Answer:
yeah b
Step-by-step explanation:
took the test
We can set the 2nd equation to y that way we have something to solve for
First we solve our first equation by moving the one to the other side
Then we divide by 3 on each side
So now we can plug 4 into the x's of the 2nd equation
Calculate first the common difference of the arithmetic sequence,
d = (-29 - -4)/(8 - 3) = -5
The first term is calculated through the way below,
a1 = -4 + 5 + 5 = 6
Thus, the first term of the arithmetic sequence is 6 and the common difference is -5.
Answer:
The total number of ways are 168.
Step-by-step explanation:
Consider the provided information.
There are 7 junior and 3 senior coders in her group.
The first project can be written by any of the coders. The second project must be written by a senior person and the third project must be written by a junior person.
For second project we have 3 choices and for third project we have 7 choices.
Now there are 2 possible case:
Case I: If first and second coder is senior, then the total number of ways are:
Case II: If first and third coder is junior, then the total number of ways are:
Hence, the total number of ways are: 42+126=168
Answer:
50%
Step-by-step explanation:
half of 30 is 15
half= 50
