Answer:
34° is the closest to the record high in degree Fahrenheit ⇒ C
Step-by-step explanation:
∵ The formula F = C + 32 is used to convert the temperature from
degrees Celsius (C) to degree Fahrenheit (F)
∵ The high temperature in Chicago is 1° Celsius
→ Substitute C in the formula above by 1
∴ F = (1) + 32
∴ F = + 32
∴ F = 33.8°
→ Round it to the nearest degree Fahrenheit
∴ F ≅ 34°
∴ 34° is the closest to the record high in degree Fahrenheit
The mean, median and mode are measures of central tendency, that is they tend to indicate the location middle of the data
Required values;
(a) The performance for the week for Park Street
The performance for the week for Bridge Road
(b) The mean is <u>$3611</u>
The median is $<u>3,600</u>
The standard deviation is $<u>3250</u>
The Interquartile range is $<u>6075</u>
Reason:
The table of values that maybe used to find a solution to the question is given as follows;
(a) Park Street revenue = $7,500
Bridge Road's revenue = $7,100
The two stores sold close to but below the 75th percentile
Bridge Road revenue;
The z-score is given as follows;
From the Z-Table, we have;
The percentile= 0.7291
Park Street revenue;
The z-score is given as follows;
From the Z-Table, we have;
The percentile = <u>0.5987</u>
(b) Given that the operating cost is $3,000, frim which we have;
The subtracted value is subtracted from the mean and median to find the new value
Profit = The revenue - Cost
New mean = 6611 - 3000 = 3611
The new median = 6600 - 3000 = 3600
The standard deviation and the interquartile range remain the same, therefore, we have;
The interquartile range = 9675 - 3600 = 6075
