Answer:
-11
Step-by-step explanation:
P(the students she selects are both boys)=7/12×5/10=35/120=7/24
-6-7=-13 because you take -2 and 3 you multiply equals-6 than add -7 and it well give you your answer
Answer:
Congruent and similar
Step-by-step explanation:
because you did not change anything about the shape that shape is still the same size and shape just in a different spot
consider X-axis along the east-west direction and north-south direction along Y-axis
A = magnitude of distance traveled by hiker in north-east direction = 30 kilometer
θ = angle of direction of displacement of the hiker relative to x-axis or east direction = 45 degree counterclockwise
A' = component of distance traveled by the hiker along the east direction.
Since the angle is given with the x-axis, the Sin provides the component in Y-direction. hence
Using the equation
A' = A Sinθ
Inserting the values
A' = (30) Sin45
A' = 21.2 km
