If <em>y</em> = cos(√<em>x</em>), then by the chain rule
d<em>y</em>/d<em>x</em> = d/d<em>x</em> [cos(√<em>x</em>)]
d<em>y</em>/d<em>x</em> = - sin(√<em>x</em>) d/d<em>x</em> [√<em>x</em>]
d<em>y</em>/d<em>x</em> = - sin(√<em>x</em>) (1 / (2√<em>x</em>))
d<em>y</em>/d<em>x</em> = - 1/2 sin(√<em>x</em>) / √<em>x</em>
Answer:
44?.. im going to get rhis one wrong
A: 450. 1,350-1,200=150 x 3=450.
B: I'm not sure how to make a slope intercept graph... :(
Answer: 0.9746
Step-by-step explanation:
Given : A normally distributed population has a mean of 250 pounds and a standard deviation of 10 pounds.
i.e.

Sample size : n= 20
Let
sample mean values.
Then, the probability that this sample will have a mean value between 245 and 255 be

Hence , the probability that this sample will have a mean value between 245 and 255 is 0.9746 .
1. 25 - 3x
Then solve for x
