Marlon asks a friend to think of a number from 5-11. What is the probability that marlins friend will think of the number 9

Tju [1.3M]

Answer:

14.29% probability that Marlon's friend will think of the number 9

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

There are 7 numbers from 5 to 11(5,6,7,8,9,10,11)

9 is one of them

So

$p = \frac{1}{7} = 0.1429$

14.29% probability that Marlon's friend will think of the number 9

Issa jogged 2/3 of the way home from school .Then he was tired ,so he walked the remaining 3,200 m how many kilometers did he tr

MissTica

Answer:

9.6 km

Step-by-step explanation:

Issa jogged 2/3 of the way home from school.

Then he was tired, so he walked the remaining 3200 m.

In other words, the remaining 3200 m is 1/3 of the way from school to home.

Let the distance from school to home be x. Therefore:

$\frac{1}{3} * x = 3200\\\\=> x = 3200 * 3 \\\\x = 9600 m$

Therefore, from school to home he traveled 9600 m.

To put this is kilometres:

1000 m = 1 km

9600 m = 9600 / 1000 = 9.6 km

He traveled 9.6 km from school to home.

Factor the expression. 16j2 + 24j + 9

rjkz [21]

Option C: $(4 j+3)^{2}$ is the correct answer.

Explanation:

The given expression is $16 j^{2}+24 j+9$

We need to factor the expression.

Let us rewrite the expression as

$(4j)^{2}+24 j+(3)^2$

Also, we can rewrite the term $24j$ as $2(4)(3)j$

Thus, we have,

$(4j)^{2}+2(4j)(3)+(3)^2$

Hence, the equation is of the form,

$(a+b)^{2}=a^{2}+2 a b+b^{2}$

where $a=4 j$ and $b=3$

Hence, the factor of the expression can be written as $(4 j+3)^{2}$

Thus, the factored expression is $(4 j+3)^{2}$

Therefore, Option C is the correct answer.
