The equivalent expression to 0.2(3x-4) is 0.6x - 0.8.

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

Given:

Expression: 0.2(3x-4)

Now, using the distributive property we have

= 0.2(3x-4)

= 0.2(3x)- 0.2(4)

= 0.6x - 0.8

Hence, the equivalent expression is 0.6x - 0.8.

Step-by-step explanation:

Each side equals 50ft. 5x+20=50

minus 20 on both sides

5x=30

divide by 5 on both sides

Answer:

P(Drive to school | Sophomore) = 0.07 (nearest hundredth)

Step-by-step explanation:

A probability is conditional if it depends on what has already happened.

P(Drive to school | Sophomore) means:

The probability that a student "drives to school" given that they are a "sophomore".

Using the conditional probability formula:

P(B | A) = P(B ∩ A) ÷ P(A)

⇒  P(Drive to school | Sophomore) = P(Drive to school ∩ Sophomore) ÷ P(Sophomore)

Reading from the two-way table, there are 2 people that drive to school AND are a sophomore.

Adding all the values in the table gives us the total number of students: 2 + 13 + 25 + 25 + 20 + 5 + 3 + 2 + 5 = 100

⇒ P(Drive to school ∩ Sophomore) = 2/100 = 0.02

Adding all the values in the sophomore line of the table gives us the total number of sophomores:  2 + 25 + 5 = 30

⇒ P(Sophomore) = 30/100 = 0.3

Now plug these values into the formula:

P(Drive to school | Sophomore)  = P(Drive to school ∩ Sophomore) ÷ P(Sophomore)

P(Drive to school | Sophomore)  = 0.02 ÷ 0.3

                                                      = 1/15

                                                      = 0.07 (nearest hundredth)

Answer:

m = 1.53

Step-by-step explanation:

d=m/v

5.1=m/0.3

m = 5.1 * 0.3

m = 1.53

{ changing sides, changes the sign + to - and - to + }

{ changing side, changes * to / and / to * }

Answer:

Range: All real numbers or X∈R

Step-by-step explanation:

1/5 because there is 5 friends and you will each have 1 percent of probabality.

The probability of being chosen on Monday is 1/5, and the probability of Terry being chosen on Tuesday is 1/4, the probability of both events happening is 1/20.

To find the probability that you are chosen on Monday and Terry is chosen on Tuesday,

Calculate the probability of each event separately and then multiply the probabilities.

Probability of you being chosen on Monday:

There are 5 names in the hat, including yours. Since you and 3 friends are drawing one name randomly, the probability of you being chosen on Monday is 1 out of 5.

Probability of you being chosen on Monday = 1/5

Probability of Terry being chosen on Tuesday:

After you were chosen on Monday, there are now 4 names left in the hat, and one of them is Terry's. So, the probability of Terry being chosen on Tuesday is 1 out of 4.

Probability of Terry being chosen on Tuesday = 1/4

Now, to find the probability of both events happening, we multiply the probabilities:

Probability of you on Monday AND Terry on Tuesday = (1/5) * (1/4) = 1/20

Therefore, the probability that you are chosen on Monday and Terry is chosen on Tuesday is 1/20.

The solution is, angle A is opposite of BC.

It can be mentioned as, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

from the given figure, we get,

here, ABC is a triangle.

now, we have to find the side which is opposite to angle A.

so. we get,

Here, we want to get the side that is opposite of the angle marked A

Looking at the given triangle, we can see that the given angle is opposite the side labelled BC.

Thus, we can say that the angle marked A which lies on vertex A is opposite the side marked BC.
