This answer would be -375
This is what I get. Total will be 4187.56 with Interest 2187.56.
By using the formula:
To find amount :
A=p (1+r/n)^n×t
Where
P=2000,r=3%,n=1,t=25
So plug in and solve A=2000(1+0.03/1)^1×25
To find interest you use formula A=p+I
A=4187.56, p=2000,i= we need to find.
4187.56=2000+I
4187.56-2000=I
2187.56=i
Answer:
its 21 obviously
Step-by-step explanation:
this is because
<em>![8 {6 \times 58964 \sqrt[45 \sqrt{66x3 \times \frac{?}{?} } ]{?} \times \frac{?}{?} }^{2}](https://tex.z-dn.net/?f=8%20%7B6%20%5Ctimes%2058964%20%5Csqrt%5B45%20%5Csqrt%7B66x3%20%5Ctimes%20%5Cfrac%7B%3F%7D%7B%3F%7D%20%7D%20%5D%7B%3F%7D%20%20%5Ctimes%20%5Cfrac%7B%3F%7D%7B%3F%7D%20%7D%5E%7B2%7D%20)
</em>
Just comparing your (x, y) points to the values on the table, it looks like b) would be the quick answer. Since it states under the table to use average values within each range.
So for x=62 (the weight), we have y=122 (the iron count) which would be the average of the range between 115 and 129.
Similiarly, x=70 corresponds to y=146, which is the average of 139 and 153.
You could take the average values of your highest and lowest iron count ranges compare them to the max-min weight to get your slope. Looks like it would be (155-112)/(73-58)= 43/15= 2.8666 repeating. That would make sense with the slope in the equation listed in b) as well.
