Answer:

5

Step-by-step explanation:

This is quite some trial and error question.

Based on the question, the numbers we can use are 1,3,5,7 and 9.

We will start with the middle digit first.

Since the question has stated it is 3 times the last digit, the number has to be in multiples of 3.

So we are left with: 3 and 9.

Then, the question also states the middle digit is 4 more than the first digit. See, its a digit, so the value cannot be less than 1 (odd numbers only and no negative values), so if we subtract 4 to the middle digit to find the first, it should still be a Positive Single numerical value.

3 - 4 = -1

9 - 4 = 5

Therefore, this middle digit is = 9.

Since we know the middle digit = 9

The first digit will be 9 - 4 = 5

The whole value is now 593.

Given a random sample of 2,000 households are selected for telephone interviews in which 432 interviews are completed, 586 are refused by the respondent, 902 do not answer or are not at home and 80 are non-working numbers.

Total Number of sample, S =2000

Completed interview, C = 432

Refusal by the Respondent, R = 586

No answer/ not at home , N = 902.

Non - working Numbers, NW = 80.

From the above data, we got responses from completed interviews and refusals by respondents.

so responded number (RN) is

RN=C+R

RN= 432+ 586

RN= 1018.

The actual number of samples =Total samples - non-working samples Actual number of samples=2000-80

The actual number of samples=1920

And the response rate (RR) is

RR=1018÷1920

RR=0.52021

Hence, the response rate from 2000 households which are selected for telephone interviews is 0.52021.

Answer:

16/25 or 64%

Step-by-step explanation:

There are 12 even numbers between 1 and 25: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24

There are 8 multiples of 3 between 1 and 25: 3, 6, 9, 12, 15, 18, 21, and 24

That makes your odds 20/25. But, you can't count numbers twice! So eliminate the repeats and you get:

2, 3, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, and 24

which is 16/25 numbers that satisfy being an even number, a multiple of 3, or both

Answer:

A. The color of fire when different metals are burned.

Explanation:

Qualitative data is data that relates to a quality or characteristic of an object, and does not include any numbers.

example: colour, taste, survey answers

Quantitative data, on the other hand, relates to measurements and counting of variables, and uses numbers to convey value.

example: height of a person, number of coins

The probability that a simple random sample of 45 unemployed individuals will provide is 0.7372

Here, μ = 17.5, σ = 0.8944, x1 = 16.5 and x2 = 18.5.

We need to compute P(16.5<= X <= 18.5).

The corresponding z-value is calculated using Central Limit Theorem.

z = (x - μ)/σ

z1 ⇒ (16.5 - 17.5)/0.8944 = -1.12

z2 ⇒ (18.5 - 17.5)/0.8944 = 1.12

Therefore, we get

P(16.5 <= X <= 18.5) = P((18.5 - 17.5)/0.8944) <= z <= (18.5 - 17.5)/0.8944)

⇒ P(-1.12 <= z <= 1.12) = P(z <= 1.12) - P(z <= -1.12)

⇒ 0.8686 - 0.1314 = 0.7372

The principal limit theorem states that if you have a population with imply μ and trendy deviation σ and take sufficiently huge random samples from the populace with alternative, then the distribution of the pattern method may be about usually distributed.

The relevant limit theorem (CLT) states that the distribution of pattern manner approximates a normal distribution as the pattern size gets larger, regardless of the population's distribution. sample sizes identical to or extra than 30 are often considered enough for the CLT to preserve.

Six less than the quotient of two and a number "W"

Let's take this step-by-step. First, change the written-out numbers to numerals:

6 less than the quotient of 2 and a number "W"

Next, combine the smallest part. In this case, it would be:

the quotient of 2 and a number "W"

Here, you are finding the quotient of a specific part: 2 and W. When we have specific sections like this in math, we put parentheses around them, like this:

6 less than the quotient of (2 and a number "W")

Now we need to remember what a "quotient" is. This means that there is division between the two numbers mentioned - in this case, 2 and the number W. But which is being divided into which? The number 2 comes first, so we think of 2 as being the first number used. Therefore, we are looking at:

6 less than (2 divided by W)

Division problems are exactly the same as fractions. For example, 3 divided by 1 is the same as 3 ÷ 1, which is also the same as 3/1 (which equals 3). In our case, 2 divided by W is the same as 2/W (your teacher might want this written as 2 ÷ W, but they mean the same thing). Now, we can write the equation as:

6 less than (2/W)

Which can also be written as:

6 less than 2 ÷ W

To finish this up, let's take a step back for a moment Imagine you have 10 jelly beans, and you eat 7 of them. You now have 7 less than 10, or 3 jelly beans. This can also be written as 10-7 = 3.

In our example, we have 6 less than (2/W). If we use the jelly bean equation we found as a starting point, we can change the 7 to 6 and the 10 to (2/W). Then, we get this:

(2/W) - 6

Which can also be written as:

2 ÷ W - 6

And that's your answer! Both of those mean the same thing so they're both correct. Your teacher might prefer you write it one way or the other, though. If this is the case, make sure to choose the solution that best fits your teacher's request.

The length of each side of the equilateral triangle is 5x³ + 11x⁵

From the question, we are to determine the length of each side of the equilateral triangle.

An equilateral triangle has its sides equal to each other.

If the length of a side of an equilateral triangle is c,

Then, the perimeter, P, of the triangle is

P = 3c

From the given information,

P = 15x³ + 33x⁵

∴ 3c = 15x³ + 33x⁵

c = (15x³ + 33x⁵) / 3  

c = 3(5x³ + 11x⁵) / 3

c = 5x³ + 11x⁵
