You need to split the shape into simpler shapes so you would get a rectangular prism and a triangular prism finding the volume is pretty straightforward the formula is
Volume of a triangular prism = area of base triangle × height
The formula for finding the volume of a rectangular prism is the following: Volume = Length * Height * Width, or V = L * H * W.
After solving for this you would just have to add the 2 shapes volume together tie get the volume of the composite figure
Finding the surface area is also pretty simple since it would only require you to know the formulas
S = 2(lw + lh + wh) to find the surface area of a rectangle or prism
A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.
And by adding the two surface areas of the shapes you can get the surface area of the composite figure but remember to subtract the top face of the rectangular prism and the bottom face of the triangular prism
Hope this helps <3

A 99% confidence interval for the mean sodium content in Oriental Spice Sauce is,
First, compute t -critical value then find confidence interval.
The t critical value is,
The sample size is small and two-tailed test. Look in the column headed 
and the row headed in the t distribution table by using degree of freedom is,
d . f . =n-1
=170-1
=169
The t critical value is 2.605 .

Answer:
Step-by-step explanation:
When subtracting fractions with the same denominator (bottom number[s]) you can treat the numerators (top number[s]) like subtraction with whole numbers.
is equal to -12. Therefore,
will equal 
. But we're not there yet - this fraction can be simplified. We need to find the GCF, or greatest common factor, of -12 and 9. This would be another number that can be divided evenly into these two numbers. The first possible GCF that comes to mind is 3. Let's test that out:
It works! Now we can use this information to simplify the fraction. We replace -12 with -4 and replace 9 with 3. This gives us our final answer, .
Alright, subtract 2x from both sides, then subtract 6 both sides.
You'll get 4x=-16
Divide -16 by 4
X=-4
