After computing a confidence interval, the user believes the results are meaningless because the width of the interval is too large, the best recommendation is c. Increase the sample size.

A confidence interval is a range of estimates for an unknown parameter in frequentist statistics. A confidence interval is calculated at a specific confidence level; the 95% confidence level is the most commonly used, but other levels, such as 90% or 99%, are also used.

Confidence intervals are used by statisticians to quantify uncertainty in a sample variable. A researcher, for example, may randomly select different samples from the same population and compute a confidence interval for each sample to determine how well it may represent the true value of the population variable. The resulting datasets are all unique, with some intervals containing the true population parameter and others not.

In this case, the sample size should be increased when the results are meaningless because the width of the interval is too large.

Since the provided equation is inconsistent, it cannot intersect.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

Here,

we can see that the second set of equation,

4x+2y=12

20x+10y=30

4/20=2/10≠12/30

1/5=1/5≠2/5

The given equation is inconsistent so it does not intersect.

Answer:

\(x=49.16^{\circ}\)

Step-by-step explanation:

We need to find the value of x in the given figure.

It is a right angled triangle, in which base is 19, height is 22.

We can use trigonometry to find x.

We know that,

\(\tan\theta=\dfrac{P}{B}\)

Where

P is perpendicular and B is base

So,

\(\tan x=\dfrac{22}{19}\\\\x=\tan^{-1}(1.157)\\\\x=49.16^{\circ}\)

So, the value of x is equal to \(49.16^{\circ}\).

Answer:

linda will get 35 candies

Answer:

Linda gets 33 candies

Step-by-step explanation:

Let's call Linda's number of sweets x and make an equation for the total number of candies:

70 = 4+ x + x

Then simplify it:

70 = 4 + 2x

We then solve for x ( which is the number of candies Linda gets ):

70 - 4 = 4 + 2x  - 4

66 = 2x

66 ÷ 2 = 2x ÷ 2

33 candies = x ( amount Linda gets )

Answer:

Child's ticket is $14.   [14, without the symbol]

Senior ticket is $8.     [8, without the symbol]

(WHAT???)

Step-by-step explanation:

Let S and C stand for the numbers of Senior and Child tickets sold.

We can write equations for both days:

Day 1:   3S + 1C = 38  [sold 3 senior citizen tickets and 1 child ticket for a total of $38]

Day 2:  3S + 2C = 52  [$52 on the second day by selling 3 senior citizen tickets and 2 child tickets]

Since both equations has a "3S" term, we can easily subtract one from the other:

3S + 1C = 38

-3S - 2C = -52

        - C = -14

C = 14  The price of a children's ticket is $14.

Use C = 14 in either equation to find S:

3S + 1C = 38

3S + 14 = 38

3S          = 24

S = 8  The price of a senior ticket is $8.

0.0166 correct to two significant figures is 0.016.

To write 0.0166 to two significant figures, we need to look at the first two significant digits of the number, which are 1 and 6.

Since the digit after 6 is less than 5, we round down the last significant digit (6) to get:

0.016

Therefore, 0.0166 correct to two significant figures is 0.016.

Answer:

4. We start with the base case of \(5^0 = 1\) and recursively generate the next element in the set by multiplying the previous element by \(5\).

5. if a divides \(b\) and \(b\) divides \(a\), either a equals \(b\) or \(a\) equals negative \(b\).

4. The recursive definition of the set of positive integer powers of 5 can be expressed as follows:

Base case: \(5^0 = 1\) is in the set.

Recursive step: If n is in the set, then \(5^(n+1)\) is also in the set.

Using this definition, we start with the base case of \(5^0 = 1\)and recursively generate the next element in the set by multiplying the previous element by \(5\).

5. To prove that if a divides \(b\) and \(b\)divides \(a\), then a equals \(b\) or \(a\) equals negative \(b\), we can use the definition of divisibility.

Assume that \(a\) divides \(b\), denoted as \(a | b\) , and \(b\) divides \(a\), denoted as \(b | a.\)

By definition, if a divides b, there exists an integer k such that b = ak.

Similarly, if \(b\) divides \(a\), there exists an integer m such that \(a = bm.\)

Substituting the expression for\(b\) in terms of \(a\), we have \(bm = ak.\)

Dividing both sides by b (since b is nonzero), we get m = a/b.

Since \(m\) is an integer, \(a/b\) must be an integer, which means \(a\) is divisible by \(b\).

If \(a/b\)  is an integer, it implies that \(b/a\)is also an integer, which means \(b\) is divisible by \(a\).

Therefore, if \(a\) divides \(b\) and \(b\) divides \(a\), it follows that \(a/b\) and \(b/a\) are both integers.

If \(a/b = m\) and \(b/a = k\), then we have \(a = bm\) and\(b = ak.\)

\(If m = k = 1, then $a = b.\)

\(If m = k = -1, then a = -b.\)

Therefore, if \(a\) divides \(b\) and \(b\) divides \(a\), either \(a\) equals \(b\) or \(a\) equals negative \(b\).

The marginal profit is a constant value of $27 per unit produced.

First, let's establish the revenue function. The revenue (R) is the product of the number of units sold (x) and the price per unit ($47). So, R(x) = 47x.

Next, let's find the profit function (P). Profit is the difference between revenue and cost: P(x) = R(x) - C(x). Plugging in the given functions, we get P(x) = (47x) - (160 + 20x + 6).

Now, to find the marginal profit P'(x), we need to take the derivative of the profit function with respect to x:

P'(x) = d/dx[(47x) - (160 + 20x + 6)]
P'(x) = 47 - 20

Therefore, the marginal profit P'(x) = 27. This means that, for each additional unit produced, the profit increases by $27.
