Answer: a) 83, b) 28, c) 14, d) 28.
Step-by-step explanation:
Since we have given that
n(B) = 69
n(Br)=90
n(C)=59
n(B∩Br)=28
n(B∩C)=20
n(Br∩C)=24
n(B∩Br∩C)=10
a) How many of the 269 college students do not like any of these three vegetables?
n(B∪Br∪C)=n(B)+n(Br)+n(C)-n(B∩Br)-n(B∩C)-n(Br∩C)+n(B∩Br∩C)
n(B∪Br∪C)=
So, n(B∪Br∪C)'=269-n(B∪Br∪C)=269-156=83
b) How many like broccoli only?
n(only Br)=n(Br) -(n(B∩Br)+n(Br∩C)+n(B∩Br∩C))
n(only Br)=
c) How many like broccoli AND cauliflower but not Brussels sprouts?
n(Br∩C-B)=n(Br∩C)-n(B∩Br∩C)
n(Br∩C-B)=
d) How many like neither Brussels sprouts nor cauliflower?
n(B'∪C')=n(only Br)= 28
Hence, a) 83, b) 28, c) 14, d) 28.
If we place what the husband earns as h and what the wife earns as w, we can begin...
w + h = 110000
but w = 2h - 16000
We can turn it into..
2h - 16000 + h = 110000
Which we can then combine into..
3h - 16000 = 110000
Add 16000 and..
3h = 126000
Divide by three...
h = 42000
(nice)
The husband earns 42,000$ a year
Bonus: The wife then earns 68,000$
42,000 (or h) + 68,000 (or w) = 110,000
Because this is the original equation, we are correct.
Answer:
Step-by-step explanation:
for horizontal line slope m=0
eq. of horizontal line at (0,7) with slope 0 is
y-7=0(x-0)
y-7=0
or
y=7
slope of vertical line=∝
eq of vertical line through (0,7) is
y-7=∝(x-0)
or
x-0=0(y-7)
x-0=0
or
x=0
Answer:
march 9
Step-by-step explanation:
10+3-4
=9
I think that's the answer
Use distanc formula
distance betwen ponts (x1,y1) and (x2,y2) is
D=
distance from art to gass is
from (6,1) to (4,4)
input to find
D=
=√13
distance from cemetary to animal is
from (3,-4) to (6,-2)
D=
=√13
how does √13 compare with√13
they are equal
compare dissacne betwen police and stadium then police and art
police to stadium is
(0,-4) to (-2,3)
D=
=√53= aprox 7.28011
police to art is
(0,-4) to (6,1)
D=
=√61= aprox 7.81025
from police to art is longer by (7.81025-7.28011=0.53015) 0.53015 units
