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.

For the past three months, Grace used her cell phone for 43 minutes, 62 minutes, and 57 minutes. How many minutes would she have to use her cell phone this month for the average usage over the four months to be 55 minutes? Be sure to include units in your answer
Answer:
Step-by-step explanation:
If they want the average for four months to be 55 minutes, this means that the total of the four months = 55 x 4
Total of four months = 220 minutes
They already told us that the three previous months she used her cellphone for 43 minutes, 62 minutes and 57 minutes.
All you have to do now is subtract everything from the total of the four months.
4th month = 220 - 43 - 62 - 57
= ? Minutes
What is the area of the pentagon shown?
Answer:
The area of the pentagon is: 354
Step-by-step explanation:
First draw two auxillery lines in the upper left hand corner to make a rectangle, and a right triangle.
Now that we have a rectangle we can find its area:
18·20=360
To find the lengths of the triangle sides:
20-16=4
18-15=3
Area of a right triangle formula: (leg a · leg b)/2
3·4=12 12/2=6
Now subtract the area of the triangle from the rectangle:
360-6=354
Answer:
354

A tanker truck fills the gas station’s reservoir at the rate of 1212 gallons per minute.
If the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir?
Round your answer to the nearest tenth. Enter your answer in the box.
how meny minutes
Answer:
1.73 seconds ( 0.0289 minutes : 2.89 × 10^-2 minutes)
Step-by-step explanation:
35/(1212/60) = 1.73267327 ≈ 1.73 seconds.
1.73267327/60 = 0.0288778878 ≈ 0.0289 = 2.89 × 10^-2 minutes

Paula knits hats. The number of hats h she can knit varies directly with the amount of yarn (y) in yards she has. The constant of proportionality is 42. Write an equation to represent the relationship between the number of yards of yarn Paula has and the number of hats she can knit.
Answer:
The equation showing the relationship between the number of yards of yarn Paula has and the number of hats she can knit is ;
h = 42y
Step-by-step explanation:
Here, we want to write an equation;
From the question, we are told that the number of hats h that can be knitted is directly proportional to the amount of yarn in yards
Since it is a proportional relationship;
h = k * y
where k is the constant of proportionality given as 42
Hence;
h = 42 * y
h = 42y

What do we do to the inequality sign when we multiply or divide by a negative?
Steve Forbes ran for US president in 1996 and 2000 on a platform proposing a 17% flat
tax, that is, an income tax that would simply be 17% of each tax payer's taxable
income. Suppose that Alice was single in the year 2016 with a taxable income of $40000.
a) What was Alice's tax? Use Tax table on page 292.
b) If the 17% flat tax proposed by Mr. Forbes had been in effect in 2016, what
would Alice's tax have been?
5(2x+3)+2(4x –1)

Find the results of the given vector subtractions for u = <-8, 4> and V = <2,7>.
Answer:
see explanation
Step-by-step explanation:
- u - v
= - < - 8, 4 > - < 2, 7 > ← multiply each component of u by - 1
= < 8, - 4 > - < 2, 7 > ← subtract corresponding elements
= < 8 - 2, - 4 - 7 >
= < 6, - 11 >
----------------------------------------------------------
u - v
= < - 8, 4 > - < 2, 7 > ← subtract corresponding elements
= < - 8 - 2, 4 - 7 >
= < 6, - 3 >
-----------------------------------------------------------
v- u
= < 2, 7 > - < - 8, 4 > ← subtract corresponding elements
= < 2 - (- 8), 7 - 4 >
= < 2 + 8, 7 - 4 >
= < 10, 3 >
