i think it is A

Step-by-step explanation:

a) Igor's data point on the graph represents his salary and age after re-doing his medical training in the UK. b) The scatter graph might support the managing director's conclusion that salary is linked to age if there is a positive correlation between age and salary. c) To make the conclusion more reliable, other factors like years of experience and specialization should be considered.

a) Igor's data point on the scatter graph would represent his salary and age after re-doing his medical training in the UK. This data point would likely be separate from the other data points for experienced surgeons in the UK.

b) The scatter graph might support the managing director's conclusion that salary is linked to age if there is a positive correlation between age and salary for the surgeons in the data. This means that as age increases, salary also tends to increase.

c) To make the conclusion more reliable, additional factors should be taken into account, such as years of experience, specialization, and performance ratings, as these factors may also contribute to salary differences among surgeons.

The 10th term in the geometric sequence can be found by using the common ratio of 1/3 and applying it to the formula T(n) = a1 * r^(n-1). The 10th term is determined to be 1/9.

Calculating the 10th Term of a Geometric Sequence

To find the 10th term in the geometric sequence (2187, 729, 243, 81, 27), we first need to determine the common ratio (r). We can find r by dividing any term by its preceding term. Using the second and first terms, we get:

r = 729 / 2187 = 1/3

With the common ratio identified, we can use the formula for the nth term of a geometric sequence:

T(n) = a1 * r^(n-1)

Where a1 is the first term of the sequence and n is the term number. So, the 10th term (T(10)) is calculated as:

T(10) = 2187 * (1/3)^(10-1) = 2187 * (1/3)^9

To calculate this, we simply apply the exponent to the common ratio:

T(10) = 2187 * 1/19683 = 2187 / 19683 = 1/9

Therefore, the 10th term of the geometric sequence is 1/9.

Answer:

The probability of getting a nickel, then a dime is 2/21

Step-by-step explanation:

No. of pennies = 9

No. of nickels = 10

No. of dimes = 12

No. of quarters = 5

Total items = 9+10+12+5=36

So, Probability of getting nickel on first draw = [tex]\frac{10}{36}[/tex]

Now the nickle in not replaced

So, Total items = 36-1 = 35

So, Probability of getting dime on second draw =[tex]\frac{12}{35}[/tex]

So, the probability of getting a nickel, then a dime = [tex]\frac{10}{36} \times \frac{12}{35}=\frac{2}{21}[/tex]

Hence the probability of getting a nickel, then a dime is 2/21

Final answer:

The probability of selecting a nickel followed by a dime from a jar filled with various coins, without replacement, is calculated to be 2/21.

Explanation:

The question involves calculating the probability of selecting a nickel and then a dime from a jar containing various coins without replacement. Initially, there are 9 pennies, 10 nickels, 12 dimes, and 5 quarters, totaling 36 coins. To find the probability of selecting a nickel and then a dime, we first calculate the probability of picking a nickel, then multiply it by the probability of picking a dime afterwards.

Probability of selecting a nickel first: 10/36 (as there are 10 nickels out of 36 coins).

After a nickel is selected, there are 35 coins left, including 12 dimes. So, the probability of selecting a dime next is 12/35.

Therefore, the probability of selecting a nickel and then a dime, in that order, without replacement is (10/36) * (12/35) = 120/1260 = 1/10.5, simplifying to 2/21 when expressed in fraction form.

1.5(x + 4) - 3 = 4.5(x - 2)

Distribute

1.5x +6 -3 = 4.5x -9

Combine like terms

1.5x +3 = 4.5x -9

Subtract 1.5x from each side

1.5x -1.5x +3 = 4.5x -1.5x -9

3 = 3x-9

Add 9 to each side

3+9 = 3x-9+9

Answer:

B. 4

Step-by-step explanation:

Remember the acronym: PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction).

P: The expressions in the parentheses are not solvable as they are.

E: There are no exponents.

M: On the left, multiply 1.5 by x, giving you 1.5x, and by 4, giving you 6. We now have 1.5x + 6 -3 on the left. On the right, do the same. Multiply 4.5 by x, giving you 4.5x, and then multiply 4.5 by -2, giving you -9. Our expression is now 1.5x + 6 - 3 = 4.5x - 9.

D: There is no division in the problem.

A: There is no addition in the problem.

S: Subtract the 3 from the 6 on the left:. We now have 1.5x + 3 = 4.5x - 9.

Now that were all simplified, lets solve. Subract 1.5x from both sides so that only one side has x, so it can be solved. We now have 3 = 3x - 9.

Add 9 to both sides, to simplify even further. We now have 12 = 3x.

For the final step, we need to isolate x. To do this, we need to get rid of the coefficient. We know that 3 and x are being multiplied, so we can just divide to undo it. Keep in mind that we need keep both sides equal, so we divide both sides. By what? By 3. Now, we have our final answer:

x = 4

Answer: D.

Step-by-step explanation:

First, find the area of the two squares:

The photograph: (-3, -2), (-2, 2), (2, 1), and (1, -3).

The square is diagonally aligned, so we need to find the length between two points in order to find the area.

I will use (1, -3) and (2, 1).

There is a 1 unit length and a 4 unit height. We can use the Pythagorean theorem to find the hypotenuse of the triangle, which is the length of the square's side:

1^2 + 4^2 = x^2

1 + 16 = x^2

x = square root of 17

The side length for the square of the photograph is the square root of 17, so the area of the photograph is 17 units^2.

The red paper has side lengths of 8. The distance between (-4, 4) and (4, 4) is 8 units wide, so we do not need to use the Pythagorean theorem.

Now that we know the area of the red paper and photograph, you can subtract the area to find the red paper with the hole:

64 - 17 = 47 square units.

Answer:

D

Step-by-step explanation:

Let's plot these points (see attachment).

We need to find the area of the paper and then the area of the photograph and subtract the photograph area from the red paper area.

The area of the big paper is easy; the side lengths of the square are 8 by 8, so the area is 8 * 8 = 64 square units.

Now, to find the area of the photograph, we just need the length of one side because it's a square. We use the distance formula between any two adjacent points; let's do (-2, 2) and (2, 1):

d = [tex]\sqrt{(2-1)^2+(-2-2)^2} =\sqrt{1+16} =\sqrt{17}[/tex]

Then the area is (√17)² = 17.

Subtract 17 from 64:

64 - 17 = 47

The area is 47 square units, or D.

The point where two lines meet is known as an angle. The value of x if OA is perpendicular to OC is 30 degrees

The point where two lines meet is known as an angle.. From the given diagram;

(180 - 4x) + x = 90

Simplify the result

180 - 3x = 90

Subtract 180 from both sides

-3x = 90 - 180

-3x = -90

Divide both sides by -30

x = 90/3

x =30degrees

Hence the value of x if OA is perpendicular to OC is 30 degrees

Answer:

i think this is how you find it but i apologize if im wrong

Step-by-step explanation:

Use binomial probability since there are only two possibilities: success and failure, where success represents getting a heads, and tails being a fail. Therefore we are trying to find P(X=2), which is (42)⋅(0.5)2⋅(0.5)2=0.375.

The probability that you get two or more coins that land heads up is 0.6875.

Theoretical probability is an approach in probability theory that is used to calculate the probability of an outcome of a specific event.

The following histogram shows the theoretical probability of the number of heads you might get after flipping for coins simultaneously.

If you were to flip four coins what is the probability that you get two or more coins that land heads up is;

Probability = flip 0 coin + flip 1 coin + flip 2 coin

Probability = 0.375 + 0.25 + 0.0625

Probability = 0.6875

Hence, the probability that you get two or more coins that land heads up is 0.6875.
