Find the indicated probability.

​In one town, 39% of all voters are Democrats. If two voters are randomly selected for a survey, find the probability that they are both Democrats. Round to the nearest thousandth if necessary.

Answers

Using it's concept, it is found that there is a 0.152 = 15.2% probability that they are both Democrats.

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Two voters are selected, each with 39% probability of being Democrats, hence the probability of both being Democrats is given by:

p = (0.39)² = 0.152.

0.152 = 15.2% probability that they are both Democrats.

Solve the following using the distributive property:
8x+12=2(x-3)​

Answers

Answer:

x = - 3

Step-by-step explanation:

8x + 12 = 2(x - 3) ← distribute the parenthesis by 2

8x + 12 = 2x - 6 ( subtract 2x from both sides )

6x + 12 = - 6 ( subtract 12 from both sides )

6x = - 18 ( divide both sides by 6 )

x = - 3

Answer:

x = -3

Step-by-step explanation:

you first distribute 2(x-3) which gives you 2x-6 so 8x+12=2x-6.

next you move the terms to the correct side so you subtract 12 from the left side and subtract 2x from the right side then move them to the other side so you end up with 8x-2x=-6-12.

then you combine like terms so you will have 6x=-18.

then divide both sides by 6 which gives you x = -3.

8x+12=2(x-3)

8x+12 = 2x-6

8x-2x = 6-12

6x = -18

x = -3

Step-by-step explanation:

For each of the two right triangles, by the Pythagorean theorem, she shared side is of length 15. So, the area of each of the top two rectangles is (½)(8)(15), so their combined area is 120.

Moving onto the trapezoid, we can use the formula for the area of a trapezoid to determine its area is (½)(14+16)(4)=60.

So, the answer is 120+60=180.

Suppose a batch of steel rods produced at a steel plant have a mean length of 176 millimeters, and a variance of 100. If 446 rods are sampled at random from the batch, what is the probability that the mean length of the sample rods would differ from the population mean by greater than 0.65 millimeters

Answers

The probability that the mean length of the sample rods would differ from the population mean by greater than 0.65 mm is 0.1698 or 16.98%.

Mean length of the population (μ) = 176 mm.

Variance of the population (σ²) = 100.

Therefore, the standard deviation of the population (σ) = √100 = 10.

The sample size (n) = 446.

The mean of the sample = the mean of the population = μ = 176 mm.

The standard deviation of the sample (s) = σ/√n = 0.4735137.

We are asked to find the probability that the sample rods would differ the population mean by greater than 0.65 mm, that is,

either the length of the sample rods is less than (176 - 0.65) =175.35

or the length of the sample rods is more than (176 + 0.65) = 176.65.

This can be shown as P(X < 175.35 or X > 176.65) = 1 - P(175.35 < X < 176.65) = 1 - Normalcdf(175.35,176.65,176,0.4735137) = 1 - 0.8302 = 0.1698 or 16.98%.

Thus, the probability that the mean length of the sample rods would differ from the population mean by greater than 0.65 mm is 0.1698 or 16.98%.

Answers

The correct option is D, The relationship is not proportional because the ratio of pages to days is not constant.

What is a linear relationship?

A linear relationship is a relationship in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c.

A linear relationship with two variables, when graphed on the cartesian plane with axes of those variables, gives a straight line.

For the given relationship to be proportional, the number of pages read should be the same every day. Therefore, the ratio of the number of pages to the number of days should be equal.

85/1 = 85

170/2 = 85

The relation C= -31 t² - 80 t + 310 describes the cockroach population at
MCVI, where C is the number of cockroaches in thousands, and t is the time
in days. How many cockroaches are there at the start?

Answers

Answer:

310,000

Step-by-step explanation:

Since t represents time, the start would represent when no time has passed or in other words, when t=0, which is the y-intercept. You can plug in t as 0, but it's a bit redundant, since the y-intercept of a quadratic equation in the form: [tex]f(x)=ax^2+bx+c[/tex] will have a y-intercept at (0, c) where c is the constant, since whenever you plug in 0 as x, the ax^2 becomes 0 (since 0^2 = 0, and a * 0 = 0 since anything multiplied by 0... is 0) and the same thing goes for the bx, leaving the c alone. This means the y-intercept of the function is (0, 310) and since it's in the thousands there is 310,000 at the start

Please mark brainliest! Thanks!

Answer:

g(x)⁻¹ = √x + 3

Step-by-step explanation:

To find the inverse of an expression is to reverse the expression. This can be done by swapping the input and output variables. In other words, in g(x), you want to swap the places of the "x" variable the "y" variable.

Remember, g(x) = y.

y = (x - 3)²                              <----- Original function

x = (y - 3)²                              <----- Swap the variables

Now, you want to set the equation equal to "y" again. This can be done by rearranging/simplifying the expression.

x = (y - 3)²                              <----- Swapped variables

√x = √(y - 3)²                        <----- Take the square root of both sides

√x = y - 3                              <----- Eliminate parentheses from previous step

√x + 3 = y                             <----- Add 3 to both sides

If g(x)⁻¹ represents the inverse of g(x), the new function is:

g(x)⁻¹ = √x + 3
