Answer:
- ∠ZXW and ∠ZXY are right angles
Step-by-step explanation:
- <em>Two right triangles are congruent if the hypotenuse and one corresponding leg are equal in both triangles</em>
<u>We have indication of:</u>
Missing information is just confirmation that both of them are right triangles
<u>This is:</u>
- ∠ZXW and ∠ZXY are right angles
Correct answer option is B
3/8 yards.
1/2 is the same as 4/8, since 4 is 1/2 of 8. So, you just need to subtract 4/8 from 7/8 to find the remaining ribbon.
7/8 minus 4/8 is 3/8, so there would be 3/8 yards of ribbon remaining.

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
