Answer:
Step-by-step explanation:
sin(7y)=cos(5y+14)=sin(90-(5y+14))=sin(76-5y)
7y=76-5y
12y=76
y=76/12=19/3
or
sin(7y)=cos (5y+14)=sin (90+(5y+14))=sin (5y+104)
7y=5y+104
2y=104
y=52
Part 1-
The slope is 0
Part 2-
X=0
Part 3-
I think is D (it can’t be C)
Answer:
Therefore the correct option is a.) The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 catfish in the river.
Step-by-step explanation:
i) Let p = 0.47
ii) therefore q = 1 - 0.47 = 0.53
iii) sample size, n =25
iii) standard deviation = 
Therefore the correct option is
a.) The standard deviation is 0.0998. The 10% condition is met because it
is very likely there are more than 250 catfish in the river.
3x-5y=10
-5y=-3x+10
y=3/5x-2
There are 60 Country CDs and 136 Rock CDs.
Rock and country CDs = 196
Country CD = x
Rock CD = x + 76
Country CD + Rock CD = 196
x + (x + 76) = 196
2x = 196 - 76
2x = 120
2x / 2 = 120 / 2
x = 60 * number of Country CD
Rock CD = x + 76 = 60 + 76 = 136
To check:
Country + Rock = 196
60 + 136 = 196
196 = 196
