Explanation

The place value of 9 in 0.06945 is 9/10000, since the 9 is in the ten-thousandths place.

Here's how the place values work in this number:

•  0 is in the ones place
•  0 is in the tenths place
•  6 is in the hundredths place
•  9 is in the thousandths place
•  4 is in the ten-thousandths place
•  5 is in the hundred-thousandths place

So, the 9 is in the thousandths place, making its place value 9/10000.

Explanation

Since the population growth is exponential, the population P can be modeled as:

P = P0 x (1 + r)^t

where P0 is the initial population, r is the growth rate, and t is the time (in years).

Given that the initial population P0 = 20 and the population grew to 25 after 2 years, we can find the growth rate r:

25 = 20 x (1 + r)^2

Dividing both sides by 20:

1.25 = (1 + r)^2

Taking the square root:

1 + r = √1.25 = 1.125

Subtracting 1 from both sides:

r = 0.125

Now we can write the exponential growth function:

P = 20 x (1 + 0.125)^t

P = 20 x (1.25)^t

Explanation

The correct answer is: She asked me if I was happy in my new job.

This is because when converting direct speech to indirect speech, the present tense "are" becomes the past tense "was".

The correct indirect speech sentence is a polite and grammatically correct way to report the question.

Explanation

1. Average income of A and B is 50000, so their total income is:

2 x 50000 = 100000

2. Average income of B and C is 60000, so their total income is:

2 x 60000 = 120000

3. Average income of A and C is 55000, so their total income is:

2 x 55000 = 110000
Now, let's analyze the situation:

- A's income + B's income = 100000 ... (1)

- B's income + C's income = 120000 ... (2)

- A's income + C's income = 110000 ... (3)

We can add (1) and (3), and subtract (2) from the result:
(100000 + 110000) - 120000 = 90000
Simplifying this, we get:
190000 - 120000 = 70000
Now, divide by 2:
70000 / 2 = 35000
Now, add B's income and C's income (equation 2):
35000 + C's income = 120000
Subtract 35000 from both sides:
C's income = 85000
Now, subtract C's income from equation (3):
A's income + 85000 = 110000
Subtract 85000 from both sides:
A's income = 25000
Now, subtract A's income from equation (1):
25000 + B's income = 100000
Subtract 25000 from both sides:
B's income = 75000 - 25000
B's income = 55000
So, B's income is 55000.

Explanation

The number of ways to choose 2 students from a class of 20 students is represented by the combination formula:

C(20,2) = 20! / (2! x (20-2)!)

where ! denotes the factorial function.

Simplifying the formula, we get:

C(20,2) = (20 x 19) / 2

= 190

So, there are 190 ways to choose 2 students from a class of 20 students.
