is the size in wheels on the scale model .
<u>Step-by-step explanation:</u>
Correct Question : Tom has a scale model of his car. The scale factor is 1 : 12. If the actual car has 16-inch wheels, what size are the wheels on the scale model?
We have , The scale factor is 1 : 12. We need to find If the actual car has 16-inch wheels, what size are the wheels on the scale model .Let's find out:
Ratio of size of wheels to actual size of wheels is 1:12 , but actual car has 16-inch wheels So ,
⇒
{ x is size of wheel in scale model }
⇒ 
⇒ 
⇒ 
Therefore ,
is the size in wheels on the scale model .

Step-by-step explanation:
a. H0: μ = 26.6
b. Ha: μ > 26.6
c. Let x = the mean age for online students at De Anza College.
d. Student’s t-distribution
e. 9.98
f. p-value = 0.0000
g. Check student’s solution.
h. i. Alpha: 0.01
ii. Decision: Reject the null hypothesis.
iii. Reason for decision: The p-value is less than 0.01.
iv. There is sufficient evidence to conclude that the mean age of online students at De Anza College is greater than 26.6 years.i. (28.8, 30.0)
We're given a set of exterior angles for a polygon, here a quadrilateral. Exterior angles of any polygon add to 360 degrees.
46 + (12x + 37) + (12x - 2) + (20x - 29) = 360
44 x + 52 = 360
44 x = 308
x = 308/44 = 7
Check: The supplementary angles should add to 360 as well, they're the interior angles of a quadrilateral
(180-46) + (180 - (12(7) + 37)) + (180 - (12(7) - 2)) + (180 - (20(7) - 29)) = 360, good
