Answer: 2 dollars per mask
Step-by-step explanation:
100 000/50 000 = 2
2 dollars per mask
Congruent sides pair with each other. AB is congruent to FG, so put FG (x) under or below 16 (it doesn't matter as long as FH is next to it). Cross multiply, then continue as if it's an equation. With that, you get the answer that x, or FG, equals 9 m.
Answer: I believe the answer is D(the last Choice)

It is true because they both equal 42 =True
Answer:
See explanation below
Step-by-step explanation:
Here, a director of manufacturing must convince management that a proposed manufacturing method reduces costs before the new method can be implemented. The current production method operates with a mean cost of $220 per hour.
a) The alternative and null hypotheses would be:
H0: μ ≥ 220
Ha: μ < 220
b) Comment on the conclusion when H0 cannot be rejected:
When we fail to reject the null hypothesis H0, there is not enough evidence to conclude that the mean cost can be reduced from $220. Therefore the manager's proposed method cannot be implemented.
c) Comment on the conclusion when H0 can be rejected:
When the null hypothesis, H0 is rejected, there is enough evidence to conclude that the mean cost can be reduced from from $220. Therefore the manager's proposed method can be implemented.
