If you have used a fraction strip to name a specific point between 0 and 1 on a number line, how can you find equivalent fractio

Tatiana [17]

Answer:

1/2

Step-by-step explanation:

On a number line, a specific point between 0 and 1 would be a decimal number because:

0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1

If I wanted to name a particular point using a fraction strip, say 0.5 on the number line, I would say 5/10(count 5 numbers till 0.5 divided by total count of numbers).

0.5 would therefore be half/mid point between 0 and 1

If I wanted to get an equivalent fraction for this, I could reduce 5/10 to its lowest terms to get 1/2 which has same value(half) but different numerator and denominator.

Equivalent fractions have different numerators and denominators but are the same in value, example 2/4, 50/100, 9/18 etc are all the same with 5/10 or 1/2 above

How do I make this bell curve

Zanzabum

The mean you found is correct, but the standard deviation is not. Recall that the standard deviation $\sigma_s$ ( $s$ for sample) of $n$ points is given by

$\sigma_s=\sqrt{\dfrac1{n-1}\displaystyle\sum_{1\le i\le n}(x_i-\bar x)^2}$

where $n=10$ is the sample size, $\bar x=3740$ is the sample mean, and $x_i$ are the prices listed in the circled column. So

$\sigma_s=\sqrt{\dfrac{(3640-3740)^2+(7595-3740)^2+\cdots+(3390-3740)^2}{10-1}}$

$\implies\sigma_s\approx1443.98\approx1444$

I can't tell if you need to provide any more info beyond this, but given there's a plot of a generalized bell curve, I think you're also supposed to label the plot.

At the center of the bell-shaped/normal distribution is the mean. Notice there are three tick marks to either side of the mean - these are probably supposed to represent prices that fall exactly 1, 2, and 3 standard deviations from the mean. These are, from left to right,

$\bar x-3\sigma_s\approx3740-3(1444)=-592$

$\bar x-2\sigma_s\approx3740-2(1444)=852$

$\bar x-\sigma_s\approx2296$

$\bar x+\sigma_s\approx5184$

$\bar x+2\sigma_s\approx6628$

$\bar x+3\sigma_s\approx8072$
