Answer:
The probability that it would take more than four hours to construct a soapbox derby car = 0.1587 or 15.87
Step-by-step explanation:
Given -
Mean = 3 hours
Standard deviation = 1 hours
Let X be the no of hours to construct a soapbox derby car
the probability that it would take more than four hours to construct a soapbox derby car =
=
= Put
= 1 -
= 1 - .8413 Using z table
= 0.1587
Answer:
P(t) = 282.2(1.009)^t
Step-by-step explanation:
Look at the attached image.
Hope you can read my handwriting. the image cut off the right side, b = 1.009213324... but question asks to round to nearest thousandth so it's 1.009
For the second part just use the equation to find P when t = -1 and see if P is less than (underpredicts) the number from the question or greater than (overpredicts) the number. I haven't calculated it but I think it will be smaller and thus underpredicts just from looking at the numbers when t = -1
The given equation is equivalent to the expression -3c.
Given that, the expression can be written as.
By simplifying the above equation,
By taking out the common terms from the equation,
By simplifying the above equation by cancel out the common factors.
Now, by taking (-1) common from (-2c+1) we get,
By simplifying the above equation, we get the expression,
So the given equation is equivalent to the expression -3c.
