Answer:
That number is 0.45
Step-by-step explanation:
3/5x = 2x - 63/100
0.63 = 2x - 3/5x
0.63 = 10/5x - 3/5x
0.63 = 7/5x
7x = 0.63*5 = 3.15
x = 3.15/7
Shapes with 9 points are considered a nonagon or a enneagon.
Answer:
0.333
Step-by-step explanation:
The first sequence starts at 1 and has a common difference of 2. It will include every odd number in the range.
__
The second sequence starts at 1 and has a common difference of 3. It will include odd numbers and the even numbers 4, 10, 16, .... That is, all even numbers of the form 6n -2 will be included. The last one corresponds to the largest value of n such that ...
6n -2 ≤ 1000
6n ≤ 1002
n ≤ 167
That is, 167 even numbers will also be excluded.
__
The third sequence starts at 1 and has a common difference of 4. Every number in this sequence is also a number in the first sequence.
__
So the numbers in these sequences include all 500 odd numbers and 167 even numbers, for a total of 667 numbers. The probability that a randomly chosen number is not in one of these sequences is ...
(1000 -667)/(1000) = 333/1000 = 0.333 . . . . p(not a sequence term)
Answer:
x = 6
Step-by-step explanation:
14 = 4x - 10
24 = 4x
x = 6
