X = 9/2
i hope i have helped you out. simple math for me. :)
Answer:
0.04 to the nearest hundredth.
Step-by-step explanation:
P(A and B)
= P(A ∩ B
= P(A) * P(B)
= 0.43 * 0.09
= 0.0387.
=
13. (6-9)^-3= -1/27 or -0.04(rounded to nearest hundredth.
15. 4^-1+(5-7)^-2= 1/2 or .5
Step-by-step explanation:
root 3 by 4a²

Answer:
Error = 1.167 feet
Percentage error = 0.3242%
Step-by-step explanation:
The original length of the soccer field = 120 yards long
Converting to feet
1 yard = 3 feet
120 yards = x
Cross Multiply
x = 120 × 3 feet
x = 360 feet
Measured length:
Han measures the length of the field using a 30-foot-long tape measure and gets a measurement of 358 feet, 10 inches.
We convert 10 inches to feet
1 inch = 0.0833 feet
10 inches = x feet
Cross Multiply
x = 10 × 0.0833 feet
x = 0.833 feet
The measured length = 358 feet + 0.833 feet
= 358.833 feet
The Error is calculated as:
|Measured length - Original Length)
= 360 feet - 358.833 feet
= 1.167 feet
Percentage Error
= Error/Original Length × 100
= 1.167/360 × 100
= 0.3241666667%
Approximately = 0.3242%
