The expected value of a single roll of this die is 4.5.

There is a probability of 1/8 that the number 1 will show.  

There is a probability of 1/8 that the number 2 will show.

and so on until you get to:

There is a probability of 1/8 that the number 8 will show.

The expected value is the sum of (probability that the number will show)*(the number) or in this case:

(1/8)*1 + (1/8)*2 + (1/8)*3 + ... +(1/8)*8

or

(1/8)*(1  2 + 3 + 4 + 5 + 6 + 7 + 8) = (1/8)*36 = 4.5

We could also use a shortcut to sum the numbers 1 through 8.  It is given by 8*(8+1)/2. The answer will remain the same, i.e., 4.5.

Hence, the expected value of a single roll of die in a octahedral die is 4.5.

If two polygons are similar, then they have the same shape but not necessarily the same size.

They can be either enlarged or reduced in size or reflected. Hence, even though the polygons are similar, they do not have to be drawn to scale.

The term scale refers to the ratio of any two corresponding lengths in two geometric figures, so if two figures are drawn to scale, the ratio of their corresponding lengths in the drawing is the same as the ratio of their corresponding lengths in the actual figures.

Therefore, if two polygons are similar but not drawn to scale, the drawing may not be an accurate representation of the actual figures, as the scaling information may not be consistent.

Maya is playing a trivia game with multiple choice questions. Each question has 222 correct answers among 555 answer choices. Maya has no idea what the answers to a certain question are, so she needs to choose two different answers at random.

The probability that maya's first guess is correct and her second guess is incorrect is 0.24.

From the question given above, the following data were obtained:

Correct answer (C) = 222

Total answer = 555

Incorrect answer (I) = 555 – 222 = 333

Next, we shall determine the probability that her 1st guess is correct.

Correct answer, nC = 222

Total answer, nS= 555

Probability of correct answer, P(C) =?

P(C) = nC / nS

P(C) = 222 / 555

Next, we shall determine the probability that her 2nd guess is incorrect

Incorrect answer, nI = 333

Total answer, nS = 554

Probability of incorrect answer, P(I) =?

P(I) = nI / nS

P(I) = 333 / 554

Finally, we shall determine the probability that her first guess is correct and her second guess is incorrect.

Probability of correct answer, P(C) = 222 / 555

Probability of incorrect answer, P(I) = 333 / 554

Probability of 1st correct and 2nd incorrect, P(C n I) =?

P(C n I) = P(C) × P(I)

P(C n I) = (222 / 555) × (333 / 554)

P(C n I) = 0.24

Hence the answer is, The probability that maya's first guess is correct and her second guess is incorrect is 0.24.

Answer:

mAngle 1 = 40°

Step-by-step explanation:

You can use Corresponding Angles to directly state Angle1 is 40°. If you have to prove it you can show that the horizontal lines are parallel bc they are both perpendicular to the same line (the vertical line in the middle)

OR...

Use vertical angles and supplementary angles to find all the six pack of angles right in the middle of the diagram. 40°, 50°, 90°, 40°, 50° 90° And the use the idea that a triangle's three angles must add up to 180°.

90+50+Angle1=180

140 + Angle1 = 180

Angle1 = 40°

Answer:

x = 70, y = 70

Step-by-step explanation:

The total degree is 180 for a triangle. The angles for x and y are the same since the sides are of the same length. So, it's (180 - 40) / 2 = 140 / 2 = 70.

Based on the above, the ice cream that was made at a rate of 0.2 hours per batch.

To know the rate at which the ice cream was made in hours per batch, one need to divide the total time taken by the number of batches produced.

So:

Rate (hours per batch) = Total time / Number of batches

Note that:

the total time taken = 7.6 hours,

the number of batches produced = 38.

Hence:

Rate (hours per batch) = 7.6 hours / 38 batches

= 0.2 hours per batch

The probability of fatal cancers for the stomach, bone marrow, and bone surface given a dose of 6,000 rads from therapeutic radiation is not provided. The concept of radiation dosage and cancer probability.

In radiation therapy, a high energy beam of ionizing radiation is used to destroy cancer cells, shrink tumors and alleviate cancer symptoms. Ionizing radiation can damage the DNA of healthy cells as well as cancer cells. Cancer can occur as a result of the DNA damage to the cell. A long-term health risk of exposure to ionizing radiation is the development of cancer.

