. There are 10 beads in a bag. 5 beads are black; 3 beads are white and the rest are red. A bead is picked at random. Find the p

Bingel [31]

Part A

P(white) = (3 white)/(10 total) = 3/10

<h3>Answer: 3/10</h3>

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

Part B

10 total, 3 are white

10-3 = 7 are not white so they are either black or red

P(black or red) = 7/10

<h3>Answer: 7/10</h3>

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

Part C

Earlier in part B we calculated 7 beads that weren't white

This means P(not white) = P(black or red) = 7/10

They are the same probability just phrased slightly different ways.

<h3>Answer: 7/10</h3>

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

Part D

There aren't any blue beads (unless there's a typo somewhere). So the probability of picking not blue is 100% or we represent this as the value 1.

<h3>Answer: 1</h3>

Find the interval on which the curve of y equals the integral from 0 to x of 2 divided by the quantity 1 plus 3 times t plus t s

Hello,

$\dfrac{d^2( \int\limits^x_0 { \dfrac{2}{t^2+3t+1} } \, dt )}{dx^2} = \dfrac{d(\dfrac{2}{x^2+3x+1}) }{dx} \\

= \dfrac{-2(2x+3)}{(x^2+3x+1)^2}$

Let w=width and 4 + w=

kozerog [31]

Answer:

Part 1 : $w^2+4w-60=0$

Part 2 :

w=6

l = 10

Step-by-step explanation:

Part 1:

Let the width of the rectangle = w

Length of the rectangle = w + 4

Area of the rectangle is given as

60 Sq Yrds

$60=w(w+4)$

$60=w^2+4w$

$w^2+4w-60=0$

Hence this expression represents the area of the rectangle. Solving which for w will give us the width of the rectangle.

Part 2:

(w+10)(w-6)= 0

either (w+10) = 0

(w-6)=0

or both are zero

(w+10) = 0 ⇒ w = -10

not possible as the dimension can not be 0

(w-6)=0 ⇒ w=6

Hence the width is 6 yards

And thus the length will be 6+4 = 10 yards
