If s(f) = x-7 and t(x) = 4x^2-x+3, which expression is equivalent to (t•s)(x)

sertanlavr [38]

Answer:

$t(s(x)) = 4x^2 -15x +59$

Step-by-step explanation:

The expression (t•s)(x) means t(s(x)) or t of s of x. It means to substitute s(x) into the equation for t(x).

$t(s(x)) = 4(x-7)^2 -(x-7) + 3\\t(s(x)) = 4(x^2-14x+49) - x + 7 + 3\\t(s(x)) = 4x^2 - 14x + 49 - x + 10\\t(s(x)) = 4x^2 -15x +59$

Mashutka [201]

Answer: 2.71

Step-by-step explanation:

We know that the formula to calculate the standard error is given by :-

$S.E.=\dfrac{\sigma}{\sqrt{n}}$ , where $\sigma$ is the standard deviation and 'n' is the sample size.

Given : Standard deviation : $\sigma=\$9$

Sample size : $n=11$

Then , the standard error of the mean is given by :-

$S.E.=\dfrac{9}{\sqrt{11}}=2.7136021012\approx2.71$

Hence, the standard error of the mean = 2.71
