Step-by-step explanation:

FULL QUESTION:

A certain brand of candies have a mean weight of 0.8605 g and a standard deviation of 0.0513. A sample of these candies came from a package containing 441 candies, and the package label stated that the net weight is 376.7 g. (If every package has 441 candies, the mean weight of the candies must exceed 376.7/441 =0.8543 g for the net contents to weigh at least 376.7 g.)

a. If 1 candy is randomly selected, find the probability that it weighs more than 0.8543 g.

The probability is ?. (Round to four decimal places as needed.)

b. If 441 candies are randomly selected, find the probability that their mean weight is at least 0.8543 g.

The probability that a sample of 441 candies will have a mean of 0.8543 g or greater is ?. (Round to four decimal places as needed.)

c. Given these results, does it seem that the candy company is providing consumers with the amount claimed on the label?

Yes/no because the probability of getting a sample mean of 0.8543 g or greater when 441 candies are selected is /is not exceptionally small.

SOLUTION:

For part a) we need to calculate a z-score and refer to the normal distribution tables.

Remember that not all distribution tables read the same way, but they should show you by a diagram whether the percentage given is for the area to the left of the z or to the right.

Z = (X - μ)/σ or Z = (.8543 - .8605)/.0513 = -.1209

The area to the right of this Z-score translates to a probability of 0.5478

Part b) is essentially the same calculation but with a sample standard deviation:

σx = σ/√n = .0513/√(441) = .0024

Z = (.8543 - .8605)/.0024 = -2.5833

The area to the right of this Z-score translates to a probability of 0.9951

c) Yes, because the probability of getting a sample mean of 0.8543 or greater when 441 candies are selected is NOT exceptionally small.

Ten pictures, each measuring 4 inches by 6 inches, are mounted on a piece of green poster board so that there is no overlap. The
alexandr1967 [171]

Answer:

100 square inches

Step-by-step explanation:

Dimension of each of the ten pictures= 4 inches by 6 inches

Area of one of the pictures=4*6=24 Square Inch.

Total Area of the 10 pictures=24*10=240 Square Inches.

Dimension of the Poster Board=20 inches by 17 inches.

Area of the Poster Board=20*17=340 Square Inches.

Area not covered by the pictures=340-240=100 Square Inches

Therefore, 100 square inches of the green background will show after the pictures are mounted.

How do I solve: 15 - w/4 = 28 (this is 2 step equations)
kenny6666 [7]
First we need to isolate the variable so we add 15 to both sides which is
w/4=43  then we need to multiply by 4 to both sides so its 4w=172
then divide by 4 which is 43 so the answer is w=43
