Answer:
Step-by-step explanation:
will form a sequence as,
499, 498, 497.......7 terms
Since there is a common difference between successive and previous term,
d = 498 - 499 = -1
This sequence is an arithmetic sequence.
Sum of n terms of an arithmetic sequence is,
where a = first term of the sequence
n = number of term
d = common difference
For the given given sequence,
=
=
= 3472
Therefore, sum of seven terms of the given sequence will be 3472.
Answer:
y = 25 + 3.5x, where x is a half hour
y = 25 + 3.5 (4 * 2) = $53
Step-by-step explanation:
Answer:
Let the total numbers of cars be ten then the total cars produced in one week would be 50
Probability of deficient cars on Monday = 4/10
Probability of deficient cars on Tuesday =1/10
Probability of deficient cars on Wednesday = 1/10
Probability of deficient cars on Thursday = 1/10
Probability of deficient cars on Friday = 3/10
Probability ( deficient car)= 10/50 or 1/5
Probability that it produced on Monday 4/10*1/5= 4/50= 2/25= 8/100= 0.08 or 8%
Probability of deficient cars on Monday = 4/10* 12/100= 48/1000= 0.048or 4.8%
Probability of deficient cars on Tuesday =1/10 *22/100= 22/1000= 0.022 or 2.2%
Probability of deficient cars on Wednesday = 1/10*22/100=22/1000= 0.022 or 2.2%
Probability of deficient cars on Thursday = 1/10*22/100=22/1000= 0.022 or 2.2%
Probability of deficient cars on Friday = 3/10*22/100= 66/1000= 0.066 or 6.6%
