Yo download photos math in take a pic of your problem in it would give you your answer
For the 2nd equation, you need solve for y to get it by itself so once thats done you get y=9x+27 but since the x values (also the slope) aren't equal, they can't be parallel
Answer: 32x-68
Step-by-step explanation:
(f•g) is equal to f(gx)
f(x)=4(2x-5)+3
Which is 8x-20+3=8x-17
Now multiply by 4.
4(8x-17)
= 32x-68
Answer:
0.6495
Step-by-step explanation:
This is question based on conditional probability
The probability that a customer plans to make a purchase = 0.32.
The probability that a customer plans not to make a purchase = 1 - 0.32
= 0.68
The probability of responding to an advertisement given that the customer plans to make a purchase = 0.63
The probability of responding to an advertisement given that a person does not plan to make a purchase = 0.16.
Given that a person responds to the advertisement, what is the probability that they plan to make a purchase is calculated as:
0.32 × 0.63/(0.32 × 0.63) + (0.16 × 0.68)
= 0.2016/ 0.2016 + 0.1088
= 0.2016/0.3104
= 0.6494845361
Approximately = 0.6495
