The probability of choosing a purple marble from the given parameters is given as; 29%

<h3>How to find the Probability?</h3>

We are given;

Probability of drawing an orange marble = 23% = 0.23

Probability of of drawing a white marble = 48% = 0.48

Thus, probability of drawing a purple marble is;

P(purple marble) = 100% - (23% + 48%)

P(purple marble) = 29%

The histogram is in attached file.

Step-by-step explanation:

a)

The width of class interval=range/desired number of classes

The width of class interval=(maximum-minimum)/7

The width of class interval=(200-10)/7

The width of class interval=190/7

The width of class interval=27.14=28 (rounded to next whole number)

Rewrite this standard form quadratic equation into vertex form by completing the square. Upload your work here to show your thin
Alex787 [66]

Solution :

Given the equation :

$y = x^2 - 6x+3 $

$y=1(x^2 - 6x +n)+3$

$n = \left(\frac{b}{2}\right)^2$

$n = \left(\frac{6}{2}\right)^2$

n = 9

$y=1(x^2 - 6x +9-9)+3$

$y=1(x^2 - 6x +9)-9+3$

$y=1(x-3)^2- 6$

Therefore the vertex form of $y = x^2 - 6x+3 $  is  $y=1(x-3)^2- 6$.

torisob [31]

Answer:

a1=2 and r=-1

Explanation:

"A geometric series is a series with a constant ratio between successive terms".

Here, we can observe that the first term 'a' is '2'.

And the common ratio 'r' =

Therefore, the first term 'a' is 2 and common ratio 'r' is '-1'.
