Answer:
11=0
or
-11=0
keep in mind that you get these answers by completely simplifying the equation, but they are both false
Step-by-step explanation:
step 1: simplify both sides
2-16.5 simplifies to -14.5
4-7.5 simplifies to -3.5
so you get -3.5 = -14.5
step 2: add one side to the other to get a zero on one side
add 3.5 on both sides to get 0=-11
or
add 14.5 on both sides to get 11=0
step 3: evaluate the statement
since both -11 and 11 are not equal to 0, this statement is false
Answer:
0.0713 = 7.13% probability that the result is positive.
Step-by-step explanation:
Probability of a positive test:
91% of 1/650(has the disease).
7% of 1 - 1/650 = 649/650(does not have the disease). So
0.0713 = 7.13% probability that the result is positive.
Answer:
7
Step-by-step explanation:
Multiply by 3 in the first equation and then you can cancel out the +3y and -3y to get the x answer. After that, you can do the same with the y by multiplying -2 in the first equation to cancel out the +2x and the -2x. Do you understand?
