Answer:
The probability is 1/20 or 5 %
Step-by-step explanation:
1). First, how many shirts there are in the drawer?
9 + 6 + 5 = 20 shirts
2). Since we are choosing 1 shirt out of 20, then the probability will be 1/20 or 5%.
Hope this helpsss))
About miles.
Subtract the flat rate of 1.75 from the spending limit of 10$ which leaves you with 8.25 then divide the rest of your spending money (8.25$) into your rate per mile (0.65) , so essentially , 8.25 / 0.65 which leaves you with the answer of ;
12 miles.
Answer: The equation is y= -2x -4
Step-by-step explanation:
The slope intercept form is like y=mx+b so we know the slope which is m but we just need to find the y intercept.
and we will use the given coordinates to find the y intercept by putting in the x and y coordinates into the formula y=mx + b
-6= -2(1) + b
-6= -2 + b
+2 +2
b= -4
