Answer:

sin^2(45) = (√2/2)^2 = 1/2

Step-by-step explanation:

sin2x = sin2 * x = 0.909x

sin(2(45)) = sin90 = 1

Hope this helps.

Given Event A, Event B, and Event C. Event A and Event B are mutually exclusive. Event A and Event C are not mutually exclusive.
weeeeeb [17]

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>

\large\underline{\sf{Solution-}}

\textsf{Given expression;}\\

\rm{23 =  \frac{7}{9}(6x - 36) + 9 } \\

\rm{\longmapsto} \: 23 =  \frac{(42x - 256)}{9}  + 9 \\

\rm{\longmapsto} \: 23 =  \frac{(42x - 256 + 81)}{9}  \\

\rm{\longmapsto} \: 23 =  \frac{(42x - 175)}{9}  \\

\rm{\longmapsto} \:  \frac{23}{1}  =  \frac{(42x - 175)}{9}  \\

\textsf{By doing cross multiplication, we get}\\

\rm{\longmapsto}23(9) = 1(42x - 175) \\

\rm{\longmapsto}207 =42x - 175\\

\rm{\longmapsto} \: 42x =  - 175 - 207 \\

\rm{\longmapsto} \: 42x =  - 379 \\

\rm \therefore \: x =  -  \frac{375}{42}  \\

\textsf{Hence, the value of x will be -375/42 respectively.}\\

A number multiplied by 12 is equal to the sum of the square root of that same number and 36. What is that number?
Pavlova-9 [17]

Answer:

3.15

Step-by-step explanation:

Let the unknown number be n.

Then 12n = √n + 36

We must eliminate the √ operator.  One way to do this is to replace √n temporarily with x.  Then 12n = 12x^2, and we have 12x^2 - x - 36 = 0.  This is a quadratic with a= 12, b= -1 and c = -36

Solving for x using the quadratic formula:

       1 plus or minus √(1 - 4(12)(-36)

x = ----------------------------------------------

                        2(12)

      1 plus or minus √1729

x = -----------------------------------

                        24

       1 plus or minus 41.58

x = -----------------------------------

                    24

Since x = √n, n must be a positive number.  Thus,

       1 + 41.58

x = ---------------- = 1.77

            24

If x = 1.77 = √n, then n = 1.77^2 = 3.15.

Check:  Is this true?  A number multiplied by 12 is equal to the sum of the square root of that same number and 36.

12(3.15) = √3.15 + 36, or

 37.8    =  1.77 + 36  = 37.77     This checks out.

The number is 3.15
