10/3 goes where 3 and 1/3 is.
This is because 10/3 as a mixed number is 3 and 1/3.
17/3 is where 5 and 2/3 is. Do the same thing as before.
Hope this helps!
We know that
the addition rule states that
P(A or B) = P(A) + P(B) − P(A and B)
in this problem
P(A)=0.72
P(B)=0.84
P(A and B)=0.64
so
P(A or B) = P(A) + P(B) − P(A and B)-----> 0.72+0.84-0.64
P(A or B) = 0.92
the answer is
0.92 (92%)
Cos θ = adjacent / hypothenus = 5/13
opposite = sqrt(hypothenus^2 - adjacent^2) = sqrt(13^2 - 5^2) = sqrt(169 - 25) = sqrt(144) = 12
sec θ = 1/cos θ = 1/(adjacent / hypothenus) = hypothenus / adjacent = 13/5
cot θ = 1/tan θ = 1/(opposite/adjacent) = adjacent / opposite = 5/12
sec θ = 13/5
cot θ = 5/12
Change mixed fraction to improper fraction and also the second fraction has to be reciprocal
Ex- 3/8= 8/3
So now the problem is
13/8*8/3= 13/3 (because you cross divide) Now, turn into fraction
Divide
13 divided by 3= 4 1/3
So your final answer is 4 1/3
I think you have the right answer she paid $55 dollars for each chair
