The baseball team has a double-header on Saturday. The probability that they will win both games is 18%. The probability that they will win just the first game is 60%, What is the probability that the team will win the 2nd game given that they have already won the first game?
Answers
60% as a decimal is 0.6
18% as a decimal is 0.18
0.6 times 30% or 0.3 is 0.18
Let the event to win the first game is F and to win the second game is S.
This question is from conditional probability and hence we use the below formula.
[tex]P(S/F)=\frac{P(F and S) }{P(F)}[/tex]
Now, we have been given that
[tex]P(F and S)=0.18\\ P(F)=0.60[/tex]
On substituting these given values in the formula, we get
[tex]P(S/F)=\frac{0.18}{0.60} \\ \\ P(S/F)=0.3=30\%[/tex]
Therefore, the probability for winning the second game is 30%

If a = -12/5, then 5x + 2y = 6 and 3x - ay = 4 are parallel.
Answers
5x +2y =6
Add -2y to both sides
5x=−2y+6
Divide both sides by 5
x=−2/5y + 6/5
that into the second equation:
3(−2/5y+6/5)+12/5y =4
simplify
6/5y+18/5 =4
Add (-18)/5 to both sides
6/5y=2/5
divide both sides by 6/5
y = 1/3
substitute 1/3 for y in x = -2/5y +6/5 to solve for x
x = -2/5(1/3) +6/5
x = 16/15
so x = 16/15 and y = 1/3
now replace both x and Y in each of the original equations to check the answers:
5(16/15) +2(1/3) = 5 1/3 + 2/3 = 6 true
3(16/15) - -12/5(1/3) = 4 true
so they are parallel

If the sides of two similar figures have a similarity ratio of 5/3, what is the ratio of their perimeter?
Answers
The ratio of the perimeters of two similar figures with a similarity ratio of 5/3 is also 5/3. This ratio applies to all corresponding linear measurements, including perimeter, when figures are similar.
If the sides of two similar figures have a similarity ratio of 5/3, the ratio of their perimeters will also be 5/3. This is because the perimeter of a figure is simply the sum of its side lengths, and since all corresponding sides are in the same ratio for similar figures, the perimeters will be in the same ratio too.
For example, if one figure has a side length of 5 units, its similar figure will have the corresponding side length of 3 units (given the ratio). If you add up all the sides for the first figure and all the sides for the second figure, the sums will still maintain that 5/3 ratio due to the proportional nature of similarity in geometry.

Is the sequence geometric? If so, identify the common ratio. 1/5, 2/15, 4/45, 8/135, 16/405
Answers
now 2/15/1/5 = 2/3
and 4/45/2/15 = 2/3
therefore 2/3 is the common ratio
So have the sequence: 1/5,2/15,4/45,8/135,16/405To check if the sequence is geometric, we are going to find its common ratio; to do it we are going to use the formula: r=(an)/(an-1)where r is the common ratio an is the current term in the sequence an is the previous term in the sequenceIn other words we are going to divide the current term by the previous term a few times, and we will to check if that ratio is the same:
For an= 2/15 and an-1=1/5 :r=(2/15)/(1/5)r=2/3
For an=4/45 and an-1=2/15:
r=(4/45)/(2/15)
r=2/3
For an=8/135 and an-1=4/45 :r=(8/135)/(4/45)
r=2/3
As you can see, we have a common ratio!
We can conclude that our sequence is a geometric sequence and its common ratio is 2/3

Which is the equation in slope-intercept form for the line that passes through (3,3) and is parallel to x + 3y = 4?
Answers
Let's first set up the equation in general form
ax + by = c
The line is parallel to x + 3y = 4, and therefore the formula is x + 3y = c.
The line passes through the point (3, 3) so we can plug in those values into the formula.
3 + 3 × 3 = c
3 + 9 = c
12 = c
c = 12
Now we have found the equation of our formula:
x + 3y = 12
Rewrite the formula.
First subtract x from both sides.
3y = -x + 12
Divide both sides by 3.
y = -1/3x + 4
Therefore, the first answer is correct.

What type of association would you expect to see between the amount of fog in the sky and the distance that a pilot can see? A) Positive association B) Negative association C) No association D) There is not enough information to tell
Answers
There is a negative association between the amount of fog in the sky and the distance a pilot can see; i.e. the higher the amount of fog, the lower the visibility distance.
Explanation:The question primarily asks about the association between the amount of fog in the sky and the distance a pilot can see. In general, the greater the fog, the lower the visibility distance for a pilot. Hence, there is a negative association between these two variables. When one variable (amount of fog) increases, the other variable (pilot's visibility distance) decreases.

Lisa arranges six square paintings as shown in the area of the arrangement is 225 cm² what would it cost Lisa to frame her arrangement at a cost of $.12 per centimeter
Answers
To frame Lisa's arrangement of six square paintings, the total cost would be $43.20.
Explanation:To find the cost of framing Lisa's arrangement, we need to calculate the perimeter of the arrangement and then multiply it by the cost per centimeter. Since the arrangement consists of six square paintings, we can calculate the side length of one square by taking the square root of the total area of 225 cm². The side length of one square is 15 cm, so the perimeter of one square is 4 multiplied by 15 cm, which is 60 cm. Since there are six squares, the total perimeter of the arrangement is 6 multiplied by 60 cm, which is 360 cm. Finally, we multiply the total perimeter by the cost per centimeter of $.12 to find the total cost of framing, which is 360 cm multiplied by $0.12, equaling $43.20.

To get this answer quickly, you subtract the given angle (37) from 180 to get 180-37 = 143
The more longer answer would look something like this
x+37 = 180 .... the two supplementary angles add to 180 degrees
x+37-37 = 180-37 .... subtract 37 from both sides
x+0 = 143

What is the associative property
Answers
Example 1:
1 + 2 + 3
We can solve this by first doing 1 + 2 = 3, and then adding 3 + 3 = 6. OR we can start with 2 + 3 = 5, and add 5 + 1 = 6. We can even do, 3 + 1 = 4, then add 4 + 2 = 6. Either way, we end up with the same correct answer.
Example 2:
1 x 2 x 3
Same thing applies to multiplication. We can start by doing 1 x 2 = 2, and then 2 x 3 = 6. OR we can do 2 x 3 = 6, then 6 x 1 = 6. Just like the one above, we can also do, 3 x 1 = 3, then 3 x 2 = 6. Either way you group them, you get the same answer.
Example 3:
- 1 - 2 - 3
We can do - 1 - 2 = - 3, then - 3 - 3 = - 6. OR - 1 - 3 = - 4, then - 4 - 2 = - 6. OR - 2 - 3 = - 5, then - 5 - 1 = - 6. Again, same answer, three different ways to group it.
