You fitted a regression model on the height of a particular pine tree, after 20 years of growth, as a function of the elevation

the tree is growing in a coastal mountain. You found that linear regression was appropriate to study this question i.e., the relationship was linear. The regression model showed that tree height decreased 0.2 meters per meter gained in elevation and that tree height at sea level height (Om elevation) was predicted to be 110 m. The slope of this model was:______ (use the correct sign) while the intercept was:________ . The model predicts that a tree growing at an elevation of 25 m should be________ m tall. While the predicted elevation in the mountain that a 108 m tall tree will be found is________m.

Find the distance between (3,4) and (4,-6) if necessary, round to the nearest tenth.
Ratling [72]

Answer:

The distance is:

d = 10.0 units (Rounded to the nearest the Tenths Place)

Step-by-step explanation:

Given the points

  • (3,4)
  • (4,-6)

The distance 'd' between (3,4) and (4,-6)

\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):

d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

substituting the points values

   =\sqrt{\left(4-3\right)^2+\left(-6-4\right)^2}

   =\sqrt{1+10^2}

   =\sqrt{1+100}

   =\sqrt{101}

   =10.0  units (Rounded to the nearest the Tenths Place)

Thus, the distance is:

d = 10.0 units (Rounded to the nearest the Tenths Place)

You are studying for your final exam on the semester. Up to this point, you received 3 exam scores of 99%, 80%, And 70%. To rece
Alchen [17]
80*4=320
89*4=356
This is the range of the addition of all 4 scores.

99+80+70=249

320-249= 71
356-249= 107

[71, 100] would be the answer, unless you can get extra credit on the final.
