Answer: could we see the expressions please?
Step-by-step explanation:
Answer:
b. 0.45.
Step-by-step explanation:
The total possible outcome of a probability is 1
Given;
Probability that both lights will be red when she reaches them = 0.22
Probability that the first light will be red and the second light will not be red = 0.33
Probability that the second light will be red when she reaches it = x
These are all the possible outcomes, therefore
0.22 + 0.33 + x = 1
0.55 + x = 1
x = 1 - 0.55
x = 0.45
Option b
B = 2r - 10
b = 56
56 = 2r - 10
56 + 10 = 2r
66 = 2r
66/2 = r
33 = r <=== there are 33 rabbits
Answer:
B)-4
Step-by-step explanation:
y=mx+c
sub in a point and gradient/slope to get c
-7=3(-1)+c
-7=-3+c
-7+3=c
c=-4
y=3x-4
if u looking for the y intercept make x=0
y=3(0)-4
y=-4
