Answer:
She has enough but too much, if she uses 214 plus the 1 cup she borrowed out of 412 cups of oats for a recipe that calls for 212 then she'll have 413 or 3 cups left separately, she won't need any more
Answer:
gasgas....
Step-by-step explanation:
The answer to this is 2.
There are a number of proofs to this. Here, we use Euclidean geometry with trigonometry. If we let the center of the circle to be O.
Then, we have the following equations for the angles
CEO = OED = 90
Since, CO = OD because they're radii of the circle, then
ΔCOD is an isosceles triangle and
OCE = ODE
CE + DE = CD
dividing the whole equation by DE
CE/DE + 1 = CD/DE
Using trigonometric functions:
CE = OC cos OCE and
DE = OD cos ODE
Substituting.
OC cos OCE / OD cos ODE + 1 = CD/DE
Since, OCE = ODE,
cos OCE = cos ODE
The equation would be reduced to:
1 + 1 = CD/DE
CD/DE =2
Answer:
students' ratings of their professors' performance on a five-point scale ranging from poor to excellent
Step-by-step explanation:
There are four type of scales in mathematics. They include:
1. Nominal scale : they do not measure quantity. they are used to classify a population into two or more scales that are exhaustive and mutually exclusive. e.g. classifying a population based on gender, naming the different car brands seen in a school's parking lot
2. Ordinal scale : this scale measures ranks a population from best to worst or from least to most. e.g. ranking the participants of a race based on their performance
3. Interval scale : this scale has the property of order and equal intervals. Zero is not meaningful.
Interval scale is used when the difference between the numbers are meaningful. e.g. students' ratings of their professors' performance on a five-point scale ranging from poor to excellent Here a child who is scored 1, did very poorly and a child scored 5, performed excellently well.
4. Ratio scale : this scale has the property of order, a meaningful zero and equal intervals.
