Answer:

<em>See the Venn diagram attached</em>

<u>Numbers given:</u>

  • <em>Total</em>: 100
  • Either a cat of a fish: 70
  • Cat: 46
  • Cat and fish: 16

<u>Neither a cat or a fish:</u> 100 - 70 = 30

<u>Fish:</u> 70 - (46 + 16) = 70 - 62 = 8

<u>Required probabilities are:</u>

  • a) P(neither) = 30/100 = 0.3
  • b) P(f) = (16 + 8)/100 = 0.24
  • c) P(f not c) = 8/100 = 0.08

Please answer this question...
irina1246 [14]

Answer:  I believe the standard deviation will remain the same, 6, choice A.

Step-by-step explanation:  Standard deviation is calkculated based on the difference of each point from the mean.  If 10 were added to each score, the mean would also increase by 10.  That would mean that the difference between the mean and each score would be exactly the same, leading to an identical standard deviation.  Sounds crazy, but that's what numbers do for a living.

5x^{4}-7x^{3}-5x^{2}+5x+1-0
den301095 [7]

Answer:

5x^4 -7x^3-5x^2+5x+1

Step-by-step explanation:

Hey!

You would just add all the numbers up, and by making sure that you combine all like terms. In this case it is just 1-0 = 1 and so the solution would be the same as your question but with a 1 and you would get rid of the -0.

Hope this helps!

5+2(3x-4)=12x-11 is 5+6x -8 = 12x -11, 5-8+11= 12x-6x, “8= 6x” so option B is correct
