Central angle = 360 / 24 = 15 degrees

ARc length = r * theta, where theta is the angle in radians and r = radius
= 15 * 15 * pi/180
= 3.93 feet to nearest hundredth.

Area of sector = area of circle / 24 = pi*15^2 / 24 = 29.45 ft^2

In a regression equation predicting income (measured in $1000s) with education (measured in years), the intercept (a) equals 1.5

Sindrei [870]

Answer:

a. at zero years of education, income equals $1500

Step-by-step explanation:

The equation for income 'I', as a function of years of education 't' is given by:

$i(t) = bt+a$

Where b is the regression coefficient and a is the intercept.

The intercept is the value assumed by the function for t = 0 years of education:

$i(0) = 0*4 +1.5\\i(0) = 1.5$

Since the income function measures income in $1,000s, at zero years of education, income equals $1500
