5/3 or 1 2/3 the first one is the answer but the second answer is just simplified :)
Why is important to maintain an assessment’s validity, reliability, and equity in testing?
Answer: Reliability refers to the degree to which scores from a particular test are consistent from one use of the test to the next. ... Ultimately then, validity is of paramount importance because it refers to the degree to which a resulting score can be used to make meaningful and useful inferences about the test taker
Part A:
The area of the rectangle will be the length times the width, so 4•(x+3). Using distributive property, you'll multiply every term inside the parentheses by 4.
The area of the rectangle can be expressed by 4x+12.
Part B:
Multiply 4•2 and (x+3)•2, then multiply them together.
8(2x+6) Now use distributive property to find your answer simplified.
16x+48 is your answer
Answer:
Step-by-step explanation:
Since I cannot see the image I cannot solve it entirely so you will have to figure some parts out, but I will try to help you as best as I can :)
So basically the formula for volume is:
L*W*H
So the volume of each cube is 1/8 cubic centimeters
Now, to solve you problem you must find the number of cubes for the length, width and the height
Let's call the length x, the width y and the height z
Then use the volume formula to find the number of 1/2 cm cubes in the figure
So xyz is the number of 1/2 cubes in the figure
To find the volume in cubic centimeters you have to multiply xyz by 1/8
That will be the volume
