Answer:
I am pretty sure the answer would be $107.31. Sorry if I'm wrong.
Step-by-step explanation:
First you take the total of the 3 DVD's (45.99) and you divide that by 3 (number of DVD's) to get 15.33 which is called the unit price. Then, you take your unit price and multiply that by how many items you are going to buy.
45.99 / 3 = 15.33
15.33 x 7 = 107.31
Since Matrix A is added with Matrix B
then each component must be added to its corresponding component
a11+b11=0
a11=-b11
if
a11*b11=-16
then a11=+4 and b11=-4 or a11=-4 and b11=4
a11 is postive so our answer should be
a11=4 and b11=-4
Answer:
1.273584906 yds / second
Step-by-step explanation:
Take the number of yards and divide by the number of seconds
6.75 yds / 5.3 seconds

Answer:
- P(Yellow)=0.25
- P(Not Red)=0.65
Step-by-step explanation:
P(Red)=0.35
P(Green)=0.4
(a)Since there are three colours inside the bag
P(Red)+P(Green)+P(Yellow)=1
0.35+0.4+P(Yellow)=1
P(Yellow)=1-(0.35+0.4)
P(Yellow)=0.25
(b) In probability, the sum of an event and its complement is 1.
Therefore:
P(Red)+P(Not Red)=1
0.35+P(Not Red)=1
P(Not Red)=1-0.35
P(Not Red)=0.65
