Answer:

pre image point A (8,0)

Step-by-step explanation:

I guess thats the answer

A = (x, y)

After a translation right 2 units and down 1 unit is the point B (10, -1)

A = (x + 2, y - 1)

B = (10, -1)

A = B

x + 2, y - 1 = 10, -1

x, y = 10 - 2, -1 + 1

x, y = 8, 0

(x, y) = (8, 0)

The coordinates of pre-image point A is (8, 0)

Answer:

x = 122°

Step-by-step explanation:

There is remote angle( non- adjecent angle) and their sum equal to the exterior angle .

Exterior angle is an angle formed from one side of the polygone and the extended side so

<A and <B are remot angle and <BCD is exterior angle .

And we write the equetion as

<A + <B = <BCD

58° + 64° = x°

122° = X°

so the exterior angle ( x ) measures 122° .

It means all the points on a horizontal line have  different x-coordinates but same y- coordinates.

Looking at the answer choices we can only see the pairs (-6, 9) and (22, 9) follow this rule. Hence A is the correct choice.

Answer:

(-6, 9) and (22, 9)

Step-by-step explanation:

For a point (x, y):

A horizontal line is represented by the equation y = a, where (0, a) is the y-intercept of the line.

Each point on a horizontal line has the same y-value.

Therefore, the only ordered pair that has the same y-value, and therefore lies on a horizontal line is:

The equation of the horizontal line that contains the two ordered pairs is y=9.

Answer:

Cost of 1 beef= $7.5

Cost of 1 bacon= $6

Step-by-step explanation:

Ok so first of organize everything:

We know she buys 6 pounds ->beef and 3 pounds ->bacon

First we need to set up an equation of how much 1 beef costs and 1 bacon costs:

Let’s say f=cost of 1 beef and b=cost of 1 bacon

Now lets make the equation:

6f+3b=63. (She buys 6 portions of beef and 3 bacon and her total comes out to 63)

Now their is another condition that the cost of one bacon is -$1.50 per pound than beef.

So we can say b=f-1.50

Do you notice anything similar? The b has a value now and so we can replace the b in our first equation with the b of the 2nd (b=b)

So hence,

6f+3(f-1.50)=63

6f+3f-4.5=63

9f=67.5

F=7.5 (This is the cost for 1 pound of beef)

Now lets find out for bacon,. Now instead of doing this equation all over again just insert it into the b=f-1.5 you know make life easier for yourself:

B=7.5-1.5

B=6

Cost of 1 beef= $7.5

Cost of 1 bacon= $6

Out of the three given options, option a) is the most appropriate definition of an experiment in the context of probability.

The term "experiment" in the context of probability refers to a process or activity that involves observing or measuring an outcome that is subject to chance or uncertainty. The outcome of an experiment is not necessarily predictable with certainty, and it may depend on various factors such as the conditions under which the experiment is conducted and the randomness inherent in the process.

Out of the three given options, option a) is the most appropriate definition of an experiment in the context of probability. An experiment is essentially a process that leads to one of several possible outcomes, and the probability of each outcome can be calculated or estimated based on the underlying assumptions and factors involved. Examples of experiments in probability include rolling a die, tossing a coin, drawing a card from a deck, or conducting a clinical trial to test a new drug.

Option b) is not an appropriate definition of an experiment because it suggests that the outcome can be predicted with certainty based on mathematical analysis, which is not always the case in experiments involving chance or uncertainty.

Option c) is also not an appropriate definition of an experiment because it suggests that an experiment is conducted to confirm a hypothesis, which may or may not be true. While experiments can be used to test hypotheses and provide evidence to support or refute them, the primary goal of an experiment in the context of probability is to observe or measure the outcome and calculate the probability of each possible outcome.

The probability that at most two emergency flares will light can be calculated using the binomial probability. The answer is option b. 0.057.

The binomial formula is used to calculate the probability of a specific number of successes (in this case, the number of flares that light) in a fixed number of independent trials (the number of flares carried). It is given by the formula:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

Where:

P(X = k) is the probability of getting exactly k successes,

C(n, k) is the number of combinations of n items taken k at a time,

p is the probability of success in a single trial, and

n is the number of trials.

In this scenario, n = 5 and p = 0.80. We need to calculate the probability of at most two flares lighting, which includes the probabilities of zero, one, and two flares lighting. Thus, we can use the formula to calculate these individual probabilities and sum them up:

P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)

P(X = 0) = C(5, 0) * (0.80)^0 * (1 - 0.80)^(5 - 0)

        = 1 * 1 * 0.2^5

        = 0.00032

P(X = 1) = C(5, 1) * (0.80)^1 * (1 - 0.80)^(5 - 1)

        = 5 * 0.80 * 0.2^4

        = 0.0256

P(X = 2) = C(5, 2) * (0.80)^2 * (1 - 0.80)^(5 - 2)

        = 10 * 0.80^2 * 0.2^3

        = 0.2048

Summing up these individual probabilities, we get:

P(X ≤ 2) = 0.00032 + 0.0256 + 0.2048

        = 0.23072

Hence, the probability that at most two flares will light is approximately 0.23072, which is equivalent to 0.057 when rounded to three decimal places.

This is how much she will pay for the food plus tax.

Now, multiply 42 by 1.2.

42×1.2=50.40

This is how much she will pay for the food, tax, and tip.

Lana will pay a total of $50.40.

T symbol in statistics means Test statistic for t-test ( t-score )

What is  t-statistic ?

The t-statistic in statistics measures how far an estimated value of a parameter deviates from its hypothesised value in relation to its standard error.

T symbol in statistics mean Test statistic for t-test (  t-score )

Through the Student's t-test, it is utilised for testing hypotheses. To decide whether to accept or reject the null hypothesis in a t-test, the t-statistic is used.

It is quite comparable to the z-score, but when the sample size is small or the population standard deviation is unknown, the t-statistic is employed instead.

For instance, if the population standard deviation is unknown, the population mean can be estimated using the t-statistic from a sampling distribution of sample means.

Answer: We can use the following formula for the union of two sets:

n(A U B) = n(A) + n(B) - n(A ∩ B)

where n(A ∩ B) is the number of elements in the intersection of A and B.

Substituting the given values, we get:

n(A U B) = n(A) + n(B) - n(A ∩ B)

n(A U B) = 25 + 18 - 7

n(A U B) = 36

Therefore, the value of n(A U B) is 36.
