The probability of selecting a black pair of socks first, then a blue or white pair of socks is 27/136.
The probability of selecting a black pair of socks first is:
probability = (number of black pairs)/(total number of pairs)
= 8/17
Once a black pair of socks has been selected, there are 16 pairs of socks left in the drawer. Of these 16 pairs, 9 are either blue or white.
The probability of selecting a blue or white pair of socks second is:
probability = (number of blue and white pairs)/(number of remaining pairs)
= 9/16
Therefore, the overall probability of selecting a black pair of socks first, then a blue or white pair of socks is:
probability = (8/17)*(9/16)
= 27/136

Which graph represents points on the polar curve r = 2 + 5sin(θ)?
Answer:
Graph 2
Step-by-step explanation:
See image attached. Hope this helps.
The second graph shown the polar curve at r = 7.
Given ,
Equation of polar curve = r = 2 + 5sin(θ)
We have to find ,
Which of following graph show polar curve ,
At r = 2 + 5sin(θ)
The area between two curves in the polar coordinate system, first find the points of intersection, then subtract the corresponding areas.
First graph ; r = 2 + 5sin(θ)
Where ,
[tex]\theta = 0[/tex]
r = 2 + 5sin0
r = 2 + 5 (0)
r = 2
Second graph : r = 2 + 5sin(θ)
Where
[tex]\theta = \frac{\pi }{2}[/tex]
Then,
r = 2 + sin[tex]\frac{\pi }{2}[/tex]
r = 2 +5 ( 1 )
r = 2+5
r = 7
Third graph ; r = 2 + 5sin(θ)
where
[tex]\theta = \pi[/tex]
Then,
r = 2 + 5sin[tex]\pi[/tex]
r = 2 + 5(0)
r = 2
Fourth graph ; r = 2 + 5sin(θ)
Where
r = 2 + 5sin[tex]\frac{3\pi }{2}[/tex]
r = 2 + 5 (-1)
r = -3
Fifth graph ; r = 2 + 5sin(θ)
Where
[tex]\theta = 2\pi[/tex]
r = 2 + 5sin(2π)
r = 2+ 5 (0)
r = 2
Comparing all the value of the graph ,the second graph shown the polar curve at r = 7.
Hence, The second graph shown the polar curve at r = 7.

Step-by-step explanation:
angle A + angle B + angle C = 180° [Sum of all angles of a triangle is 180°]
=> 2x+1 + x+15 + x = 180°
=> 4x + 16 = 180°
=> 4x = 180° - 16°
=> 4x = 164°

Imagine that James has been bowling for over 10 years and never gets any better or any worse. The probability that he will bowl a strike on any attempt of rolling a bowling ball stays at a constant 55%. During a particular bowling game, what is the probability that James will not bowl a strike until his fourth attempt?
Answer:
5.01%
Step-by-step explanation:
In order to calculate a sequence of events you need to multiply the probability of each event happening with one another in decimal form. In this scenario, the probability of James bowling a strike is 55% meaning that the probability of James NOT bowling a strike is 45%. We want to know the probability of James NOT bowling a strike for 3 attempts and then bowling a strike on his fourth attempt. We first turn these probabilities into decimal form by dividing them by 100. And then multiply...
55 / 100 = 0.55
45 / 100 = 0.45
0.45 * 0.45 * 0.45 * 0.55 = 0.05011875
Multiply by 100 to get percentage.
0.05011875 * 100 = 5.01%
Fomular for finding perimeter area and circumference of a circle
Answer:
perimeter of a circle=2πR
The perimeter of a circle is the circumference of the circle.
CIRCUMFERENCE
There are two formulas:
1. C = πd (use if the problem gives you the diameter only)
2. C = 2πr (use if the problem gives you the radius only)
AREA
There are several area formulas for a circle but I think for you at your level of math, A = πr^2 is all you need to know.

What is random selection ?A selection that is chosen randomly (purely by chance, with no predictability). Every member of the population being studied should have an equal chance of being selected.
According to the question
The supervisor at an office randomly selected 45 employees and observed their work habits.
She recorded
i > number of items sold
ii > total time the employees spent at their desk
As per observation
Number of items sold = discrete
as it is not possible to sell items in a continuous manner
But
time spent at desk = continuous
as every employee spend time at there desk
Hence, the random variables from the survey is number of items sold, discrete; time spent at desk, continuous

Find the area of the Compound shape
The answer is 45 m^2
I just need the steps....
Answer:
45 cm^2
Step-by-step explanation:
Dividing the shape into the two separate components of a square and a triangle makes it easier.
The square area is found by multiplying the side by the side, 6cm*6cm which gives us 36cm^2.
Then the triangle the height is 3cm and the base is 6cm. Using the formula 1/2*base*height.
Which would be 1/2*6*3=9cm^2.
Adding the two, 9+36= 45cm^2.

If 4.6 plus 1.9 times a number equals the sum of the number and 94.6, what is the number? Express your answer as a simplified fraction or a decimal rounded to two places.
Answer:
The number is:
x=99.67Step-by-step explanation:
Let 'x' be the number
4.6 plus 1.9 times a number 'x' = 4.6 + 1.9xSum of number 'x' and 94.6 = x+94.6Given that 4.6 plus 1.9 times a number equals the sum of the number and 94.6.
so the equation becomes
[tex]4.9+1.9x=x+94.6[/tex]
[tex]1.9x-x=94.6-4.9[/tex]
[tex]0.9x=89.7[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:}10[/tex]
[tex]0.9x\cdot \:10=89.7\cdot \:10[/tex]
[tex]9x=897[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}9[/tex]
[tex]\frac{9x}{9}=\frac{897}{9}[/tex]
[tex]x=\frac{299}{3}[/tex]
[tex]x=99.67[/tex]
Therefore, the number is:

1. Zero point six.
2. In 0.6 the 6 is in tenths place, so place 6 over 10 to create the equivalent fraction 6/10, and 0.60 is 60/100.
3. We can use the same diagram to represent 0.6 and 0.60 because they are equivalent, 0.6 is 60 percent cause the 6 is in the tenths place, 0.60 is also 60 percenr take the zero away and keep the decimal point which is .60 the 6 is still in tenths place.
