Step-by-step explanation:
Hello!
Be X: air pressures of properly inflated sports balls.
<em>Average recommended psi Tolerance(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: 72
Step-by-step explanation:
6 * 2 = 12
12 / 2 = 6
6 * 2 = 12
12 / 2 = 6
6 * 10 = 60
60 / 2 = 30
6 * 10 = 60
60 / 2 = 30
30 + 30 + 6 + 6 = 72
Answer:
B. x = 5 and y = -13
Step-by-step explanation:
Subtract the constant on the left:
... (x +yi) = (9 -4i) -(4 +9i)
... = (9 -4 +i(-4-9))
... = 5 -13i
Matching real and imaginary parts, we see that ...
... x = 5, y = -13
The number 5 divided by 2 is 2 with a remainder of 1 (5 / 2 = 2 R. 1). This is also written as 5 /2 = 2.5. I hope this can help you get your answer sorry if it’s not good
