The temperature outside is -5 degree f. name the temperature that would make the sum of the two temperatures 0 degree f ?

5 °F

Step-by-step explanation:

Let t represent the temperature of interest in degrees F. You want the value of t to satisfly ...

t + (-5) = 0

Add 5 to both sides of the equation:

t -5 +5 = 0 +5

t = 5

The temperature that would make the sum be 0 °F is 5 °F.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

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