Radiation-induced cancers may not develop for years or even decades after exposure. The probability of radiation-induced cancer is dependent on the dose received, the time elapsed since exposure, and the type of radiation.In the case of the given dose of 6,000 rads from therapeutic radiation, the probability of fatal cancers for stomach, bone marrow, and bone surface can be estimated using statistical data. For example, according to the National Cancer Institute, the lifetime risk of fatal cancer from exposure to 10,000 rads of ionizing radiation is about 25%. However, it is important to note that this risk is spread out over a lifetime and not immediate.

Step-by-step explanation:

if you grab 2 whole points, such as (-3,1) and (2,-3), you have to get the rise/run which in this case is -4/5. -4/5= -0.8

Answer:

-4/5

Step-by-step explanation:

So you probablly heard of y=mx+b. if you haven't, m is the slope.

You have to use rise over run to find slope so let's first find a point of the line.

(-3,1) is a point!

Since this is a negative line, the slope is going to be negative.

You have to go down 4 times and to the right 5 times for your next point. (2,-3)

So the slope is -4/5

And for slope intercept form it's in y= -4/5x + b (b = y-intercept)

one cyclist travels faster than the other. Therefore, the rate of the faster cyclist is (distance between towns) / (2 * hours) and the rate of the slower cyclist is also (distance between towns) / (2 * hours).

Let x = the rate of the faster cyclist, and y = the rate of the slower cyclist.

We can set up the equation:

x + y = (distance between towns) / (time they met)

x + y = (distance between towns) / (hours)

We can solve for x and y:

x = (distance between towns) / (2 * hours)

y = (distance between towns) / (2 * hours)

Therefore, the rate of the faster cyclist is (distance between towns) / (2 * hours) and the rate of the slower cyclist is also (distance between towns) / (2 * hours).

f(-3)=9-5

f(-3)=4

Answer:

f(-3) = 4

Step-by-step explanation:

f(x) = x² - 5

f(x) is a function with input x, meaning it is an expression which has terms involving x;

x is a variable and can be considered a space holder;

f(-3) is the function with input -3, this simply means replacing the space holder, i.e. x, with -3;

f(-3) = (-3)² - 5

f(-3) = 9 - 5

Among the options provided, a p-value of "p<.01" indicates a very significant correlation.. So, correct option is B.

A correlation coefficient measures the strength and direction of the relationship between two variables. The p-value associated with the correlation coefficient indicates the statistical significance of that relationship.

The p-value represents the probability of observing the correlation coefficient (or a more extreme value) under the assumption that there is no true correlation in the population.

In statistical hypothesis testing, a smaller p-value indicates stronger evidence against the null hypothesis, suggesting a more significant relationship between the variables.

Among the options provided, a p-value of "p<.01" indicates a very significant correlation. This means that the probability of observing the correlation coefficient (or a more extreme value) under the assumption of no correlation is less than 0.01, or 1%.

In other words, there is strong evidence to suggest that the observed correlation is not due to random chance and is likely a true relationship between the variables.

On the other hand, options such as "p=.05" and "p<.50" indicate less significant correlations, where the probability of observing the correlation coefficient under the null hypothesis is higher. Therefore, the answer that indicates a very significant correlation is "b) p<.01".

The equation of the total cost for the cover charge and drinks in point-slope form is y = 6x + 5.

The point-slope form of a linear equation is given by -

 \(y - y_1 = m(x- x_1)\)

where m is the slope and \((x_1, y_1)\) is a point on the line.

Here, the total cost for the cover charge and drinks can be represented by the equation y = mx + b, where y is the total cost, x is the number of drinks, m is the cost per drink, and b is the cost of the cover charge.

We know that the cover charge is $5 and drinks are $6 each, so, we can find the slope (m) of the equation by using the cost per drink which is m = 6.

We can also find the point \((x_1, y_1)\) by using the cover charge cost which is (0,5).

Therefore, the equation in point-slope form of the total cost for the cover charge and drinks will be -

y - 5 = 6(x-0)

y - 5 = 6x

y = 6x + 5

Where x is the number of drinks and y is the total cost i.e. cover charge + drinks.
