HELP A Folgers Black Silk K-Cup coffee pod weigh on average .28 oz with a standard deviation of .05 Oz answer to the questions.
1.) what percentage of K-cups can be expected to fall within two standard deviations of the mean?
2.) what is the probability that a K-Cup will have more than three .33 oz?
3.) K-Cups that are more than two standard deviations below the mean are considered to be weak. What percentage of K-Cup are considered to be weak?
4 ) in a standard box of 44 K Cups, how many will weigh between .23 and .38 Oz?
5.? Sam's Club sells K-Cups in a box of 128. How many of them will weigh less than 23 Oz?
6.) the ideal weight for K-Cups are within one standard deviation of the mean, how many of the Sam's Clubs box of K-cups are ideal?

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.

the rate of change is 25
