Answer:The graph of a proportional relationship is a straight line that passes through the origin. Proportional quantities can be described by the equation y = kx, where k is a constant ratio. You can tell that the relationship is directly proportional by looking at the graph.

Answer:
The number of heads observed is 121.14 heads
Step-by-step explanation:
The formula for the z-score of a proportion is given as follows;
Where:
= Sample proportion
p = Population success proportion = 0.5
q = 1 - p = 1 - 0.5 = 0.5
n = Number in of observation = 200
z = 2.99
Hence, we have;
Therefore;
= 0.6057
∴ The number of heads observed = 200 × 0.6057 = 121.14 heads.
So @mathmate deleted my comment because "I wasn't explaining my answer" well I did
I clearly stated that you have to make educated guess and I showed how I GOT my answer
so i guess here is my "proper" answer
There is no specific formula for this, so you can make an educated guess
for example:
13*5 = 65 (this isn't right because we need a minimum of 114)
so we continue the guessing
I then next tried
13*9
I got 117,
117 is more than 113
making 9 the minimum amount of rows for the hotel parking lot
there ya go @mathmate is that clear enough?
Answer:
Step-by-step explanation:
have the triangles written in the same order to se the corresponding angles
C A . T
⇵ . ⇵ . ⇵
D O . G
∠D ≅∠C
∠O ≅∠A
GD ≅TC
10.
you have an isosceles triangle with vertex angle 48 so the base angle is
(180-48)/2 = 66
32+ x = 66 because is an exterior angle
x= 66-32 = 34
