Answer:
y < 5
Step-by-step explanation:
22-3y>7
1.) -3y > 7-22 subtract both sides by 22 so you get -3y > -15
2. ) y < -5 divide both sides by -3
then flip the inequality sign because you're dividing by a negative number.
Answer:7
Step-by-step explanation:
8+4=12
2(x-1)= 2x-2
12=2x-2
now add 2 to both sides
14=2x
And divide both sides by 2
7=x
Step-by-step explanation:
Given that Rita is making a beaded bracelet. She has a collection of 160 blue beads, 80 gray beads, and 240 pink beads. We are to calculate the probability that Rita will need to pick atleast 5 beads before she picks a grey bead from her collection.
Prob for drawing atleast 5 beads before she picks a grey bead from her collection
= 1-Prob for drawing atleast one grey beed in the first 5 draws.
(Because these two are complementary events)
no of grey beeds drawn in first 5 trials is
Bi=(5,1/6)
Prob for drawing atleast one grey beed in the first 5 draws.
=1-Prob of no grey
Hence required prob=P(X=0 in first 5 draws)
= 0.4018
6th beeds onwards can be grey also.
Nearest answer is c)0.45
