Answer:
The probability of getting exactly 3 head=0.3125
Step-by-step explanation:
Given that probability of getting head p=0.5
So probability of getting tail q=0.5
Number of coin toss n=6
And number of trial r=3
We know that from Binomial distribution function,the probability given as follows
So now by putting the values
Now by solving this
The probability of getting exactly 3 head=0.3125
To do this you would have to use the Pythagorean Theorem, which is
a^2+b^2=c^2
The longest side would be your c^2, the smallest side is your a^2, and the remaining side is your b^2
The 7 is your a^2, 24 is b^2, and x is c^2
Plug in the numbers into your equation
7^2+24^2=x^2
Then, just solve:
49+576=x^2
625=x^2
To get rid of the ^2 in x^2, you would have to square root both sides to get x by itself
25=x
So x is equal to 25
Hope this helps!
Hey there!
A number that is divisible by both 2 and 9 is 18. This is just 2 multiplied by 9. To make this into a 3-digit number, you can just multiply 18 by itself. This will be 324, which is divisible by 9 and 2.
324 ÷ 2 = 162
324 ÷ 9 = 36
So, a number you could choose is 324.
Hope this helped you out! :-)
Answer:
You need to add more to it than just find the missing fraction because that doesnt tell us anything cause for us it looks like you answered it already
