Answer:

a. Inferential statistics

b. Descriptive statistics

Step-by-step explanation:

statistics can be categorized into descriptive an inferential statistics. descriptive statistics makes use of a set of data for numerical calculations and provides conclusion based on those numerical calculation. this data could be collected using tables,graphs, and other means of data representation.

Inferential statistics however come up with conclusions and assumptions base on a sample data.

Examples of descriptive statistics are mean, median, mode, quartile, percentile. Thus option B is descriptive.

Option A however is inferential statistics since some assumptions were made based on the effect of garlic on blood pressure.

Simplify expression X^2+x-2/x^3-x^2+2x-2

professor190 [17]

Answer:

$=\frac {x+2}{x^2+2}$ is the simplest form of given expression.

Step-by-step explanation:

The given question is $\frac{x^2+x-2}{x^3-x^2+2x-2}$

To solve the problem we have to group or split middle term and then factorise

$\frac{x^2+(2x-x)-2}{(x^3-x^2)+(2x-2)}$

Taking $x^2$ common from first two terms of denominator and 2 from next two terms

$= \frac{x^2+2x-x-2}{x^2(x-1)+2(x-1)}$

Now,taking x common from first two terms of numerator and -1 from next two terms and in denominator taking(x-1) common from both terms

$= \frac{ x(x+2)-1(x+2)}{(x-1)(x^2+2)}$

$=\frac{(x+2)(x-1)}{(x-1)(x^2+2)}$

Now cancel out x-1 from both numerator and denominator we get

$=\frac {x+2}{x^2+2}$ is the required simplest form.

Solve x: 3x-7 = 5x+13 <br> Solve x: 7-3x = 5x+13

Svetach [21]

First you need to combine like terms
7-3x= 5x+13
step 1 add 3x
7=8x+13
step 2 subteact 13
-6=8x
step 3 divide both sides by two
x=-3/4

Answer:

the handle will end up on the left side

Step-by-step explanation:

The cup is rotated 180 degrees clockwise. Therefore, I assume the rotation is about the center of the bottom of the cup. Also, only the cup is rotated, not the saucer (although this makes no difference in this problem).

The result is that the handle will end up on the left side. The cup will still be right side up.
