Answer:
(-∞ 2] ∪ [-4/3 ∞ )
Step-by-step explanation:
Given compound inequality,

( Subtraction property of inequality )
( Division property of inequality )

( a < b ⇒ - a > - b )
Hence, the solution of the given inequality is,
(-∞ -2] ∪ [-4/3 ∞ )
The equation is 7=1x and answer x=7
Answer:
Answer is <em>900</em>.
Step-by-step explanation:
To find:
Increase #500 in the ratio 16:10
Solution:
<em>New Number: Old Number = 16:10</em>
We are given the old number as 500.
Let the new number after increase = 
Now, using the above ratio:
<em />
<em>: </em>500<em> = </em>16:10

Therefore, the increased value of 500 in the ration 16:10 is <em>900</em>.
Answer:
sample variances
Step-by-step explanation:
The pooled variance method is used to estimate the variance of several different population with different means, but are assume to have the same variance.
The weights represent the sample variances.
So the correct answer is
sample variances
