You can always match 4 points using a cubic polynomial. A graphing calculator can find a cubic regression equation for you. This set of points is matched by
.. y = x^3 +3x^2 +5x +3

two urns contain white balls and yellow balls the first urn contains 7 white balls and 7 yellow balls and the second urn contain

faltersainse [42]

<u>Answer:</u>

The correct answer option is b) $\frac{1}{6}$ .

<u>Step-by-step explanation:</u>

We are given that the first urn contains 7 white balls and 7 yellow balls and the second urn contains 3 white balls and 6 yellow balls. We are to find the probability that both balls drawn are white.

This means that the first must be white and the second ball must also be white.

P (w, w) = $\frac{7}{14}$ × $\frac{3}{9}$ = $\frac{1}{6}$

Therefore, the probability that both the balls drawn are white is 1/6.

Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 problems. Each problem is

Sedaia [141]

Answer:

x + y = 29, 5x + 2y = 100

Step-by-step explanation:

First, create an equation based on how there are 29 problems on the test.

x + y represents all of the questions on the test, so it should be set equal to 29.

The first equation is x + y = 29.

Now, create an equation based on how the test is worth 100 points.

5x will represent the points from the questions worth 5 points, and 2y will represent the points from the questions worth 2 points.

These terms will be added together, and set equal to 100.

The second equation is 5x + 2y = 100.

So, the system of equations is x + y = 29, 5x + 2y = 100
