"Tossing a die" is assumed to mean choosing a random face of a cube with faces numbered 1 through 6 such that the probability of choosing any particular face (number) is 1/6.

Event <em>a</em> is "observe a 2". Event <em>b</em> is "observe an even number". The event "<em>a</em> and <em>b</em>" is "observe 2 and an even number". This matches precisely the description for event <em>a</em>. In other words

... <em>a</em> and <em>b</em> = <em>a</em>

... p(<em>a</em> and <em>b</em>) = p(<em>a</em>) = p(choosing 2) = 1/6

Answer:

<u>Option-</u> B

  • An experiment involves tossing a die. these are some of the events during which we can be able to observe an even number.                                                                                                                      

Step-by-step explanation:

  • It is more obviously to know that there will be six sides for us to observe and each time we will get an even number to observe during the process.So, it all goes with the mechanisms of the probability that are taken under considerations when we speak about such events to happen.

Kiana wants to write equations in the form y = mx + b for the lines passing through
horrorfan [7]

Answer:

'Substitute the slope and the coordinates of point P(-3,2) in y = mx + b and then solve for b in each equation'.

Step-by-step explanation:

Kiana wants to write equations in the form y = mx + b for the lines passing through point P that are parallel and perpendicular to line q.  

This equation is in the slope-intercept form where m is the slope and b is the y-intercept.

First, she finds the slope of line q and the slope of line s to be – 2. Point P is located at (-3,2).

Therefore, the step that can be used to find the y-intercept is 'substitute the slope and the coordinates of point P(-3,2) in y = mx + b and then solve for b in each equation'. (Answer)

Solve this equation:<br> 7x - [5 + (3x - 2)] = x - (4x - 5) + (2x - 1)
Vedmedyk [2.9K]

Answer:

x = 7/5

<em>I</em><em> </em><em>hope this</em><em> </em><em>helps</em><em> </em>

Step-by-step explanation:

7x - [5 + (3x - 2)] = x - (4x - 5) + (2x - 1)

7x - 5 -3x +2 = x -4x +5 +2x -1

4x -3 = -x +4

4x +x = 4+3

5x = 7

x = 7/5

Can you Solve. 3x^2+10x+3
Alika [10]
You cannot solve for x but you can factor

to solve in ax^2+bx+c form you must find
b=x+y
a times c=x times y

so solve

3 times 3=9

what 2 number multily to get 9 and add to get 10
9=x times y
the numbers are 9 and 1 so

3x^2+1x+9x+3
(3x^2+1x)+(9x+3)
factor
(x)(3x+1)+(3)(3x+1)
reverse distribute
ab+ac=a(b+c)

(x)(3x+1)+(3)(3x+1)=(x+3)(3x+1)
factored out form is (x+3)(3x+1)
