Answer:
And we can find this probability with the complement rule and with the normal standard table and we got:
Step-by-step explanation:
Let X the random variable that represent the patient recovery time of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And we can solve this problem using the z score formula given by:
And using this formula we got:
And we can find this probability with the complement rule and with the normal standard table and we got:
Start by getting one of the equations in terms of one variable, in this case lets put the first equation in terms of y
2x+y=3 ---> y=3-2x
now we plug that into the second equation
5x-2y=12 ---> 5x-2(3-2x)=12
we can then multiply and simplify
5x-2(3-2x)=12 ---> 5x-6+4x=12 ---> 9x-6=12 ---> 9x=18 ---> x=2
we can now plug x=2 into an equation to solve for y
2(2)+y=3 ---> 4+y=3 ---> y=-1
Answer:
B. (0 , 0)
Step-by-step explanation:
Plug in the coordinate into the equation given.
Note that:
x = x
f(x) = y
Also note that in B, x = 0, y = 0
Plug in the corresponding number with the corresponding variable
0 = 5^(0)
Simplify
5^0 = 0
0 = 0 (True)
B. (0 , 0) is your answer
