Answer:
11.4
Step-by-step explanation:
40% of 38 is 15.2, 38-15.2=22.8. 22.8/2=11.4 (since there's two people)
We are to verify the identity:
cos(α-B)-cos(α+B) = 2 sinα sinβ
Left hand side = cos(α - B)-cos(α + B)
= cosα cosβ + sinα sinB - (cosα cosB - sinα sinβ)
= cosα cosβ + sinα sinB - cosα cosB + sinα sinβ)
= sinα sinβ + sinα sinβ
= 2 sinα sinβ
= Right Hand side
When looking at a graph, discrete data will have all the pints connected so it will look something like the 1st picture that I provided. Something that is discrete can not be broken down into decimals or fractions so we usually say discrete things can be counted.
On the other hand, continuous data is usually things that we associate with measuring. These types of graph will have dots all over them and they can have fractions and decimals in them.
Answer:
The expression is half the value of (10 + 12)
Step-by-step explanation:
We see the top part is 10 + 12
The whole thing is a fraction and 2 is in the denominator
You divide your term by your denominator, and diving by 2 is the same as 1/2 if a term.
The sum of 44+40 is 84 then the greatest common factor would be 4 because when you divide 84 and 4 you get 21 (the GCF is 4)
