Based on the starting temperature and the new temperature, the relevant expression would be<u> 2 - (-9) </u>
To find the number of degrees the temperature has changed by, use the following equation:
<em>= Starting temperature - Current temperature </em>
Starting temperature = 2°F
Current temperature = -9°F
The equation becomes:
<em>= 2 - (-9)</em>
In conclusion, the expression would be 2 - (-9)

Answer:
Probability of picking Red ball is 27.5%
Step-by-step explanation:
Given:
Total Number of balls = 200
Number of White balls = 100
Number of Red balls = 55
Number of Black balls = 45
We need to find the probability of the ball picked to be red.
Solution:
Now we know that;
Probability is equal to number of Possible Outcomes divide by total number of Outcomes multiplied by 100.
framing in equation form we get;



Hence Probability of picking Red ball is 27.5%.

Answer:
x= −5±√−7 / −2 --> (No Real Solution)
Step-by-step explanation:
−x^2+5x−6−2=2−2
−x^2+5x−8=0
x= −(5)±√(5)2−4(−1)(−8) / 2(−1)
x= −5±√−7 / −2
