The number of freshmen entering college in a certain year is 621. What type of data is 621?
horrorfan [7]

Answer:  Third option is correct.

Step-by-step explanation:

Since we have given that

The number of freshmen entering college in a certain year = 621

It is considered as discrete data.

Since we know the definition of Discrete which refers to all types of data which take only numerical values.

Hence, Third option is correct.

Deposits into a bank account are represented by numbers. Withdrawals from the account are represented by negative numbers. Which
aleksley [76]

Answer:

The answer is (-$200) to the left

Step-by-step explanation:

Solution

It is assumed that when a number is positive,  it is a distance to the right, also when a number is negative, it is a distance to the left. If a positive number is referred to as  deposit to a bank account, then a negative number is a withdrawal from that bank account.

So, If a positive number means addition, then a negative number would also mean subtraction.

The amount that represents a withdrawal of less than $200 would be (-$200)

Value of x is 3.2x-9.6=38.4?
Svetradugi [14.3K]

Answer:

The steps that can be done to both sides of the equation is: Add 9.6, then divide by 3.2

Step-by-step explanation:

Solve the equation:

3.2x - 9.6 = 38.4

-First you add both sides 9.6:

3.2x -9.6 +9.6 = 38.4 +9.6

3.2x = 48

-Then, you divide both sides by 3.2:

\frac{3.2x}{3.2} = \frac{48}{3.2}

x=15
