I NEED HELP UNDERSTANDING BOTH OF THESE QUESTIONS

Answer:

For the first image: -0.4/9

Second Image = 1.53/0.45

Step-by-step explanation:

a + b = 1.6 - 2 = -0.4 (The symbols just make it stay negative)

2 - c = 2 - (-7) = 2 + 7 = 9

--------

2a - 1/3  =  2(-3/5) - 1/3  =  -1.2 -1/3  =  -1.5333

b/15  =  -6.75/15  =  -0.45

(The two negatives make it positive)

Hope this helps

One Endpoint is 9,18 and the midpoint is 14,16 what the other end point
Valentin [98]
\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
&({{ 9}}\quad ,&{{ 18}})\quad 
%  (c,d)
&({{ x}}\quad ,&{{ y}})
\end{array}\qquad
%   coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)

\bf \left( \cfrac{x+9}{2}~,~\cfrac{y+18}{2} \right)=\stackrel{\textit{midpoint}}{(14,16)}\implies 
\begin{cases}
\cfrac{x+9}{2}=14\\\\
x+9=28\\
\boxed{x=19}\\
-------\\
\cfrac{y+18}{2}=16\\\\
y+18=32\\
\boxed{y=14}
\end{cases}

Brainlist answer!!Can I get some help with this, please!!
Gemiola [76]
A) The question would be "Does cell phone use time correlate to brain cancer?". The population is all cell phone users. The sample is the 469 people with brain cancer, and the 422 healthy people. 

B) This sample size may not portray the entire population of users because the positive results may have been fabricated by factors other than cell phone use. You would have to figure out the population size and determine the correct sample size. 

C) This study may not portray cell phone use correlation over a large population efficiently because of the sample size and the predetermined conclusion that cell phone use causes cancer.
