Answer:
5/6
Step-by-step explanation:
Perpendicular lines just have the opposite slope.
Using a t-distribution calculator, it is found that the critical value of the test statistic t is 
.
<h3>How to find the critical value of a t-test?</h3>
- The critical value is found using a calculator.
The inputs are:
- The amount of degrees of freedom, which is one less than the sample size.
In this problem, we have a<u> lower(left-tailed) test, with 10 - 1 = 9 df and a level of significance of 0.1</u>, hence the critical value is .

The two consecutive integers are 2 and 3
<em><u>Solution:</u></em>
Let x and x + 1 are the two consecutive integers
Let "x" be the smallest integer
Let "x + 1" be the larger integer
<em><u>Given that, sum of 2 consecutive integers is one less than 3 times the smaller integer</u></em>
Therefore,
sum of 2 consecutive integers = one less than 3 times the smaller integer
sum of 2 consecutive integers = 3 times the smaller integer - 1
x + x + 1 = 3(x) - 1
2x + 1 = 3x - 1
3x - 2x = 1 + 1
x = 2
Thus the smaller integer = x = 2
Larger integer = x + 1 = 2 + 1 = 3
Thus the two consecutive integers are 2 and 3
Answer:
The answer D) because you add the same variable's which leave you with 2x-4
Step-by-step explanation:
first do positive 7-4-1=2. after that do the variables which get you 2x+1x+1x=4x
<span>The number is 470, 000
To explain further:
An example is
14,494 </span>
<span>To round off the height value to the nearest thousand we can use the expanded from to clarity the position of numbers which is: </span>
<span>10, 000 = ten thousand </span>
<span>4, 000 = thousands </span>
<span>400 = hundreds </span>
<span>90 = tens </span>
<span>4 = ones </span>
<span>Here we can notice than four thousand is the value where the nearest thousands is placed. Hence we can round off the number of 14, 494 into 14, 000. Notice 0-4 rounding off rules.<span>
