3n=27+3
you can do anything as long as you do it to both sides
3n=27+3
add like terms
27+3=30
3n=30
divide both sides by 3
n=10
Answer:
C. 7
49 square rooted would be 7 and the 4 in (x+4) would be negative and not positive like the answer shows.
3+2=5
6+6=6 just carry over the six
it's at its simplest form
DE^2 = 1 + 16 = 17.
<span>EF^2 = 16 + 1 = 17. </span>
<span>DF^2 = 9 + 25 = 34. </span>
<span>Since (DE)^2 + (EF)^2 = (DF)^2,
</span><span> angle E is 90 degrees.
</span><span> DF must be the hypotenuse
</span>see attachment below
Answer:
a) P=0.2
b) P=0.1
Step-by-step explanation:
We have a total of 1,000 employees in the company.
Out of this 1,000 employees, 200 had colds. If this proportion allow us to estimate the probability of next year colds, we have:

If we take only the ones that are involved in excercise programs, we have 50 cases of cold out of 500 employees (half of the total employees).
The probabillity of cold for them is then:
