Answer: Age:25
Step-by-step explanation:
Answer: 0.023
Step-by-step explanation:
Given that:
Number of green balls = 9
Number of white balls = 8
Total number of balls = 9 + 8 = 17
Drawing with replacement :
Probability of white :
First draw = 8/17
2nd draw = 8/17
3rd draw =. 8/17
4th draw = 8/17
5th draw = 8/17
P(all 5 are white) = 8/17 * 8/17 * 8/17 * 8/17 * 8/17 = 32768/1419857
= 0.0230783
= 0.023
Answer:
B and C only show direct proportion
It would take 1.045 minutes for both substances to be at the same temperature.
Substance A started at a temperature of 96.2 and is rising at 1.4 every minute. Assuming minutes were denoted as x, the relevant expression would be:
<em>= Starting temperature + (Rate temperature is rising x number of minutes)</em>
= 96.2 + 1.4x
Substance B is reducing in temperature:
= 98.5 - 0.8x
<u>Equate both expressions:</u>
96.2 + 1.4x = 98.5 - 0.8x
1.4x + 0.8x = 98.5 - 96.2
2.2x = 2.3
x = 2.3 / 2.2
= 1.045 minutes
It would therefore take 1.045 minutes for both substances to be at the same temperature.
