Answer:

{x}^{ - 2}  =  \frac{1}{ {x}^{2} }  \:  \: –> {7}^{ - 2}  =  \frac{1}{ {7}^{2} }  =  \frac{ 1}{49}  \\  \\  {x}^{ - 1}  =  \frac{1}{ {x}^{1} }   \: –>  {7}^{ - 1}  =  \frac{1}{ {7}^{1} } =  \frac{1}{7}  \\  \\  {x}^{0} –> {7}^{0}   = 1 \\  \\  {x}^{1}  –> {7}^{1}  = 7 \\  \\  {x}^{2}  –> {7}^{2}  = 49

What is the change from -9 to -1?.
jarptica [38.1K]

Answer:

Positive 8

Step-by-step explanation:

Since they're both negative numbers and it went from -9 to -1, you had to have added a positive number to get a lesser negative number. To put it simply, if you were to subtract 8 from 9, you'd get 1.

denis-greek [22]

Answer:

1/25 ; 3/20 ; 3/50

Step-by-step explanation:

Total number of stickers :

(10 + 15 + 25) = 50 stickers

Probability = required outcome / Total possible outcomes

a. Selecting blue and blue stickers

P(First blue) = 10/50 = 1/5

P(second blue) = 10/50 = 1/5

1/5 * 1/5 = 1 / 25

b. Selecting one red sticker and then one orange sticker

P(First red) = 15/50 = 3/10

P(second orange) = 25/50 = 1/2

3/10 * 1/2 = 3 /20

Selecting one red sticker and then one blue sticker

P(First red) = 15/50 = 3/10

P(second blue) = 10/50 = 1/5

3/10 * 1/5 = 3 / 50
