Answer:
Correct option is A
Step-by-step explanation:
Given some statements we have to choose the correct statement.
A. Square BCDF is a rectangle.
As we know, all the properties of rectangle satisfied by square. Therefore, we say that all squares are rectangles. hence, Square BCDF is a rectangle is true statement.
B. Rectangle GJKM is a square.
As explained in above, all the properties of rectangle satisfied by square but its converse is not true i.e all rectangles are not square. Hence, Rectangle GJKM is a square is not always true.
C. Quadrilateral STPR is a trapezoid.
All the properties of trapezoid are not satisfied by all quadrilateral hence, not always true.
D. Parallelogram ABCD is a rhombus
All the properties of rhombus are not satisfied by parallelogram like all sides of rhombus are congruent but parallelogram has only opposite sides congruent. hence, not always true.
Correct option is A.
Answer:
Step-by-step explanation:
Answer:
For the first on it is 4 out 52 because there are 4 kings in a deck of 52
For the second on it could be 3 out of 51 because you took out one king which means there are 3 kings left and then by taking that king out you are left with 51 cards

Answer:
a. Alice’s claim is correct.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval is inversely proportional to the sample size. This means that a smaller sample size leads to a smaller margin of error and a narrower interval, while a larger sample size leads to a larger margin of error and a wider interval.
Alice claims that a sample size of 25 will produce a narrower interval
25 > 20, so smaller margin of error and narrower interval, which means that Alice is correct.
Desmond claims that a sample size of 15 will produce a narrower interval.
15 < 20, so larger margin of error and wider interval, which means that Desmond is wrong.
So the correct answer is given by option a.
