Two event are dependent if the probability of occurrence of one event impacts the probability of occurrence of the other event.

Option A lists independent events, as the occurrence of one event is not affecting the occurrence of other event.

Option B lists dependent event. Because when one card is picked and not replaced back in the deck, this will reduce the number of cards by 1 and therefore this will affect the probability of occurrence of second event.

In options C the card is replaced and therefore the total number of cards does not change and the probability of occurrence of second event is not changed.

In option D, the two events involved are not affecting each other and so they are also independent.

Therefore, option B is the correct answer

Which of the following could be the lengths of the sides of a 30°-60°-90° triangle?

Inga [223]

According to Pythagoras theorem

a^2+b^2=c^2

similarly ,

3^2+ 4^2= 5^2

9+16=25
25=25

LHS=RHS
so angle of triangle is 30 , 60 and 90

answer is 3,4,5

first we'll have to do it in order which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)

Step-by-step explanation:

(22÷2-2.5)+(4-6+6)

(11-2.5)+(4-6+6)

(8.5)+(4)

John deposited $800 dollars in a bank that pays 5% interest per year. Find how many years it would take for his money to grow $9

gregori [183]

Answer:

It will take 3 years and 9 months or simply 3.75 years

Step-by-step explanation:

For his money to grow to $950, this means he had earned an interest of the value $950 - $800 = $150

Now, to calculate the number of years it took to earn this interest, we make use of the simple interest formula

mathematically,

I = PRT/100

since we are looking for T, we can rewrite the equation to be?;

100I = PRT

T = 100I/PR

where I is the interest which is $150

R is the rate charged on the deposit and that is 5% per annum

P is the amount deposited initially which is 800

while I is the interest which is $150

Now plugging these values;

T = (100 * 150)/(5 * 800)

T = 15000/4,000 = 3.75 years or simply 3 + (0.75 * 12) = 3 years 9 months
