Answer:
1:9
99:11
9:11
1:99
Step-by-step explanation:
I pretty sure mb if it's wrong but Im pretty sure its right
A(n)=a(1)+d(n-1), d=a(16)-a(15)=-5-(-53)=48
a(15)=a(1)+d*(15-1),
-53=a(1)+48*(15-1),
a(1)=-53-48*14= -725
a(n)=-725+48(n-1)
Compare each place value. It's kind of hard to explain without examples...
Answer:
33.6
Step-by-step explanation:
The following data set shows the numbers of hours that employees at a certain shop worked in one week
34 36 32 40 39 17 35 33 36 34
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.
Hence,
Answer:
8x +5
Step-by-step explanation:
The sum is found by combining "like" terms—those that have the same arrangement of variables.
The first expression, 2x +6, has terms 2x and 6.
The second expression, 6x -1, has terms 6x and -1.
In each case, the first term listed is first-degree in the variable x. These are "like" terms, so can be added:
... 2x +6x = (2+6)x = 8x
The second term listed in each case is a constant. These are "like" terms, so can be added:
... 6 + (-1) = 5
Then the sum of the given expressions is the sum of the results from adding like terms:
... 8x + 5
