3. A. y=1/x
Step-by-step explanation:
too long to give te explanations but they're there in the attachments
The function is decreasing from -6 to -3, that is, on the interval (-6,-3), and again on the interval (1, infinity).
The function is increasing on (-3,1).
No local or absolute minimum.
(1,4) is an absolute max.
Answer:
8
Step-by-step explanation:
f(1) is another notation for x = 1
so we’ll plug in 1 for x
f(1) = 7((1) -1) +8
f(1) = 7(0) +8
f(1) = 0 +8
f(1) = 8
Answer:
Step-by-step explanation:
a) The two populations were i) the pregnant mothers who took the drug ii) the pregnant mothers who did not take the drugs
b) The data must have been obtained in a survey because experiment was not done.

Hence out of 1000 abnormalities estimated = 
i.e. approximately 16
d) Mothers who did not take drug
(information incomplete)
e) Medical hypothesis testing requires accurate results and hence sample sizes should be very large.
Answer:
The subset of rational numbers
Step-by-step explanation:
Rational numbers are numbers that can be expressed in the form a/b where ad b are integers. The number
is a number with a recurring decimal of 5 and every recurring decimal can be expressed in the form a/b where a and b are both integers therefore, every number with recurring decimal is a rational number.
In the question,
can be written as follows;
or
