Answer:
The percent error in his calculation is 5.26%.
Step-by-step explanation:
Percent error:
Number of misses multiplied by 100 and divided by the correct value.
In this question:
Total of 72 + 4 = 76 people. 4 were missed, so:
The percent error in his calculation is 5.26%.
-7x+14>-3x-6
Add 3x to both sides
-7x+14+3x>-3x-6+3x
-4x+14>-6
Subtract 14 from both sides
-4x+14-14>-6-14
-4x>-20
Divide both sides by -4
-4x/4>-20/-4
x<5
I hope that's help , please let me know !
No. Round 146 to 150 and add both 270 and 150. It's 420. So 400 would be more reasonable. 300 is not reasonable because it ain't close.
The associated z score for filling to 10.98 oz. is -1.16.
<h3>
Z score</h3>
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ) / σ
where x is the raw score, μ is the mean and σ is the standard deviation.
Given that μ = 12.01, σ = 0.89, hence:
For x = 10.98:
z = (10.98 - 12.01)/0.89 = -1.16
The associated z score for filling to 10.98 oz. is -1.16.
