Answer:
0.3277 = 32.77%
Step-by-step explanation:
If we want the probability for Sasha being late after the fifth day, we need that in the first five days she is not late, which has a probability of 1 - 0.2 = 0.8
So, multiplying the probability for each day, we have that:
P = 0.8 * 0.8 * 0.8 * 0.8 * 0.8 = 0.3277 = 32.77%
So we have a probability of 32.77% that Sasha's first delay will occur after the fifth day.
Y= 3 which would be choice A, because both equations are going to be set equal to eachother, so with that you would put

subtract 5y from 7y, and add the 3 from the left to the 3 on the right. this would leave you with 2y=6 so in this case you would divide both sides by two to get the answer of 3 which is choice A.
To get the answer you have to find the least common denominator of 7 and 6. the answer is 42. so you multiply 4/7 by 6/6 to get 24/42 then you multiply 5/6 by 7/7 to get 35/42. the last step is to subtract 24/42 from 35/42 to get your final answer 11/42
Answer:
x=25
Let's solve your equation step-by-step.
3x+18=93
Step 1: Subtract 18 from both sides.
3x+18−18=93−18
3x=75
Step 2: Divide both sides by 3.
