Answer:
Step-by-step explanation:
The coefficient of a variable is always the number before the variable, if there is no number before a variable the coefficient is always 1. :)
In this case, the coefficient is 7.
8-8^-1
=8-1/8 <<< 8*8=64 then 64-1=63
=63/8
in decimal(7.875)
Answer:
The correct answer is option C. 3/5= 0.60
Step-by-step explanation:
It is given that,the Venn diagram shows sports played by 10 students.
event A = The student plays basketball.
event B = The student plays soccer
<u>To find P(A|B))</u>
P(A) = 6
P(B) = 5
P(A ∩ B) = 3
We have P(A|B) = P(A ∩ B)/P(B)
= 3/5
= 0.6
Therefore the correct answer is option C. 3/5= 0.60
I think it is -2, if that helps
Answer:
θ = 38°
Step-by-step explanation:
The lower right triangle is congruent to the upper left triangle, so we have θ and 20° being the two acute angles in the triangle. The law of sines tells you ...
sin(θ)/9 = sin(20°)/5
sin(θ) = (9/5)sin(20°)
θ = arcsin(9/5·sin(20°)) ≈ 38°
___
Another solution to the triangle is θ = 180° -38° = 142°. The diagram clearly shows θ as an acute angle, so we take this second solution to be extraneous.
