Answer:
B: 3/4
Step-by-step explanation:
Since we know this is an exponential function
y= ab^x
where a is the initial value and b is the growth rate or what we multiply by
For the first point x=1 and y = 3/2
3/2 = a b^1
3/2 = a*b
For the second point x=2 and y = 9/8
9/8 = a b^2
Take the second equation over the first
9/8 = a b^2
-------------------
3/2 = a*b
3/4 = b
The growth rate is 3/4
That would also be know as the rate of change
Answer:
P(X > 126) = 0.2119
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
P(X > 126) is the 1 subtracted by the pvalue of Z when X = 126. So
[tez]Z = 0.8[/tex]
[tez]Z = 0.8[/tex] has a pvalue of 0.7881.
P(X > 126) = 1 - 0.7881 = 0.2119

Answer:
Amount received by Aman's Wife = $4000
The expression which shows the amount received by his son = x+ 10000
Step-by-step explanation:
The total amount Aman has = $9000
Let us assume the amount his daughter receives = $x
So, the amount his wife received = 2 x (Amount received by Daughter)
= 2 x ($x) = 2 x
And the amount his son received =$1000 + (Amount received by Daughter)
= 1000 x ($x) = x+ 10000
According to the question:
Amount of ( Daughter's + Wife's + Son's) share = $9000
x + 2x + x + 10000 = $9,000
⇒4 x = 9000 - 1000
or, 4 x = 8000
⇒ x = 8000 / 4 = 2,000
⇒ x = $2,000
So, the amount received by Aman's Wife = 2 x + 2 ($2000) = $4000
The expression which shows the amount received by his son = x+ 10000
