P(B) = 0.75.
For independent events, P(A and B) = P(A)*P(B). This gives us
1/8 = 1/6(x)
Divide both sides by 1/6:
1/8 ÷ 1/6 = x
1/8 × 6/1 = x
6/8 = x
3/4 = x
0.75 = x
Answer:
step one simply hope it helped!
Step-by-step explanation:
So remember that one property of kites is that their non-vertex angles, in this case Angle B and D, are congruent to each other. And now that we know 3/4 angles of this kite, we can set up an equation to find Angle A.
Since quadrilaterals' interior angles add up to 360°, our equation can be set up as such: 85 + 85 + 140 + A = 360 . From here we can solve for A.
Firstly, add everything on the left side: 310 + A = 360
Next, subtract 310 on both sides, and your answer will be: A = 50°
<span>since the coefficients add to 0 we know that one root is x = 1 , do synthetic division ; </span>
<span>(x - 1 ) ( 2 x^3 - 5 x² - x + 6 )...now it is easy to see that x = - 1 is a root; </span>
<span>again synthetic division yields ( x - 1 ) ( x + 1 ) [ 2 x² - 7 x + 6 ]]....so </span>
<span>the smallest upper bound is x = 2 { poly = 0 at x = 2 }.. </span>
<span>thus both 4 & 5 are upper bounds </span>
<span>and since you only ask to find an upper bound then x = 1000 is certainly an answer ; </span>
<span>finally if you write the polynomial as " x [ x ( x {2x - 7 } + 4 ) + 7 ] - 6 " </span>
you can see that x = 3 is an upper bound
