Answer:
Step-by-step explanation:
This is an arithmetic sequence. Each term is 9 more than the preceding term.
The 25th term is 5+24*9 = 1085.
Sum of first 25 terms is 25(5+1085)/2 = 13625
Answer:
Ratio is 1:5; there are 5 times more blue marbles so there should be 10 blue marbles
Step-by-step explanation:
7:35 creates a 1 green marble to every 5 blue marbles ratio. So for every green marble there are 5 blue marbles. If you have 2 green marbles then you have 5+5 blue marbles
Answer:
The experimental probability that a light build chosen at random has no defects is 99.5 % or P(A)=0.995.
Step-by-step explanation:
let S be the sample space for the inspection of the light bulbs.
Therefore, n(s) = 800
let ' A ' be the event of no defects bulbs.
Therefore, n(A) = 796
Now the Experiment probability for a light bulb chosen has no defects will be given by,

Substituting the values we get

The experimental probability that a light build chosen at random has no defects is 99.5 % or P(A)=0.995.
The square root of 26 is 5.099020.
