Answer:
Step-by-step explanation:
In first half,
Let number of 2-point shots=x
Points scored on free throws=9
Point scored in x number of 2-point shots=2x
In second half,
Number of 3-point shots=number of 2-point shots in first half=x
Point scored in x number of 3-point shots=3x
Therefore, the player scored total number of points in the game is given by
Hence, the expression which represents the total number of points scored by player in the game is given by
Given :
p = 0.68
margin of error, E = 0.1
99% confident interval
alpha, α = 1 - 0.99
= 0.01
∴ (z-critical value)
Sample size =
= 144.37
= 145 (rounded off)
Therefore, there are 145 businesses does she need to sample to meet this criteria.
Answer:
<h2> 63° or 173°</h2>Step-by-step explanation:
You didn't specify where the point P is so there are two posibilites:
1.
P₁Z is dividing angle OZQ
then:
m∠P₁ZQ = m∠OZQ - m∠OZP₁ = 125° - 62° = 63°
2.
P₂Z is outside angle OZQ
then
m∠P₂ZQ = 360° - (m∠OZQ + m∠OZP₂) = 360° - (125° + 62°) = 173°
