question 1 :- sum of all angles of a triangle is 180°

so, x + 39° + 25° + 15° = 180°

⇒x + 79° = 180°

⇒x = 101°

question 2 : draw the along with AD and make and triangle as shown in figure.

as ABCD is a parallelogram. so, angle FDE = 180° - x

and angle FED = 180° - x [ as FEA + FED = 180° ]

now from ∆DEF,

50° + 180° - x + 180° - x = 180°

⇒230° - 2x = 0

⇒x = 105°

also read : If (A + B) =(A-B) then the angle between the Ả and B.

Makers of generic drugs must show that they do not differ significantly from the "reference" drugs that they imitate. one aspect

Answer:

Step-by-step explanation:

subj ref drub gen drug

1 1738 3340

2 2594 2613

3 2526 1138

4 2344 2738

5 938 1287

6 1022 1284

7 1338 1930

8 2463 2120

9 2779 1613

10 2256 3052

those are the 10 first ones, you want to calculate the mean of the absorption time for about drugs, you can do this by summing all the times and dividing it by the total of samples, in this case 10.

for the reference drug the mean is 1999.8

for the generic drug the mean is 2018.8

which says that the generic drug is absorbed a little bit slower in mean, but this may be because our samples took other one first, so now we see the other 10, i will only put the math here

for the sample drug 2097.4

for the generic drug 2240.66

where i discarded the sample number 11 because there may be a error there.

then in bout cases you can see that the generic drug is absorbed slowly.

Answer:

Step-by-step explanation:

we first subtract 5-4 =1 . 62-1+2(8-22)-8
then 8-22 =-14 ( negative 14).
 62-1+2-14-8
then 62-1=61. 61+2=63. 63-14=49. 49-8=41
41 is your final answer
