Answer:
An example of such number is 1,645,378 ( The value of 6 here is 600,000)
Step-by-step explanation:
Here, we want to compare digits in whole
numbers.
The value of 6 in 165,438 = 60,000
Now, we want a number that is 10 times the value of 6 here
10 times the value of 6 here will be 10 * 60,000 = 600,000
So we want a number which has the value of 6 in it as 600,000
The number in this case as an example can be ;
1,645,378
Answer:
21
Step-by-step explanation:
cross multiply
42 x 24 = 48x
1008 = 48x
x = 21
Answer:
32/12
Step-by-step explanation:
To calculate the tangent you need to divide the opposite side by the adjacent side: 70/24=35/12
Answer:
<em>Find the probability of success in a single trial and then think about the nature of the problem (when do we stop). </em>
Step-by-step explanation:
Observe that in the single trial, we have (8 4) possibilities of choosing our set of balls. If we have chosen two white balls and two black balls, the probability of doing that is simply
p=(4 2)*(4 2)/(8 4)
This is well know Hyper geometric distribution. Now, define random variable X that marks the number of trials that have been needed to obtain the right combination (two white and two black balls). From the nature of the problem, observe that X has Geometric distribution with parameter p that has been calculated above. Hence
P(X = n) = (1— p)^n-1 *( p )
