sample may not be valid. Firstly, she had a
relatively small sample size, meaning that
she had a potentially large margin of error.
Additionally, she was asking students from
her math class, which could also have
created a bias simply due to the fact that
they were currently doing math. In order to
survey a more valid sample, she should
consider student of other grade levels and
from other classes to ensure that she has
the most information possible and to create
variation in her sample.

a florist orders sunflowers every 6 days, starting from the sixth day of the year, and daisies every 4 days starting from the fourth day of the year. when is the first THREE TIMES she will order the flowers on the same day?
Answers
Answer: 12th day
Step-by-step explanation:
Given , A florist orders sunflowers every 6 days and daisies every 4 days.
When it started from same day, then the next day she orders both kinds of flowers on the same day will be LCM (6,4), where LCM = Least Common Multiple.
Prime factorization:
6 = 2 x 3
4 = 2 x 2
LCM(6,4) = 2 x 2 x 3 = 12
Hence, she will order both kinds of flowers every 12 days.

for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm

Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,

Here is a hanger that is in balance. We don’t know how much any of its shapes weigh. How could you change the number of shapes on it, but keep it in balance? Describe in words or draw a new diagram.
Answers
We can take away the two circles from both sides. We don't know the weight of each circle, but we know that the circles on each side balance each other out. Meaning that taking away those circles does not change the balance. Similarly, we can take away two squares from each side to keep things balanced as well.
After those subtractions, we're left with 2 squares on the left side and nothing else. On the right side, we have 4 triangles only.
2 squares balance with 4 triangles, which must mean 1 square balances with 2 triangles (divide both values by 2).
If you add a square to one side, you must add 2 triangles to the other side to keep things balanced.
-----------------------
Going back to the original diagram, we can have the following on the left side
2 circles4 squares2 triangles .... this is what we addAnd on the right side we would have
2 circles3 squares ... two squares initially but we added 1 extra square4 trianglesThis new configuration is balanced. I added the 2 triangles to the left side while the right side got the square.
There are other configurations possible because we can add as many squares to each side, as long as we add 2 triangles per extra square. Also, the order of the shapes on either side doesn't matter. All that matters is the total weight pulling down.
Also, we could easily add the same shape to both sides as possibly the easiest way to change the configuration. For instance, if you add a circle to both sides, then things stay balanced. So again, there are many ways to answer this.

The line plot shows the ages of participants in two group activities at a science center.
What conclusion can be drawn about the data sets?
More 14- and 15-year olds are in group 2 than in group 1.
Group 1 participants have a greater range in age than group 2 participants.
The median age of participants in group 2 is older than the median age of participants for group 1.
The mean age of participants in group 2 is younger than the mean age of participants in group 1.
Two line plots one above the other, both are labeled from ten to twenty five by ones. The top line plot is labeled Age of participants dash group one and it has five Xs above fifteen, four Xs above fourteen, two Xs above thirteen, sixteen, and nineteen and one X above ten, twelve, seventeen, eighteen, and twenty. The bottom line plot is labeled Age of participants dash group two and it has four Xs above seventeen, three Xs above eighteen, two Xs above eleven, fifteen and sixteen and one X above twelve, thirteen, fourteen, ninteen, twenty, twenty three, and twenty five.
