Answer:
Q1 or the 25th percentile is 204.5
Step-by-step explanation:
Combine all data values in TI-84, excel, or other software and make a box and whisker plot. The Q1 is the first vertical line on the plot
Answer:
f(x) = (x - 3)(x + 1) → Corresponds with the first (raised higher ) ∪ shaped graph
f(x) = -2(x - 1)((x + 3) → Corresponds with the ∩ shaped graph
f(x) = 0.5(x - 6)((x + 2) → Corresponds with the second (lower) ∪ shaped graph
Step-by-step explanation:
For the function f(x) = (x - 3)(x + 1)
We have;
When x = 0, y = -3
When y = 0 x = 3 or -1
Comparing with the graphs, it best suits the first ∪ shaped graph that rises here than the other ∪ shaped graph
For the function;
f(x) = -2(x - 1)((x + 3)
When x = 0, y = 6
When y = 0, x = 1 or -3
Which corresponds with the ∩ shaped graph
For the function;
f(x) = 2(x + 6)((x - 2)
When x = 0, y = -24
When y = 0, x = -6 or 2
Graph not included
For the function;
f(x) = 0.5(x - 6)((x + 2)
When x = 0, y = -6
When y = 0, x = 6 or -2
Which best suits the second ∪ shaped graph that is lower than the other (first) ∪ shaped graph
For the function;
f(x) = 0.5(x + 6)((x - 2)
When x = 0, y = -6
When y = 0, x = -6 or 2
Graph not included
For the function;
f(x) = (x + 3)((x - 1)
When x = 0, y = -3
When y = 0, x = -3 or 1

The other two expressions that have value of 256 is 4⁴ and 16².
Given the exponent expression 2⁸ has a value of 256.
We want to write two other exponential expressions that have value 256.
The given expression is 2⁸=256
The above expression can be written as
2×2×2×2×2×2×2×2=256
By using the Associative property of multiplication, we can write them as
(2×2)×(2×2)×(2×2)×(2×2)=256
4×4×4×4=256
4⁴=256
and it can also be written as by using the associative property of multiplication again and get
(2×2×2×2)×(2×2×2×2)=256
16×16=256
16²=256
Hence, the two other exponential expression of 256 other than 2⁸ is 4⁴ and 16².

Take a piece of paper and write a line with dashes having a number below it until 50. Then Go to 34 on your number line and then go backwards by 28. (34 - 28) the answer should be 6. The number line helps you count steps forward/backwards. :)

Answer:
2%
Step-by-step explanation:
20% takes 10 years to decay
To find per year decay, we divide the percentage by the number of years, so we get unit rate of years {per year]. Thus we have:
20%/10 = 2% per year
It's that simple.
Hence, the percentage by which the substance decays each year is 2%
