(A) because it is reflecting over the x-axis.
Answer:
n=2
Step-by-step explanation:
Simplify.
6−3(n−2)=8−n
6+(−3)(n)+(−3)(−2)=8+−n(Distribute)
6+−3n+6=8+−n
(−3n)+(6+6)=−n+8(Combine Like Terms)
−3n+12=−n+8
−3n+12=−n+8
Add n to both sides.
−3n+12+n=−n+8+n
−2n+12=8
Subtract 12 from both sides.
−2n+12−12=8−12
−2n=−4
Divide both sides by -2.
-2n/-2 = -4/-2
n=2
Answer:
Order from least to greatest
Step-by-step explanation:
1.6
2/3=0.66666 or 0.67
0.5
3/2=1.5
2.5
Order from least to greatest would be 0.5,0.67,1.5, 1.6, 2.5

(x + 3)(2x - 1) = x(2x - 1) + 3(2x - 1) = 2x^2 - x + 6x - 3 = 2x^2 + 5x - 3
Answer:
a) Mean = 382.3 psi
Standard deviation = 20.8 psi
b) 392.7 psi
c) P(X<400)=0.8026
Step-by-step explanation:
a) The population mean can be estimated as equal to the mean of the sample, and the population standard deviation can be estimated from the sample standard deviation:


b) We start by searching for the z-value for the 95th percentile. This value is
z=1.645:

Then, the strength value below which 95% of all welds will have their strengths is:

c) We calculate the probability of X being equal or less than 400 as:
