4. Sketch a graph that has the following characteristics. (8 points: 2 points for each characteristic) a. Crosses the y-axis at (0, 4) b. Increases in the interval –12 ≤ x ≤ –2 c. Constant in the interval –2 ≤ x ≤ 2 d. Decreases in the interval 2 ≤ x ≤ 12 Please Help

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

step-by-step explanation:

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

the answer is b.
