For number 1: .5/.25 = Unknown/120.

For number two add all the letters in ridiculous: all chances would be 1/10 except "I" and "u" there are two so chances are 2/10 or 1/5

Answer:

(0.63789 ; 1.38211 )

Given that:

Mean, xbar = 1.01

Standard deviation, s = 0.29

Sample size, n = 7

Confidence interval : xbar ± margin of error

Margin of Error = Tcritical * s/sqrt(n)

Degree of freedom (df) = n - 1 = 7 - 1 = 6

Hence Tcritical = 3.143

Margin of Error = 3.143 * 0.29/sqrt(6)

Margin of error = 0.37211

Lower boundary = (1.01 - 0.37211) = 0.63789

Upper boundary = (1.01 + 0.37211) = 1.38211

(0.63789 ; 1.38211 )

What is the reason for each step in the solution of the equation?<br><br> −6x+7x+14=3

sertanlavr [38]

-6x + 7x + 14 = 3
First, you add the variables x between each other so we can have one number with variable x:
x + 14 = 3
Then, subtract 14 from each side to get the variable x alone of a side, and its value on the other side:
x + 14 - 14 = 3 - 14
x = - 11

You can re-check your answer (very important):
-6x + 7x + 14 = -6(-11) + 7(-11) + 14 = 66 - 77 + 14 = -11 + 14 = 3
The answer has been approved.

Hope this Helps! :)
