Sin B = opp/hyp
sin B = 3/5
Answer:
m = 4
Step-by-step explanation:
In order for this equation to be true, the angles must be complementary.
So, 18m- 12 + 7m + 2 = 90
25m - 10 = 90
25m = 100
m = 4
Answer:
And we can find this probability using the normal standard distribution, excel or a calculator and we got:
And if we convert this into percent we got 84.13% rounded to the nearest percent would be:
84%
Step-by-step explanation:
Let X the random variable that represent the circumferences of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard distribution, excel or a calculator and we got:
And if we convert this into percent we got 84.13% rounded to the nearest percent would be:
84%
Since there are like terms, you can combine them
5a-2a = 3a
So, then you get
3a+9
Then you can factor to get a GCF of 3
3(a+3)
