Step-by-step explanation:
To find f(-6) , substitute the value of x that's - 6 into f(x). That is for every x in f(x) replace it with - 6
We have
We have the final answer as
Hope this helps you
Answer:
-10
Step-by-step explanation:
for f(-6)
we know ,
x is -6 as we are replacing value
now
f(x)=(1/2)x-7
or f(-6)=1/2*-6-7
or,f(-6)=-3-7
to therefore f(-6)= -10

Answer:
There is a 3.7% probability that they both will like it.
Step-by-step explanation:
We can solve this problem using the Bayes rule derivation from conditional probability.
Bayes rule:
What is the probability of B, given that A?
In this problem, we have that:
is the probability that Ralph likes the movie, given that Melissa likes. The problem states that this is 10%. So
is the probability that Melissa likes the movie. The problem states that .
If they randomly select a movie from a video store, what is the probability that they both will like it?
This is .
There is a 3.7% probability that they both will like it.
Answer:
There are 14 horses and 21 chickens.
Step-by-step explanation:
First, you have to make expression for horse and chicken. So we can let x be the number of horses and y will be the number of chickens. Next, given that the total number of feet for both animals is 98 so you have to make simultaneous equation :
(horse has 4 feet and chicken has 2 feet)
There are a total of 35 heads so the other equation will be :
Lastly, you have to solve it :
