A random sample of 40 seniors reveals that 10% of those sampled have assigned parking spaces in the high school’s main lot. This is surprising because, according to the main office of the large high school, 45% of seniors have assigned parking spaces in the high school’s main lot. Which of the following statements is true? The population is all seniors and the sample is the 40 seniors who were randomly selected.
The population is the 40 seniors who were randomly selected and the sample is all seniors.
The population is all assigned parking spaces and the sample is the 4 seniors selected who have an assigned spot.
The population is the 4 seniors selected who have an assigned spot and the sample is all assigned parking spaces.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

step-by-step explanation:

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
