Explanation:
To round a number to the nearest tenth , look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.
Answer:a. This study involved comparison of two populations. What were the populations?
1) Pregnant women who took the drug.
2)Pregnant women who didn't take the drug.
b. Do you suppose the data were obtained in a survey or experiment?
- Survey
C.Provide a descriptive statistic that could be used to estimate the number of women out of 1000 in this population who have tissue abnormalities.
-out of 1,000 women developed tissue abnormalities
63/3980=.0158
15.8%
D. remember that women whose mothers took the drug were twice as likely to develop tissue abnormalities.)
___ out of 1,000 women developed tissue abnormalities
15.8/2
7.9
e. Medical sudies often use a relatively large sample (in this case 3980). Why?
medical studies often use a relatively large sample (in this case, 3980) because disease occurrences can be rare and difficult to observe when only isolated populations are considered.
Answer:There are Multiple different types of energy transfer, including gravitational potential energy, elastic energy, and kinetic energy.
Explanation:When you use your potential energy to jump, the trampoline uses its potential energy in its springs to push back against you.
Answer: The required [a] for slotion will be -62.7
Explanation:
The specific rotation of pure quinine= -165
% of pure quinine= 69%
% of its enantiomer=ee=31%
Enantiomer excess =(ee)=excess of a single enantiomer/entire mixture×100
Now,
Excess of a single enantiomer=69% - 31%=38%
Entire mixture=69% + 31%= 100%
(ee)=38/100 × 100
=38%
Net rotation= 0.69-0.31=0.38
Hence, [a] for solution will be = -0.38×165= -62.7
Answer:
.25 (1/4) x 42 (kg)= 10.5ML
Explanation:
Convert kg to lbs by diving the lbs by 2.205.
Then multiply your kg by .25 and there's your answer.
