Answer:
=41
Step-by-step explanation:
X = 4 and y =5
6( 
) - 
= 6 (16-5) -25
= 6 (11)-25
= 66 -25
=41
Answer:
Probability = 0.500
Step-by-step explanation:
If it is given that the reader is a teen, we have a total of 80 readers, where 40 of those readers have Rowling as their favorite.
So the probability that the reader's favorite is Rowling given that the reader is a teen is the number of teen readers that have Rowling as favorite (40) over the total number of teen readers (80)
Probability = 40 / 80 = 0.500
Answer:
one pound of banana costs $0.59
Step-by-step explanation:
Divide the cost (1.18) by the pounds (2)
1.18/2 = 0.59
Answer:
The answer is C :) (x + 1)(x-3)(x-5)
Step-by-step explanation:
In order to confirm which of the given above is an identity, what we are going to do is to check them each. By definition, an identity<span> is an equality relation A = B.
After checking each options, the answers that are considered as identities would be options C and D. So here is how we proved it. Let's take option C.
</span><span>cos^2(3x)-sin^2(3x)=cos(6x)
cos^2(3x)-sin^2(3x)=cos(2*3x)
cos^2(3x)-sin^2(3x)=cos(3x+3x)
cos^2(3x)-sin^2(3x)=cos(3x)cos(3x)-sin(3x)sin(3x)
cos^2(3x)-sin^2(3x)=cos^2(3x)-sin^2(3x)
</span>So based on this, we can conclude that <span>cos^2 3x-sin^2 3x=cos6x is an identity.
This is also the same process with option D.
Hope this answer helps.</span>
