Answer:
6/5
Step-by-step explanation:
Since 68% of the sample ranges from the plus minus first standard deviation from the mean, then interval wherein it will occur will be between 53.5% to 60.5%. I got this answer through adding and subtracting one standard deviation (3.5) from the mean (which is 57).
Answer:
x = 200
Step-by-step explanation:
1/5x – 2/3y = 30
substitute in y
1/5x - 2/3(15) = 30
multiply
1/5x - 10 = 30
isolate the variable
1/5x = 40
multiply each side by 5
x = 200
The total worth of the 4 pounds and 8 ounces of box is $1800
<h3>Total cost</h3>
Weight of the boxes:
- 4 pounds
- 8 ounces
- Cost of each pound = $400
Convert ounces to pounds:
8 ounces to pounds = 0.5 pounds
Total cost of the boxes = 4 pounds (400) + 0.5 pounds (400)
= 1600 + 200
= $1,800
