Step-by-step explanation:
Hello!
The variable of interest is
X: air pressures of properly inflated sports balls.
<em>Average recommended psi Tolerance
</em>
<em>(pounds per square inch)
</em>
<em>Soccer ball 12.05
±3.55
</em>
<em>Basketball 8.00
±0.5 </em>
<em>Volleyball 4.44
±0.18</em>
Each recommendation is expressed like the "average air pressure" ± "standard deviation of the recommended air pressure" so if you express it in inequality it will be:
X[bar]-S ≤ X ≤ X[bar]+S
So for each ball type, you can write it as:
<u>Soccer ball</u>
12.05-3.55 ≤ X ≤ 12.05+3.55
8.5 ≤ X ≤ 15.6
<u>Basketball</u>
8.00-0.5 ≤ X ≤ 8.00+0.5
7.5 ≤ X ≤ 8.5
<u>Volleyball</u>
4.44-0.18 ≤ X ≤ 4.44+0.18
4.26 ≤ X ≤ 4.62
I hope this helps!

Answer:
Step-by-step explanation:
The area is the product of the length and width
- The area = 7 1/6 m² = 43/6 m²
- The length = 3 1/3 m = 10/3 m
Width = ?
- A = lw
- w = A/l
- w = 43/6 ÷ 10/3 = 43/6 × 3/10 = 43/20 = 2 3/20 m
The width is 2 3/20 m
I did not even understand that equation
