Answer:
12
Step-by-step explanation:
A constant in an expression is the number that is not attached to any variable, and this includes the sign that comes with the number.
0.05m +12
In the expression above, m is the variable thus 0.05 is known as the coefficient of m instead of a constant. Coefficients are numbers that are multiplied to variables.
+12, which can simply be written as 12, is not multiplied to any variable and is thus the constant.
The value of the number 12 will not change no matter the value of m. The fact that the value stays the same makes it a constant.

River C : 200 + x
River D: x
200 + x + x = 5,540
combine like terms
200 + 2x = 5,540
subtract 200 from both sides
2x = 5,340
divide both sides by 2 to isolate the variable
x = 2, 670
River C: 200 + x = 200 + 2,670 = 2,870
River D: x = 2,670
2,870 + 2,670 = 5,540
Answer:
-4 ,-2, 0
Step-by-step explanation:
2n-6
1st term: n=1
2(1) -6 = 2-6 =-4
2nd term: n=2
2(2) -6 = 4-6 =-2
3rd term: n=3
2(3) -6 =6-6 =0
Answer:
The sample size is too small and will show a large variation.
The sample size is too small and can lead to false inferences.
A larger sample will give more reliable information.
Step-by-step explanation:
-In statistical sampling, sample size is of critical importance.
-A large sample size increases the accuracy of mean values as it eliminates or flattens out outliers.
-A large sample size also leads to a lower margin of error as the confidence level increases.
-The is greater precision when a larger sample size is used.
Option I: 10 candy bars for $6.75
<span>6.75/10 = 0.68 </span>
<span>Option II: 12 candy bars for $7.25 </span>
<span>7.25 / 12 = 0.60 </span>
