Write the set that represents the set of people surveyed who subscribe to at least one of the two news sources given.

Soloha48 [4]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct option is d

Step-by-step explanation:

From the question we are told that

The set of people in a certain community who were asked if they subscribe to an information source is U

The set that subscribes to The Daily Informer is D

The set that subscribe to News Magazine is N

Here the universal set is U

Now the word at least here means that the person can subscribe to one or two of the information source , but the person cannot subscribe none of the information source

Now to get the set that represents the set of people surveyed who subscribe to at least one of the two news sources , we need to carry out a union operation on the sets representing the two news source , this can be mathematically represented as

$L = N \ u \ D$

So the sets that will contain all the people in the community that subscribe to at least one of the news source is L

Using suitable identity evaluate the following : 98^3

stiv31 [10]

941,192

Steps:

$(a-b)^3=a^3-b^3-3a^2b+3ab$

$\begin{gathered} (98)^3=(100-2)^3 \\ (100-2)^{3\text{ }}=(100)^3-(2)^3-3\cdot(100)^2\cdot2+3\cdot100\cdot2^2\text{ } \\ (100)^3-(2)^3-3\cdot(100)^2\cdot2+3\cdot100\cdot2^2\text{ = 1,0}00,000\text{ - 3 - 60,000 +1,200} \\ \text{ 1,0}00,000\text{ - 3 - 60,000 +1,200 = 941,192} \end{gathered}$

In your own words, how geometric seqences are related to exponetiol functions

CaHeK987 [17]

Answer:

Geometric sequences are exponential functions

Step-by-step explanation:

Geometric sequences are exponential functions.

The general term of a geometric sequence is given by the exponential function ...

a[n] = a[1]·r^(n-1)

where a[1] is the first term and r is the common ratio.

You will notice that the independent variable (n) is in the exponent of this function. Hence it is an exponential function.

What is 1/4 of 3/5 of customers

shepuryov [24]

The answer is 7/20. 1/4= 5/20 and 3/5 = 12/20 What I did was find the GCF (greatest common factor) of both 4 and 5 which was 20. Then I multiplied both numerators by the same number I multiplied the denominator with. Afterwards I subtracted both numerators (12-5) and this equals to 7 Hope that helps
