The yearly wheat yield per acre on a farm is normally distributed withμ=35bushels and the standard deviation σ=8 bushels. (a) Draw a normal curve and shade the area under the curve that represents the probability that an acre will yield between 19 and 35 bushels. (b) Is the area the same as the area between μ-2σ and μ? (c) Find the percentage of area over the interval between 19 bushels and 35 bushels. (d) What is the probability that the yield will be between 19 and 35 bushels per bushel?

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

can you put the picture up?

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
