63%
To express as a percentage divide 630 g by 1 Kg and multiply by 100%
note that 1 Kg = 1000 g ( units must be the same)
× 100% = 63%
The value of y is 29
Since x=4, put 4 in 9x
y = 9(4) - 7
y = 36 - 7
y = 29
The profit is calculated by subtracting the expenses from the revenue.
For Deal A:
Profit = $100,000 - $10,000
= $90,000
Deal B:
Profit = $50,000 - $20,000 = $30,000
For the percentage of revenue, we divide the revenue by the expense and multiply the quotient by 100%
Deal A: %revenue = $100,000/$10,000 x 100 = 1000%
Deal B: %revenue = $50,000/$20,000 x 100 = 250%
Answer:
The first and third quartiles were calculated incorrectly. Also, this means the inter quartile range is incorrect.
Step-by-step explanation:
The first quartile is going to be the median of the lower half of the data set {89, 93, 99, 110} this median is (93+99)/2, or 96.
The third quartile can be calculated the same way with the data set {135, 144, 152, 159} This gives us 148 as the third quartile.
Lastly, the interquartile range is just the difference between the first and third quartiles, which is 52.
