⁴ × (5 / 6)
Thus, the probability that exactly 4 of the 5 dice land showing a "1" is 5 / 4 × (1 / 6)⁴ × (5 / 6).

What would be the mean if 29
was added to the list?
75, 21, 45, 39, 14
Answer:
37.17
Step-by-step explanation:
Find the mean by adding together all of the numbers, then dividing it by how many numbers there are.
(29 + 75 + 21 + 45 + 39 + 14) / 6
= 37.17
So, if 29 is added, the mean is approximately 37.17

PLEASE HELP IM GONNA FAIL IF I DONT DO GOOD ON THIS MATH TEST PLZ PLZ HELP
Answer:
D
Step-by-step explanation:
Answer: D
The first option is incorrect because 56+angle 3=180 and when you solve it angle 3 equals 124 degrees, not 142 degrees
The second option is incorrect because 56+43+angle 1=180 (because all triangles add up to 180 degrees). When you solve that angle 1 equals 81 degrees, not 99 degrees
The third option is incorrect because angle 1+angle 2=180, and we already know angle 1 equals 81, so when you solve that angle 2 equals 99 degrees, not 137 degrees. So we know the last option is correct.
But if you want to make sure it's correct, you can always solve for angle 4. Angle 4+43=180 degrees, and when you solve it, angle 4 equals 137 degrees, and we know that option is correct.
Hope this helped you!
Find the error then show the correct way step by step.
Question 4
The error was that in step 2, when distributing -3 into the parentheses, the person did not change the sign of 24 so that it was negative, since a negative number multiplied by a positive number will always make a negative number. Here is the correct way to solve this equation:
[tex]-5x+12-7x=-3(5x+8)\\-12x+12=-3(5x+8)[/tex]
Distrubute -3 into the parentheses
[tex]-12x+12=-15x-24[/tex]
Subtract both sides by 12
[tex]-12x+12-12=-15x-24-12\\-12=-15x-36[/tex]
Add 15x to both sides
[tex]-12+15x=-15x-36+15x\\3x=-36[/tex]
Divide both sides by 3
[tex]\frac{3x}{3} =\frac{-36}{3} \\x=-12[/tex]
Question 5
The error was that 2 was added on both sides in step 5 instead of being subtracted from both sides. Here is the correct way to do it, starting from step 4:
[tex]10=16x+2[/tex]
Subtract both sides by 2
[tex]10-2=16x+2-2\\8=16x[/tex]
Divide both sides by 16
[tex]\frac{8}{16} =\frac{16x}{16} \\\frac{1}{2}=x[/tex]

Kerry takes 80% of the blue counters from the box.
Work out the ratio of the number of red counters to the number of blue counters now in the
box.
Give your ratio in its simplest form.
Answer:
The ratio of red to blue would be 60: 6 which can be simplified to 10:1.
The ratio of red to blue counters would be 60: 6 which can be simplified to 10:1
What is ratio ?Ratio is the comparison of two quantities in terms of same units.
Example : If a & b be two numbers, then the ratio is a/b, where b≠0
What is the required ratio ?Let Blue counters = x
Red counters would be = 3 times of blue counters = 3x
There are a total of 120 counters in a box.
First we have to find, the number of red and the number of blue counters:
3x + x = 120
⇒ 4x = 120
⇒ x = 120/4
⇒ x = 30
There are 30 blue counters.
Red counters = 3×30 = 90
Carl took 1/3 of the red, 90 / 3 = 30, so there were 60 red counters left in the box.
Kerry took 80% of the blue, 30 * 0.80 = 24, so there were 6 blue counters left in the box.
The ratio of red to blue counters would be 60: 6 which can be simplified to 10:1.

The solution is, the area of the following figure is 360 in^2.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
For this case we have that by definition, the area of a rectangle is given by:
A = l*w
In this case, the rectangle is 18 in side, & 21 in.
then:
A = 18*21
= 378
On the other hand, the area of a triangle is given by:
A = 1/2 b * h
Where:
b: It is the base of the triangle
h: It is the height
We have according to the figure that:
b = 21 - 17 = 4
h = 18 - 9 = 9
So:
A = 1/2 *4 *9
=18
Finally, the area of the figure is:
378 - 18
=360
Answer: The solution is, the area of the following figure is 360 in^2.
