17<= e +14

17-14 <= e

3<= e

you just work it out as a normal equation, only when you ÷ or × with a negative number < changes into > and vice-versa.

Answer:

17<= e +14

17-14 <= e

3<= e

how to know if it true or false:

If you add the same number to both sides of an inequality, the inequality remains true. If you subtract the same number from both sides of the inequality, the inequality remains true. If you multiply or divide both sides of an inequality by the same positive number, the inequality remains true.

) furnace repair bills are normally distributed with a mean of 272 dollars and a standard deviation of 15 dollars. if 36 of thes
nexus9112 [7]
To evaluate the given probability we proceed as follows:
The z-score is given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
from the question:
mean=272, sig=15
but the sample is n=36, thus we shall have:
√σ/n
=15/√36
=2.5
thus the z-score will be as follows:
x=272
z=(272-272)/2.5=0
x=274
z=(274-272)/2.5==0.8
thus
P(272<x<274)
=P(z<0.8)-P(z<0)
=0.7881-0.5
=0.2881
Hence the answer is 0.2881

A fireman's water hose shoots 320 kg of water each second against the door of a building. The velocity of the water is 20 m/s an
NeX [460]

Answer:

6400\ \text{N}

Step-by-step explanation:

\dfrac{m}{t} = Mass flow rate of water = 320 kg/s

m = Mass of water on the door

t = Time

v = Velocity of water on the door = 20 m/s

Force is given by

F=\dfrac{m}{t}v\\\Rightarrow F=320\times 20\\\Rightarrow F=6400\ \text{N}

The average force is exerted by the stream of water is 6400\ \text{N}.
