Answer:
x = 22
Step-by-step explanation:
158 + x + 148 + 32 must sum up to 360 as this is a quadrilateral. Thus:
x + 338 = 360.
Subtracting 338 from both sides, we get x = 22
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
The equation to calculate the average rate of change is: y/x
y = f(x2) - f(x1)x = x2 - x1
x1: 1 (The smaller x value. It can be any number)x2: 2 (The larger x value. It also can be any number)f(x1): The value when you plug x1 into the function.f(x2): The value when you plug x2 into the function.
If we know this, the variables for this problem are assuming the function is 10(5.5)^x:
x2: 2x1: 1f(x2): 10(5.5)^(2) = 302.5f(x1): 10(5.5)^(1)= 55
This means:y = 302.5 - 55 = 247.5x = 2 - 1 = 1
Remember: the equation for avg rate of change is y/x
So, our average rate of change for the function on the interval [1,2] is 247.5 (y/x = 247.5/1)
7 and 1 for 6
and 4 and 4 make 8 right?
Answer:
Step-by-step explanation:
Jenny planned to solve 2/3 of homework
On Saturday she solved 28 problems, which is 7/8 of the planned number
<u>Planned number is:</u>
- 28 : 7/8 = 28 * 8/7 = 32 problems
<u>Jenny's homework was:</u>
- 32 : 2/3 = 32 * 3/2 = 48 problems
