50=16t^2
Divide both sides by 16
3.125=t^2
Find the square root of both sides (approximated)
1.77= t
Final answer: F
Answer:
And using the probability mass function we got:
And replacing we got:
Step-by-step explanation:
Let X the random variable of interest "number of students graduated", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We want to find the following probability:
And using the probability mass function we got:
And replacing we got:
We know from table that x intercept (when y or t(x) is 0) is -3
next we can move over the -y from the given equation
y = 4+ 4x
solving for when y is 0
0 = 4 + 4x
-4 = 4x
x=-1
Thus the first equation has larger intercept of -1
Answer:
combined velocity of the system = 0.033 m/s.
Step-by-step explanation:
taking the bullet and block as single system since there is no external force involved momentum is conserved .
initial momentum of the bullet = mv
where m is the mass of bullet and v is velocity of bullet.
and initial momentum of block = 0 since its velocity is 0.
therefore initial momentum of the system = mv
= 0.005×40
= 0.2
when the bullet stick of together with the block let the combined velocity of the system be V
therefore applying conservation of momentum
mv = (M+m)V
0.2=(6+0.005)V
therefore V = 0.033 m/s
Answer:
375/x = 125
1. 375/x = 125 -- given. You are given this information.
2. 375 = 125x -- multiplication property. You are multiplying each side by x to cancel it out as a denominator.
3. 375/125 = 125x/125 -- division property. You are dividing each side by 125 to isolate x.
x = 3
