Answer:
The large number is 17
Step-by-step explanation:
x+y=31⟹x=31−y
2x=y+11⟹x=y+11/2
2(y+11/2)=2(31−y)
y+11=62−2y
3y=51
y=17 x=14
Hope this helps, have a nice day! :)
Just find the surface area. 5*7=35, but 35*2=7<span>0</span>, because the top and bottom. Then do 7*3*2=42, for 2 parallel sides, and then 3*5*2=30. Now add 70+30+42=142 square inches. There's your answer.
Answer:
So after the second tablet there is 360-mg of drug in the body.
So after the third tablet there is 372-mg of drug in the body.
Step-by-step explanation:
We know that a doctor prescribes a 300-mg antibiotic tablet to be taken every eight hours. Just before each tablet is taken, 20% of the drug remains in the body.
We know that 20%=0.2.
We conclude that after the first pill, 300mg of the drug is in the body.
We have the following formula, to calculate how much mg of the drug is in the body after the second tablet:
So after the second tablet there is 360-mg of drug in the body.
We have the following formula, to calculate how much mg of the drug is in the body after the third tablet:
So after the third tablet there is 372-mg of drug in the body.
(8 + 16)
8 and 16 have three common factors . . . 2, 4, and 8 .
We can factor any of them out of the problem.
The greatest common factor is 8 . Let's factor that one out.
(8 + 16) = 8 (1 + 2)
Answer:
1. A) the data is more spread out
2. C) the data is less spread out
Step-by-step explanation:
1) Standard Deviation is a measure of dispersion, denotes the spread of data around measure of central tendency (usually arithematic mean).
A data set with higher standard deviation implies A) Data is more spread out or scattered, & vice versa less spread for less standard deviation.
2) Interquartile range is also a measure of dispersion, denoting difference between Q1 (25th percentile) & Q3 (75th percentile).
A data set with smaller interquartile range implies C) Data is less spread out, & vice versa more spread for higher interquartile range.
