Linear line is a straight line. In this equation which is in slope intercept form (y=Mx+b) M the number in front of the x is the slope (also known as common different) -3 is the slope, you do rise rise over run -3(down 3 to the right 1) or (up 3 to the left 1) and 3 is the y intercept. Y intercept is when x=0 (3,0). If you graph the point (3,0) you go down 3 to the right 1.
You can approximate the square root of 30 by taking the square root of a number close to it. This is called local linearization. You can take the square root of 36, which is 6, and the square root of 25, which is 5, and state that the square root of 30 is approximately somewhere between 5 and 6
A...the proportion of heads your friend observes is closer to 0.5
Your answer would be 4/9 or 44%
Answer:
Step-by-step explanation: we will have to set up some parameters that will help us as we go.
1kg= 2.205 pounds
1 euro= $1.35
From the question, we can see that 1kilo of apples costs 2.50 euros.
So to convert our euros to dollars, we multiply 2.50 by the exchange rate, viz;
2.50 * 1.35= $3.375.
In essence, 1kg of apples costs $3.375.
Now to get how much each pound costs per dollar. We say,
If 2.205 pounds cost $3.375
Then we can get the price of 1 pound by dividing the price by the weight. So;
3.375/2.205= $1.53
