Answer:
The smallest number is 10
Step-by-step explanation:
x+y=24---equation 1
x-y=¹/6×24=>x-y=4---equation 2
Add both equations
2x=28
x=14
put x=14 into equation 1
14+y=24
y=24-14=10
Solution :
95% confidence interval for the difference between the means of ACT scores between two schools, is given by :
![$[(\overline X_1 - \overline X_2)-ME, (\overline X_1 - \overline X_2)+ME]$](https://tex.z-dn.net/?f=%24%5B%28%5Coverline%20X_1%20-%20%5Coverline%20X_2%29-ME%2C%20%28%5Coverline%20X_1%20-%20%5Coverline%20X_2%29%2BME%5D%24)
M.E. , Margin of error,
= 9.222
s = 3.03
= 1.4
Therefore, 95% CI = [(25.90-27.70) - 1.4 , (25.90-27.70) + 1.4]
= [-3.2, -0.4]
Therefore, the lower bound is -3.2

Hello from MrBillDoesMath!
Answer: NO solution possible!
Steps:
Let "n" be the first even number. We are told that
n + (n+2) + (n+4) + (n+6) + (n +8) = 216
The third number, the value we want, is boldfaced above.
Simplify the above equation:
5n + ( 2 + 4 + 6 + 8 ) = 216 or
5n + 20 = 216 or
5n = 196
n = 196/5 is NOT an integer value. This problem, as stated, has no solution.
