Find the difference between 6/7 and 2/3 in lowest terms.
kramer

As per the problem,

we have been asked to find the difference of the given fractions.

The given fractions are \frac{6}{7} \ and \ \frac{2}{3}

\frac{6}{7}-\frac{2}{3}

Make denominator equal and simplify we get

\Rightarrow \frac{6}{7}-\frac{2}{3} =\frac{6}{7}*\frac{3}{3}-\frac{2}{3}*\frac{7}{7}  \\\\\Rightarrow \frac{6}{7}-\frac{2}{3} =\frac{18}{21}-\frac{14}{21} \\\\\Rightarrow \frac{6}{7}-\frac{2}{3} =\frac{18-14}{21}\\\\\Rightarrow \frac{6}{7}-\frac{2}{3} =\frac{4}{21}

The difference of the given fractions=4/21

Renee scores an average of 153 points in a game of bowling, and her points in a game of bowling are normally distributed. Suppos
Lelu [443]

Answer:

\sigma=\frac{175-153}{2}=11

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Let X the random variable that represent points in a game of bowling of a population, and for this case we know the distribution for X is given by:

X \sim N(153,unknown)  

Where \mu=153 and \sigma=?

We know that the value for Renee is X=175 and the z score obteined was Z=2.

Solution to the problem

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{X-\mu}{\sigma}

We are interested on the value of \sigma and we can solv for it:

z \sigma = X-\mu

\sigma=\frac{X-\mu}{z}

And replacing the values we have:

\sigma=\frac{175-153}{2}=11

Which functions have graphs with slopes less than -2?<br> (Check all that apply.)
Norma-Jean [14]

Answer:

Function 2

Step-by-step explanation:

✔️Slope of function 1:

Slope (m) = ∆y/∆x

Using two points on the line, (0, 4) and (1, 9),

Slope (m) = (9 - 4) / (1 - 0)

Slope (m) = 5/1

Slope (m) = 5

✔️Slope of function 2:

Slope (m) = ∆y/∆x

Using the coordinates of any two given pairs form the table, (0, 1) and (1, -3):

Slope (m) = (-3 - 1) / (1 - 0)

Slope (m) = -4/1

Slope (m) = -4

✔️Slope of Function 3:

The function is given in the slope-intercept form, y = mx + b

m = slope

The function y = 2x - 5, therefore has a slope (m) of 2

Slope = 2

✔️Slope of Function 4:

Slope (m) = -1

✅Thus, the functions that has slopes less than -2 are:

Function 2: slope = -4

Function 1, 3, and 4 all have slopes that are greater than -2
