plz me? the price of stock a at 9 a. m. was $14.91. since then, the price has been increasing at the rate of $0.06 each hour. at noon the price of stock b was $15.66. it begins to decrease at the rate of $0.11 each hour. if the two rates continue, in how many hours will the prices of the two stocks be the same?

h = 4.41 hours , when they will equalize.

Step-by-step explanation:

Let the hours when they equalize=h,

14. 91 +0.06 h = 15.66 -0.11 h

0.06 h + 0.11 h = 15.66 - 14.91

0.17 h  = 0.75

h =

h = 4.41 hours , when they will equalize.

x=4

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
