A group of 30 randomly selected students have a mean score of 24.6 with a standard deviation of 3.3 on a placement test. What is the 95% confidence interval for the mean score, μ, of all students taking the test?

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
