- a) HR = 24
- b) AT = 32
- c) MR = 29
- d) R is the midpoint of <u> MH </u> and <u> AT </u>
==========================================================
Explanation:
a)
MR = 24 is given. Note the single tickmark on this segment. The other segment HR has the same tickmark, so it is the same length as MR.
HR = MR = 24
-----------------
b)
The double tickmarks tell us TR and RA are the same length. They combine to form segment AT. So this means segment AT is cut in half to get TR and RA.
TR = (1/2)*(AT)
2*TR = AT.... multiply both sides by 2
AT = 2*TR
AT = 2*16
AT = 32
-----------------
c)
MH is cut in half at point R for similar reasoning as part b)
Put another way, MH is twice as long as MR.
MH = 2*MR
58 = 2*MR
2*MR = 58
MR = 58/2
MR = 29
-------------------
d)
R is the midpoint of segment MH because R cuts MH in half. Point R bisects MH.
R is also the midpoint of AT for similar reasoning. It's all based on the tickmarks telling us which segments are congruent to one another.
Answer:
0.16
Step-by-step explanation:
For a normal distribution, the 68-95-99.7 rule says that 68% of the distribution lies within 1 standard deviation from the mean, 95% within two standard deviations and 99.7% within three standard deviations.
From the question,
Mean μ = 298 ml
Standard deviation σ = 3 ml
A value of 295 ml is within one standard deviation = 68%.
Since it's on the lower side, it's within 68% ÷ 2 = 34%.
The lower half below the mean is 50% of the distribution. Hence, for a selection less than 1 standard deviation, the probability is
50% - 34% = 16% = 0.16
Answer: x/y^3
Step-by-step explanation:
So you divide 27/9 which is 3. Then it ix x^7-x^6=x. And then it is y^2-y^5=y3
27*x*x*x*x*x*x*x*y*y/9*x*x*x*x*x*x*y*y*y*y*y
Doing this makes it easier so you cross each variable out for each one in both sides. 3x/y^3 would be your answer.
Based on the time it took the patient to recover and the mean and standard deviation, the z-score is 1.5.
<h3>What is the z-score?</h3>
The z-score for this patient who takes 7 days to recover can be found as:
= (Time taken to recover - Mean) / Standard deviation
Solving for the z-score gives:
= (7 - 5.2) / 1.2
= 1.8 / 1.2
= 1.5
The first part of the question is:
The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.2 days and a standard deviation of 1.2 days.
