The population of a place was 56000. Next 5 years it is expected to rise by 50%. What will be the population in next 5 years?

Anna11 [10]

Answer:

84000 people

Step-by-step explanation:

So next 5 year wil be 56000 + 50%

56000 = 100%

50% = 56000 / 2

50% = 28000

56000 + 28000 = 84000

Event A: Spinning violet or yellow on the spinner.

OlgaM077 [116]

Answer:

$\sf P(A \cap B)=\dfrac{1}{4}$

Step-by-step explanation:

$\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}$

<u>Event A - spinning violet or yellow</u>

Assuming that the spinner has 4 different colors (red, orange, violet and yellow) - see attachment.

$\implies \sf P(A) = \dfrac{2}{4}=\dfrac{1}{2}$

<u>Event B - rolling an even number</u>

Assuming the number cube has 6 sides numbered 1, 2, 3, 4, 5 and 6. Therefore, the even numbers are 2, 4 and 6.

$\implies \sf P(B)=\dfrac{3}{6}=\dfrac{1}{2}$

Events A and B are <u>independent events</u> as the outcome of one event does not affect the outcome of the other event.

For independent events A and B:

$\implies \sf P(A \cap B)=P(A)P(B)$

To find P(A and B), substitute the found values of P(A) and P(B):

$\implies \sf P(A \cap B)=\dfrac{1}{2} \times \dfrac{1}{2}=\dfrac{1}{4}$
