Answer:
8z+5
Step-by-step explanation:
Let's split the expression into two terms- z and... not z :)
3z+5z=8z
Why? it's just 3+5 with z tacked on the end
14-9=5
simple math :)
put it together to get
8z+5
all done!

#1 m=7/4 the whole equation would be y=7/4x + 3/2
Rate x time = distance
25 x 35/60 = distance (35/60 is 35 minutes out of an hour- 60 minutes)
25/1 x 7/12 = distance (I put the 25 over 1 and reduced 35/60)
175/12 ≈ 14.58 miles
Notice that the time had to be in a fraction of an hour in order to do this.
Answer:
-1 1/3
Step-by-step explanation:
To find the mean, add up all the numbers
(-4+-3+-1+-1+0+1) =
-8
Then divide by the number of terms
-8/6
-4/3
-1 1/3
Answer:
The difference between the sample percentage and the population percentage is likely to be less than 4 percent
Step-by-step explanation:
The margin error is the difference between the values of the sample analyzed and the actual population. In reality, the result of the sample analyzed will be different from the actual result. This can be due to approximation error or human error. However, the difference in the two results should not be more than the allowable limit.
