F(x) = 4x + 7, g(x) = 3x2

Luda [366]

Answer:

(1)

$(f+g)(x)=3x^2+4x+7$

(2)

Step-by-step explanation:

we are given

$f(x)=4x+7$

$g(x)=3x^2$

we have to find (f+g)(x)

we can write

$(f+g)(x)=f(x)+g(x)$

now, we can plug values

and we get

$(f+g)(x)=4x+7+3x^2$

we can also write as

$(f+g)(x)=3x^2+4x+7$

so, answer is

$(f+g)(x)=3x^2+4x+7$

All the possible samples of n = 3 scores are selected from a population with m = 30 and s = 5 and the mean is computed for each

const2013 [10]

Answer:

Step-by-step explanation:

We know that population mean μ is 30 and population standard deviation σ is 5.

Further average or mean is computed for all sample means. So, the mean of sampling distribution of mean μxbar is calculated.

The property of sampling distribution is that mean of all possible sample means or mean of of sampling distribution of mean μxbar is equal to the population mean μ.

μxbar=μ=30

μxbar=30.

Thus, the obtained value will be 30.
