Answer:
25% of the people either buys a digital camera or a home theater receiver buth not both.
Step-by-step explanation:
The percentage of the customers that buy both a digital camera (D) and a home theather receiver (H) are included in the respective percentages (28% and 5%), so to calculate the percentage that buy only one of the items, we have to substract the percentage that buy both items from each of the percentages:
- If 28% of the people purchase a digital camera, and 4% buy both items, then 28-4=24% of the people buy only a digital camera.
- If 5% of the people purchase a home theater receiver, and 4% buy both items, then 5-4=1% of the people buy only a home theater receiver.
Then, we can add 24% and 1% and have that 25% of the people either buys a digital camera or a home theater receiver buth not both.
Answer:
To find a
sin 30=a/6in
1/2=a/6in
2a=6in
a=6in/2
a=3in
To find b
cos 30=b/6in
/3/2=b/6in
2b=/3*6in
b=2/3(two radical three)
I don't get the radical sign so I use / sign on the last 3 steps on the second
