Answer:
The second term of the binomial factor should be 3c instead of 3.
Step-by-step explanation:
Distributive property:
a*b + a*c = a*(b +c)
3b + 9c = 3*b + 3* 3 *c = 3*(b + 3c)
Answer:
A. 64/125
B. 124/125.
Step-by-step explanation:
A). As the events ( germinate or not germinate) are independent we multiply the probabilities.
Prob(All seeds germinate) = 4/5*4/5*4/5 = 64/125.
B). Probability of at least one germinating = 1 - probability that none germinate
Probability of 1 seed not germinating = 1 -45 = 1/5.
So Prob(at least one germinating)
= 1 - (1/5 * 1/5 * 1/5)
= 1 - 1/125
= 124/125.
Answer:
b=-1
Step-by-step explanation:
given.3b+(-5)=(2b)³(-3)2+6=?
3b-5=8b-6+6
3b-5=8b
-5=8b-3b
-5=5b
-5/5=5b/5
b=-1
-3-5=-8-6+6=?
-8=-8=-8
Answer:
1/12, 1/10
Step-by-step explanation:
P(Bead bracelet and red shoes) - 3/3 x 2 x 2
3/12=1/4 for bead bracelet
Red shoes - 1/3
Total probability for P(Bead bracelet and red shoes=1/4 x 1/3=1/12
P(Elastic bracelet and black shoes)
2/3 x 2 x 2
2/12=1/6 for elastic bracelet
Black shoes - 3/5
Total probablility for P(Elastic bracelet and black shoes)=1/6 x 3/5=3/10=1/10
Hope I helped!
