Answer:
The florist delivered more than 4000 roses
Step-by-step explanation:
One dozen is 12 roses, so the fast florist delivered a total of 368 x 12 = 4416 roses. That is more than 4000 roses, so the answer is More than 4000 roses
The answer is (4,3). In order to get to point "s" from the midpoint you have to add 2 to the "x" value and 3 to the "y" value. Thus, to find point "r" you simply have to do the opposite by subtracting 2 from the "x" value and 2 from the "y". So, 6-2 and 6-3. This will get you an answer of (4,3). Hope this helped :))
A coin has one of two outcomes: heads or tails.
Each has an equal probability of occurring, meaning that they each have a 50% chance to occur. (They need to add up to 100% because they include all the outcomes, divide that into two equal parts and...)
This is what we call theoretical probability. It's a guess as to how probability <em>should</em> work. Like in the experiment, it's not always going to be 50-50.
What <em>actually happens</em> is called experimental probability. This may vary slightly from theoretical probability because you can't predict probability with complete certainty, you can only say what is <em>most likely to happen</em>.
We want to find the probability of getting heads in our experiment so we can compare it to the theoretical outcome. To do this, we need to compare the number of heads to the total number of outcomes.
We have 63 heads, and a total of 150 coin flips.
That makes the probability of getting a heads 63/150.
The hard part is getting this ratio into a percent.
You can try simply dividing, but you should be able to notice something here.
SInce the top and the bottom of our fraction are both divisible by 3, we can <em>simiplify</em>.
63 ÷ 3 = 21
150 ÷ 3 = 50
So we could say that 63/150 = 21/50.
A percent is basically a fraction out of 100.
Just like you can divide the parts of a ratio by the same number and it will stay the same, you can also multiply. To get the fraction out of 100, let's multiply by 2.
(since 50 × 2 = 100)
21 × 2 = 42
50 × 2 = 100
21/50 = 42/100 = 42%
Comparing our experimental probability to the theoretical one...it is 8% lower.

Answer: 1046</h3>
=====================================================
Explanation:
The fancy or strange looking E symbol is the greek uppercase letter sigma, to mean sum. So they want you to add the terms in the form x^2. The x values are from the list given to us.
x = 16 leads to x^2 = 256
x = 13 leads to x^2 = 169
etc etc
After squaring all the x values, we have this new list {256, 169, 25, 400, 196}
Lastly, you add up all the squared values to get the final answer of 256+169+25+400+196 = 1046
2x² (6x³+3x+4) is your answer
hope this helps
