Step-by-step explanation:

To find the common factors and the highest common factor (HCF) of 8y and 12y,

Factorizing 8y:

8y = 2 * 2 * 2 * y

Factorizing 12y:

12y = 2 * 2 * 3 * y

The common factors of 8y and 12y are 2 and y. The HCF, also known as the greatest common divisor (GCD), is the product of these common factors.

HCF of 8y and 12y = 2 * y = 2y

Therefore, the common factor is 2y, and the HCF of 8y and 12y is 2y.

The least number of seats the manger could order to 270 seats

The information that the the seats are sold only in groups of 10 will help to know that the order will be in a multiple of 10.

The manager wants to order 267 seats and this is not a multiple of 10 the nearest multiple of 10 is 270.

This is because, 260 will be short of want the manager want however ordering for 270 will be in excess with three seats.

Hence the manager will order 270 and heave 3 extra seats

18.6 m is the height of the building.

What is called cuboid?

For this, we are going to be using proportions to solve. But firstly, we have to convert cm to m. For this, I'll be using dimensional analysis:

\(\frac{44 cm}{1} * \frac{0.1 cm}{1} = \frac{0.44}{1} = 0.44 m\)

\(\frac{59 cm}{1} * \frac{0.01 m}{1 cm} = \frac{0.59}{1} = 0.59 m\)

Now that we have everything in meters, we can put it into proportions. In this case, our proportion is \(\frac{x}{25} = \frac{0.44}{0.59}\)

                                            0.59 x = 11

Next, divide both sides by 0.59, and your answer will be x = 18.6 m, or D.

Step-by-step explanation:

but if the y intercept is 0 then it’ll show like: y= 3x which is equal to y=3x plus or minus 0

No, a piecewise function does not always have an x and y intercept.

A piecewise function is a function that is defined by multiple sub-functions, each of which applies to a certain interval of the main function's domain.

An x-intercept is the point where the function crosses the x-axis, and a y-intercept is the point where the function crosses the y-axis.

It is possible for a piecewise function to not have an x or y intercept if none of the sub-functions cross the x or y axis. For example, the piecewise function f(x) = {2x + 1 for x < 0, -2x + 1 for x > 0} does not have an x or y intercept because neither of the sub-functions cross the x or y axis.

In conclusion, a piecewise function does not always have an x and y intercept. It depends on the sub-functions that make up the piecewise function.

The probability of being dealt a 3, 4, 5, 6, 7, all in the same suit is approximately 0.0000031.

To calculate the probability of being dealt a 3, 4, 5, 6, 7, all in the same suit, we can use the following formula:

P = (number of favorable outcomes) / (total number of possible outcomes)

the order in which the cards are chosen does not matter, so we need to divide by the number of ways we can arrange 5 cards, which is 5! (5 factorial).

Therefore, the total number of possible outcomes is (52 * 51 * 50 * 49 * 48) / (5 * 4 * 3 * 2 * 1), which simplifies to 2,598,960.

Finally, we can calculate the probability of being dealt a 3, 4, 5, 6, 7, all in the same suit:

P = 8 / 2,598,960

P = 0.00000308 (rounded to seven decimal places)

- Span{v1, v2, v3, 0} is equal to the span of {v1, v2, v3}.
- Span{v1, v1-v2, v3} is equal to the span of {v1, v2, v3}.
- Span{v1, v2} is NOT equal to the span of {v1, v2, v3}.

Let's analyze each of the sets of vectors to determine if they are equal to the span of {v1, v2, v3}:
1. Span{v1, v2, v3, 0}:
This set is equal to the span of {v1, v2, v3} because adding the zero vector (0) does not affect the linear independence or the span of the other vectors.

A span is the set of all possible linear combinations of the vectors, and since the zero vector does not change the linear combinations, the span remains the same.
2. Span{v1, v1-v2, v3}:
This set is also equal to the span of {v1, v2, v3}.

The reason is that the vector (v1-v2) can be written as a linear combination of v1 and v2: (v1-v2) = 1*v1 + (-1)*v2.

Since all vectors in this set can be expressed as linear combinations of {v1, v2, v3}, the span remains the same.
3. Span{v1, v2}:
This set is NOT equal to the span of {v1, v2, v3} because it is missing the vector v3.

Since v1, v2, and v3 are linearly independent, removing one of them (v3 in this case) means that the set cannot span the same space as {v1, v2, v3}.

It has a lower dimension, and therefore, the span is different.

What is set theory?

Set theory is a branch of mathematical logic that studies sets, which are collections of objects. Sets are usually represented by listing their elements between curly braces, such as {1, 2, 3, 4, 5}, where each element is separated by a comma.

We can use the inclusion-exclusion principle to solve this problem. The principle states that:

|A ∪ B| = |A| + |B| - |A ∩ B|,

where A and B are sets, and |.| denotes the number of elements in a set.

In this problem, let A be the set of prisoners accused of felonies, and B be the set of prisoners accused of misdemeanors. We know that |A| = 130, |B| = 121, and |A ∪ B| = 190. We want to find |A ∩ B|, the number of prisoners accused of both a felony and a misdemeanor.

Using the inclusion-exclusion principle, we have:

|A ∪ B| = |A| + |B| - |A ∩ B|

190 = 130 + 121 - |A ∩ B|

|A ∩ B| = 130 + 121 - 190

|A ∩ B| = 61

Therefore, there were 61 prisoners accused of both a felony and a misdemeanor.

Answer:

the price for 10 balls is $8.00

Step-by-step explanation:

Given;

The total price function;

P = 0.80n + 5.50

Total price P = price of balls(variable cost) V+ entrance fee(fixed) F

So,

price of balls(variable cost) V(n) = 0.80n

entrance fee(fixed) F = 5.50

The price for 10 balls, not including the entrance fee is

V(n) = 0.80n

n = 10

Substituting the given values;

V(10) = 0.80(10) = $8.00

the price for 10 balls is $8.00

I am 95% confident that the true proportion of couples where the wife is taller than her husband is captured in the interval (.028, .071)

Step-by-step explanation:

Given

\(n = 400\)

\(x = 20\) --- taller wife

\(y = 380\) --- shorter wife

Required

Determine the 95% confidence interval of taller wives

First, calculate the proportion of taller wives

\(\hat p = \frac{x}{n}\)

\(\hat p = \frac{20}{400}\)

\(\hat p = 0.05\)

The z value for 95% confidence interval is:

\(z = 1.96\)

The confidence interval is calculated as:

\(CI = \hat p \± z \sqrt{\frac{\hat p (1 - \hat p)}{n}}\)

\(CI = 0.05 \± 1.96* \sqrt{\frac{0.05 (1 - 0.05)}{400}}\)

\(CI = 0.05 \± 1.96 * \sqrt{\frac{0.0475}{400}}\)

\(CI = 0.05 \± 1.96 * \sqrt{0.00011875}\)

\(CI = 0.05 \± 1.96 * 0.01090\)

\(CI = 0.05 \± 0.021364\)

This gives:

\(CI = (0.05 - 0.021364,0.05 + 0.021364)\)

\(CI = (0.028636,0.071364)\)
