Answer:
x ≤ 435
Step-by-step explanation:
Given is the following condition.
The sum of a number and 15 is less than and equal to 450.
So, if the number is x, then we have
x + 15 ≤ 450
⇒ x + 15 - 15 ≤ 450 - 15
⇒ x ≤ 435
Therefore, the solutions of the number are either 435 or less than 435 up to negative infinity. ( Answer )
Answer:
the value of k is 23-9(8x - 7)8 * 3(2 + 1)
Step-by-step explanation:
The variation in any sample group is simply the square of
the correlation coefficient, that is:
variation = r^2
Therefore given an r value, we can simply directly
calculate for variation percentage.
variation = (0.743)^2
variation = 0.552 or 55.2%
