Answer:

B. f(x) = 5x - 7

Step-by-step explanation:

✔️Using the table of values given, find the slope (m) and y-intercept (b) of the line of the graph that represents the table, then write the function in slope-intercept form.

✔️Slope (m) using (0, -7) and (2, 3):

Slope (m) = ∆y/∆x

Slope (m) = (3 -(-7))/(2 - 0)

Slope (m) = 10/2

Slope (m) = 5

✔️ y-intercept (b):

b = -7, because where x = 0, y = -7, which is the point where the y-axis is intercepted by the line of the graph.

✔️Write the linear function in slope-intercept form by substituting m = 5 and b = -7 into f(x) = mx + b

Thus:

f(x) = 5x + (-7)

f(x) = 5x - 7

Therefore, the linear function that has a graph that includes all the points in the table would be f(x) = 5x - 7.

in a survey, 8 out of 32 students preferred vanilla ice cream if 252 students are surveyed how many should theoretically prefer
nata0808 [166]

Answer:

63 people

Step-by-step explanation:

Given parameters:

Number of students survey = 32

Number of those that liked ice-cream = 8

Total population size  = 252

Unknown:

How many people in the population should prefer ice cream  = ?

Solution:

  From the survey;

    8 out of 32 students prefer ice cream;

     8 : 32

     1: 4

This shows that 1 out of 4 students will prefer ice cream

NOw to the total population;

  If out of 4 students, 1 prefers ice-cream;

     Out of 252 students   y will prefer ice-cream

     Number of students that prefers ice-cream = \frac{252}{4} = 63people
