Answer:
0.6535
Step-by-step explanation:
Given that during a one-hour period twenty-five customers buy gasoline at this station.
Let X be the no of persons out of these 25 who pay by cash.
X has two outcomes and each trial is independent of other.
Hence X is binomial (n=25, p=0.40)
Required probability
=
=0.6535
<em>First we have to find the factors of 15x³y²</em>
<em>15x³y² = 3 * 5x³y² </em>
<em>Then we have to find the factors of 20x⁴y⁴</em>
<em>20x⁴y⁴ = 2²x¹y² * 5x³y²</em>
<em>Now we have to find the common factors to both numbers.</em>
<em>The common factors are </em><em>5x³y²</em>
Answer : GCF = (15x³y²,20x⁴y⁴) = 5x³y²
Hope this helps!
