No, Mike presented the ratio based on the change compared to the new amount. He ought to have utilized the ratio of the change against the original amount, which is represented as 55/275, or 20%.
Answer: $3
Step-by-step explanation: I confirmed the diagnostic, and it was accurate
The correct response is D; we can treat the survey as one involving a single variable, responding with either "yes, I attended more than 4 games" or "no." Given the random survey of 10 students meets the randomization criterion and that their responses are independent, options B and C can be dismissed. However, since only 10 students were surveyed, the confidence interval will not be narrow. As per Statistical Solutions, a minimum of 10 subjects per variable is essential for regression analysis. If the query concerns the number of games each student attended, the potential variables increase; conversely, if it solely asks, “Did you attend more than 4 games?”, then we only consider a single variable, making 10 students sufficient.
Answer: Macy's pre-tax shirt price is $5.63
Step-by-step explanation:
Details:
Original cost = 20
sale price drops by 25% every month it remains unsold.
First markdown month:
20 * (100%-25%) = 20 * 75% = 15
Second markdown month:
15 * 75% = 11.25
Macy, being an employee, enjoys a 50% discount on the current price.
11.25 * 50% = 5.625
11.25 - 5.625 = 5.625 or rounded to 5.63
Hope this helps!:)
The attached graph shows the moment when his catch surfaced at (35, 0). Given that it ascends consistently, the graph is linear. We need to establish the starting depth before he reeled it in. Using the equation d=rt, where d represents depth, r is the speed, and t is the time, we can find the distance traveled to reach the surface. Setting up the equation yields: d = 0.1(35). This indicates the catch traveled 3.5 m from a starting point of 3.5 m underwater, ascending at a rate of 0.1 m per second.
