Answer: 130 shark cookies.
Step-by-step explanation: If you divided 170 clown fidh cookies by 85 clown fish cookies you get 2. So same as 85 times 2. Then do the same with the shark cookies. 65 times 2, that equals 130.
Answer: 0.98
Step-by-step explanation:
Let J denotes Jungle Cruise , M denotes Monorail and H denotes Matterhorn.
As per given ,
P(J) = 0.74, P(M) = 0.62, P(H) = 0.70
P(J∩M) = 0.52, P(J∩H)= 0.46 , P(M∩H)=0.44
P(J∩M∩H)=0.34
Now , the required probability:
P(J∪M∪H) = P(J) + P(M) + P(H) - P(J∩M) - P(J∩H) - P(M∩H)+ P(J∩M∩H)
= 0.74+0.62+0.70-0.52-0.46-0.44+0.34
= 0.98
Hence, the probability that a person visiting Disneyland will go on at least one of these three rides= 0.98 .
Answer:
A company produces electric insulators. The strength of the insulators is important since a broken insulator may cause a short circuit. Unfortunately, the strength varies significantly due to the material. Because of the expense, only a limited number of insulators could be tested. The engineers sampled 25 insulators (From a production run of 200), and conducted a destructive test to determine the force that was required to break the insulators. The mean value of this force was 1723 lbf with a sample standard deviation of 90 lbf. You may approximate the population standard deviation with the sample standard deviation for the following questions. a. Determine if the population is large enough or if a finite population correction (FPC) factor is needed. If so, what is the FPC factor? b. For 95% confidence, determine the margin of error (+ lbf) c. For these conditions, estimate the range of the probable population mean. Provide lower and upper values. For 95% confidence, determine the margin of error ( Assume the same mean and sample standard deviation. What is one advantage and one disadvantage of using 50 insulators instead of 25 insulators? d. lbf) if 50 insulators were tested.

Answer:
The points on a line can be assigned real number coordinates (think of numbers on a number line). The distance between any two points is their difference.
The factored form of 20x+35y would be 5(4x+7y). If you use the distributive property of multiplication, you can see that the expression has not changed.
