we are given
The pump can generate a pressure of 2.3x107 pa
so,
a radius of 0.041 m
so,
a stroke lasting 29 s, the piston moves 0.57 m
so,
Firstly, we will find area
now, we can use power formula
F=pA
W=Fh
so, W=pAh
we can plug it
now, we can plug values
now, we can simplify it
Power=2386.92414 watt.........Answer
Answer:
P=2.326
Step-by-step explanation:
Raw Score (X):=1000
Population Mean (μ):=460
Standard Deviation (σ): =Sqrt(npq)
Where n=1000, p=460/1000=0.46 and q=1-0.46=0.54
Sqrt(npq)=sqrt(460X0.54)=15.7607
Z = (X - μ) / σ
Z = (1000 - 460) / 15.7607
Z = 34.26244
For p-value 0.01
P(x=0.01) = 2.32635
Hence, P=2.326 t 3 decimal places.
Answer:
He must get 33 hits in his next 46 times at bat to finish the year with a .400 batting average
Step-by-step explanation:
The player has already batted 134 times and will still bat 46 times. So in the end of the year, he is going to have 134 + 46 = 180 at bats.
How many hits does he need to have to hit .400?
This is 40% of 180, which is 0.4*180 = 72.
He has already 39 hits, so in his next 46 at bats, he will need 72 - 39 = 33 hits.
.67,2/3,5/9,7/12,.58
Hope this helps :D
