Answer:

B) 0.55

The probability of the complement of Event A ( P( A⁻ ))  = 0.55

Step-by-step explanation:

<u>Explanation</u>:-

<em>  Given  Event A and Event B are mutually exclusive.</em>

<em>   Given data P(A) = 0.45 </em>

<em>                      P(B) = 0.35</em>

<em>                      P(C) = 0.25</em>

<em>The probability of the complement of Event A</em>

<em>                    P( A⁻ ) = 1 - P( A)</em>

                              =  1 - 0.45

                              = 0.55

<u><em>Final answer</em></u>:-

<em>The probability of the complement of Event A = 0.55</em>

Diego said that the awnser to the question "How many groups of 5/6 are in 1?" Is 6/5 or 1 1/5.Do you agree with his statement? E
slamgirl [31]

Answer:

Diego is correct.

He has correctly divided 1 in groups of \frac{5}{6}.

Step-by-step explanation:

The question 'How many groups of 5/6 are in 1?'  means that we need to divided 1 into groups of \\frac{5}{6}.

When we form groups from a given total, we divided the total by the size of the group.

If we are dividing N number of people in groups of x number of people, then the expression to find the number of groups formed can be given as:

⇒ \frac{N}{x}

For this question the data given is:

N=1

x=\frac{5}{6}

So, the number of groups formed can be given as:

⇒ \frac{1}{\frac{5}{6}}

When divisor is a fraction, then we multiply the reciprocal of the divisor with the dividend.

⇒ 1\times\frac{6}{5}

⇒ \frac{6}{5}

In order to convert fraction to mixed number we will divide numerator with denominator and then write the quotient as whole number, remainder as numerator and the denominator remains as it is.

On dividing 6 by 5, the quotient =1 and remainder =1. Thus the mized number is:

⇒ 1\frac{1}{5}

Thus, there are \frac{6}{5} or 1\frac{1}{5} groups in 1. This matches with Diego's answer and hence he is correct.

In the figure to the right, AE + DC = 1 1/5 cm, AB = 1 3/4 cm, DE = 1 1/4 cm, and BC = 1 3 /10 cm. Find the perimeter of the fig
pentagon [3]

Answer:

The perimeter of the figure = 9.5 cm

Step-by-step explanation:

<em>Note: You probably missed to add the figure, but after a little research I found and am attaching the figure. I have answered your question based on the reference of that figure. But, I hope you would learn the concept so that you could solve any question based on this concept. So, please check the figure.</em>

<em>Solution:</em>

The perimeter of the figure is the sum of all the sides of the given figure as shown in the attached figure.

So, here is the formula to calculate the perimeter.

                <em>Perimeter </em>=<em> AB + DE + BC + AE + BC  </em>

As AE + DC = 1 1/5 cm, AB = 1 3/4 cm, DE = 1 1/4 cm, and BC = 1 3/10 cm

Therefore,

<em>Perimeter</em> = 1 3/4  + 1 1/4  + 13/10 + 1 1/5           ∵ AE + BC = 1 1/5

                                   = (130  + 110  + 52 + 88) / 40

                                   = 380/40  

                                   = 9.5 cm

So, the perimeter of the figure is = 9.5 cm
