item 3
andy found three ordered pairs, (0, 250), (5, 575), and (10, 900), for the equation, y = 65x + 250.
when he graphs these, what is the minimum range for the y-axis?
0 to 900
0 to 250
0 to 10
65 to 250

0 to 900

Step-by-step explanation:

The three ordered pairs, (0, 250), (5, 575), and (10, 900) for the equation,

y = 65x + 250

imply that the y-axis should range from 0 to 900. The y-values from the ordered pairs are; 250, 575 and 900

5

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
