Assuming that this is asking for an average estimation, the mean (average) would be 50 (42+26+61+65+56) divided by 5). So your answer would be 50
The given quadratic equation is expressed as
2x^2 - 3x - 1 = 0
We would apply the general formula for quadratic equations which is expressed as
Answer:
x=7
y=2
Step-by-step explanation:
10 + 2x = -2y ➡y = -5-x
replace y with -5-x in the first equation
-5-x-x = 9➡ -2x-5 = 9 ➡-2x = 9+5 ➡ x = -7
now use this information to find value of y
y - (-7)=9 ➡y = 2
The diameter is 9 inches, so expect somewhere above triple that. 28.3 is the best approx. of what I could see.
360 mm = 36 cm
Hope that helps
