Students took two parts of a test, each worth 50 points. Part A has a variance of 25, and Part B has a variance of 36. The corre
Leona [35]

Answer:

Following are the solution to the given choices:

Step-by-step explanation:

In point a:

Calculating the variance of the test grade:

\to var(A+B)=var A + var B + 2 cov(A,B)

                       =25+36+2(0.8)\\\\=25+36+1.6\\\\=62.6

In point b:

\to var(A-B)=varA + var B - 2 cov(A,B)

                       =25+36-2(0.8)\\\\=25+36-1.6\\\\=59.4

The relationship between the top 20 students is also slight, so the top 20 students are more university-like than all secondary students.

Simplify 7(x + 3). 7x + 3 7x + 10 7x + 21 x + 21
Evgesh-ka [11]
The answer is 7x+21
Explanation: you have to distribute 7into c and three. So you would multiply 7 by x (or 1x) and 7 times 1 is 7 so it would be 7x and then you would multiply 7 times 3 which is 21 and there are no like terms with 7x and 21 so it’s just 7x+21
