Eight times the reciprocal of a number equals 4 times the reciprocal of six. Find the number

GenaCL600 [577]

Let the # be n.

Then 8(1/n) = 4(1/6). Mult both sides by 6n to elim. the fractions:

6n(8) 6n(4)
------- = -------- => 48 = 4n, and so n = 12 (answer)
n 6

1) The table and graph shows the relationship between GPA, X, and SAT score, y.

Artist 52 [7]

The statement (A), statement (B), statement (D) are correct because the equation is y = 437.9x + 439.4

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

From the data given, we can calculate the correlation coefficient, slope of the line, and y-intercept.

r = 0.90

Since r is close to 1 shows a strong correlation.

Slope of the line of best fit = 437.9

Y-intercept of line of the best fit = 439.4(Refer to the attached picture)

The line will be:

y = 437.9x + 439.4

Thus, the statement (A), statement (B), statement (D) are correct because the equation is y = 437.9x + 439.4
