The cost of 24 bottles of water is $6. How much does it cost for 10 bottles of water?

Beth's statement is incorrect.

The main answer: No.

Using the z-distribution instead of the t-distribution when constructing a confidence interval for a mean with unknown variance can lead to an incorrect interval width. The t-distribution takes into account the sample size, which is particularly important when the sample size is small. By using the z-distribution, which assumes a large sample size or known variance, the resulting interval may be narrower than necessary. This means that the interval might not capture the true population mean with the desired level of confidence.

4x=16

divide both sides by 4 to get 4

Answer:

\(\displaystyle (3, 4) \cup (4, 13)\)

Step-by-step explanation:

We are given the set:

\(\displaystyle \left\{ x| 3 < x < 13 \text{ and } x \neq 4\right\}\)

And we want to express this in interval notation.

In words, this reads: all values of x between 3 and 13 and x does not equal 4.

Hence:

\(\displaystyle (3, 4) \cup (4, 13)\)

We use parentheses as we do not include the values of 3 and 13 inside our interval. Likewise, since x cannot equal 4, we skip four, but use the union symbol to connect the two intervals.

\(\\ \sf\longmapsto \left\{x|3<x<13,x\neq 4\right\}\)

The solution is

\(\\ \sf\longmapsto (3,4)\cup (4,13)\)

Now Find all elements

Step-by-step explanation:

The interval estimate for an average value of y in a linear regression model is narrower compared to the confidence interval estimate for a particular value of y. Therefore, the correct answer is (a) narrower.

In a linear regression model, the confidence interval estimate for a particular value of y represents the range of values within which we expect the true value of y to fall with a certain level of confidence. This interval is based on the variability of the data and the uncertainty in the estimation.

On the other hand, the interval estimate for an average value of y considers the average of multiple y values. Since the average is based on a larger sample size, it reduces the variability and uncertainty compared to estimating a single value. As a result, the interval estimate for the average value of y is narrower.

The larger sample size used to estimate the average value of y allows for a more precise estimate, resulting in a narrower interval.

The probability of rain tomorrow is the same regardless of whether it has rained in the past two days or not. Therefore, we cannot use the given information to make a prediction about the weather tomorrow.

In example 4.4, we are given a situation where it has not rained in the past two days. The question asks for the probability of rain tomorrow. This type of question falls under the category of conditional probability. In conditional probability, we find the probability of an event given that another event has already occurred.
To solve this problem, we can use Bayes' theorem. Bayes' theorem states that the probability of an event A given that event B has occurred is equal to the probability of event B given that event A has occurred multiplied by the probability of event A divided by the probability of event B.
Let us define the events in this problem as follows:
A = It will rain tomorrow
B = It has not rained in the past two days
Using the given information, we know that P(B) = 0.75 (since there are four possible outcomes: rain yesterday, rain day before yesterday, rain both days, no rain both days, and we are given that the latter has occurred). We need to find P(A|B).
To find P(A|B), we need to find P(B|A), which is the probability that it has not rained in the past two days given that it will rain tomorrow. Since we do not have any information about the relationship between these two events, we can assume that they are independent.
Therefore, P(B|A) = P(B) = 0.75
Now, we can use Bayes' theorem to find P(A|B):
P(A|B) = P(B|A) * P(A) / P(B)
P(A|B) = 0.75 * P(A) / 0.75
P(A|B) = P(A)
This means that the probability of rain tomorrow is the same regardless of whether it has rained in the past two days or not. Therefore, we cannot use the given information to make a prediction about the weather tomorrow.

We have been given a circle. We are asked to find the measure of arc MN.

We know that the measure of all arcs in a circle is equal to 360 degrees. SO we can set an equation as:

\(\widehat{MN}+\widehat{NO}+\widehat{OL}+\widehat{LM}=360^{\circ}\)

Upon substituting our given values, we will get:

\(\widehat{MN}+110^{\circ}+130^{\circ}+54^{\circ}=360^{\circ}\)

\(\widehat{MN}+294^{\circ}=360^{\circ}\)

\(\widehat{MN}+294^{\circ}-294^{\circ}=360^{\circ}-294^{\circ}\)

\(\widehat{MN}=66^{\circ}\)

Therefore, measure of arc MN is 66 degrees and option 'c' is the correct choice.

