Answer:
not sure about second, but one is the 30, 60, 90 angle triangle. That one i'm 100 percent sure of (30, 60, 90).
Step-by-step explanation:
Answer:
{x | x∈ R, x < -2}
Step-by-step explanation:
Given
See attachment for graph
Required
Determine the inequality
From the attachment, we can see that there is an open circle or -2.
This represents either < or >
<u>Solving further:</u>
The arrow points to the left of -2.
This means that the number line represents numbers less than -2. i.e. < -2
If the numbers are represented with x.
The inequality is: x < -2
So, we have: {x | x∈ R, x < -2}
Answer:
Mean = 75
Median = 73.5
Mode = 95
Range = 36
Step-by-step explanation:
Given:
Sort:
To find:
Mean:

Sum of all data divides by amount.

Therefore, mean = 75
Median:
If it’s exact middle then that’s the median. However, if two data or values happen to be in <em>middle</em>:

From 59,60,70,77,89,95, since 70 and 77 are in middle:

Therefore, median = 73.5
Mode:
The highest value or/and the highest amount of data. Mode can have more than one.
From sorted data, there are no repetitive data nor same data. Consider the highest value:
Therefore, mode = 95
Range:
or highest value - lowest value
Thus:

Therefore, range = 36
4^2+3(4)=28 hope this helps
STEP ONE:
Set up the equation
45.25 + 7.25x = 25.25 + 9.75x
STEP TWO:
Subtract 7.25x from both sides
45.25 = 25.25 + 2.5x
STEP THREE:
Subtract 25.25 from both sides
20 = 2.5x
(Flip equation)
2.5x = 20
STEP FOUR:
Divide 2.5 from both sides
x = 8
Since x represents weeks, it will take 8 weeks for Brian and Dakota to have the same amount of money.
Hope this helped!
