Answer:
I'm not sure exactly what this means, but I think I have an idea.
Fraction form: -1x > -3/2x
Decimal form: -1x > -1.5x
<em>(Again, I'm not completely sure what the question is asking for, but I think I have seen it before.)</em>
<u>Solution</u><u> </u><u>:</u><u>-</u>
Here, we have been given that lines f and g are parallel. Thus, the angle measuring 135° and ∠2 are vertically opposite angles.
And we know that vertically opposite angles measure same. Thus,
∠2 = 135°
And,
∠2 + ∠6 = 180° ( Co - interior angles sum up to 180° )
135° + ∠6 = 180°
∠6 = 180° - 135°
∠6 = 45°
Now,
we see that ∠6 and ∠5 are making a linear pair of angles, and we know that angles in a linear pair measure 180° Thus,
∠5 + 45° = 180°
∠5 = 180° - 45°
∠5 = 135°
Thus, the value of angle 5 is 135°
Hope that helps. :)
Answer:
31.77% probability the surgery is successful for exactly five patients.
Step-by-step explanation:
For each patient, there are only two possible outcomes. Either the surgery is successful, or it is not. The probability of the surgery being successful for a patient is independent of other patients. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
A surgical technique is performed on seven patients.
This means that 
You are told there is a 70% chance of success.
This means that 
Find the probability the surgery is successful for exactly five patients.
This is P(X = 5).


31.77% probability the surgery is successful for exactly five patients.
Answer:
One solution, x=1
Step-by-step explanation:
isolate the variable
Answer:
x=-2
Step-by-step explanation:
You need the standard formula
the standard formula will be
-2x²-8x+18
x=-b/2a
=-(-8)/2(-2)
=8/-4
=-2
