Step-by-step explanation:
If f(x)=3x+2and g(x)=x^2-9
find (f-g)(x)
f(x)- g(x) = [3x + 2] - [x^2 - 9]
= -x^2 + 3x + 11
Answer: 0.01145
Step-by-step explanation:
We use Binomial distribution , where the probability of getting x successes in n trial is given by :-
, p = probability of getting each success in each trial.
As per given
The proportion that a car with a certain protection system will be recovered= p=0.87
n= 8
Let x be the number of cars will be recovered.
Then, the probability that 4 of 8 stolen cars will be recovered:
Hence, the required probability is 0.01145.
Answer:
Yes, it is true that is a factor of .
Step-by-step explanation:
Let us try to factorize
Let us try to make a whole square of the given terms:
--------------
Formula used above:
In the above equation, we had .
--------------
Further solving the above equation, taking common out of
Taking common out of the above term:
So, the two factors are .
The statement that is a factor of is <em>True.</em>
If each bag covers 1.25 ft^2 then you need to divide the total area 60 ft^2 by 1.25 ft^2 and that will tell you the number of bags needed which is 48 bags
Y=2 7x2= 14
X= 7 4x7=28
28-14=14
