The racial achievement gap in the United States refers to disparities in educational achievement between differing ethnic/racial groups. [1] It manifests itself in a variety of ways: African-American and Hispanic students are more likely to earn lower grades, score lower on standardized tests, drop out of high school, and they are less likely to enter and complete college than whites, while ...
Jensen's inequality generalizes the statement that a secant line of a convex function lies above its graph. Visualizing convexity and Jensen's inequality In mathematics , Jensen's inequality , named after the Danish mathematician Johan Jensen , relates the value of a convex function of an integral to the integral of the convex function.
Jensen's argument consisted of a series of related claims. [10] IQ tests are valid measurements of a real human ability—what people generally describe as "intelligence"—that is important to many parts of contemporary life. Intelligence, as measured by IQ tests, is about 80 percent heritable. Intelligent parents are much more likely to have ...

Jensen's formula can be used to estimate the number of zeros of an analytic function in a circle. Namely, if is a function analytic in a disk of radius centered at and if | | is bounded by on the boundary of that disk, then the number of zeros of in a circle of radius < centered at the same point does not exceed
