one of the results is randomly selected, what is the probability that it is a false negative (test
indicates the person does not have the disease when in fact they do)? What does this probability
suggest about the accuracy of the test?
A) 0.591, The probability of this error is high so the test is not very accurate.
B) 0.0348, The probability of this error is low so the test is fairly accurate.
C) 0.0134; The probability of this error is low so the test is fairly accurate.
D) 0.0369; The probability of this error is low so the test is fairly accurate.

it has the same slope and a different y-intercept

hope this : )

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

sorry

step-by-step explanation:

sorry, but im pretty sure its a now that i look at it
