In this triangle, what is the value of x? Enter your answer, rounded to the nearest tenth, in the box. x = yd A right triangle w

Eduardwww [97]

Answer: 47.4 yds.

So, if this is a right triangle then you will have a hypotenuse, opposite Leg, and the adjacent. I get it that the first Leg is X an the other is 40 and the hypotenuse is 62.

C=62

A=40

B= X

We gonna use the Pythagorean theorem to solve this problem

C^2=a^2+b^2

62^2=40^2+x^2

x^2 = (62^2) -(40^2)

x^2= 3844-1600

x^2= 2244

x= 47.3708771293

Find the critical value t for the confidence level c= 0.98 and sample size n=7.

kenny6666 [7]

Answer:

The critical value is T = 3.143.

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 7 - 1 = 6

98% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 6 degrees of freedom(y-axis) and a confidence level of $1 - \frac{1 - 0.98}{2} = 0.99$ . So we have T = 3.143.
