30 would be the upper q, and the whisker would go through 35 of the upper quartile.
hope i helped :)
I'm using <= as "less than or equal to", and >= as "greater than or equal to".
Let x = speed
For a car, it has to be at least 45: x >= 45 and it has to be at most 65: x <= 65
When you put these two together you have
Answer:
x < 15
Step-by-step explanation:
Let's first expand the parentheses on both sides. Remember that when expanding parentheses, the result will be the sum of the products of the "outside number" with each of the "inside number".
On the left, the parenthetical expression is: -6(x + 4). Here, the outside term is -6 and the inside terms are x and 4. So:
-6(x + 4) = -6 * x + (-6) * 4 = -6x - 24
On the right, the parenthetical expression is: -5(x + 6). Here, the outside term is -5 and the inside terms are x and 6. So:
-5(x + 6) = -5 * x + (-5) * 6 = -5x - 30
Now put these back in:
-6(x + 4) + 9 > -5(x + 6)
-6x - 24 + 9 > -5x - 30
-6x - 15 > -5x - 30
x < 15
Thus the answer is x < 15.
Hope this helps!
Answer:
116 = 116.
Step-by-step explanation:
Because the equations are the same, x + 4, they will always be equal to each other. 4 + 112 = 116.
If this helped I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
