Find the indicated values, where

Rom4ik [11]

Answer:

option (b) is correct.

The value of $g(f(3)-2f(1))$ is 0.

Step-by-step explanation:

Given: $g(t)=t^2-t$ and $f(x)=1+x$

We have to find the value of $g(f(3)-2f(1))$

Consider the given function $f(x)=1+x$

First evaluate value of function f(x) at x = 3 and 1 then substitute it in $g(f(3)-2f(1))$ .

f(3) = 1 + 3 = 4

f(1) = 1 + 1 = 2

Substitute, we get

$g(f(3)-2f(1))=g(4-2(2))$

Solving further , we get,

$g(f(3)-2f(1))=g(4-4)=g(0)$

Now evaluate $g(t)=t^2-t$ at t = 0 , we get,

$g(0)=0^2-0=0-0=0$

Thus, value of $g(f(3)-2f(1))$ is 0.

Thus, option (b) is correct.

Some player heights are normally distributed with a mean 5.0 feet and a standard deviation of 0.3 feet. Let X. equals the height

Mrrafil [7]

Answer:

P(4.7≤x≤5.3)≈0.6827≈68.27%

Step-by-step explanation:

Notice that 4.7 is 1 standard deviation below the mean (μ) and 5.3 is 1 standard deviation above the mean. Thus, by the Empirical Rule, ±1σ represents about 68.27% of the data in a normal distribution, meaning that P(4.7≤x≤5.3)≈0.6827
