Answer:

The area to the right of 2.120 is 0.0250 rounded to 4 decimal places

Step-by-step explanation:

We are required to find $P(t>2.120)$

To find this area we have to use the t distribution. Also we can use technology like excel to find the area to the right of 2.120.

The excel function is:

=TDIST(2.120,16,1)=0.0250

Where:

2.120 is the value of the test statistic

16 is the degrees of freedom

1 denotes the one tailed.

Therefore, the area to the right of 2.120 is 0.0250

In the given situation, the ratio of the perimeters of two rectangles is 4 to 7. The perimeter of the larger rectangle is 42 inches.Now, let's find the perimeter of the smaller.Let's solve for the answerRatio and formula:=> 4 : 7 = X = 42, where x is the unknown perimeter of the smaller rectangle=> 4 * 42 = 168 / 7 = 24Thus the answer is letter D. 24 inches is the parameter of smaller rectangle.<span>
