The regression equation y = 3.648 • 1.182x approximates the cost to go on a safari, y, given the number of years since it opened in 2005, x. which is the best estimate for the cost of a vehicle to drive through the safari in 2013? a. $7.46 b. $12.44 c. $13.90 d. $34.50

Option C. $13.90

Solution:

Approximate cost to go on a safari ($): y

Number of years since it opened in 2005: x

y=3.648*1.182^x

Cost in year 2013: y=?

Year 2013→x=2013-2005→x=8

y=3.648*1.182^8

y=3.648*3.810130162

y=13.89935483

y=13.90

The best estimate for the cost of a vehicle to drive through the safari in 2013 is $13.90

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
