Answer:
2.4 inches
Step-by-step explanation:
Actual Dimension of bedroom = 10' * 8'
In the model ; longer side = 3 inches
Length of shorter side in the model ;
Longer side of actual bedroom = 10'
Scale factor * length = model length
Scale factor * 10 = 3
Scale factor = 3/10
Hence, length of shorter side :
Scale factor * actual length of shorter side
3/10 * 8
24 / 10
= 2.4 inches

<span>The total weights must add upto 50 lbs. Let x represents the number of 3 lb weights and y represents the number of 10 lb weights, we frame an equation as 3x + 10 y =50. Because there are some 10 lb weight and some 3 lb weights but we dont know the exact number.</span>
Answer:
66
Step-by-step explanation:
The Empirical Rule states that 68% of data is between 1 standard deviation in a dataset of normal distribution, 95% falls between 2 standard deviations, and 99.7% between 3.
The mean is 450, and one standard deviation is between 450 ± 50 = 400 and 500. Therefore, we can say that 68% of the data falls between 400 and 500 seconds.
The data includes 97 emergencies, so we just need to find 68% of that, which is 0.68*97 = 65.96 (rounding up to 66)
