Probaility in general is defined as the ratio of positive outcomes over the total number of outcomes.
In the first example, the total outcomes are 16; let us count the positive ones. There are 8 even numbers from 1-16. The prime numbers are 2,3,5,7,11,13. Out of those, only 5 are odd. Hence, in total there are 13 positive outcomes. Thus, the probability is 13/16=81.25%
Let's restrict the problem to the students that studied for the exam; the proportion is 0.57 of the total students. 0.52 of the total students studied and saw an increase in their exam. Hence, the probability that a student who studied saw an increse is 0.52/0.57 (here a positive outcome is the proportion that saw an increase and the total outcomes are all the students that studied). 0.52/0.57=91.22%
C because 5 is order than 2 I hope this help
Answer:
You need to invest at a continuous compound interest rate of 6.701355026%
Step-by-step explanation:
The formula to use is the compound interest formula:A=P(1+r/100)^t
where A=Total amount at the end of the investment period
P=Principal amount
R=Rate of interest
T=Investment tenor/time
Now,
350,000=50000(1+r/100)^30 is what needs to be simplified to 6.701355026%
The 5 rounds to 3 so it is 4.3
Answer:
The short story have 26 pages
The novel's pages is 364
Step-by-step explanation:
Step one:
given data
let the short story have x pages
so that the novel's pages will be 14x
the combined pages for novel and short story is =390 pages
Required
the individual number of pages
14x+x=390
15x=390
divide both sides by 15
x=26
the short story have 26 pages
the novel's pages will be 14(26)= 364
