Answer:

  1a.  x = 0.08; y = 0.03; z = 0.17

  1b.  P(B) = 0.25

Step-by-step explanation:

Given a Venn diagram with some numbers filled in, you want to find the missing numbers given that the probability of at least one is 0.92, and of exactly one is 0.70.

The missing values are found by understanding the given information and what that means in relation to the diagram.

The total area enclosed by the circles is the probability of "at least one." The total probability represented by the entire diagram is 1, so that means ...

  x = 1 - 0.92 = 0.08 . . . . . . . area not in any circle

It also means that ...

  0.26 +0.05 +y +z +0.41 = 0.92 . . . . . . . area enclosed by circles

  y + z = 0.20 . . . . . . . . . . . . . . . . . subtract 0.72

The probability of exactly one is the sum of areas inside exactly one circle:

  0.26 +y +0.41 = 0.70

  y = 0.03

Using this with the above equation in y and z, we find ...

  z = 0.20 -y = 0.17

The area inside circle B is ...

  0.05 +y +z = 0.05 +0.20 = 0.25

The probability a contributor sponsors Bandicoots Unbanned is 0.25.

Henry's trumpet which is made of an alloy brass contains 9.6 ounces of zinc.

Brass is an alloy created using 80% copper and 20% zinc, which means that for every 100% of the alloy, 80% is copper and 20% is zinc.

If henry's trumpet contains 48 ounces of copper, we can use the proportion of copper and zinc in the alloy to find the number of ounces of zinc.

First, we can convert the percentage of zinc to a decimal by dividing by 100: 20% = 0.20

Next, we can set up an equation using the proportion of zinc in the alloy to the number of ounces of zinc in the trumpet:

0.20 = x/48 ounces of zinc

To solve for x, we can multiply both sides of the equation by 48:

0.20 * 48 = x

x = 9.6 ounces of zinc

So, Henry's trumpet contains 9.6 ounces of zinc.

The common difference is 4. To find it, you subtract the first two terms (5 and 9) to get 4. You can then use this answer to find the common difference in the sequence by subtracting each consecutive term. For example, 9-5=4, then 13-9=4, and so on.

The common difference is an important part of any arithmetic sequence. It is the number that is added to each term in the sequence to generate the next term. For example, the first two terms of the sequence are 5 and 9. The common difference of 4 is added to the first term (5) to get the second term (9). The common difference is then added to the second term (9) to get the third term (13), and so on. This is how the sequence is generated.  

The common difference is an important tool for analyzing the behavior of an arithmetic sequence. Knowing a common difference allows you to determine the nth term of the sequence, as well as the sum of the first n terms. It also helps you to identify patterns in the sequence and make predictions about future terms. Knowing a common difference is an essential part of analyzing arithmetic sequences.

Step-by-step explanation:

The measure of the angles of a triangle are 50°, 60°, 70°. The triangle is acute-angle triangle.

What is an acute angle?

An acute angle is one that is less than 90 degrees in length. This is a smaller angle than the right angle (which is equal to 90 degrees).

Given that the measure of the angles of a triangle are x, x+10, and x+20.

The sum of the interior angles of a triangle is 180°.

According to the question,

x+x+10+x+20 = 180°

3x + 30 = 180°

3x = 150°

Divide both sides by 3:

x = 50°.

Putting x = 50° in x, x+10, and x+20.

x =50° , x+10 = 60°, and x+20 =70°.

All angles of the triangle is 90°. Thus the triangle is an acute angle triangle.

if you used the same experimental design, but instead used an endotherm, you would expect to see a difference in the organism's ability to regulate its body temperature

If the same experimental design was used but with an endotherm (an organism that generates heat internally) instead of an ectotherm (an organism that relies on external sources of heat), I would expect to see a difference in the organism's ability to regulate its body temperature. Endotherms have a higher metabolic rate and are able to generate heat internally, whereas ectotherms rely on external sources of heat to regulate their body temperature. This means that endotherms would be less affected by changes in external temperature and would be able to maintain a more stable body temperature. Additionally, endotherms would likely have a higher tolerance for cold temperatures. I came to this conclusion because endotherms have internal heat regulation mechanisms that allow them to maintain a stable body temperature, whereas ectotherms do not.

What do you mean by melting point?

melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached.

The melting point of a liquid is the temperature at which the liquid transforms from a solid to a liquid under atmospheric pressure. This is the location where the liquid and solid phases are equally present. The substance's melting point varies with pressure as well and is reported at standard pressure.

As the melting point is 0 °C.

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

Functions were originally the idealization of how a varying quantity depends on another quantity. For example, the position of a planet is a function of time. Historically, the concept was elaborated with the infinitesimal calculus at the end of the 17th century, and, until the 19th century, the functions that were considered were differentiable (that is, they had a high degree of regularity). The concept of a function was formalized at the end of the 19th century in terms of set theory, and this greatly enlarged the domains of application of the concept.

The probability that a randomly selected customer likes hot or iced coffee is 0.83.

What is probability?

To find the probability that a randomly selected customer likes hot or iced coffee, we need to add the probability of liking hot coffee and the probability of liking iced coffee, while subtracting the probability of liking both (since we don't want to count those customers twice).

So, P(H or I) = P(H) + P(I) - P(H and I)

We are given that P(H) = 0.75, P(I) = 0.30, and P(H and I) = 0.22 (from the venn diagram).

Therefore, P(H or I) = 0.75 + 0.30 - 0.22 = 0.83

There is a 1/2 probability that both spinners will produce an odd number.

The probability is equal to the variety of possible outcomes.

The total number of outcomes that could occur.

For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2. (a head or tail). P(heads) = 12 is what we write.

So, assume that:

Both the spinners have 1 positive number and 1 odd number.

Probability formula:

P(E) = Favourable events/Total events

Now, calculate as follows:

P(E) = Favourable events/Total events

P(E) = 2/4

The ticket prices that would allow the theater to make $600 in revenue are $120 and $13.4.

In order for the theater to make $0 in revenue, the ticket price would have to be $4. This can be determined by setting the revenue functions equal to 0 and solving for p.

For p (120p - 4p) = 0

120p - 4p = 0

4p = 120

p = $30

For 120p - 4p2 = 0

Answer:

To answer this question, we need to use the properties of a normal distribution. So, the answer is b. 10,200

Step-by-step explanation:

The mean and standard deviation serve as the defining characteristics of a normal distribution, a form of probability distribution. The average tire lifespan in this situation is 50,000 miles, with a standard variation of 5,000 miles.

The number of tires that should last between 45,000 and 55,000 miles, or the region under the normal distribution curve between these two figures, is what we're looking for. The conventional normal table or a calculator using the inverse cumulative probability function can be used to find this region.

We can standardize the values by using the standard normal table, which is (X-mean)/standard deviation.

(45,000-50,000) / 5,000 = -1

(55,000-50,000) / 5,000 = 1

The area between -1 and 1 standard deviation from the mean is about 0.6826, which is the proportion of the tires that are expected to last between 45,000 and 55,000 miles.

To find the number of tires, we can multiply the proportion by the sample size (15,000)

0.6826 * 15,000 = 10,200

So, the answer is b. 10,200
