57/100 is the answer for your problem
Answer:
3/2 or 1.5
Step-by-step explanation:
Had trouble reading your post. It's important that you separate each equation with plenty of spaces, or, b etter yet, type only one equation per line:
<span>x-y=19 -2x+y/6=28 should be:
</span><span> x-y=19
-2x+y/6=28
Does (-31,-56) satisfy this system? Is (-31) - (-52) = 19? No. Move on to the next system and check again whether or not (-31, -56) is a solution.</span>
The answer to this is -11/12
Answer:
The survey is meaningless because of nonresponse bias.
Step-by-step explanation:
The sample who responded (567) is less than half of Hayden's blog readers (1200). So, in this case, the results were really invalidated, because of the great absence of response, and the survey cannot be taken seriously at least statistically speaking.
567---100
x------35
x≈199 people said No
y= 368 said yes
