Answer:
there are 45 people in the group
2/3xA=30
2A=30x3
A=90/2
A=45
Answer:
Step-by-step explanation:
x 1 = π , x 2 = 3 π/ 2
y 1 = - 1, y 2 = 2
The Rate of change = ( y 2 - y 1) / ( x 2 - x 1 )=
= [2 -( -1 )] : ( 3 π /2 - π ) = 3 : π/2 = 6 / π <em>≈ 1.91 </em>

Answer: C.-1.5
Step-by-step explanation:
Given: The burning time of a very large candle is normally distributed with mean of 2500 hours and standard deviation of 20 hours.
Let X be a random variable that represent the burning time of a very large candle.
Formula:
For X = 2470
So, the z-score they corresponds to a lifespan of 2470 hours. =-1.5
Hence, the correct option is C.-1.5.
Answer:
slope = -
Step-by-step explanation:
given f(4) = 6 and f(- 2) = 8 , then 2 points on the line are
(4, 6 ) and (- 2, 8 )
calculate slope m using the slope formula
m =
with (x₁, y₁ ) = (4, 6 ) and (x₂, y₂ ) = (- 2, 8 )
m = = = -
