Step-by-step explanation:
x = Iman's money
y = Daphne's money
x = 2y
x - 128 = y - 40
now we use the first equation as identity in the second equation and get
2y - 128 = y - 40
y - 128 = -40
y = $88
x = 2y = $176
these were the starting values.
now, after spending, they have both left
176 - 128 = 88 - 40 = $48
Answer:
The value of the parameter is λ is 0.03553357
Step-by-step explanation:
Consider the provided function.
for −∞ < x < ∞.
It is given that standard deviation is given as 39.8 km.
Now we need to calculate the value of parameter λ.
The general formula for the probability density function of the double exponential distribution is:
Where μ is the location parameter and β is the scale parameter.
Compare the provided equation with the above formula we get.
and μ = 0.
Standard deviation = √2β
Now substitute the value of β in .
Hence, the value of the parameter is λ is 0.03553357
Answer: A) segment MN ≡ segment QPIf two triangles are congruent, they have corresponding sides and corresponding angles congruent.
In order to find which are the corresponding sides, you need to be careful about the order of the letters, and therefore of the vertices (see picture attached).
From the congruency, we can say:
∠M ≡ ∠P
∠N ≡ ∠Q (statement B)
∠O ≡ ∠R (statement D)
MN ≡ PQ
NO ≡ QR (statement C)
OM ≡ RP
Hence, the only statement which is not true is <span>
A) segment MN ≡ segment QP.</span>
Answer:
Step-by-step explanation:
you multily the negative by the positive and get a negative answer so -36.8
Answer: 145
Step-by-step explanation:
you have to find what x is based on the other side
4x+15+30x-5=180
x=5
plug in 5 in 20x+45
which equals 145
