Hello!

You plug the values in for x and y

x = 4
y = 5

\frac{ 4^{2}+ 5^{3}  }{2 + 4}

Combine like terms

\frac{16 + 125}{6}

Add

\frac{141}{6}

Divide

The answer is 23.5

Hope this helps!

scoundrel [369]

Answer:

The formula to calculate standard deviation from probability is \sqrt(n*p*(1-p)). n is the sample size, and 200 in this case (number of putts for practice). p is 80% or 0.8, the probability that he can make it. So the standard deviation is \sqrt(200*0.8*(1-0.8)=\sqrt(200*0.8*0.2)=\sqrt(16)=4.

Lerok [7]

Answer:

  g(t) = 2t+3

Step-by-step explanation:

You want a definition of g(t) so you can write the equation ...

  r = g(t) . . . . . . radius is a function of time

We are told the radius at t=0 is 3, so the third choice is the obvious one:

  g(t) = 2t +3 . . . . . radius t seconds after the radius began increasing
