Oh this is a great question. For future reference, the formula for this would be called an exponential growth or decay function, here it Is;
Y = a( 1+r )ˣ or Y = a( 1 - r )ˣ
the answer could be found by plugging your numbers into these equations
For example:
Y = 15,250 ( 1 - .075)⁶
A value = starting value of object
R value= decimal equivalent of percent increase or decrease
x value = number of years it has been
Answer : $9552.57
Answer:
I would say A
Step-by-step explanation:
Answer:
y = - 4x
Step-by-step explanation:
Here, it is given that the slope of a line is - 4 and the y-intercept is 0.
Now, if the slope of a straight line is m and the y-axis intercept is c, the by slope-intercept form the equation of the straight line is given as
y = mx + c ......... (1)
Therefore, in our case m = - 4 and c = 0 and using equation (1), the equation of the given straight line is
y = - 4x (Answer)
Answer:
The answers to the questions are
(a) P = 0.0176
(b) P = 0.5
(c) P = 0.0571
Step-by-step explanation:
The P value is the calculated probability of obtaining extreme reults which are as extreme as observed res ult when the study null hypothesis H₀ is true
The p value is given by
P (
= 185 when μ = 175)
z = 
z(
= 185) = 
= 1.5811
Therefore the P ( = 185 when μ = 175) = P(z = 1.5811)
0.94295
The probability density function is
Therefore the probability is
= 0.0176
b) The type II error is given by
β = P(type II error) = P(Fail to reject the null hypothesis when it is false)
Therefore
β = P ( < 185 when μ = 185)
P
, which gives
P(z<0) and β = 0.5
(c) For true mean foam height of 195 mm we have
β = P ( < 185 when μ = 195)
and P
Which gives P(z < -1.58)
From z table the probability is β = 0.0571
