From the Figure We can Notice that :
Opposite Side - AB = 1
Adjacent Side - OB = 
We know that :
⇒ θ = 30°
We know that :
⇒ 
⇒ 
⇒ AO = 2
<span>the probability that the average of the count is more than 68 mosquitoes per square meter. assuming that the variable is normally distributed will be calculated as follows:
z=(x-</span>μ<span>)/</span>σ
where:
x=68
μ=70
σ=8
thus
z=(68-70)/8=-0.25
P(x>68)=1-P(x<68)=1-P(z<-0.25)
=1-0.4013
=0.5987
Answer: P(x>68)=0.5987
Answer:
1/12
Step-by-step explanation:
Answer:
f(x) = x(x+2)(x-4)
Step-by-step explanation:
When you set the components equal to 0, you will get your zeros.
ie. x+2=0; solving for x will get you -2 & x-4=0; solving for x gives you 4
After you expand the polynomial, you will get a degree of 3, 
Let a and b represent the fractions.
.. a +b = 3(b -a)
.. 6a -b = 3/2
Rewriting the first equation, we have
.. 4a -2b = 0
or
.. 2a -b = 0
Subtracting this from the second equation gives
.. 4a = 3/2
.. a = 3/8
.. b = 2a = 3/4
The two fractions are 3/8 and 3/4.
