need help to see if I did ok. Question: Consider points A(-2,0), B(2,3) and C(5, -1) forms a triangle. What is slope AB, AC and BC. I got AB=1/2, BC= -2, and AC = i1/2. Correct or did I goof?
Looks like 3 strikes, none are correct
slope AB = (3-0)/(2-(-2))
= 3/4
slope AC = (-1-0)/(5-(-2))
= -1/7
slope BC = (-1-3)/(5-2)
= -4/3
Researchers at Jackson Hospital asked 40 randomly selected patients about their sleep habits. Sixteen reported sleeping 8 hours or more each night. If there are 700 patients in the hospital, estimate the number of patients who sleep 8 hours or more each night.
We can use a proportion to estimate the number of patients who sleep 8 hours or more each night:
16/40 = x/700
Solving for x, we can cross-multiply:
40x = 16 * 700
x = (16 * 700)/40
x = 280
Therefore, we can estimate that 280 patients at the hospital sleep 8 hours or more each night.
Which survey question is biased?
"Are you in favor of the new policy, or do you think it's a terrible idea?"
This survey question is biased because it is asking respondents to either agree or disagree with the statement that the new policy is a terrible idea, which is a negative and loaded question. The question is designed to elicit a particular response rather than gather unbiased information about respondents' opinions of the new policy. A more neutral and unbiased question would be: "What is your opinion of the new policy?" and then provide response options such as "favorable", "neutral", or "unfavorable".
