wallpaper is sold in rolls that are 2 feet wide what is the minimum length you would need to purchase to cover the wall and 60 f

vredina [299]

Answer:

Step-by-step explanation:

Let the wallpaper be a rectangle

Area of a rectangle = Length * Width

A = LW

Perimeter P = 2L+2W

If the wallpaper is sold in rolls that are 2 feet wide, then the width is 2 feet, to get the length, substitute W = 2 and P = 60 into the formula for calculating the perimeter of a rectangle.

60 = 2L + 2(2)

60 = 2L + 4

2L = 60-4

2L = 56

L = 56/2

L = 28

<em>The minimum length that will be purchased to cover the wall is 28 feet</em>

Suppose that Ayumi rolls a pair of fair six-sided dice. Let A be the event that the first die lands on 2 and B be the event that

Tanya [424]

Answer:

$\frac{1}{6} ,\frac{1}{6} ,\frac{1}{36}\,,\,independent$

Step-by-step explanation:

Given: Let A be the event that the first die lands on 2 and B be the event that the second die lands on 2.

To find:

P(A), the probability that the first die lands on 2

P(B), the probability that the second die lands on 2

P(A and B): the probability that the first die lands on 2 and the second die lands on 2

Solution:

Probability refers to chances of occurrence of some event.

Probability = number of favourable outcomes/total number of outcomes

Sample space = $\left \{ 1,2,3,4,5,6 \right \}$

Total number of outcomes = 6

For P(A):

Number of favourable outcomes = 1

So,

$P(A)=\frac{1}{6}$

For P(B):

Number of favourable outcomes = 1

So,

$P(B)=\frac{1}{6}$

P(A and B) = $P(A)P(B)=\left ( \frac{1}{6} \right )\left ( \frac{1}{6} \right )=\frac{1}{36}$

Yes, A and B are independent events as happening of each of the event does not depend on the other.

The correct answer is option C.

Step by step solution is listed below.

$(4 x^{3}+8x)( x^{2} -1) \\ \\ 
 =4 x^{3}(x^{2} -1)+8x(x^{2} -1) \\ \\ 
=4x^{5}-4 x^{3}+8 x^{3}-8x \\ \\ 
=4 x^{5}+4 x^{3}-8x$
