Answer: D) randomized comparative design
Step-by-step explanation:
A randomized comparative design involves comparing two or more treatments and is characterized by an experiment intended to highlight differences between two groups or populations subjected to distinct conditions or treatments. In the scenario described, pre-existing data was juxtaposed with information collected after the alcohol dangers course.
(a) The likelihood that all 5 eggs chosen are unspoiled is 0.0531. (b) The probability that 2 or fewer out of the 5 eggs are unspoiled is 0.3959. (c) The probability that more than 1 of the selected 5 eggs are unspoiled is 0.8747. Step-by-step explanation: The complete query is: A subpar carton of 18 eggs has 8 that are spoiled. An unsuspecting chef selects 5 eggs at random for his “Mega-Omelet Surprise.” Calculate the probability of receiving (a) exactly 5 unspoiled eggs, (b) 2 or fewer, and (c) more than 1 unspoiled egg. Define X = number of unspoiled eggs. In the faulty carton, 8 eggs are spoiled. The probability of selecting an unspoiled egg is independent of others. Provided that a chef randomly picks 5 eggs, the variable X follows a Binomial distribution with parameters n = 5 and p = 0.556. Success is defined as selecting an unspoiled egg. The probability mass function of X is as follows: (a) Calculate the probability of selecting all unspoiled eggs. Thus, this probability is found to be 0.0531. (b) For 2 or less unspoiled eggs, the probability is computed: P (X ≤ 2) = P (X = 0) + P (X = 1) + P (X = 2), resulting in a probability of 0.3959. (c) For more than 1 unspoiled egg: P (X > 1) = 1 - P (X ≤ 1), yields a final probability of 0.8747.
Response: It will require him 1 hour and 35 minutes
Answer:
7/24
Step-by-step explanation:
All the items being grilled collectively equal 1.
Each item represents a fractional portion of 1.
Combine 3/8 and 1/3, then subtract that sum from 1.
3/8 + 1/3 = 9/24 + 8/24 = 17/24
This means that veggie burgers and corn contribute to 17/24 of the total.
To determine the fraction accounted for by mushrooms, we take 1 and subtract 17/24.
1 - 17/24 = 24/24 - 17/24 = 7/24.
Final answer: 7/24
Answer:
Base Charge = $7
Additional Fees = $7
Step-by-step explanation:
Let x represent the base charge and y for the additional fees.
For a job that lasts 5 hours, we obtain:
For the 3-hour task
Finding x and y;
Deduct the second equation from the first
Calculate y
Replace 7 with y in the first equation
