Answer:

x=10.58

Step-by-step explanation:

To find the side length of a right triangle, you can use the Pythagorean theorem.

The Pythagorean theorem is a^2+b^2=c^2

the c is the hypotenuse of the triangle, so 16.

the a and b are the other sides of the triangle, so x and 12.

Therefore, x^2+12^2=16^2

       now you can solve the equation.

x^2+144=256

      -144    -144

x^2=112

now you have to square root both sides of the equation.

\sqrt{x^2} =\sqrt{112}

x=10.58

Luba_88 [7]

Answer:

The answer is false

Step-by-step explanation:

In a sample above 30 obs  like this the confidence interval is defined as

X+- t* (s/sqrt(n)) where X is the mean t the tvalue for a given confidence level, n the size of sample and s standar deviation.

To find de appropiate value of t we must see the T table where rows are degrees of freedom and columns significance level

The significance is obtained:

significance = 1 - confidence level = 1 - 0.9 = 0.10

Degrees of freedom (df) for the inteval are

df = n - 1 = 18 - 1 = 17

So we must look for the value of a t with 17 values and significance of 0.10 which in t table is 1.740 not 1.746 ( thats the t for 16 df)

Can someone help me a still don't get this concept???
Flauer [41]

Well, if y = x - 5, then we calculate:

when x = -1 then y = -1 -5 = -6

when x = 0 then y = -5

when x = 1 then y = 1 - 5 = -4

when x = 2 then y = 2 - 5 = -3

Hope this helps!
