First for 7 we need to find out how many ninths are in a third and there are 3/9 in a third so now we multiply 3/9 by 2 which is 6/9 now we subtract 7/9-6/9 which is 1/9 so 1/9 is left. (Iff I'm wrong sorry I did this is like a minute.)

The straight line 2x + 3y = 7 meets the curve
NISA [10]

Step-by-step explanation:

xy + 10 = 0. => y = -10/x.

2x + 3y = 7. => 3y = -2x + 7, y = -2/3 x + 7/3.

When -10/x = -2/3 x + 7/3,

-10 = -2/3 x² + 7/3 x, 2/3 x² - 7/3 x - 10 = 0.

=> 2x² - 7x - 30 = 0

=> (2x + 5)(x - 6) = 0

=> x = -2.5 or x = 6.

dy/dx = d/dx [-10/x] = 10/x².

When x = -2.5, dy/dx = 10 / (-2.5)² = 1.6.

When x = 6, dy/dx = 10 / (6)² = 5/18.

Hence the gradients at the points are 1.6 and 5/18.

4.4.3 Quiz: Independence
lbvjy [14]

Answer:

\frac{2}{15}

Step-by-step explanation:

<h2><u>Lesson : Probability</u></h2><h2><u></u></h2>
  • We have a bag with 4 white chips and 6 black chips
  • Question : What is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?

4 white and 6 black

4 + 6 = 10

Choosing the first white chip : \frac{2}{5}

Since we took one out , now

3 white chips , 6 black chips

3 + 6 = 9

Choosing another white chip : \frac{1}{3}

\frac{2}{5} * \frac{1}{3}

\frac{2}{15}
