<em>The question is attached</em>
=======================
<u>Answer options:</u>
A. Players at school 1 typically spent more time in the weight room than players at school 2
- False, as per plot boxes up to 75% of players from school 1 spend up to 10 hours but up to 75% of players from school 2 spend up to 12 hours in the weight room
B. The middle half of the data for school 1 has more variability than the middle half of the data for school 2
- True. 4 hours variation for school 1 vs 3 hours variation for school 2
C. The median hours spent in the weight room for school 1 is less than the median for school 2 and the interquartile ranges for both schools are equal
- True as it is 8 hours for school 1 and 9 hours for school 2
D. The total number of hours spent in the weight room for players at school 2 is greater than the total number of hours for players at school 1
- True. Taking into account a sum of 5 numbers of the plot box. For School 1 it is: (3+4+8+10+16)= 41 and for school 2 it is: (3+6+9+12+14) = 44. Totals will have similar ratio.
Answer:
b. because rise over run 1 is positive 3 is negitive
Answer:
10
Step-by-step explanation
i took the test so i know this is right and i dont know if you still need the answer but here you go evidence shown in photo
Answering part A:
5x + -3x 7y + 3y + 2y 4xy doesn't have a like term
Step-by-step explanation:
like terms are when in an equation they might have variables that match like 4y + 7y they have the same variable which is y or 6 + 7 they don't have a variable at all but they are similar in that way. Btw why it says -3x is because I changed the equation to be all addition so I did kcc you don't have to do that if you find a different solution :) anyway lets move on to part b
Answering part B:
4xy + 2x −2y
Answer:
Step-by-step explanation:
We want to find the minimum-degree polynomial with real coefficients and zeros at:
As well as a <em>y-</em>intercept of 64.
By the Complex Root Theorem, if <em>a</em> + <em>b</em>i is a root, then <em>a</em> - <em>b</em>i is also a root.
So, a third root will be 4 - 4i.
The factored form of a polynomial is given by:
Where <em>a</em> is the leading coefficient and <em>p</em> and <em>q</em> are the zeros. More factors can be added if necessary.
Substitute:
Since we want the minimum degree, we won't need to add any exponents.
Expand the second and third factors:
Hence:
Lastly, we need to determine <em>a</em>. Since the <em>y-</em>intercept is <em>y</em> = 64, this means that when <em>x</em> = 0, <em>y</em> = 64. Thus:
Solve for <em>a: </em>
Our factored polynomial is:
Finally, expand:
