Of 10<br> Find the gradient of the line segment between the points (2,-2) and (0,-6).

Veseljchak [2.6K]

Answer:

<h3>The answer is 2</h3>

Step-by-step explanation:

The gradient of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

From the question we have

$m = \frac{ - 6 - - 2}{0 - 2} = \frac{ - 6 + 2}{ - 2} = \frac{ - 4}{ - 2} = 2 \\$

We have the final answer as

The function f(x) = -6x. The graph of g(x) is f(x)vertically stretched by a factor of 7 and reflected in the x-axis. What is the

Vera_Pavlovna [14]

we are given a function

$f(x)=-6x$

First translation:

The graph of function is vertically stretched by a factor of 7

Whenever we vertically stretch any function by 'a' units

so, we can write it as

$g(x)=a\times f(x)$

Here, it is vertically stretch by 7

so, we get

$g(x)=7\times -6x$

$g(x)=-42x$

Second translation:

Whenever we reflect any function about x-axis

we multiply y-value by -1

so, we can write it as

$g(x)=-f(x)$

Here , it is reflected in the x-axis

so, we can multiply by -1 to y-value

we get

$g(x)=-1\times -42x$

$g(x)=42x$ .............Answer

Consider an urn containing 8 white balls, 7 red balls and 5 black balls.

weqwewe [10]

Answer + Step-by-step explanation:

1) The probability of getting 2 white balls is equal to:

$=\frac{8}{20} \times \frac{7}{19}\\\\= 0.147368421053$

2) the probability of getting 2 white balls is equal to:

$=C^{2}_{5}\times (\frac{8}{20} \times \frac{7}{19}) \times (\frac{12}{18} \times \frac{11}{17} \times \frac{10}{16})\\=0.397316821465$

3) The probability of getting at least 72 white balls is:

$=C^{72}_{150}\times \left( \frac{8}{20} \right)^{72} \times \left( \frac{7}{20} \right)^{78} +C^{73}_{150}\times \left( \frac{8}{20} \right)^{73} \times \left( \frac{7}{20} \right)^{77} + \cdots +C^{149}_{150}\times \left( \frac{8}{20} \right)^{149} \times \left( \frac{7}{20} \right)^{1} +\left( \frac{8}{20} \right)^{150}$

$=\sum^{150}_{k=72} [C^{k}_{150}\times \left( \frac{8}{15} \right)^{k} \times \left( \frac{7}{15} \right)^{150-k}]$
