Which point should be removed for the graph to represent a table of equivalent ratios?
vodomira [7]
<h3>Answer:  D.   (5,15)</h3>

===========================================================

Explanation:

As the graph shows, three of the four points are on the same line. That line being y = 5x. This line has slope 5 and y intercept 0.

The point not fitting this pattern is the point (5,15), so that is the final answer.

For the other three points, note that the jump from x to y coordinate is "times 5". For example, y = 5x = 5*2 = 10 for point A. In contrast, point D has a jump of "times 3" when going from x to y.

--------------

Alternatively, you can divide each y coordinate by its corresponding x coordinate.

  • For choice A, we have y/x = 10/2 = 5
  • Choice B has y/x = 15/3 = 5
  • Choice C has y/x = 20/4 = 5

All results are 5 so far. Choice D doesn't follow the trend and instead has y/x = 15/5 = 3. This is another way to show that choice D is the answer.

Marissa rode her bike to the park and back home. She lives 2 3/10 miles from the park. How many miles did Marissa ride her bike
Dovator [93]
2\frac{3}{10} +2\frac{3}{10} =\frac{(2\times10)+3}{10}+\frac{(2\times10)+3}{10} =\frac{20+3}{10}+\frac{20+3}{10}\\\\=\frac{23}{10} +\frac{23}{10} =\frac{23+23}{10} =\frac{46}{10} =4\frac{6}{10} =\boxed{\bf{4\frac{3}{5}}}

Marissa rode 4 3/5 miles in all.

Y−21&lt;85. Graph the solution.
Tasya [4]

Answer:

y < 106

Step-by-step explanation:

Step 1: Add 21 to both sides.

  • y-21+21 < 85+21
  • y < 106

Therefore, the solution is y < 106.

To graph it on a graph:

  • circle 106 on the graph- DO NOT FILL IN THE CIRCLE
  • point the arrow to the left direction

A. Use the​ one-mean t-interval procedure with the sample​ mean, sample​ size, sample standard​ deviation, and confidence level
PtichkaEL [24]

Answer:

a) (17.227, 22.773)

b) 2.773

c) 2.773

Step-by-step explanation:

Given:

Sample size, n = 25

Standard deviation, s = 4

Sample mean, x' = 20

Level of significance, a = 0.98 = 1 - 0.98 = 0.02

The degrees of freedom, df, for a t-distribution = n - 1 = 25 - 1 = 24

Using the t table, the Critical value = t_\alpha _/_2, _d_f = t_0_._0_2_/_2, _2_4 = t_0_._0_1_, _2_4 = 3.4668

Margin of error, E = t_\alpha _/_2, _d_f * \frac{\sigma}{\sqrt{n}} = 3.4668 * \frac{4}{\sqrt{25}} = 2.773

Limits of 98% confidence interval, we have:

Lower limit : x' - M.E = 20 - 2.773 = 17.227

Upper limit: x' + M.E = 20 + 2.773 = 22.773

Therefore, (17.227, 22.773) is 98% confidence interval.

b) Let's the margin of error by taking half the length of the confidence interval.

Since we are to use half the length of CI, we have:

M.E = \frac{22.773 - 17.227}{2} = 2.773

c)M.E = t_\alpha _/_2, _d_f *s/\sqrt{n}

= t * \frac{s}{\sqrt{n}} = 3.4668 * \frac{4}{\sqrt{25}} = 2.773
