Use the regression calculator to compare students’ SAT scores based on their IQ scores. A 2-column table with 8 rows. Column 1 is labeled I Q with entries 115, 84, 111, 120, 105, 98, 96, 88. Column 2 is labeled S A T with entries 1,440, 780, 1,20, 1,560, 1,240, 1,200, 1,000, 920. The trend line shows correlation. The equation of the trend line is

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
