Answer:
BD = 28
Step-by-step explanation:
BC and CD are within line BD, so add those to make up for the length of BD
21 + 7 = 28
Answer:
1.) scatter plot is attached below.
There is no sufficient evidence to support the claim that there is a linear correlation between overhead widths of seals from photographs and the weights of the seals.
Step-by-step explanation:
Given the data :
Overhead width : 7.2 7.5 9.7 9.3 8.7 8.2
Weight : 119 156 243 200 199 188
The linear correlation Coefficient, R = 0.946
Using the Pvalue calculator for R score ;
Pvalue = 0.0149
Since, Pvalue > Α ; WE fail to reject the Null and conclude that there is no sufficient evidence to support the claim that there is a linear correlation between overhead widths of seals from photographs and the weights of the seals.

Standard form of an equation can be represented by ax^2 + bx + c = y. where a b are coeficients and c is a constant value. for your equation to work we have to say:
a = -1
b = 4
c = -7
you have to be sure to put the negative value. if i said
a = 1
b = 4
c = 7
and i plugged these in i would get:
(1)x^2 + (4)x + (7)
which becomes
x^2 + 4x + 7
this is not right. if i used the first values i stated then:
(-1)x^2 + (4)x + (-7)
-x^2 + 4x - 7
this is correct
