<span>each question is worth 4 points because if he missed 5 questions and 5*4 is 20 and 20 minus 100 is 80

Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
True mean(μ) = 77.9
True standard = 20
Sample size (n) = 50
Sample mean (m) = 82.1
Sample standard deviation (s) = 18.6
The standard error (SE) :
SE = sample standard deviation / √sample size
SE = 18.6 / √50
SE = 2.6304372
SE = 2.63
Answer:
square inches per seconds.
Step-by-step explanation:
given that a rectangle is growing such that the length of a rectangle is 5t+4 and its height is √t, where t is time in seconds and the dimensions are in inches
Area of rectangle = length * width
A =
To find rate of change of A with respect to t, we can find derivative of A with respect to t.
WE get
Hence rate of change of area with respect to time is
square inches per seconds.
Answer:
Step-by-step explanation:
The question concerns the use of inequalities in correct mathematical language.
When we have the condition "at least", it means something is greater than and equal; when we have the condition "at most", it is lesser than and equal.
In this case, we must use the former condition. Let's denote age with the letter a.
Then, the correct inequality is going to be:
Using the chain rule.
<span><span>sin^3</span>(x) = [sin(x)<span>]^3
</span></span><span><span>d/<span>dx</span></span>[sin(x)<span>]^3</span>∗<span>d/<span>dx</span></span>[sin(x)]
</span>d/dx sinx = cosx
d/dx<span> cosx = -sinx </span>
d/dx<span> (-sinx) = -cosx </span>
d/dx <span>(-cosx) = sinx
back to where we started from!!! </span>
So,
repeat repeat repeat !!
