hello,

Step-by-step explanation:

a)

p(fail)=0.05

p(not fail)=1-0.05=0.95

b)

p(3 fails)=0.05³=0,000125

c)

p(1 or more system not fail)=1-0.05³=0.999875

A lecture hall contains $20$ chairs, all lined in a row. What is the number of ways that five chairs can be chosen, so that no t

patriot [66]

Answer:

Step-by-step explanation:

If we choose chairs having odd number in the row

no of chairs from which selection is made = 10

no of chairs to be selected = 5

no of ways = 10C₅

similarly if we choose hairs having even numbers only ,

similar to above , no of ways

= 10C₅

Total no of ways

= 2 x 10C₅

= 2 x 10 x 9 x 8 x 7 x 6 / 5 x 4x3 x 2 x 1

= 504 .

If m RDC = 120°, then m DAC=?

monitta

The correct answer to this question is 240

From the image i've seen, the RDC has an angle of 120. So the major arc DC (that passes A and B) has an angle of 240.

So this makes that the measure of the angle of DAC is 240 because of the angle formed by RDC which is 120.

Left to Right

<u>Algebra II</u>

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Find points from graph.</em>

Point A(1, 4)

Point B(-2, -3)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance<em> d</em>

Substitute in points [DF]: $\displaystyle d = \sqrt{(-2-1)^2+(-3-4)^2}$
(Parenthesis) Subtract: $\displaystyle d = \sqrt{(-3)^2+(-7)^2}$
[√Radical] Exponents: $\displaystyle d = \sqrt{9+49}$
[√Radical] Add: $\displaystyle d = \sqrt{58}$
[√Radical] Evaluate: $d = 7.61577$
Round: $\displaystyle d \approx 7.62$
