Answer:
y = 44
Step-by-step explanation:
Well if y varies directly with x it means that when y increases x increase and if y decrease x also decreases.
So let us put this in a equation,
<em>y = kx
</em>
where 'k' is constant
so <em>k = y/x</em>
let us put the figures of x and y from given first statement;
x = 7 and y = 18
so, k = 18 / 7
which means, k = 2.57
lets put this value of k in the equation above,
we know from statement that, x = 17 and k = 2.57
so, y = 2.57 (17)
which means, y = 43.71
or we can round it off to, y = 44
Keep adding 10 starting from 0 until u get to 100:

That's right! 3/4 of 3/4 means multiplying 3/4 by 3/4.
The GCF is 3
so factored would be: 3(x+5)
Answer: Explanatory variable = " number of times the owner has an advertisement played on the radio"
Response variable = "number of new customers who will visit a shop"
Step-by-step explanation:
- An explanatory variable is a kind of independent variable that can be manipulated by researcher in a study to check the response of the response variable.
In the given situation , the business owner is predicting the number of new customers who will visit a shop based on the number of times the owner has an advertisement played on the radio.
Here , He is controlling the advertisement played on the radio to see the response of customers.
Therefore ,
Explanatory variable = " number of times the owner has an advertisement played on the radio"
Response variable = "number of new customers who will visit a shop"
