The upper quartile of a set of data is a number that . a) separates the bottom half of the data set from the upper half. b) finding the mean of the dara set remaining after removing the lower half/. c) separates the lower quarted of the data set from the upper three quarters. d) separates the lower three quartes of the data set from the upper quarter.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
