Answer:
(b) It means that the results that Tessa obtained are too unusual to be explained by chance alone
Step-by-step explanation:
The test for statistical significance is a comparison of the result to the probability that it occurred by chance. The probability of a chance occurrence is usually set at 1% or 5%. The lower the percentage, the less likely a chance occurrence is, and the more difficult showing statistical significance becomes.
Answer:
121
Step-by-step explanation:
dP/dt is propotional to P^½
dP/dt = k(P^½)
When P=100, dP/dt=+20
20 = k(100^½)
20 = 10k
k = 2
dP/dt = 2(P^½)
Reciprocate both sides:
dt/dP = 1/[2(P^½)]
dt/dP = ½[P^(-½)]
Integrate wrt P.
t = ½ [(P^½) ÷ ½] + c
t = P^½ + c
Using t = 0, P =100.. find c
0 = 100^½ + c
0 = 10 + c
c = -10
t = P^½ - 10
Find P when t=1
1 = P^½ - 10
P^½ = 11
P = 121
Answer:
5 ÷ 5 = 1 - No remainder! 5 is one of the factors! The orange divisor above are the prime factors of the number 675. If we put all of it together we have the factors 3 x 3 x 3 x 5 x 5 = 675.

Answer:
96
Step-by-step explanation:
--> (2^6 * 81 * 48)/2^5 * 3^4
--> (64 * 3^4 * 48 )/ (32 * 3^4) .........3^4 cancels out
--> 3072/32
--> 96
