-10(1/4b^2+4)
= -5/2b^2-40
Answer:
{ - 33, - 23, 2, 12 }
Step-by-step explanation:
Given
f(x) = 5x - 13 with domain { - 4, - 2, 3, 5 }
To obtain the range substitute the values of x from the domain into f(x)
f(- 4) = 5(- 4) - 13 = - 20 - 13 = - 33
f(- 2) = 5(- 2) - 13 = - 10 - 13 = - 23
f(3) = 5(3) - 13 = 15 - 13 = 2
f(5) = 5(5) - 13 = 25 - 13 = 12
Range is { - 33, - 23, 2, 12 }
1/2
Since it is asking for absolute value you just need to forget about the negative sign.
Answer:
Option a, 0.10
Step-by-step explanation:
Given that of the last 500 customers entering a supermarket, 50 have purchased a wireless phone.
i.e. out of 500 customers 50 customers purchased
Hence probability for any random customer to purchase =
Thus we find that if the relative frequency approach for assigning probabilities is used, the probability that the next customer will purchase a wireless phone is
Option a)
0.10
This is based on the assumption that the past pattern of purchase determines the probabiltiy
