Answer:

Step-by-step explanation:
the ratio of hypotenuse to longer leg of 30-60-90 triangle is 1 to sqrt(3)/2, and multiply by 7 to obtain answer
5-6x=2+7x
+6x +6x
5=2+13x
-2 -2
3=13x
3/3= 13/3
x=4.33
Answer:
0.0224 or 2.24%
Step-by-step explanation:
The probability that an intern uses drugs, given that the test is negative, is determined by the probability of false negative divided by the probability of a negative (true or false).
A false negative occurs when an intern who uses drugs (10%) takes the test and gets a negative. Since the test gets it right 80% of the time, the probability of this happening is:

A true negative occurs when an intern who does not use drugs (90%) takes the test and gets a negative. Since the test gets it wrong 3% of the time, the probability of this happening is:

Therefore, the probability that an intern uses drugs, given that the test is negative is:

The probability is 0.0224 or 2.24%.
Answer:
Ok that's not it
x=-1 then y=4
x=0 then y= 6
x=1 then y = 8
x=2 then y= 10
x=3 then y= 12
Step-by-step explanation:
when y=2x+6
you have to plug what it says x is in each of the equations.
For the first one it says x=-1
you then plug that in and you get y=2(-1)+6
then you go through PEMDAS and first you get y=-2+6
-2+6 = 4
therefore y=4
and you just go through the rest wiht that

Determine the true statement about b
The question is incomplete as options are not given. However, a general explanation is as follows:
Rewrite 

When a = 0

When a = 1

This means that:
For 
Then 
<em>This means that: b is a number between 0 and 8</em>
