Answer:
<u>y = 10/11 x + 2.45</u>
Step-by-step explanation:
Equation of the line
First find the gradient
formula = 
= 
=
= 10/11
m is the gradient
equation of a line
y- y1 = m(x-x1)
y-7 = 10/11 (x-5)
y-7 = 
- 
<u>y = 10/11 x + 2.45</u>
<u />
<em>NB i rounded of -50/11 +7 = 2.4545..... to 2.45 </em>
Answer:
The scientist’s conclusion is not appropriate because it is based on a subjective appreciation (“significantly greater than”).
<em>How “greater” is “significantly greater”?
</em>
A more objective and technical approach would be fixing a level of significance, let's say 0.05 or 0.01 for example, measuring the samples means and standard deviations and then proceeding with an appropriate hypothesis testing in order to see if the differences in means are really significant.

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(-3/2) = -1......(
perpendicular to a line with a slope of -3/2)
a = 2/3 y=(2/3)x+b
the line that passes through (-2, -2) :- 2 =
(2/3)(-2)+b
b = -2/3
<span> the equation is : y = (2/3)x-2/3</span></span>
<span><span>y =(2/3)(x-1)</span></span>
