Answer: 25
Step-by-step explanation: -5 x 25 + 13 = -112
Answer:
45
Step-by-step explanation:
Given
3z² - 6z ← substitute z = 5 into the expression
= 3(5)² - 6(5)
= 3(25) - 30
= 75 - 30
= 45
Answer:
And we can find this probability to find the answer:
And using the normal standar table or excel we got:
Step-by-step explanation:
Let X the random variable that represent the amounts of nocatine of a population, and for this case we know the distribution for X is given by:
Where 
and 
We have the following info from a sample of n =37:
the sample mean
And we want to find the following probability:
And we can use the z score formula given by;
And if we find the z score for the value of 0.872 we got:
And we can find this probability to find the answer:
And using the normal standar table or excel we got:
Answer:
x cannot be -4,-3, or 13
x can be anything else
Step-by-step explanation:
There are infinitely many values x can take where the relation above will be a function.
For it to be a function, you just need to make sure each x is only assigned one y value.
So x couldn't be -4 because it would by assigned to y=2 and y=0.
x couldn't be -3 because it would be assigned to y=1 and y=0.
x couldn't be 13 because it would be assigned to y=5 and y=0.
So as long as x is not chosen to be -4,-3, or 13 your relation here is a function.
