The t-statistics that will ba calculated from the data about the steel housing will be -5.936.
<h3>How to calculate t-statistic?</h3>
From the information given, the component part of the housing is a steel trough that is made out of a 14-gauge steel coil.
From the complete question that has the data, the t-statistic will be calculated thus:
u = 8.46
x bar = 8.422
s = 0.04
n = 49
Therefore, the t-statistics will be:
= (8.421 - 8.46) / (0.046 / ✓49)
= -5.936
In conclusion, the t-statistics is -5.936.

Answer:
4y = 26
Explanation:
Given the system of equations:
2y-x=-7 (1)
x+2y= 33 (2)
To find the ordered pair (x, y) that satisfies the equation, we have to solve equations 1 and equations 2 simultaneously, finding the value of x and y as our solution.
Solving equation 1 and equation 2 simultaneously: To find y add both equations together to get:
4y = 26
Divide both sides by 4
4y/4 = 26/4
y = 6.5
To find x put y = 6.5 in equation 1:
2(6.5) - x = -7
x = 13 + 7
x = 20.
Therefore the ordered pair (20, 6.5) satisfies the equation.
Also, 4y = 4(6.5) = 26
New Frontier policies focused on domestic programs to expand education, widen the social safety net, and encourage Americans to serve those in need. The Peace Corps, a program which sent young volunteers overseas to help those in need, was probably one of the best-known New Frontier programs
