A bag contains 11 counters five of the count as a white account is taken out of the bag at random and not replaced a second counter is taken out of the bag at random calculate the probability that only one of the counters is white
The probability that only one of the counter is white is 6/11.
So we know that there are 11 counters, 5 of them are white, 6 are not white.
Let's assume that first we take the white one, the probability is equal to the quotient between the number of white counters and the total number of counters, so we have:
p = 5/11
Now for the second one, we don't want to take a white one, so here the probability is equal to the quotient between the number of non-white counters (6) and the total number of counters (now there are 10, because we took one)
q = 6/10
The joint probability is the product of the individual probabilities, this is:
P = p*q
And, also notice that there are 2 permutations:
first white, then non-white.first non-white, then white.So we need to add a factor 2.
P = 2*p*q = 2*(5/11)*(6/10) = 6/11
The probability is 6/11

OK PLEASE I NEED HELP NOW IM RUNNING OUT OF POINTS :(
The magnitude of the sum of these two vectors is approximately 11.791 units.
How to find the magnitude of the sum of two vectors
In this question we have the representations of two vectors on a Cartesian plane, of which we must find the magnitude of the two vectors. There are different methods to find it, we decide to use a vectorial method. First, sum the two vectors:
R(x, y) = A(x, y) + B(x, y)
R(x, y) = 7.70 · (cos 27.8°, sin 27.8°) + 16.3 · (- sin 20°, - cos 20°)
R(x, y) = (6.811, 3.591) + (- 5.574, - 15.317)
R(x, y) = (1.237, - 11.726)
Second, use the Pythagorean theorem:
R = √[1.237² + (- 11.726)²]
R ≈ 11.791
The magnitude of the sum of these two vectors is approximately 11.791 meters.

Greg is driving his motorhome. It uses 3 gallons of gas for every 21 miles he travels. Complete the table below showing the number of gallons used and the distance traveled
Answer:
I think the answer is 234 miles and 78 gallons.
Step-by-step explanation:
Hope this helped :)
Answer:
You didn't show the problem so ill just make it to where you can answer yourself
Step-by-step explanation:
so if he uses 3 gallons per 21 miles just divide 3 by 21(yes 3 by 21)
So 0.142 is used per mile
So because you don't show how many miles he traveled just take the number of miles he traveled and times it by 0.142
Example: 42 x 0.142 = 5.964 which when rounded is 6
p(x)=x^3-4x^2-8x please help me solve
Answer: The value of p(x) = (-2,6) or p(x) = (-2,0)
Step-by-step explanation:
Given that,
p(x) = x^3-4x^2-8x
p(x) = [tex]x^{3}[/tex] - [tex]4x^{2}[/tex] - 8x
and replace with '0'.
x^3-4x^2-8x = 0
Now, factorizing equation is,
(x+2) ([tex]x^{2}[/tex] - 6x) = 0
(x+2) = 0
x= -2
Therefore, x = -2
and,
([tex]x^{2}[/tex] -6x) = 0
([tex]x^{2}[/tex] -6x+0) = 0
using quadratic formula = - [b ± √[tex]b^{2}[/tex]-4ac] / 2a
substitute the values,
a = 1, b = -6 , c = 0
p(x) = - [-6 ± √[tex]-6^{2}[/tex]-4.1.0] / 2.1
p(x) = - [-6 ± √36-4.1.0] / 2.1
p(x) = - [-6 ± √36-(0)] / 2.1
p(x) = - [-6 ± √36] / 2.1
p(x) = - [-6 ± 6] / 2
p(x) = [6 ± 6] / 2
p(x) = 3 ± 3
Therefore, p(x) = 3+3 = 6
p(x) = 3-3 = 0
So, that we can say the value of p(x) = (-2,6) or p(x) = (-2,0).

The measure of each of the
congruent angles of an isosceles
triangle is 9 less than 4 times the
vertex angle. Find the measures of all
the angles in the triangle.
Answer:
22°, 79° and 79°
Step-by-step explanation:
Let x be the vertex angle and y each of the congruent angles.
The sum of all angles =180°
So x + y + y = 180
x + 2y = 180 ·········· Equation (1)
Given "The measure of each of the congruent angles of an isosceles triangle is 9 less than 4 times the vertex angle", the equation is
y = 4x - 9
Substitute for y in terms of x in equation 1
⇒ x + 2(4x - 9) = 180
⇒ x + 8x - 18 = 180
⇒ 9x - 18 = 180
⇒ 9x = 180 + 18
⇒ 9x = 198
⇒ x = 198/9 = 22
So vertex angle is 22°
Substituting for x in Equation 1:
22 + 2y = 180
2y = 180 - 22
2y = 158
y = 158/2
y = 79°
So each congruent angle is 79°

Using proportions and the percentage concept, it is found that:
25% of Johnny's apples are the Jonagold variety.75% of Johnny's apples are not of the Jonagold variety.63 apples are not of the Jonagold variety.What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, that can be either direct(cross multiplication) or inverse(line multiplication), deriving from proportional relationships. One example of application of proportions is for percentage problems.
This is because a percentage of an amount a divided by a total amount b is given by the following proportion:
P = a/b x 100%.
From the image, we have that 3 out of 12 apples are of the Jonagold variety, hence:
3/12 x 100% = 0.25 x 100% = 25%.
25% of Johnny's apples are the Jonagold variety.75% of Johnny's apples are not of the Jonagold variety.Each apple in the image is equivalent to 7 apples, hence:
