For samples of the specified size from the population described, find the mean and standard deviation of the sampling distribution of the sample mean, x with bar on top. The mean and the standard deviation of the sampled population are, respectively, 77.4 and 4.0. n=225.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
