Suppose Wesley is a marine biologist who is interested in the relationship between the age and the size of male Dungeness crabs.
Eva8 [605]

Answer:

20.24 cm

Step-by-step explanation:

Here, since the age of the crab is given in months and the regression line was computed using the age in months, we just have to replace the value of the age in the formula to estimate the size.

The formula obtained for the estimated size Y was

Y = 9.1411 + 0.4775X  

where X is the age in months

Replacing X with 23.2417, we get

Y = 9.1411 + 0.4775*23.2417 = 20.24 cm

Komok [63]
I just kind of sat here playing with numbers i dont really know a shortcut but the answer is 10 chickens and 15 rabbits 
10*2= 20 each chicken has two legs so thats 10 heads 20 legs
15*4=60 each rabbit has four legs so thats 15 heads 60 legs
15+10=25 heads
20+60=60 legs

Mrs. Chip bought 2 sheets and a blanket and paid $41. Mrs. Dale bought a sheet and 4 blankets and paid $80.
Katyanochek1 [597]

Answer:

  • Sheet = $12
  • Blanket = $17

Step-by-step explanation:

<u>Let the cost of a sheet be s and cost of a blanket be b</u>

  • 2s + b = 41
  • s + 4b = 80

<u>From the first equation we get:</u>

  • b = 41 - 2s

<u>Substitute in the second equation</u>

  • s + 4*(41 - 2s) = 80
  • s + 164 - 8s =  80
  • 7s = 84
  • s = 12

<u>Then</u>

  • b = 41- 2*12 = 17
