Answer:

<h2>a. No, the points are in a curved pattern.</h2>

Step-by-step explanation:

The residual values are basically the difference between Given values and Predicted values.

So, the complete table would be

x Given Predicted Residual

1 -2.7 -2.84 0.14

2 -0.9 -0.81 -0.09

3 1.1 1.22 -0.12

4 3.2 3.25 -0.05

5 5.4 5.28 0.12

Now, to make a residual plot, we just need to graph all points formed by x-colum and residual column.

The image attached shows the residual plot.

Therefore, the right answer is a., because in the residual plot you can notice that the points are in a curved pattern, like in a parabola-like pattern.

The altitude (i.e., height) of a triangle is increasing at a rate of 2 cm/minute while the area of the triangle is increasing at

Answer:

A = 1/2 B H area = 1/2 base X height

B = 2 A / H = 2 * 99 / 12 = 16.5 cm

dA / d t = 1/2 * (B dH / dt + H dB / dt)

dB / dt = (2 dA / dt - B dH / dt) / H

dB / dt = (2 * 1.5 cm^2 / min - 16.5 cm * 2 cm / min) / 12 cm

dB / dt = (3 - 33) / 12 cm/min = -2.5 cm/min

How do you solve this?

masha68 [24]

Here's what i found online:

a/3+4=6

We simplify the equation to the form, which is simple to understand
a/3+4=6

Simplifying:
 + 0.333333333333a+4=6

We move all terms containing a to the left and all other terms to the right.
 + 0.333333333333a=+6-4

We simplify left and right side of the equation.
 + 0.333333333333a=+2

We divide both sides of the equation by 0.333333333333 to get a.
a=6

Hope this helped :-)
