Part A
2 white, 5 red, 7 total
P(1st white) = 2/7
P(1st white, 2nd white) = P(1st white)*P(2nd white)
P(1st white, 2nd white) = (2/7)*(4/9)
P(1st white, 2nd white) = 8/63
Let m = 8/63
---------------
P(1st red) = 5/7
P(1st red, 2nd red) = P(1st red)*P(2nd red)
P(1st red, 2nd red) = (5/7)*(7/9)
P(1st red, 2nd red) = 5/9
Let n = 5/9 = 35/63
---------------
m+n = P(both are same color)
m+n = 8/63+35/63
m+n = 43/63
Answer: 43/63========================================
Part B
m = P(first white then red)
m = (2/7)*(5/9)
m = 10/63
n = P(first red then white)
n = (5/7)*(2/9)
n = 10/63
r = P(second bead isn't same color as first)
r = m+n
r = 10/63+10/63
r = 20/63
Answer: 20/63========================================
Part C
m = P(1st white, 2nd white)
m = (2/7)*(4/9)
m = 8/63
n = P(1st red, 2nd white)
m = (5/7)*(2/9)
m = 10/63
m+n = P(2nd is white)
m+n = 8/63+10/63
m+n = 18/63
m+n = 2/7
Answer: 2/7========================================
Part D
If we withdraw 1 white bead, but we add it back in, then the probability of selecting white has not changed on the second selection.
The same can be said if we picked a red bead as well. This is because we simply replace the red bead with a copy of some other red bead.
Nick's statement is another way of saying replacement is happening.

It is estimated that the distance traveled by each volunteer driver at the Huntington VA Medical Center is normally distributed with a mean of 50 thousand miles and a standard deviation of 12 thousand miles each year. What percentage of drivers can be expected to travel either below 30 or above 60 thousand miles in a year?
Answer: 25.08%
Step-by-step explanation:
Given: Distance traveled by each volunteer driver is normally distributed.
Mean ([tex]\mu[/tex]) = 50 thousand miles
standard deviation ([tex]\sigma[/tex])= 12 thousand miles
Let X = distance traveled by each volunteer driver
Required probability : [tex]P(X<30)+P(X>60)[/tex]
[tex]=P(\dfrac{X-\mu}{\sigma}<\dfrac{30-50}{12})+P(\dfrac{X-\mu}{\sigma}>\dfrac{60-50}{12})\\\\=P(z<-1.67)+P(z>0.83)\ \ \ [z=\dfrac{X-\mu}{\sigma}]\\\\= (1-P(z<1.67))+(1-P(z<0.83)\ \ \ [P(Z<-z)=1-P(Z<z)=P(Z>z)]\\\\= 2- P(z<1.67)-P(z<0.83)\\\\= 2- 0.9525-0.7967=0.2508\ \ [\text{By p-value table}][/tex]
Hence, percentage of drivers can be expected to travel either below 30 or above 60 thousand miles in a year = 25.08%

The cost of 6 1/2 kg of apples is Rs. 520. What is the rate of one kg of apples
Step-by-step explanation:
So, cost of 6.5 kg of apples is Rs. 520 and we need to find cost of one kg apples.
It can be done just by applying Unitary Method!So,
6.5 kg -- Rs. 520
1 kg -- Rs.(520/6.5) = Rs.80
So, cost of 1 kg apples is Rs.80.Find three consecutive integers such that when three times the third is increased by the first, the result is 8 less than five times the second.
Answer:
9, 10 and 11Step-by-step explanation:
x - the smallest of three consecutive integers (the first)
x+1 - the next of three consecutive integers (the second)
x+2 - the last of three consecutive integers (the third)
3(x+2) - three times the third integer
3(x+2)+x - three times the third increased by the first
5(x+1) - five times the second tnteger
5(x+1)-8 - 8 less than five times the second
3(x + 2) + x = 5(x + 1) - 8
3x + 6 + x = 5x + 5 - 8
4x + 6 = 5x - 3
-4x -4x
6 = x - 3
x = 9
x+1 = 10
x+2 = 11
Check: 3×11+9 = 33+9 = 42, 5×10-8=50-8 = 42

