andreev551 [17]
The possible digits are: 5, 6, 7, 8 and 9. Let's mark the case when the locker code begins with a prime number as A and the case when <span>the locker code is an odd number as B. We have 5 different digits in total, 2 of which are prime (5 and 7).

First propability:
</span>P_A=\frac{2}{5}=40\%
<span>
By knowing that digits don't repeat we can say that code is an odd number in case it ends with 5, 7 or 9 (three of five digits).

Second probability:
</span>P_B=\frac{3}{5}=60\%

Parking in a student lot costs $2 for the first half hour and $1.75 for each hour thereafter. A partial hour is charged the same
Masteriza [31]

An easier way to think of this problem is just keep adding for each additional hour: 


0.5 hours --> $2 

1.5 hrs --> $3.75 

2.5 hrs --> $5.50 

3.5 hrs --> $7.25 


and since you can only spend $7, the maximum time is 2.5 hours

How do you calculate the mean of a number?

Answer:

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Find a solution to the linear equation - 2x – 2y = 8 by filling in the boxes with a valid value of x and y.
adoni [48]

Answer:

-2(-4)-2(0)=8

Step-by-step explanation:

Given

2x - 2y = 8

Required

Gaps: -2( )-2( )=8

<em>Fill in in the gaps</em>

The are numerous solutions to this.

One of them is:

Assume y = 0.

So, we have:

-2x - 2*0 = 8

-2x - 0 = 8

-2x = 8

Divide through by -2

\frac{-2x}{-2}= \frac{8}{-2}

x= -4

Fill in the gaps with these values of x and y respectively:

Hence; one solution is: -2(-4)-2(0)=8
