Answer:
N s or Kg m/s
Step-by-step explanation:
Impulse is the product of the force and time or mass and velocity.
Impulse = force x time
, or
Impulse = mass x velocity
Therefore; the SI units of impulse is newton-second (N · s). Reduced to base units in the International System of Units ( SI ), a newton-second is the equivalent of a kilogram-meter per second (kg · m/s).
The line y = - x is a lean line with an inclination of 45° measured clockwise from the negative x axis.
The reflection throunh this line would result in moving the x-coordinates to negative x and y-coordinates to negative y.
The rule is multiply each coordinate times negative 1.
Answer:
- a) about 3.0%
- b) about 7×10^-6
Step-by-step explanation:
These sorts of calculations are best done with a calculator that knows statistics.
a) The z-value of the limit ofv interest is (45,000 -35,551)/(5100) ≈ 1.8743. The empirical rule tells you between 16 and 2.5% of the distribution will lie above a limit that is between 1 and 2 standard deviations. So, our calculator value of 3% is approximately correct.
b) The standard deviation of the sample mean is reduced by a factor of √75 from that of the parent distribution for a sample size of 75. Then the z-value is ...
... (38,000 - 35,441)/(5100/√75) ≈ 2559/588.90 ≈ 4.345
The probability of exceeding this valus is pretty small, about 6.95×10^-6.
The area of triangle is 7 square units, which is mentioned in option B. It is obtained from the given diagram.
Step-by-step explanation:
The given is,
For above question diagram is missing, so i attach the diagram.
Step:1
Formula for area of triangle from the coordinates,
.............(1)
Where,
are coordinates
From the given,
A ( 1, 1 ) -
B ( 4, 0 ) -
C ( 3, 5 ) -
Equation (1) becomes,
Area,
= 7
Area of triangle, A = 7 square units
Result:
The area of triangle is 7 square units, which is mentioned in option B. It is obtained from the given diagram.
