What is the solution to y = 0.7x for the replacement set x = {2}?.

1 answer:

7 0

The question ask to solve and compute the said problem if x = 2 and the equation is y=0.7x. In that alone, the value of y is 1.4 so it means its solution, by means of representing it coordinate, it should be (2,1.4). I hope you are satisfied with my answer and feel free to ask for more

What are the powers of 3 through 1000? AND DONT JUST SAY A FEW I NEED ALL OF THEM

galben [10]

Answer:

1, 3, 9, 27, 81, 243, 729

Step-by-step explanation:

The powers of 3 are:

$3^0 = 1$

$3^1 = 3$

$3^2 = 9$

$3^3 = 27$

$3^4 = 81$

$3^5 = 243$

$3^6 = 729$

$3^7 = 2187$

And so on...

So through 1000: 1, 3, 9, 27, 81, 243, 729

The following data represent the number of people aged 25 to 64 years covered by health insurance (private or government) in 2

Yuri [45]

The mean age is equal to: 44.09.

The standard deviation is equal to: 10.07.

<h3>How to determine the mean age and standard deviation?</h3>

First of all, we would determine the median of each class interval as follows:

Median 1 = (25 + 34)/2 = 29.5

Median 2 = (35 + 44)/2 = 39.5

Median 1 = (45 + 54)/2 = 49.5

Median 1 = (55 + 64)/2 = 59.5

Next, we would calculate the mean age by using this mathematical expression:

Mean age = ∑fx/∑f

Substituting the given parameters into the formula, we have;

Mean age = [(24.3 × 29.5) + (36.1 × 39.5) + (36.7 × 49.5) + (20.9 × 59.5)]/(24.3 + 36.1 + 36.7 + 20.9)

Mean age = [716.85 + 1,425.95 + 1,816.65 + 1,243.55]/118

Mean age = [5,203]/118

Mean age = 44.09.

Now, we can calculate the standard deviation as follows:

Standard deviation, S = √((∑f(xi - μ)²/∑f)

Standard deviation, S = √((24.3 × (29.5 - 44.09)² + (36.1 × (39.5 - 44.09)² + (36.7 × (49.5 - 44.09)² + (20.9 × (59.5 - 44.09)²)/(24.3 + 36.1 + 36.7 + 20.9))

Standard deviation, S = √((5172.70 + 760.56 + 1,074.14 + 4,963.08)/118)

Standard deviation, S = √(11,970.48/118)

Standard deviation, S = √101.5

Standard deviation, S = 10.07.
