Answer:
See below.
Step-by-step explanation:
No. Triangles Perimeter
1 14
2 18
3 22
We see from the table, after the first perimeter (= 14), with each increase of 1 in the number of triangles, the perimeter increases by 4.
As an equation it is P = 14 + 4(n - 1) where P = perimeter and n = number of triangles.
Answer:
<u><em>Answer is below</em></u>
Step-by-step explanation:
<span>choose any two points on the line.
draw a right-angled triangle with the line as hypotenuse.
use the scale on each axis to find the triangle's: vertical length. horizontal length.
work out the vertical length ÷ horizontal length.
<span>
the result is the gradient of the line.</span></span>

I'm not sure if this are right
Answer:
Yes. Fertilization increases grape yields by more than 5 pounds.
Step-by-step explanation:
Let f-fertilized and o-old(unfertilized)
#First, we use our data to calculate the standard error:
#State both null and alternative hypothesis:
#We determine our degrees of freedom as 87.02(using R), we now compute the t-value as:
Since, the p-value is low, we Reject the null hypothesis. The is enough evidence suggesting that grape yields increase by more than 5 pounds than mean yields of unfertilized grapes.
