Answer: t = 10
Step-by-step explanation:m
Given that; n₁ = 10, n₂ = 10
ж₁ = 50, ж₂ = 30
Sˣ₁ = 20, Sˣ₂ = 20
Now using TEST STATISTICS
t = (ж₁ - ж₂) / √ ( Sˣ₁/n₁ + Sˣ₂/n₂ )
so we substitute our figures
t = ( 50 - 30 ) / √ ( 20/10 + 20/10 )
t = 20 / √4
t = 10
Step-by-step explanation:
the first derivative by using
f’(x)=xn = nx^(n−1)
f(g(x)) = f’(g(x))g’(x)
So f’(x)=2(x⅔ -1)*(2/3 x^(-1/3))=
Second derivative by using:
h’(x)=f(x)*g(x)=f(x) g’(x) + f’(x) g(x)
f’’(x)=
Answer:
24
Step-by-step explanation:
the reason behind that is the sequence is 4 Petunias at $1.50 and her money is left $3 at the end so if we want to finish her money to buy maximum Petunias then we will have 3 divided by 1.50 which would be equal to 2.
We can deduce that there are 4 petunias per $1.50 so the answer 2 would be multiplied by 4 and the answer 8 would be added to 16
which gives 24
