Answer: a) The customers surveyed purchased only mysteries =12
b) The customers purchased mysteries and science fiction, but not romance novels=10
c) The customers purchased mysteries or science fiction=46
d) The customers purchased mysteries or science fiction, but not romance novels=44
e) The customers purchased exactly two types of books=21
Step-by-step explanation:
Given: n(S)=57
n(M)=33
n(S)=25
n(R)=18
n(M∩S)=12
n(R∩M)=9
n(S∩R)=6
n(R∩S∩M)=2
From the Venn diagram,
d=2
n(M∩S)=a+d=12
⇒a=10
n(R∩M)=b+d=9
⇒b=7
n(S∩R)=c+d=6
⇒c=4
Now, the customers surveyed purchased only mysteries=n(M)-a-b-d=33-10-7-4=12
The customers purchased mysteries and science fiction, but not romance novels=a=10
The customers purchased mysteries or science fiction=n(M∪S)=n(M)+n(S)-n(M∩S)=33+25-12=46
The customers purchased mysteries or science fiction, but not romance novels=n(M∪S)-d=46-2=44
The customers purchased exactly two types of books= a+b+c=10+7+4=21
Answer:
I believe the answer is 5, because the angel/slope of the line for k being 5 is the correct angel/slope g(x) has.
HOPE THIS HELPED! HAVE A GREAT DAY! :)
We have to apply the simple interest formula:
I = p x r x t
Where :
I = interest
p = principal amount
r= interes rate ( in decimal form, percentage divided by 100)
t= time (years)
Replacing with the values given:
I = 750 x (7/100) x 3
I = 750 x 0.07 x 3
I = $157.7
Answer:
To find the exact vale of atan(-sqrt(3)) we're going to need the help of a calculator
atan(-sqrt(3)) = -1.04719755 rads.
If you take a look at the important angles, you will notice that the arc is minus 60 degrees which equals -1.04716755 radians.
