If there is a 25% chance that a customer who purchases milk will also purchase bread. the probability of a milk purchase is 70%.  the probability that a customer will purchase bread given that they purchase milk is 36%.

How to find the probability?

Using this formula to find the probability that a customer will purchase bread given that they purchase milk

P(B | M) = P(M / B) / P(M)

Let plug in the formula

P(B | M) = 0.25 / 0.70

P(B | M) = 0.3571 ×100

P(B | M) = 36% (approximately)

Therefore the probability is 36%.

Answer:

$16.32

Step-by-step explanation:

First you need to find how much each thing is going to cost.

So for 32 glue sticks, it will cost $44.80 because you multiply 32 by 1.40.

Next you need to find the cost of thebox of crayons, which is $18.88 because you multiply 32 by 0.59.

Then you add those two totals together and you get 63.68.

Lastly you subtract that from 80 to see how much money Ms. Blankenship has  leftover which is $16.32.

The answer to the question is (i) the measurement of angles and distances in accordance with specific procedures.

A survey is a method used to gather information about a particular population or sample group. It involves collecting data through various means such as questionnaires, interviews, and observations. The purpose of a survey is to obtain information about a particular topic or issue that can be used for analysis, decision-making, or research purposes.

The items listed in options (ii), (iii), and (iv) all pertain to information that may be included in a land survey, which is a type of survey used to determine the boundaries, size, and characteristics of a piece of land. A professional measurement of a tract of land, the type of improvements best suited for the land, and the total area of the land with its mapped boundaries and elevation are all important pieces of information that may be gathered during a land survey.

On the other hand, the measurement of angles and distances in accordance with specific procedures is not typically part of a survey, as it is more closely related to a surveying technique known as triangulation. Triangulation is a method used to determine the location of a point by measuring angles and distances from fixed points. While similar in name, surveying and triangulation are distinct practices.

2z (2z + 5) - 3 (2z + 5)

(2z + 5)(2z - 3)

Answer:

(2z+5) (2z-3)

Step-by-step explanation:

First, multiply the first coefficient by the third.

4*-15=-60

Then find factors of -60 that add up to the middle term.

The factors are: -6 and 10-------> -6*10=-60 and -6+10=4 so -6 and 10 are the correct factors.

Break up the middle term with the factors that you got above. The new equation will be: 4\(z^{2}\)-6z+10z-15

Factor by grouping.

First, break the equation into two

(4\(z^{2}\)-6z) (10z-15)

Then, factor out the greatest number you can

2z(2z-3) 5(2z-3)

You are then left with a common binomial of 2z-3. COmbine the common binomial into 1 and combine the 2 numbers you factored out in the step above (2z and 5) The final equation will be this:

The probability that a randomly selected tire will have a life of at least 38,100 miles is 0.9115.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.

Let, the life expectancy of a particular brand of tire is normally distributed with a mean of 30,000 and a standard deviation of 6,000 miles.

So, μ = 30000, σ = 6000, x = 38100.

Therefore,

z  = (x - μ) / σ

   = (38100 - 30000) / 6000

   = 8100 / 6000

   = 81 / 60

z  = 1.35

Now,

P(X = 38100) = P(z = 1.35) = 0.9115

Hence, the probability that a randomly selected tire will have a life of at least 38,100 miles is 0.9115.

The standard matrix A of T, i.e., T(x)=Ax. Also,find T(x), where x=(2,-3) is T(x) = (-13, -11, 6, 8).

The standard matrix A of T can be found by using the formula A = [T(e1) T(e2)], where T(e1) and T(e2) are the images of the standard basis vectors e1 and e2 under the transformation T. In this case, T(e1) = (1, 2, 3, 4) and T(e2) = (5, 5, 0, 0), so the standard matrix A of T is:

A = [T(e1) T(e2)] = [(1, 2, 3, 4) (5, 5, 0, 0)] = [[1, 5], [2, 5], [3, 0], [4, 0]]

To find T(x), where x = (2, -3), we can use the formula T(x) = Ax. Substituting the values of A and x into this formula gives:

T(x) = Ax = [[1, 5], [2, 5], [3, 0], [4, 0]] * [(2), (-3)] = [(2*1 + (-3)*5), (2*2 + (-3)*5), (2*3 + (-3)*0), (2*4 + (-3)*0)] = [(-13), (-11), (6), (8)]

So the answer is T(x) = (-13, -11, 6, 8).

Different logs measure different physical properties of the formation that are related to porosity, and the relationship between the log measurement and porosity can be expressed through equations.

The different logs used to obtain porosity and their principles of measurement, quantities measured, and relation to porosity.
There are three main types of logs used to obtain porosity: neutron logs, density logs, and sonic logs.
Neutron logs: These logs measure the hydrogen content in a formation, which is directly related to porosity. The tool emits neutrons that interact with hydrogen atoms, and the resulting gamma rays are measured. The count rate decreases with increasing porosity. The neutron log can be expressed as:
Porosity = (neutron log reading - matrix reading) / (fluid reading - matrix reading)
Density logs: Density logs measure the bulk density of a formation, which can be related to porosity. The tool emits gamma rays that interact with the formation, and the scattered gamma rays are measured. The bulk density decreases with increasing porosity. The density log can be expressed as:
Porosity = (matrix density - bulk density) / (matrix density - fluid density)
Sonic logs: Sonic logs measure the travel time of sound waves through a formation, which can be related to porosity. The tool sends an acoustic wave and measures the time it takes to travel a specific distance. The travel time increases with increasing porosity. The sonic log can be expressed using Wyllie's time-average equation:
Porosity = (sonic log reading - matrix reading) / (fluid reading - matrix reading)
In summary, neutron logs measure hydrogen content, density logs measure bulk density, and sonic logs measure travel time of sound waves. These measurements can be used to calculate porosity using the respective equations provided.

The null and alternative hypothesis is H₀ : p = 0.30 and Hₐ : p ≠ 0.30 respectively.

A hypothesis is a theory put up to explain a phenomenon. A hypothesis must be testable according to the scientific method for it to be considered a scientific hypothesis.

Two alternatives being the same is the null hypothesis. The underlying assumption is that the observed difference is just the result of chance.

Hello! My Name is Galaxy and I'll be helping you today :D. I hope you are having a nice day!

So what we can do is first find the different between two input/outputs. To do that we can first compare them, then calculate for them, and create an equation.

Comparison

First, to figure out the problem, we have to look at its I/Os (Input/Output). We can pick the numbers (1,48) and (2,56).

Before we do it, lets find the difference.

When \(x\) is 1, \(y\) is 48.

When \(x\) is 2, \(y\) is 56,

After we look at it, we see that for everyone 1 Input we have, 8 gets added to the output.

Calculating

So, we know that the starting number is 48 and it builds up by 8 on that, so then the starting part of the equation would be:

\(o=48+...\)

(The Ellipsis over here does not mean that the number is continuing!)

We can expand on that since we know that it adds up by 8 per number we add, but to make that work, we have to subtract 8 from 48 so that once we get one, we will get a viable output.

After we do the modifications, we get a equation that looks good!

\(o=40+8i\)

I is for the Input

O is for the Output

Checking our Answer / Final Answer

Before we move on, we have to check if our answer is correct, lets try inputing the numbers into our function and seeing if it works!

\(48=40+1(8)\\48=48\)

The first one looks correct!

\(56=40+8(2)\\56=56\)

The second one looks correct as well.

\(64=20+(8)3\\64=64\)

This is also correct, we have now verified that this is a correct equation and that it indeed works.

Final Answer: \(o=40+8i\)
