11.)-If PQRS is a parallelogram, find the values of x and y.
defon

Step-by-step explanation:

For no. 11

13x + 15 = 19x - 9 ( being opposite sides of parallelogram)

19x - 13x = 15 + 9

6x = 24

x = 4

Also,

4y + 7 ° + 10y - 37° = 180° { being co-interior angles }

14y - 30° = 180°

14y = 210°

y = 210° / 14

y = 15°

For no. 12

5x + 38° = 8x - 19° { being opposite angles of parallelogram }

8x - 5x = 38° + 19°

3x = 57°

x = 19°

Hope it will help :)

A wheel rotates 15 times each minutes. How many degrees will it rotate in 1 second of time?​
liubo4ka [24]

Answer:

In 1 second it Rotates 15× 360 / 60

Step-by-step explanation:

Wheel Rotates 15 times in 60 seconds

This implies that the wheel completes

15 × 360 degrees in 60 seconds

therefore,

In 1 second it Rotates 15× 360 / 60

=> 15×6 = 90 °

in 12 seconds , 12×90 = 1080°.

De mediaan is 6

Het gemiddelde is 6

Standaarddeviatie is 3,32

Variantie is 11

Aantal werknemers is 13

Step-by-step explanation:

Taak.1 12 medewerkers is gevraagd naar het aantal verlofdagen. Hier zijn de antwoorden: 2, 5, 14, 3, 6, 5, 8, 2, 5, 4, 6, 8. Geef de dominante en de mediaan. Taak 2 13 medewerkers is gevraagd naar het aantal vakantiedagen. Hier zijn de antwoorden: 2, 4, 14, 3, 6, 7, 8, 2, 5, 4, 6, 8, 9. Geef de dominante en mediaan.

Taak. 1 12, wordt de mediaan gegeven door

2, 5, 14, 3, 6, 5, 8, 2, 5, 4, 6, 8 herschikken, we krijgen

2, 2, 3, 4, 5, 5, 5, 6, 6, 8, 8, 14

Daarom is de mediaan 5 en het gemiddelde 5,67

Taak 2 13

2, 4, 14, 3, 6, 7, 8, 2, 5, 4, 6, 8, 9 herschikken, we krijgen

2, 2, 3, 4, 4, 5, 6, 6, 7, 8, 8, 9, 14

De mediaan is het zevende nummer in de rij = 6

Het gemiddelde is ook = 6

Standaarddeviatie = 3,32

Variantie = 11

Aantal werknemers = som van frequentie of aantal gegevens = 13.
