Answer:
33000
Step-by-step explanation:
Substituting 250 for x and -120 for y, we get:
(250)^2 + 2(250) - (250)(120) = 62500 + 500 - 30000, or
32500 + 500, or 33000

- Height of cylinder = 21 cm
- Radius of cylinder = 24 cm
<u>Therefore, Volume :</u>
➙ V = πr²h
➙ V = ( 22 / 7 ) × ( 24 )² × ( 21 )
➙ V = ( 22 / 7 ) × 576 × 21
➙ V = ( 22 × 576 × 21 ) / 7
➙ V = 266112 / 7
➙ V = 38016

The volume of cylinder is it's density which tells us the amount by which it can be filled by any material or the the amount of material which can be immersed in it.
The Formula for volume of cylinder is given by :

- We have 52 cards in a deck of cards.
- We have 4 cards of the same number (4 jack, 4 aces...).
Probability of drawing a jack = 4/52
Probability of drawing a jack followed by an ace =(4/52)*(4/52)=0.00592

Answer:
To use a paired t-test
Step-by-step explanation:
t-tests are essentially tests carried out to compare two different groups to check if there is a major difference in their performances or results which may be related in certain characteristics.
A paired (correlated) t-test is used when there are matched pair of similar units or instances of repeated measurements.
In this case, Mary has to use a paired t-test because the samples (students) have high similarity in characteristics. The students in question has to be from the same class to test her hypothesis (similar characteristics).
