Answer:
Step-by-step explanation:
Ok so the negatives go first, so heads up for help. The 0 isn’t first. It’s in the middle of posting and negative I would make a time line on a piece of paper put the 0 in the center and work from there
It’s quite simple. All you have to do is take your men and women which is 2 and multiply that by 10. 2*10=20! So, 20 will be your answer
<h2>Answer :</h2>
Katherine's marks = 84,92,84,75,70
Total marks = 84+92+84+75+70 = 405
No. of observations = 5
Mean = Total sum of observations/No. of observations
Mean = 405/5=81
Expected mean = 84
Let expected total marks be = n
84=n/5
84×5=n
<h3>n=420</h3>
Answer:
x-3
Step-by-step explanation:
(x+5)(x-1)(height)=x3+x2-17x+15
x2+5x-1x-5(h)=x2+4x-5
so what times x2+4x-5 will equal the volume
look at the constant -5 and think what will multiply with that to get 15 so -3 right so then check the rest of it by doing (x2+4x-5)(x-3) =x3−3x2+4x2−12x−5x+15
=x3+x2−17x+15 so the answer is x-3
Hope this helps! :)
