For the equation r/3+t=w express r in terms of t and w

KengaRu [80]

r/3 + t = w to get r by itself (Which I think is your question)

r/3 + t = w subtract t from both sides

r/3 = w - t and times by 3 on both sides

r = 3(w-t)

The graph of a linear equation passes through three of these points: (0,5), (2, 2), (3, 1), and (4.-1).

sdas [7]

Answer:

Answer:

80% Confidence interval: (0.4603,0.7397)

Step-by-step explanation:

We are given the following in the question:

Sample mean, $\bar{x}$ = MD = 0.60 points

Sample size, n = 9

Sample variance = 0.09

Sample standard Deviation =

$=\sqrt{\text{Sample Variance}} = \sqrt{0.09} = 0.3$

80% Confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 8 and}~\alpha_{0.20} = \pm 1.397$

$0.60 \pm 1.397(\frac{0.3}{\sqrt{9}} ) = 0.60 \pm 0.1397 = (0.4603,0.7397)$
