Question 4
Ilia_Sergeevich [38]

Answer:

2

Step-by-step explanation:

Given

See attachment for chart

Required

Number of off days

To do this, we simply calculate the expected value of the chart.

This is calculated as:

E(x) = \sum x * f

Where

x = days

f = chances

So, we have:

E(x) = 0* 0.3 + 1 *0.2 + 2 * 0.25 + 3  * 0.2 + 4  * 0.02 + 5 * 0.01 + 6 * 0.01 + 7 * 0.01

E(x) = 1.56

E(x) \approx 2

How many solutions does this equation have? 6x+5=4x+5
Travka [436]

:\implies \sf  6x +5 = 4x +5

: \implies \sf  6x +5 -4x = 5

:\implies \sf  2x = 5-5

:\implies \sf  2x = 0

:\implies \sf  x = 0

Seems like "6x+5=4x+5" has only one solution that's 0.

State when the following equations and inequalities will be true and when they will be false.
-BARSIC- [3]

' 36 = 9k ' is not an inequality.  It's an <u>equality</u>, usually called an <em><u>equation</u></em>.

It's true whenever 'k' is 4, and false at any other time.

(You can determine that simply by dividing each side of the equation by 9.)
