Asample with a mean of m = 40 and a variance of s2 = 20 has an estimated standard error of 1 point. how many scores are in the sample?

4 + 5 7/9= 9 7/9

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

other answer is correct. i had used the radius of the radius somehow. a website:

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
