Answer:
a). 59.049°C
b). 2.1179 seconds
Step-by-step explanation:
Expression representing the final temperature after decrease in temperature of the metal from 100°C to T°C is,
T =
where x = duration of cooling
a). Temperature when x = 5 seconds
T = 100(0.9)⁵
= 59.049
≈ 59.049°C
b). If the temperature of the metal decreases from 100°C to 80°C
Which means for T = 80°C we have to calculate the duration of cooling 'x' seconds
80 =
0.8 =
By taking log on both the sides
log(0.8) =log[]
-0.09691 = x[log(0.9)]
-0.09691 = -0.045757x
x =
x = 2.1179
x ≈ 2.1179 seconds

I believe the answer is 4/6 or 2/3 because 1/2=3/6 and 4/6 is in the middle of 3/6 and 5/6
Answer:
5: 0 successes
6: 5 successes
7: 8 successes
8: 6 successes
9: 6 successes
10: 1 success
We need to use her results to estimate the probability that she succeeds at fewer than 7 free-throws in a sample of 10 free-throws.
First, find out how many successes were less than 7 (out of 25), which is 5.
now, we divide 5 by 25 (5/25, formula being number/total attempts) and simplify into a decimal, which comes out to 0.2
