The <u>correct answer</u> is:
The scale drawing is larger.
Explanation:
A scale for a scale drawing is written as a ratio in the form
(scale size):(actual size).
For example, on a map you may have a scale that says 1 in: 2 mi. This means that 1 inch on the scale is equal to 2 miles on the map.
The scale for this problem is 10 cm: 1 mm. This means that 10 cm on the scale drawing represents 1 mm on the actual object.
10 cm is larger than 1 mm, so the scale drawing is larger.
A reduction of 15% per year means 100-15=85% reducing factor.
1st year: 0.85×18000=$15300.
2nd year: 0.85×15300=$13005.
3rd year: 0.85×13005=$11054.25.
So after 3 years the value of the car is $11054.25 or $11054 to the nearest dollar.
Answer:
nonproportional
Step-by-step explanation:
x + 3
------- is definitely nonproportional. The reason for this is that the graph (a
8 straight line) does not pass through the
origin; it's offset by 3/8 unit up from the
origin.
Answer:
And we can find the probability with the complement rule and the normal standard distirbution and we got:
Step-by-step explanation:
Let X the random variable that represent the time spent reading of a population, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
And we can use the z score formula given by:
Using this formula we got:
And we can find the probability with the complement rule and the normal standard distirbution and we got:
