i need help please and thank you !!
Answer:
y=2x-2
Step-by-step explanation:
When looking at the line, you can see the y-intercept is at the point (0,2) so it meets the y-axis at that point. Then, when you look at the pattern between the points on the line, you can see the line has a slope of 2, making the answer y=2x-2
We roll two dice. Find the conditional probability that at least one of the numbers is even, given that the sum is 8.
Answer:
0.599 or 0.6
Step-by-step explanation:
We will be using the alphabets M and N in this solution.
Let M be that one of the number is even
Let N be that the sum is 8
The sample space of these two dice when rolled is 36
Probability of 8 and even numbers is (4,4),(6,2),(2,6)
= 3/36 = 0.08333
Probability of sum of 8 is (4,4),(5,3)(3,5),(6,2),(2,6)
= 5/36 = 0.1389
P(M|N) = 0.08333/0.1389
= 0.599
Approximately 0.6

Let A, B, and C be any sets with A ⊆ C and B ⊆ C. Show that A – B = A ∩ (C – B).
Can you help me prove the proof holds true?
I assume A - B is the complement of B in A, i.e. all elements of A that do not belong to B.
To prove equality between two sets, you have to show they are subsets of one another. To prove one set is a subset of another set, you have to show that any element in the first set belongs to the second set.
So, to show that A - B = A ∩ (C - B), you have to prove
• A - B ⊆ A ∩ (C - B)
• A ∩ (C - B) ⊆ A - B
Left to right:
Let x ∈ A - B.
By definition of set complement, x ∈ A and x ∉ B.
Since A ⊆ C, x ∈ C.
So x ∈ C - B, and by definition of set intersection, x ∈ A ∩ (C - B).
This proves A - B ⊆ A ∩ (C - B).
Right to left:
Let x ∈ A ∩ (C - B).
By definition of set intersection, x ∈ A and x ∈ C - B.
By definition of set complement, x ∈ C and x ∉ B.
Again by definition of complement, x ∈ A and x ∉ B means that x ∈ A - B.
This proves A ∩ (C - B) ⊆ A - B.
Both sets are subsets of one another, so A - B = A ∩ (C - B).

Do 1.7 and 1.700 have the same value? In a full sentence, explain why or why notw
Answer: Yes
1.7 and 1.700 have the same value because zeros have no value, and without the zeros, 1.700 would turn into 1.7. It is not like there is another number that is not zero after the two zeros either.

2) Major league baseball salaries averaged $3.26 million with a standard deviation of $1.2 million in a certain year in the past. Suppose a sample of 100 major league players was taken. What was the standard error for the sample mean salary
Answer:
Standard error for the sample = $0.12 million
Step-by-step explanation:
Given:
Mean = $3.26 million
Standard deviation = $1.2 million
Number of sample = 100
Find:
Standard error for the sample
Computation:
Standard error for the sample = Standard deviation / √Number of sample
Standard error for the sample = 1.2 / √100
Standard error for the sample = $0.12 million
What’s the answer to these?

Step-by-step explanation:
5. A turtle dives towards deeper water at a rate of 8 inches per second. It continues for a total of 16 seconds.
Which expression represents this situation?
We are given Maya's diving rate as:
8 inches per second
Because she is diving, the rate carries a negative sign hence, the expression of the situation is:
16 × -8
= 16(-8)
Option A 16(-8) is correct
6. Marisa has $26 in her purse. She pays $5 for lunch. Which expression represents this situation?
Amount she has =$28
She pays = $5
Hence, $26 + (-$5)
= $26 - $5
Option C. 26 + (-5) is correct
7. Aaron turned on his air conditioning and the temperature in his apartment decreased 6 degrees.
Write an integer to represent the change in temperature.
A decrease or drop in temperature is always expressed as a negative sign. Hence,
Option B. -6° is correct

How can you use tables and graphs to show equivalent ratios?
Ratio table can help you find equivalent ratios in order to solve problems.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Ratio tables show equivalent ratios between two quantities. You can create a ratio table by multiplying (or dividing) both quantities in the ratio by the same value to find an equivalent ratio.
A ratio table can help you find equivalent ratios in order to solve problems.
If a straight line passing through the origin has same ratios or which has same slope at all points.

The height of a triangle is increasing at a rate of 3 cm/min while the area of the triangle is increasing at a rate of 11 square cm/min. At what rate is the base of the triangle changing when the height is 5 centimeters and the area is 10 square centimeters
Answer:
2cm/minStep-by-step explanation:
The Area of a triangle is expressed as:
A = 1/2 bh
b is the base of the triangle
h is the height of the triangle
Given
dh/dt = 3cm/min
dA/dt = 11cm²/min
height h = 5cm
Area = 10cm²
Get the base first
10 = 1/2b(5)
20 = 5b
b = 20/5
b = 4cm
Differentiating the area with respect to time
A(b, h) = 1/2 bh
According to product rule
dA/dt = 1/2{b dh/dt + h db/dt}
Substitute the given parameters and get db/dt
11 = 1/2{4(3)+5db/dt}
11 = 1/2{12+5 db/dt}
11 = 6 + 5/2 db/dt
11-6 = 5/2 db/dt
5 = 5/2 db/dt
1 = 1/2 db/dt
cross multiply
2 = db/dt
db/dt = 2cm/min
Hence the rate at which the base of the triangle is changing id 2cm/min
If you copy a document on a​ machine, you should get a similar copy. Suppose you want to reduce a document to of its original size and you first reduce it by ​%. By what percent do you need to reduce the copy to obtain the desirable​ size?
Answer:
the numbers are missing, so I looked for a similar question:
If you copy a document on a machine, you should get a similar copy. suppose you want to reduce a document to 1/6 of its original size, and first reduce it by 25%. By what percent do you need to reduce the copy to obtain the desirable size?
You want the copy to be 1/6 of the original size = 16.67%
Since you first reduced the copy by 25%, the image is now 75% of its original size. In order to finally obtain a copy that is 16.67% of the original size, you must reduce this second copy by 1 - (16.67%/75%) = 77.78% ≈ 78%.
we can check our answer:
size of second copy x (1 - reduction)
0.75 x (1 - 0.7778) = 0.1667