when a figure translated, reflected, or rotated, what’s the same about the original figure and it’s image? what’s different
Answer:
The size of the figure is still the same, but the positioning on the coordinate grid is different.
Step-by-step explanation:
The size of a figure remains constant when it is translated, reflected, or rotated, but its location on the coordinate grid changes.
What is reflection?A reflection is a type of transformation that involves flipping a shape, known as the preimage, across a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you turned the form across the line to graph a reflection. The reflection equation of the new reflected graph will be y=f(x), y = f (x) given an equation, y= -f(x), y = -f (x). In other words, the function is just multiplied by 1, which results in a curve that crosses the x-axis.The size of a figure remains constant when it is translated, reflected, or rotated, but its location on the coordinate grid changes.As, it is stated in the description that the size of a figure remains constant when it is translated, reflected, or rotated, but its location on the coordinate grid changes.
Therefore, the size of a figure remains constant when it is translated, reflected, or rotated, but its location on the coordinate grid changes.

what is the difference between an independent variable and a dependent variable and how does the independent and dependent variables relate to a graph
Answer:
Remember, the values of both variables may change in an experiment and are recorded. The difference is that the value of the independent variable is controlled by the experimenter, while the value of the dependent variable only changes in response to the independent variable
Step-by-step explanation:
Answer:
The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.

Step-by-step explanation:
Assuming the dilatation is centred at the origin.
Then multiply the coordinates of each point by the scale factor, that is
(- 2, 3 ) → (- 2(2), 3(2) ) → (- 4, 6 )
(3, 4 ) → (3(2), 4(2)) → (6, 8 )
(4, - 1 ) → (4(2), - 1(2)) → (8, - 2 )
Rectangle QUAD has coordinates Q(0,0), U(0,3), A(7,3), and D(7,0). Q'U'A'D' is the image of QUAD after a dilation with center (0,0) and scale factor 6. What are the coordinates of point U '?
Answer:
22
Step-by-step explanation:
After dilation with center (0,0) and scale factor 6 new coordinates of point U are ( 0, 18).
What is dilation?" Dilation is defined as to resize the given geometrical shape with given scale factor."
Formula used
Scale factor
= (Dimensions of new shape) ÷ (Dimensions of original shape)
According to the question,
Given rectangle QUAD,
Coordinates of Q(0,0)
Coordinates of U(0,3)
Coordinates of A(7,3)
Coordinates of D(7,0)
Q'U'A'D' is the image of QUAD after a dilation with center (0,0) and scale factor 6.
New Coordinates of Q'(0,0)
New Coordinates of U'(0,18)
New Coordinates of A'(42,18)
New Coordinates of D'(42,0)
Hence, after dilation with center (0,0) and scale factor 6 new coordinates of point U are ( 0, 18).

I hope this helped ;DIn a relay race, each runner completes the circuit 9 seconds faster than the previous one. If the first athlete runs his lap in 4 minutes 37 seconds, how many minutes does it take in total for the team of 8 competitors to finish the race? Give your answer correct to the nearest minute. [Answer format: integer, no units]
Answer:
31 minutes
Step-by-step explanation:
Here, we have 8 competitors with the previous runner outrunning the present by 9 seconds
1st runner time = 4 minutes 37 seconds
2nd runner time = 4 minutes 37 seconds - 9 seconds = 4 minutes 28 seconds
3rd runner time = 4 minutes 28 seconds - 9 seconds = 4 minutes 19 seconds
4th runner time = 4 minutes 19 seconds - 9 seconds = 4 minutes 10 seconds
5th runner time = 4 minutes 10 seconds - 9 seconds = 4 minutes 1 second
6th runner time s= 4 minutes 1 second - 9 seconds = 3 minutes 52 seconds
7th runner time = 3 minutes 52 seconds - 9 seconds = 3 minutes 43 seconds
8th runner time = 3 minutes 43 seconds - 9 seconds = 3 minutes 34 seconds
The total time is the addition of all the times
For clarity sake, we shall be adding all the minutes together and all the seconds together;
That will be ;
(4 * 6) + 3 minutes + ( 34 + 43 + 52 + 1 + 10 + 19 + 28 + 37)
= 27 minutes + 224 seconds
We need to convert 224 seconds to minutes
Since 60 seconds make one minute; we have
224 - 60(3) = 3 minutes and 44 seconds
Let’s add this to the minutes we had before
That would be;
27 minutes + 3 minutes + 44 seconds
= 30 minutes 44 seconds
since 44 seconds is greater than 1/2 minute (30 seconds), we can approximate it to 1 minute
So the total time is 30 minutes + 1 minute = 31 minutes
