Answer:
set is a collection of distinct elements. vector is an element of a vector space.
Step-by-step explanation:
We'll represent the distance as d and the time as t.
d= 3(t+7) because Gilda is 7 minutes late when travelling 3 mph
d= 4(t-5) because Gilda is 5 minutes early at 4 mph
d= 3t + 21
d= 4t -20
3t +21 =4t -20
41=t
d= 3(41) +21= 144
The distance is 144 miles.
Answer:
1. y=3/2x + 12 2. y= 1/4x + 8
Step-by-step explanation:
Use the slope formula to get the slope for each line. Then plug either of the x and y coordinates into the formula y= mx + b and also plug in the slope that you just found and solve for b.
Answer:
-$0.16
Step-by-step explanation:
The expected value is the sum of the outcomes multiplied by their probabilities.
E(X) = 1/38 (+68) + 37/38 (-2)
E(X) = -0.16
Answer:
0.2 = y
Step-by-step explanation: You have to isolate y
<u> 7 = 35y</u>
35 35
0.2 = y
RECHECK:
7 = 35y
7 = 35(0.2)
7 = 7
YES, this is a true statement.
Hope this helps you!!! :)
