he temperature at noon on a winter day was 2 °F. By 6 p.m., the temperature had dropped to −9 °F. Write a subtraction expression

nydimaria [60]

Based on the starting temperature and the new temperature, the relevant expression would be 2 - (-9)

To find the number of degrees the temperature has changed by, use the following equation:

= Starting temperature - Current temperature

Starting temperature = 2°F

Current temperature = -9°F

The equation becomes:

= 2 - (-9)

In conclusion, the expression would be 2 - (-9)

Find the probability of throwing 9 with two dice.

ololo11 [35]

Total number of possible outcomes of throwing two dice = 6×6 = 36
Number of outcomes of getting 9 i.e, (3+6),(4+5),(5+4),(6+3) = 4

$P = \frac{Number \: of \: favourable \: outcomes}{ Total \: number \: of \: possible \: outcomes}$

$P (throwing \: 9) = \frac{4}{36} = \frac{1}{9}$