Supplementary angles are angles that add up to 180°. Angle 6 is a right angle, so it's worth 90°. This means that the other angle(s) have to be 90° as well.

As you can see, the other angle with 90° is angle 3, thus, making it the correct answer.

Answer:

maximum length is 7 cm.

minimum length is 3 cm.

Step-by-step explanation:

In a triangle, the sum of the lengths of two sides is larger than the value of the other side.(Here, the last side would be the longest side)

3+5=8 so the biggest whole number less than 8 is 7.

So, the maximum whole number side length is 7 cm.

Also, the difference between the lengths of two sides is less than the length of the other side.

5-3=2 so the smallest whole number greater than 2 is 3.

So, the minimum whole number side length is 3 cm.

Answer:

(x + 6)(x + 7)

Step-by-step explanation:

To factor the trinomial x^2 + 13x + 42, we need to find two numbers that multiply to 42 and add up to 13.

One way to do this is to list all the pairs of factors of 42 and see which pair adds up to 13:

1, 42 -> 1 + 42 = 43

2, 21 -> 2 + 21 = 23

3, 14 -> 3 + 14 = 17

6, 7 -> 6 + 7 = 13

So the pair of factors that we want is 6 and 7. We can use these numbers to rewrite the middle term of the trinomial:

x^2 + 13x + 42 = x^2 + 6x + 7x + 42

Next, we can group the first two terms and the last two terms:

x^2 + 6x + 7x + 42 = (x^2 + 6x) + (7x + 42)

Now, we can factor out the greatest common factor from each group:

x(x + 6) + 7(x + 6)

Notice that we have a common factor of (x + 6) in both terms. We can factor this out:

(x + 6)(x + 7)

Answer: p=8,−1

Step-by-step explanation:

p^2-7p--8=0

(p-8)(p+1)=0

p=8,−1

Answer:

The solution set of p^2– 7p = 8 is {-1, 8}

Step-by-step explanation:

Rewrite p^2– 7p = 8 as p^2– 7p - 8 = 0 (standard quadratic form).

Factoring is relatively straightforward here:  (p - 8)(p + 1) = 0

Here we have a zero product equal to zero.  Thus, we can create two equations based on these two factors:  (p - 8) = 0 and (p +1) = 0.  The first equation yields p = 8 and the second p = -1.

The solution set of p^2– 7p = 8 is {-1, 8}

We consider the future value of Michael's investments over the 10 years and then apply the formula for the present value of a perpetuity. With an effective annual interest rate of 5%, the value of K is $71.80.

In the first paragraph, we need to calculate the future value of Michael's investments over the 10-year period. Since he invests $1,000 at the beginning of each year, we can use the formula for the future value of an annuity. Considering an effective annual interest rate of 5%, we have:

\(FV = P * [(1 + r)^n - 1] / r\)

Where FV is the future value, P is the annual payment, r is the interest rate, and n is the number of years. Plugging in the values, we get:

FV = $1,000 * [\((1 + 0.05)^{10}\) - 1] / 0.05

  ≈ $12,578.86

Now, we can calculate the value of K, the annual payment from the perpetuity. The formula for the present value of a perpetuity is:

PV = K / r

Where PV is the present value and r is the interest rate. Rearranging the formula, we can solve for K:

K = PV * r

Since Michael uses the fund to buy the perpetuity at the end of year 10, we need to calculate the present value of the future value obtained from his investments. Applying the formula with an interest rate of 5%, we have:

PV = $12,578.86 / \((1 + 0.05)^{10}\)

  ≈ $7,594.97

Finally, plugging the values into the equation for K, we get:

K = $7,594.97 * 0.05

  ≈ $379.75

Therefore, K, the annual payment received from the perpetuity, is approximately $379.75, rounded to the nearest cent.

Answer:

  39√2 feet

Step-by-step explanation:

You want the length of the diagonal of a square that is 39 feet on a side.

The Pythagorean theorem can be used to find the length of the diagonal. It tells you the length of the hypotenuse of a right triangle with legs 39 ft will be ...

  d² = 39² +39²

  d² = 39²(1 +1) = 39²·2

  d = √(39²·2) = 39√2

The length of the diagonal is 39√2 feet.

Additional comment

As you can tell from this answer, the length of the diagonal of any square is √2 times the length one side. Knowing this, you can write down the answer without any further effort.
