What is m∠B?

There is a seven sided polygon ABCDEFG in which the measure of angle BCD is 148 degrees, the measure of angle DEF is 142 degrees, the measure of angle EFG is 130 degrees, the measure of angle FGA is 129 degrees, and the measure of angle GAB is 120 degrees. Angle CDE is a right angle.

In the function rule p(t) - 700, the number 700 represents a constant value that is subtracted from the value of the function p(t).

Assuming that p(t) is a function of time t, it is possible that p(t) represents a physical quantity such as the population of a city, the price of a stock, or the number of customers in a store, among other things. If we know what p(t) represents, we can interpret the meaning of 700 in the context of the situation.

For example, if p(t) represents the population of a city, then p(t) - 700 would represent the difference between the population and a reference value of 700. This could mean that 700 is the estimated minimum viable population of the city, or it could represent a reference population for comparison with other cities.

If p(t) represents the price of a stock, then p(t) - 700 would represent the difference between the stock price and a target value of 700, such as a price floor or a strike price.

In general, the meaning of 700 in the function rule p(t) - 700 depends on the specific context of the situation and the physical quantity that p(t) represents.

At 12 noon the count in a bacteria culture was 400, at 3:00 pm the count was 1200. The bacteria count at 9 am, rounded off to the nearest bacterium, was 255.

The problem involves finding the bacteria count at 9 am, given the counts at 12 noon and 3 pm, and assuming that the bacteria culture obeys the population growth law.

To solve the problem, we use the population growth law, which states that the rate of growth of a population is proportional to the size of the population at any given time. This can be expressed as a differential equation, and its solution gives the population as a function of time.

Assuming the bacteria culture grows exponentially between 9 am and 3 pm, we can use the population growth law to find the bacteria count at 9 am. Let the initial count at 9 am be denoted by P, and let the growth rate be denoted by r.

Then we have:

P * (1 + r)^3 = 1200

Solving for P, we get:

P = 1200 / (1 + r)^3

Similarly, assuming the bacteria culture grows exponentially between 12 noon and 3 pm, we have:

400 * (1 + r)^3 = 1200

Solving for r, we get:

r = (1200/400)^(1/3) - 1

Plugging this value of r into the equation for P, we get:

P = 1200 / (1 + (1200/400)^(1/3) - 1)^3

Using a calculator, we get:

P ≈ 255

Answer:

Expected amount = $1.50

Step-by-step explanation:

Let's get a couple of definitions out of the way to understand how to compute the expected value given probabilities

Random Variable is a set of possible values from a random experiment.
We usually denote a random variable using the sets of possible values that the variable can take.

When we toss a fair die, the probability of getting a single number = 1/6 since there are 6 possible outcomes

The probability of getting 2 given numbers say 1 or 2 is twice 1/6 = 2 x 1/6 = 2/3 and so on

The expected value of each outcome is the value attached to each outcome x probability of that outcome

As an example, P(1 or 2) = 2/6 = 1/3

Payout = $3

Expected payout = 3 x 1/3 = $1

The table below summarizes the outcomes, probabilities, payouts and expected payouts

Outcome             Probability              Payout              Expected Payout
                                                                                     (Payout x probability)

X = {1 or 2}            2/6 = 1/3                  $3                     $3 x 1/3 = $1

X = {3}                       1/6                       $5                     $5 x 1/6 = $5/6

X = {4 or 5}           2/6 = 1/3                  $0                      $0 x 1/3 = $0

X = {6}                        1/6                      -2$                     -$2 x 1/6 = -$2/6

The expected payout in the long run is the sum of the individual expected payouts

= $1 + $5/6 + $0 - $2/6    (5/6 - 2/6 = 3/6)

= $1 + $3/6             (3/6 = $0.50)

= $1 + $0.50

= $1.50

The expected value of the game is $2. This means that if you play the game many times, you can expect to win an average of $2 per game in the long run.

