Step-by-step explanation:

$area \: of \: garden = \pi {r}^{2} \\ = 3.14 \times {19}^{2} \\ = 1133.54 \: {ft}^{2} \\ number \: of \: bags = \frac{area \: of \: garden}{area \: covered\: by \: bag} \\ = \frac{1133.54}{32} \\ = 36 \: bags$

Quadrilateral LMNO is a parallelogram, and LM=24-9 and NO=y-2, find the value of "y" and the length of NO.

Slav-nsk [51]

Answer:

y = 7

NO = 5

Step-by-step explanation:

Let the side of the parallelogram LM and NO given be 2y - 9 and y - 2

Since LMNO is a parallelogram, hence;

LM = NO

2y - 9 = y - 2

2y - y = -2 + 9

y = 7

Since NO = y - 2

NO = 7 - 2

NO = 5

Eight teams are competing in the quarter-finals of a world football championship title. Three out of them are European.

zhuklara [117]

Answer: P(none of them Europeans play against each other)= $\frac{5}{14}$

Explanation:

Since there are 8 teams in which 3 are Europeans.

So, remaining 5 teams are not Europeans

We have to take 2 teams to pair up.

And we have a condition that neither of team is European.

So the favourable outcome = $\binom{5}{2}$

and the total outcomes= $\binom{8}{2}$

So, by using theprobability formula i.e.

P(E)= $\frac{\text{No. of favourable outcome}}{\text{Total no. of outcomes}}$

P(getting none of European team play against each other)= $\frac{\binom{5}{2}}{\binom{8}{3}}$

= $\frac{5\times4}{8\times7}$

= $\frac{5}{14}$
