Answer:
9x² + 6x -19
Step-by-step explanation:
= 33x³ + 6x - 9 - 33x³ + 9x² -10
= 33x³ - 33x³ + 9x² + 6x -10 -9
= 9x² + 6x -19

Answer:
1/9 i think not sure
Step-by-step explanation:
Answer:
1/9
Step-by-step explanation:
Well the chance of picking 3 one time is 1/3
The chance of picking 3 the second time is 1/3
So at first, we've succeeded with probability 1/3 and failed with probability 2/3
We don't care what happens next if we've failed - we already failed.
So we've reached the "picking the second card with hope in our hearts" 1/3 of the time and we again succeed with 1/3 of a chance, so the total probability of success is 1/3 * 1/3 = 1/9
Think of the options:
3 and 3 - probability 1/3 * 1/3 = 1/9
3 and non-3 - probability 1/3 * 2/3 = 2/9
non-3 and 3 - probability 2/3 * 1/3 = 2/9
non-3 and non-3 - probability 2/3 * 2/3 = 4/9
Note that all the options sum to 1 - as probabilities of all options always should.

What is conditional probability?The likelihood that event A will occur provided that event B has already happened is known as conditional probability. It is written as "the probability of A given B" and is indicated by the symbol P(A|B).
We must employ conditional probability in order to respond to this inquiry. We are aware that there are 75 pupils in the class overall, with 37 boys and 38 girls. We also know that 22 girls and 23 boys both have GPAs above the national average.
A. Boy with above-average grades equals a boy.
This claim is untrue. The likelihood of picking a guy at random from the class is 37/75, or P(boy). The likelihood of picking a kid from the class who has above-average grades at random is 23/75, or P(boy with average grades). The odds of these two events are not equal.
B. Boy with above-average grades equals P with above-average grades
This claim is untrue. The chance of picking a student with above-average grades at random from the class is P(above average grades), which is (23+22)/75 = 45/75. The likelihood of picking a kid from the class who has above-average grades at random is 23/75, or P(above-average grades boy). The odds of these two events are not equal.
P (boy with above-average grades) C (boy with above-average grades)
This assertion is accurate. P(boy over average grades) = 23/75 and P(above average grades) = 45/75, respectively, are already known values. The odds of these two events are not equal.
D. P(boy | grades over average) = P(boy)
This claim is untrue. The conditional probability that a student will have above average grades given that they are a boy is P(above average grades | boy), which is 23/37. The likelihood of picking a guy at random from the class is 37/75, or P(boy). The odds of these two events are not equal.
Therefore, the correct statement is C. P(boy above average grades) ≠ P(above average grades).

How do I put 4/3 on a fraction number line
Answer:
you would put it as four thirds
Step-by-step explanation:
Answer:
Lets break this down.
4/3 can be simplified as 3/3 and 1/3.
3/3 can also be simplified into 1.
That leaves us with a mixed fraction as 1 1/3.
Now that we know our mixed fraction, we must locate this on a number line.
I drew 3 marks on a number line to demonstrate this, along with a indicator showing where 1 1/3 is.
Since 1 1/3 has one whole, we know that 1 1/3 is greater than 3/3.
We locate 1 on the number line, which is directly in the middle.
Now, we have to move one more to the right, since we have a remaining 1/3.
This leaves us where we are on the photo provided.

Answer:
Z = 80 degrees and X = 8 degrees
Step-by-step explanation:
The reason Z = 80 degrees is because a flat line always has a measure of 180 degrees.
I forget the term, but we know that 6x + 52 is equal to 100 due to some angle theorem. (Once again, I do not remember the term.)
We then subtract 52 from 100 to get the equation 6x = 48. Divide them both by 6 and you get X = 8!

What’s is Arccsc .866 problem
Answer:
arccsc refers to "arc cosecant", or the radian measure of the arc on a circle corresponding to a given value of cosecant. Technical note: Since none of the six trig functions sine, cosine, tangent, cosecant, secant, and cotangent are one-to-one, their inverses are not functions.
what is arccsc equal to? The value of the arccsc function of any argument is an angle in radians whose cosecant function equals the given argument, that is, y = csc-1x if and only if x = cosec(y) for - /2 < y < /2 and y. ˗ˏˋ ❤︎ ࿐

n = 1
a1 = 2*(-3)*1`- 1
a1 = -6 - 1

find the area of the triangle
answer in digital format only
Answer:
33
Step-by-step explanation:
Assume that each cell on the grid represents one unit. One can use the formula, ([tex]A=\frac{(base)(hieght)}{2}[/tex]) to find the area of the triangle. One can see that the base of the triangle is, (11), and the height is (6). Substitute in the given values and solve for the area,
[tex]A=\frac{(11)*(6)}{2}[/tex]
[tex]A=\frac{66}{2}[/tex]
[tex]A=33[/tex]
Find the value for x and y if x+(xy)^1/2+y=14 and x^2+xy+y^2=84
Answer:
[tex]xy = 4 [/tex]
Step-by-step explanation:
Taking the first equation , we have ,
[tex]\implies x + (xy)^{\frac{1}{2}} + y = 14 \\\\\implies x + \sqrt{xy}+ y = 14 \\\\\implies x + y = 14 -\sqrt{xy}\\\\\implies (x+y)^2 = (14-\sqrt{xy})^2 \\\\\implies x^2+y^2+2xy = 196 + xy -28\sqrt{xy} \\\\\implies x^2+y^2+xy = 196 - 28\sqrt{xy}[/tex]
Now according to second equation,
[tex]\\\\\implies 84 = x^2+xy+y^2 [/tex]
Plug on this value ,
[tex]\implies 84 = 196 -28\sqrt{xy}\\\\\implies -112 = -28\sqrt{xy}\\\\\implies \sqrt{xy}=\dfrac{112}{28}\\\\\implies \boxed{\boxed{ xy = 16 }}[/tex]
On substituting this value in terms of one variable of the equation you can get the values of x and y .
A positive angle less than 360 that is coterminal with -725 degrees is
The positive angle is less than 360 which is coterminal with -725 degrees is 85 degrees.
What are Coterminal Angles?Coterminal angles are those with the same beginning side and the same terminal sides. These angles are in the typical position, although their values differ. They have the same sides, are in the same quadrant, and their vertices are identical. The endpoint sides coincide at the same angle when the angles are rotated clockwise or anticlockwise.
An angle that is coterminal with -725 degrees is an angle that has the same initial and terminal sides as -725 degrees, but its measure is between 0 and 360 degrees.
To determine a positive angle less than 360 that is coterminal with -725 degrees, we can add or subtract multiples of 360 from -725 degrees until we get an angle within that range.
In this case, -725 degrees - (2 x 360) = -725-720= -1445.
So, the positive angle less than 360 that is coterminal with -725 degrees is -1445 degrees + 360 = 85 degrees.
