Answer:
Step-by-step explanation:
Triangle GEF is a right angle triangle.
From the given right angle triangle
GE represents the hypotenuse of the right angle triangle.
With ∠E as the reference angle,
FE represents the adjacent side of the right angle triangle.
FG represents the opposite side of the right angle triangle.
To determine tan E, we would apply the tangent trigonometric ratio
Tan θ = opposite side/adjacent side. Therefore,
Tan E = 56/33
Tan E = 1.69697
It becomes 1.70 to the nearest hundredth.
Answer:
The parameters of this exponential distribution is
=
.
Step-by-step explanation:
We are given that the random variable X is known to be exponentially distributed and let X be the time it takes for a person to choose a birthday gift, where X has an average value of 27 minutes.
<u><em>So, X = time it takes for a person to choose a birthday gift</em></u>
The probability distribution function of exponential distribution is given by;
where,
= parameter of distribution.
Now, the mean of exponential distribution is =
which is given to us as average value of 27 minutes that means
.
So, X ~ Exp(
) .
Therefore, the parameter of this exponential distribution is
.
40s=360+30a
40s+30a=$3960
40s=360+30a
40s/40=360+30a/40
s = 9+3/4a
40(9+3/4a) +30a=$3960
360+30a+30a=$3960
360+60a=$3960
360-360+60a=$3960
60a=$3960
60a/60 = $3960/60
a= $60
The algebra book is $60
The answer is 2/5. Divide both the numerator and denominator by 7. :)
