jolli1 [7]

Answer: Our required probability is 0.18.

Step-by-step explanation:

Since we have given that

Probability that husband is on the internet = 10% = 0.10

Probability that husband is not on the internet = 1-0.10 = 0.9

Probability that wife is on internet given that husband is on internet = 40% = 0.40

Probability that wife is on internet given that husband is not on internet = 20% = 0.20

Probability that wife is on internet is given by

$0.1\times 0.4+0.9\times 0.2\\\\=0.04+0.18\\\\=0.22$

So, Probability that the husband is also on internet given that wife is on internet is given by

$\dfrac{P(\text{wife and husband both on internet)}}{P(wife\ on \ internet)}\\\\=\dfrac{0.4\times 0.1}{0.22}\\\\=\dfrac{0.04}{0.22}\\\\=0.18$

Hence, our required probability is 0.18.

Answer:

Standard Form: x^2 + 10x + 24

Step-by-step explanation:

In order to solve this, you would have to find the area of ALL of the shapes provided:

Blue Shape: The area is x^2 (X squared)

Green Shape: Area is 6x

Purple Shape: Area is 4x

Orange Shape: 24

The make the area of the whole shape

Top would be x^2 + 6x

While side would be 4x + 24

Now you can find the area!

x^2 + 6x +4x + 24

x^2 + 10x +24

An artist uses a 3-foot piece of wood to carve statues she uses 1/6 foot pieces of wood for each statue how many statues can be

Alexxandr [17]

Answer:

18

Step-by-step explanation:

Dimension of piece of wood = 3 ft

Dimension of piece of wood used for one statue = $\frac{1}{6}$ ft

To find:

Number of statues that can be made from all the wood ?

Solution:

To find the total number of statues that can be carved from the given piece of wood, we need to divide the dimensions of given piece of wood with the piece required to carve one statue.

Formula:

$\dfrac{a}{\frac{b}{c}} = \dfrac{a\times c}{b}$

Number of statues that can be made:

$\dfrac{3}{\frac{1}{6}}\\\Rightarrow \dfrac{3\times 6}{1}\\\Rightarrow \bold{18}$

Therefore, 18 number of statues can be made.
