Answer:
<u>3.14 cm²</u>
Step-by-step explanation:
<u>Given :-</u>
Diameter = 2 cm
<u>To Find :-</u>
Area
<u>Formula Required :-</u>
Area (circle) = πr²
<u>Solving :-</u>
Area = 3.14 x 1 x 1
= 3.14 x 1
= <u>3.14 cm²</u>
<u>Solution :-</u>
<u>3.14 cm²</u>
Answer: C
Step-by-step explanation: i’m doing the test too
Using the formula:
A1/(1 - r)
Substituting the values:
<span>= 880 /(1 - 1/4) </span>
<span>= 880 / (3/4) </span>
<span>= 1173.33 </span>
Answer:
below 15 times
Step-by-step explanation:
If the numbers on the spinner are 1, 2, 3, 4, 5, 6 (six numbers) the even numbers are 2, 4, 6 ( three numbers) than 3 out of 6 numbers on the spinner are even.
If Jane will spin the spinner below 30 times the is expected that less than half of the time 30/2 = 15 times will be an even number.
By definition, when a test or technique measures what it intends to, it is valid.
The answer is option A.
The criterion-related validity of a take-a-look is measured by the validity coefficient. Its miles said as a number between zero and 1.00 that indicates the significance of the relationship, "r," among the take a look at and a measure of task overall performance (criterion).
Reliability and validity are both approximately how nicely a technique measures something: Reliability refers to the consistency of a measure (whether or not the consequences can be reproduced below identical situations).
Validity refers back to the accuracy of a measure (whether or not the results really do constitute what they may be speculated to a degree).
