Tomorrow night at ten because 48 hours is two days. So two days from last night at ten.
B
Because the slope is 3.5 so they cost 3.50 per pound
36/12=3 Which give you the enlargement of the smaller triangle to the bigger one.
You work out the missing side by putting it into an equation:
3(x-10)=39
Then solve it.
First expand the brackets:
3x-30=39
The rearrange to get x on its own and that will be your answer:
3x=39+30
3x=69
x=69/3
x=23

Answer:
( a ) Probability that the test comes back negative for all four people = .9723
( b ) Probability that t he test comes back positive for at least one of the four people = .0277
Step-by-step explanation:
Given
The probability of the test will accurately come back negative if the antibody is not present = 99.1
= .991
The probability of the test will accurately come back positive if the antibody is not present = .009
Suppose the test is given to four randomly selected people who do not have the antibody .
( a ) Probability that the test comes back negative for all four people =
=
= .9723
If we say E = P( all 4 test are negative) or we say E = P( not of the all 4 test are positive)
P( at least one of the 4 test are positive) = 1 - P( not of the all 4 test are positive) = 1 - P( all 4 test are negative)
( b ) Probability that t he test comes back positive for at least one of the four people = 1 - P( all 4 test are negative)
= 1 - .9723
= .0277
