Answer:
55
Step-by-step explanation:
angle BHE=JHI=80(vertically oposite)
ABC=EBH=45(vertically opposite)
Sum of interior angles of triangle EBH is 180
==> 45+80+BHE=180
125+BHE=180
BHE=180-125
BHE=55
Answer:
Step-by-step explanation:
Step1: isolate the square root on the left hand side.
Original equation :x+1=√-6x-6
Isolate :x+1=√-6x-6.
Step2: raise both sides to the second power.
(x+1)^2=(√-6x-6)^2
(x+1)(x+1)=-6x-6
Step3: after squaring, solve the quadratic equation.
x^2+2x-1=-6x-6
x^2+8x+7=0
x^2+7x+x+7=0
x(x+7)+1(x+7)=0
(x+1)(x+7)=0
x=-1,-7
Step4:check that the first solution correct.
Input x=-1 into the original equation
x+1=√-6x-6
-1+1=√+6-6
0=0
Step5:check that the second equation is correct.
Input x=-7 into the original equation
x+1=√-6x-6
-7+1=√42-6
-6=√36
-6#6
Therefore one solution is found.
x=-1

Determine the probability that a selected individual who has the disease test negative.
This type of probability is referred to as conditional probability.
First, we need to get the number of individuals who have the disease.
Next, we list out the number of individual who have the disease but is negative.
The probability is then calculated as:
