Answer:

732 yd³

Step-by-step explanation:

This is a non-rectangular prism, so we have to <em>multiply the base times the height</em> (instead of multiplying length*width*height).

1. Base: trapezoid area equation: (b₁ + b₂)h/2 (b = bases of the trapezoid, h = height of the trapezoid)

Plug in: (11 + 4)6.1/2

Add: 15*6.1/2

Multiply + divide: <em>45.75 yd²</em>

2. Multiply with height: 45.75 * 16 = 732 yd³

When finding the margin of error for the mean of a normally distributed population from a sample, what is the critical probabili
svlad2 [7]

Critical probability is the essentially cut-off value. The critical probability when the confidence level of 58% is 0.79.

<h3>What is the critical probability?</h3>

Critical probability is the essentially cut-off value that defines the region where the test statistic is unlikely to lie.

As it is given that the confidence level is 58%. therefore, in order to calculate the critical probability, we need to calculate the margin of error within a set of data, and  it is given by the formula

\rm Critical\ Probability, (P*) = 1-\dfrac{\alpha }{2}

where the value of the α is expressed as,

\alpha= 1 -\dfrac{\rm Confidence\ interval}{100}

Now, as the confidence interval is given to us, therefore, the value of the alpha can be written as,

\alpha= 1 -\dfrac{\rm 58\%}{100} = 0.42

Further, the critical probability, assuming a confidence level of 58% is,

\rm Critical\ Probability, (P*) = 1-\dfrac{\alpha }{2}\\\\\rm Critical\ Probability, (P*) = 1-\dfrac{0.42}{2} = 0.79

Hence, the critical probability is 0.79.

Solve the equation, 4 - (x + 1) = 6.<br><br> x = -3<br> x = 3<br> x = -9<br> x = 9
Vinvika [58]

Answer:

Step-by-step explanation:

The negative in front of the parenthesis changes the signs of the numbers and variables inside the parenthesis. We can rewrite as

4 - x - 1 = 6 and

3 - x = 6 so

- x = 3 and

x = -3
