Answer:

No

Step-by-step explanation:

For x and y to have a proportional relationship, then

the ratio of k = \frac{y}{x} must be equal for all points

(2, 5) → k = \frac{5}{2} = 2.5

(3, 7.5) → k = \frac{7.5}{3} = 2.5

(5, 12.5) → k = \frac{12.5}{5} = 2.5

(18, 8) → k = \frac{18}{8} = 2.25 ≠ 2.5

k is not equal for all values , hence no proportional relationship exists

A hi school is conducting a survey to see how many students have part time jobs. Would this sample be biased or unbiased?
nalin [4]
It would be biased because one would assume that students can get to school by means other than those that put them 8n the parking lor. (Parking lot = car drivers who would be the only students sampled.). Others may ride to school by either parent or school bus who could drop them off somewhere else or possibly walk to school. The freshmen/sophomores would be excluded generally as they would be too young to drive altogether

Can anybody help me with this plzzz‼️<br> (If answer is correct i will cashapp you $6)
Ganezh [65]

Step-by-step explanation:

h(x) = 3. g(x) + 5

x= -1 h(x) = 3×8 + 5= 29

x= 0h(x) = 3×5 + 5= 20

x= 2 h(x) = 3×1 + 5= 8

x= 5 h(x) = 3×-5 + 5= -10

An equation that passes through (0, -2/3) and (-3, -2/3)
9966 [12]

Answer:

y = 0x - 2/3

Step-by-step explanation:

We are asked to find the equation of the line

Step1: find the slope

( 0 , -2/3) ( 3 , -2/3)

m = (y_2 - y_1 )/ (x_2 - x_1)

x_1 = 0

y_1 = -2/3

x_2 = 3

y_2 = -2/3

Insert the values into the equation

m =( -2/3 - (-2/3) / (3 - 0)

= -2/3 + 2/3 / 3

= 0 / 3

m = 0

Step 2: sub m into the equation

y = mx + c

y = 0x + c

Step 3: sub any of the two points given into the eqn

y = 0x + c

Let's pick ( 3 , -2/3)

x = 3

y = -2/3

-2/3 = 0(3) + c

-2/3 = 0 + c

c = -2/3

Step4: sub c into the equation

y = mx + c

y = 0x + c

y = 0x - 2/3

Therefore, the equation of the line is

y = 0x - 2/3
