Step-by-step explanation: The answer to a division problem is called the quotient. Let's look at an example of how we would use the word.

Divide the following

610 ÷ 5 = 122

*I have attached the work for this in the image provided.*

Since 122 is the answer for the division problem, we call it the quotient.

The answer to a division problem is called a ''quotient''. The number that is being divided is called the ''dividend'' and the number that is dividing the dividend is called the ''divisor''.

An automatic filling machine is used to fill bottles with liquid detergent. A random sample of 18 bottles results in a sample st

Nookie1986 [14]

Answer:

$\frac{(17)(0.038)^2}{32.64} \leq \sigma^2 \leq \frac{(17)(0.038)^2}{6.66}$

$0.0008 \leq \sigma^2 \leq 0.0037$

Step-by-step explanation:

Data given and notation

s=0.038 represent the sample standard deviation

$\bar x$ represent the sample mean

n=18 the sample size

Confidence=97.5% or 0.975

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population mean or variance lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

The Chi Square distribution is the distribution of the sum of squared standard normal deviates .

Calculating the confidence interval

The confidence interval for the population variance is given by the following formula:

$\frac{(n-1)s^2}{\chi^2_{\alpha/2}} \leq \sigma^2 \leq \frac{(n-1)s^2}{\chi^2_{1-\alpha/2}}$

The next step would be calculate the critical values. First we need to calculate the degrees of freedom given by:

$df=n-1=18-1=17$

Since the Confidence is 0.975 or 97.5%, the value of $\alpha=0.025$ and $\alpha/2 =0.0125$ , and we can use excel, a calculator or a table to find the critical values.

The excel commands would be: "=CHISQ.INV(0.0125,17)" "=CHISQ.INV(0.9875,17)". so for this case the critical values are:

$\chi^2_{\alpha/2}=32.64$

$\chi^2_{1- \alpha/2}=6.66$

And replacing into the formula for the interval we got:

$\frac{(17)(0.038)^2}{32.64} \leq \sigma^2 \leq \frac{(17)(0.038)^2}{6.66}$

$0.0008 \leq \sigma^2 \leq 0.0037$

The least common denominator of two fractions is 20. If you subtract the two denominations, you get 1. What are the denominators

LekaFEV [45]

Steps
find the Least Common Multiple of the denominators (which is called the Least Common Denominator).

Change each fraction (using equivalent fractions) to make their denominators the same as the least common denominator.

Then add (or subtract) the fractions, as we wish!
your denominators stay the same so its 20

What is the value on the number line for the blue dot

rosijanka [135]

Answer:

I believe 4, but I might be wrong.

Step-by-step explanation:

If you look, it's going down -4 every time. So that means if you're going up, it's going +4 after you skip a space. So, skip, then 0, then skip, and that's 4.

What are the x-intercepts of the following graph? On a coordinate plane, a parabola opens down and goes through (negative 2, 0),

pshichka [43]

Answer:

Step-by-step explanation:

If you read the question carefully, you find that the function goes through (- 2,0) and (2,0)

Where the y value = 0 you have points that are x intercepts. The answer is anything where the y value = 0

The x intercepts are (-2, 0 ) and (2,0)

The answer is C
