Subtract sides -7
Thus ;
So the correct answer is (( A )) .
Answer:
E
Step-by-step explanation:
A linear equation is in the form of: 
, where m is the slope and b is the y-intercept.
m is the slope and it's given, which is -6
b is the y-intercept and it's given, which is 9
When we plug in to the form we get:
Answer:
360
Step-by-step explanation:
Given
Digits: 0 to 5
Required
Number of 4 digit passcode that can be generated.
First, we need to get the number of usable digits.
Digits 0 to 5 = 0,1,2,3,4,5
Number of digits = 6
To make a 4 digit passcode;
The first digit can be taken from any of 6 digits
The second digit, any of the remaining 5 digits
The third digit, any of the remaining 4 digits
The fourth digit, any of the remaining 3 digits
Number of passcode = 6 * 5 * 4 * 3
Number of passcode = 360
The answer is 0.24
To calculate this, a multiplication rule is used. The multiplication rule calculates the probability that both of two events will occur. In this method, the probabilities of each event are multiplied. Here we have two events:
1. The probability that the pianist will be a boy,
2. The probability that the alternate will be a girl.
So, let's calculate these probabilities:
There are in total 5 children:
2 boys + 3 girls = 5 children.
1. The probability that the pianist will be a boy is 2 boys out of 5 children, which is 2/5.
2. The probability that the alternate will be a girl is 3 girls out of 5 children, which is 3/5.
<span>The probability that the pianist will be a boy and the alternate will be a girl is:</span>
<span>2/5 </span><span>× 3/5 = 6/25</span>
<span>6/25 </span><span>× 4/4 = 24/100 = 0.24</span>
