You need to use the binomial probability formula:
where:
n = total number of events = 10
k = number of events we are testing = 6
p = probability of event happening = 0.5
= 210×0.015625×0.0625
= 0.205078
Hence, the probability of getting 6 boys out of 10 births is
p = 0.205.
The answer is 3.
the equation: 4x+6+3=17
4x+9=17
subtract 9 from both sides
4x=12
x=3
check by inserting 3 as x into the original equation
4*3+6+3=17
hope this helps!
Your answer would be (4y+1)(y+6)
Answer:
B. 9
Step-by-step explanation:
So when solving a question like this, you may try to find what 3⁴ is and what 3² is and divide, but there is a much easier way to do this. Remember:
This can be used to find without finding what 3⁴ is. This is how we would do it:
And now we get the solution, 9, which is answer choice B.
I hope you find my answer helpful.
Hi there, 23*3=69, you can't go over 69. So, 3 can go into 70 about 23 times, but if you want to me more specific it would be 23.3 times.
