Answer:
31.4
Step-by-step explanation:
1. Multiply r*2 to get d
5*2=10
2. Multiply d*pi to get C
10*pi=31.159265
Answer:
Step-by-step explanation:
Answer:
The integers are 11 and 12.
Step-by-step explanation:
Let x be the greater integer, then the lesser is x - 1, so:
2x = 3(x -1) - 9 Distribute the 3:
2x = 3x - 3 - 9 Subtract 3x from both sides:
-x = -3 - 9
-x = -12
x = 12.
Answer:
The most appropriate inference procedure for the investigation is;
a. A linear regression t-interval for the slope
Step-by-step explanation:
Given that the slope of an horizontal line is zero, we have that there is no change in the y (dependent) variable when there is a change in the x-variable, therefore, it is important to find the true relationship between the two variables, 'x', and 'y'
The confidence interval of the slope is calculated and analyzed to determine if it excludes or includes, 0, such that, if the confidence interval exclude 0, then, it is unlikely that the slope is 0, therefore, there the relationship between the variables, 'x', and 'y' is significant
Therefore, a linear regression t-interval for the slope is most appropriate.
Keywords:
<em>Result, sum, number
</em>
For this case we must give the result obtained by adding three times the number 15 with four times the number 2. For this we have, be "x" the result obtained when making the addition:
What is equivalent to:
Thus, the sum of three times 15 and four times 2 is 53.
Answer:
The sum of three times 15 and four times 2 is: 53.
