Answer:

Figure 3 shows the shaded area for (C\cup B)\cap A'.

Step-by-step explanation:

It is given that A, B and C are three different sets. U is the universal set.

We need to find the shaded area for (C\cup B)\cap A'.

Here,

\cup = Union

\cap = Intersection

Now,

(C\cup B) means either C or B.              .... (1)

A'=U-A means all part U except A.           .... (2)

The shaded region for both conditions is shown below.

(C\cup B)\cap A' is intersection of (1) and (2).

So, the final shaded reason is shown in figure 3.

Answer:

In mathematics, the intersection A ∩ B of two sets A and B is the set that contains all elements of A that also belong to B (or equivalently, all elements of B that also belong to A), but no other elements. For explanation of the symbols used in this article, refer to the table of mathematical symbols.

We just saw how to join two sets using "Union" (and the symbol ∪). There is also "Intersection" which means "has to be in both". Think "where do they overlap?". The Intersection symbol is an upside down "U" like this: ∩

it is this because it says to shade b and c so i did that but also it says to shade u and it says u is n and n is a so you shade b c and a

16. write an inequality for each graph
Harrizon [31]

Answer:

Question 16

(a) x < 1 : the values of x are smaller than than 1 (e.g. possible values are 0, -1, -2, etc) and since the circle is not shaded it means that 1 isn't a possible value of x

(b) x \geq -2 : the circle is filled therefore -2 is included in the answer

Question 17

(a) unfilled dot above -2 and arrow pointing to the left

(b) shaded circle above 4 with and arrow pointing to the right →

ale4655 [162]

Answer:

A data set consists of 2,2,3,4,5,5 and 7. Then, 20 is added to the data set. The new value will have the little effect on the median, but it will raise the mean significantly.

Step-by-step explanation:

Since, we all know that the measures of central tendency are:

  1. Arithmetic Mean
  2. Median
  3. Mode
  4. Geometric Mean
  5. Harmonic Mean

Let us define Arithmetic Mean and Median.

Arithmetic mean is the sum of observations divided by the total number of observations. It is denoted by (x bar).

On the other hand, median of a distribution is that value of the variable which divides it into two equal parts.

For Arithmetic Mean:

According to the question, when data set consists 2,2,3,4,5,5 and 7, the arithmetic mean for the given data = 4

After adding 20 the given data set, the mean will be = 6

For median:

When data set consists of 2,2,3,4,5,5 and 7, the median value will be the middle value of the distribution i.e. = 4

After adding 20 to the given data set, the median will be = 4.5

Here we can say that 20 is an outlier for the given data set.

Since mean has the significant effect of the outlier because it is based on all values but the median has lesser effects of the outlier as it is based only on middle values. So whatever outlier is added to median, it will not show particular changes.

Thus , a data set consists of 2,2,3,4,5,5 and 7. Then, 20 is added to the data set. The new value will have little effect on median, but it will raise the mean significantly.
