Answer:
Option B
Step-by-step explanation:
Given equation gives the information about the temperature in Vancouver over a period of 4 hours.
y = -2x + 43
Here 43 represents the initial temperature and (-2) represents the temperature fall in every one hour.
x = duration or time
Therefore, equation states that initial temperature when measured was 43 °F and it is dropping by 2 degrees per hour.
Option B is the answer.
The slope intercept form of that equation its 0.10y=0.25x+5
Total number of cards = 52
Total number of spades = 13
Total number of face cards that are not spades = 3 x 3 = 9
Total number of spades or face cards = 13 + 9 = 22
P(a or b) = 22/52 = 11/26
Answer: 11/26
Work inside the brackets first, and then you can multiply the two equations if they are able to be mutiplied...
