a school librarian ordered new books for the library. 1/3 are science 2/5 are biography and the rest of the books are fiction. What fraction of the books ordered are fiction?

4/15

Step-by-step explanation:

1/3 + 2/5

Use common denominator of 15

5/15 + 6/15 = 11/15

What fraction of the books ordered are fiction?

1 - 11/15

Use common denominator of 15

15/15 - 11/15 = 4/15

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
