Answer:
Usually it means to solve it. Sometimes they give you values to substitute in for variables (letters) in the math sentence/equation/expression.
Does that make sense?
Step-by-step explanation:
Answer:
The mean is 0.32 and the standard deviation is 0.0122.
Step-by-step explanation:
Given that the Tampa Times polled 1,457 adults in the city to determine whether they put on their shirt before they put on their pants.
Of the respondents, 48% said they put their shirt on first.
32% of all adults actually put their shirt on first
i.e. sample proportion is 48% while population proportion is 32%
Hence sampling distribution follows a distribution with mean = population proportion p
Hence here mean = 0.32
Std deviation of sampling distribution = 
Hence option 3) The mean is 0.32 and the standard deviation is 0.0122.
is right
Answer:
she should beat a speed of v₂ = 6.04 m/s in order to win the competition
Step-by-step explanation:
Since the momentum p is defined as
p = m*v
where
m= mass of the ball
v= velocity of the ball
denoting 1 and 2 as the first and second bowler , then to reach the momentum of the first bowler
p₂=p₁
therefore
m₁*v₁ = m₂*v₂
v₂ = v₁ * (m₁/m₂)
replacing values
v₂ = v₁ * (m₁/m₂) =8.6 m/s * (4.5 kg/6.4 kg ball) = 6.04 m/s
then since the momentum p = m*v increases with increasing v (at constant m) , she should beat a speed of v₂ = 6.04 m/s in order to win the competition
Answer:
0
Step-by-step explanation:
The smallest perfect cube would be 0 since it cannot be negative and zero raised to the third power would still be 0
Answer:
4x-4/x^2
Step-by-step explanation:
So we can first write out the equation.
It would be:
8/2x-4/x^2
First we can get a common denominator:
8/2x*x^2/x^2=8x^2/2x^3
and
4/x^2*2x/2x=8x/2x^3
Now we have
8x^2/2x^3-8x/2x^3
or
8x^2-8x/2x^3
We can divide everything by x
8x-8/2x^2
divide everything by 2
4x-4/x^2