It is a branch of mathematics that deals with the occurrence of a random event.

To determine whether you should play the game, we need to calculate the expected value of the game.

The expected value is the sum of the product of each outcome and its probability.

The outcomes and their corresponding probabilities are:

Win $3 with probability 1/3 (if the number is 1 or 2)

Win $5 with probability 1/6 (if the number is 3)

Win $0 with probability 2/6 = 1/3 (if the number is 4 or 5)

Lose $2 with probability 1/6 (if the number is 6)

Using these probabilities and outcomes, we can calculate the expected value as:

Expected value = (3 × 1/3) + (5 × 1/6) + (0 × 1/3) + (-2 × 1/6)

= 1 + 5/6 - 1/6

= 1.666

= 2

Hence, the expected value of the game is $2. This means that if you play the game many times, you can expect to win an average of $2 per game in the long run.

The area of the figure is 254.8 m²

Area is the region occupied by an object.

Since the figure is a rectangle and containing two semi-circles, we find the area of the figure by finding the area of the rectangle and the two semi-circles.

The area of the rectangle is given by A = LW where

Given that

A = LW

= 16 m × 12 m

= 192 m²

The area of a semi-circle with diameter d is A = πd²/4

Now for the first semi-circle, its diameter d' = 8 m.

So, its area A' =  πd'²/4

=  π(8 m)²/4

= π64 m²/4

= 16π m²

= 16 ×3.14 m²

= 50.24 m²

Also, for the fsecond semi-circle, its diameter d" = 4 m.

So, its area A' =  πd'²/4

=  π(4 m)²/4

= π16 m²/4

= 4π m²

= 4 × 3.14 m²

= 12.56 m²

So, the area of the figure is A₁ = A + A' + A"

= 192 m² + 50.24 m² + 12.56 m²

= 254.8 m²

Let's assume that, we are planting x apple trees extra per acre. So, net 10x apple will be less.

Let say, total number of apples = y

Then, y = (30+x)×(400–10x)

For, optimum number of trees, let's do the differentiation of the above equation with respect to x.

d(y)/d(x) = (400–10x)×1 + (30+x)×(-10)

= 400–10x-300–10x

= 100–20x …………..(1)

For mimima or maxima, the above equation must be equal to 0.

The range of 85-95 is within one standard deviation of the mean in a normal distribution with a mean of 90 and a standard deviation of 5,the correct answer is c. 85-95.

The normal distribution is a bell-shaped curve that is centered around the mean and symmetrical about the mean. In a normal distribution with a mean of 90 and a standard deviation of 5, one standard deviation of the mean would be 85-95. This means that any score within this range is within one standard deviation of the mean.

To calculate this, we first look at the mean, which is 90. To find the value of one standard deviation from the mean, we need to subtract 5 from 90 to get 85. To find the upper limit of one standard deviation, we add 5 to 90 to get 95. Therefore, any score between 85 and 95 is within one standard deviation of the mean.

To summarize, any score within the range of 85-95 is within one standard deviation of the mean in a normal distribution with a mean of 90 and a standard deviation of 5. Therefore, the correct answer is c. 85-95.

Step-by-step explanation:

The lines are neither parallel nor perpendicular.

Two lines are parallel if and only if they have the same slope. Two lines are perpendicular if and only if the product of their slopes is -1.

To find the slope of a line given in the form of Ax + By = C, we can rearrange the equation into slope-intercept form (y = mx + b), where m is the slope.

The first line, 6x - 12y = 24, can be rearranged into slope-intercept form as follows:

12y = -6x + 24

y = -0.5x + 2

The slope of the first line is -0.5.

The second line, 4x + 2y = 8, can be rearranged into slope-intercept form as follows:

2y = -4x + 8

y = -2x + 4

The slope of the second line is -2.

Since the product of the slopes is not -1, the lines are not perpendicular. And since the slopes are not the same, the lines are not parallel. So, the lines are neither parallel nor perpendicular.
