Answer: 0.27
Step-by-step explanation:
Given that :
Probability of being a strike ; p(strike) = 0.3
Note : the probability of each pitch Beau is independent :
Probability that next three will be a strike :
p(strike) * p(strike) * p(strike)
= 0.3 * 0.3 * 0.3
= 0.27
<span>0.25x2+0.8x−8=0
same as 5x^2+16-160=0 no obvious factors for rational roots, so use quadratic formula
−(x−3)(x+9)=0 .... the factors are clearly (x-3) and (x+9), no need for formula
3x² = 9 ..... we see x^2=3, so roots are ± sqrt(3), no need for formula.
−2x2+5x=7 .... here b^2<4ac, definitely use quadratic formula.</span>
Answer:
Step-by-step explanation:
Factorise the denominator of the second fraction
y² - 1 = (y - 1)(y + 1) ← difference of squares
To obtain a common denominator
multiply numerator/ denominator of first fraction by (y + 1)
= - ← subtract numerators leaving the common denominator
=
=
= ← cancel common factor (y - 1) on numerator/denominator
=
