Answer:
84 couples
Step-by-step explanation:
First add the number of couples that have only one spouse that prefers dramas.
23+39+37+27=126
126 couples out of 250 prefer dramas.
126/250=.56 or 56 percent
To find the answer by making a prediction based on this data, you would find 56% of 150.
150x.56=84 out of the additional 150 surveyed couples will have one spouse that prefers a drama.
So, bike=b and accessories=a.
b+a=320
Since the bike is worth 7 times more than the accessories, the b would turn into 7a (because 7 times the cost of accessories is the cost of the bike).
The equation would now turn into 7a+a=320.
Solve for a.
7a+a=320
8a=320
a=40
Now that you know the cost of the accessories, you multiply that 40
by 7 to get the cost of the bike.
40(7)
280
The cost of the bike is $280.
The cost of the accessories are/is $40.
These are the steps for transforming y=1/x to y=1/4x -12:
Step 1: Compress the original function by 4 in x direction. This will yield,
y= 1/4x
Step 2: The resulting function in step 1 is moved down by 12 spaces. The resulting function will be;
y= 1/4x -12
6x+33-2(3x+1)
17+14
30+1
60-29
18+13
