Answer:
22 millilitres of 13% solution
23 millilitres of 19% solution
Step-by-step explanation:
A + B = 45
13A + 19B = 45 x 17 = 765
-13A - 13B + 13A + 19B = -650 + 765 = 115
5B = 115
B = 23
22 + 23 = 45
A = 22
Answer:
A. 0.625
B. 0
C. No
D. No
E. No
Step-by-step explanation:
We have these locations with the total of 56 as given in the question
A. Probability of landing anywhere but plain:
= 1 - probability of plain
= 1- 21/56
= 1 - 0.375
= 0.625
B. Probability of landing in a location which both a desert and a plain is the probability of a hit temperature and plain terrain. These two are independent of each other = 0
C. He cannot calculate probability of landing here because this information is not available
D. He cannot also, no information
E. Same thing here. No information
3 3/4 is the correct answer
