First, we already have the perimeter and the sides that we need to find the 5th sides. Next, add all available sides that we have: 5+5+4+4=18. Finally, we need to subtract 27 to 18 to get the final answer is 9 for the 5 the side. Hope you get it.

I'd say

Put one end of the compass on point P and the other end on point Q.

This way, you can construct (part of) a circumference with radius PQ with center P.

If you connect point P with any point on the circumference, this segment will be another radius of the circumference, and thus congruent to PQ.

In an assembly-line production of industrial robots, gearbox assemblies can be installed in one minute each if holes have been p
Illusion [34]

Answer:

The right answer is:

(a) 0.1456

(b) 18.125, 69.1202, 8.3139

Step-by-step explanation:

Given:

N = 24

n = 5

r = 7

The improperly drilled gearboxes "X".

then,

⇒ P(X) = \frac{\binom{7}{x} \binom {17}{5-x}}{\binom{24}{5}}

(a)

P (all gearboxes fit properly) = P(x=0)

                                               = \frac{\binom{7}{0} \binom{17}{5}}{\binom{24}{5}}

                                               = 0.1456

(b)

According to the question,

X = 91+5

Mean will be:

⇒ \mu = E(x)

       =E(91+5)

       =9E(1)+5

       =9.\frac{nr}{N}+5

       =9.\frac{5.7}{24} +5

       =18.125

Variance will be:

⇒ \sigma^2=Var(X)

         =V(9Y+5)

         =81.V(Y)

         =81.n.\frac{r}{N}.\frac{N-r}{N}.\frac{N-n}{N-1}

         =81.5.\frac{7}{24}.\frac{24-7}{24}.\frac{24-5}{24-1}

         =69.1202

Standard deviation will be:

⇒ \sigma = \sqrt{69.1202}

       =8.3139

PLEASE HELP FOR EACH OF THE FIGURES, WRITE AN ABSOLUTE VALUE EQUATION
Likurg_2 [28]

The solution set 0 and 8 are the true values of the absolute value equation

The absolute value equation that has the a solution set of 0 and 6 is |x - 3| = 3

<h3>How to determine the absolute value equation?</h3>

From the figure, the solution sets of the absolute value equation are given as:

x = {0, 6}

Calculate the mean of the solution set

Mean = 0.5 * (0 + 6)

Mean = 3

Calculate the difference of the solution set divided by 2

Difference = (6 - 0)/2

Difference = 3

The absolute value equation is the represented as:

|x - Mean| = Difference

Substitute known values

|x - 3| = 3

Hence, the absolute value equation that has the a solution set of 0 and 6 is |x - 3| = 3
