Answer:
1.8m^2 approx
Step-by-step explanation:
Given data
P1= 1400N
A1=0.5m^2
P2=5000 N
A2=??
Let us apply the formula to calculate the Area A2
P1/A1= P2/A2
substitute
1400/0.5= 5000/A2
cross multiply
1400*A2= 5000*0.5
1400*A2= 2500
A2= 2500/1400
A2= 1.78
Hence the Area is 1.8m^2 approx
Answer:
t=1
Step-by-step explanation:
Answer:
D.) If the mean typing speed of workers from the agency is 60 wpm, the probability of selecting a sample of 50 workers with mean 58.8 wpm or less is 0.267.
Step-by-step explanation:
In this case, the p value is what let's us determine the probability of getting the desired outcome. This would be 60 wpm.
If it is lower than the desired outcome, we know that this inference is not the <em>actual mean </em>of the data.
