Answer:

Step-by-step explanation:

Some of the expressions that can be derived that have the values of 12 are:

i. 2a = 2 x 6

      = 12

ii. 3b = 3 x 4

        = 12

iii. (b  + c) x a = (4 - 2) x 6

                = 2 x 6

                = 12

iv. 2b + c^{2} = (2 x 4) + (-2 x -2)

                = 8 + 4

                = 12

v. b^{2} -  c^{2} = (4 x 4) - (-2 x -2)

             = 16 - 4

             = 12

vi. c^{4} - b = (-2 x -2 x -2 x -2) + 4

             = 16 - 4

             = 12

(3-0/4a)-(10-0.8a). Solve for a
torisob [31]

An equation is formed of two equal expressions. The value of 'a' in the given equation is 6.452.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The given equation can be solved for 'a' as shown below,

\dfrac{(3-0)}{4a} = (10-0.8a)\\\\\dfrac{3}{4a} = (10-0.8a)\\\\

0.75a = 10 - 0.8a

0.75a + 0.8a = 10

1.55a = 10

a = 6.452

Hence, the value of 'a' in the given equation is 6.452.

A spinner is divided into six equal-sized sectors labeled 1 through 6. Dwayne spins this spinner 12 times. Let X
slavikrds [6]

Answer:

b) μ = 2 and σ = 1.29

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6</em>

<em>Given that the probability of labelled '1'</em>

<em>                       </em>p = \frac{1}{6} =0.16

<em>                      q = 1-p =  1- 0.16 = 0.84</em>

Let 'X' be a random variable in binomial distribution

The mean of the binomial distribution

      μ = n p

     μ  =  12 (\frac{1}{6} ) = 2  

<em>The mean of the binomial distribution  = 2</em>

<u><em>Step(ii):-</em></u>

The standard deviation of X

                σ = \sqrt{npq}

               σ = \sqrt{12(0.16)(0.84}

                  σ = 1.269

<em>The standard deviation of the binomial distribution</em>

<em>                </em> σ = 1.269

<u><em></em></u>

STRUCTURE Without graphing or solving, determine the number of solutions of the system.
Mkey [24]
I believe the answer would be "infinitely many solutions" because you can put any number as x and y would be a different answer each time for both of the equations given. i hope this helps :)

What is the area of a circle with a diameter of 24 meters (use 3.14 for Pi)?
Zarrin [17]

The area of a circle is represented by the equation:


A=\pi r^{2}


We know that the diameter is two times the radius: d=2r


So if we know that the diameter of the circle is 24m, we can divide this by two in order to get the radius:


24m=2r -->r=12m


So then we can plug this radius in to the equation for the area of a circle:


A=\pi (12)^{2}


A=144\pi


We are told to use 3.14 as pi, and not pi itself, so let's plug in 3.14 for pi:


A=3.14(144)


A=452.16m^{2}


Now we know that the area of this circle is 452.16 square meters.
