Answer: 0.382 ounces
Step-by-step explanation:
To find the unit rate of the weight of a single cookie, we will use division.
19.1 ounces per bag / 50 cookies in the bag = 0.382 ounces per cookie
To check our work, we will multiply 0.382 ounces per cookie by 50. Since the bag, with 50 cookies, weighs 19.1 ounces, 0.382 times 50 should equal about 19.1 ounces.
0.382 ounces * 50 cookies = 19.1 ounces ✓
Answer:
a) The expected value and the variance for the amount that the bank loses on a typical roll is 0.36
b) The probability that the bank will lose at least 25 cents in 100 rolls is 0.2033
c) The probability that the bank will lose any money in 100 rolls is 0.9995
d) The rolls bank need to collect to have a 99 percent chance of a net loss are 50 rolls.
Step-by-step explanation:
Detailed steps are attached below
f(x) = 7x - 1
-2 = 7x - 1
-2 + 1 = 7x
-1 = 7x
x = -1/7
0 = 7x - 1
1 = 7x
x = 1/7
4 = 7x - 1
4 + 1 = 7x
5 = 7x
x = 5/7
8 = 7x - 1
8 + 1 = 7x
9 = 7x
x = 9/7
So the domain is
Domain = {-1/7, 1/7, 5/7, 9/7}

x2-6x-7=2
(x2-6x-7)+7=2+7 -6x+x2+7. 6x+x2=9
