[7, 2] + ([-3, 6] - [2, -4]) = [2, 12]

Answer: B) 6</h3>
===============================================
Explanation:
Add the equations by adding the terms straight down.
The x terms add to x+x = 2x.
The y terms add to y+(-y) = y-y = 0y = 0, so the y terms go away
The constants add to 5+7 = 12
The z terms add to -z+z = 0z = 0 and those go away as well
After all that adding, we have 2x = 12 which solves to x = 6 after dividing both sides by 2.
While writing inequalities we should know about symbols
a>b means a is greater than b
a<b means a is less than b
so here we have to write
difference between t and 7= t-7
given t-7 is greater than 10 so t-7>10
and t-7 is less than 20 so t-7<20
combining above two we get
10<t-7<20, <span>17 < t < 27</span>
Answer:
0.0625 = 6.25% probability that the first card drawn is a diamond and the second card is a club
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Probability of independent events:
The probability of independent events happening at the same time is the multiplication of the probabilities of each events.
First card:
A standard deck has 52 cards, of which 13 are diamonds. So
Second card:
The first card is replaced, so still 52 cards, of which 13 are clubs. So
What is the probability that the first card drawn is a diamond and the second card is a club?
Each drawing is independent, so
0.0625 = 6.25% probability that the first card drawn is a diamond and the second card is a club
