I got a hold of me and her back on the number so i and she said she was ok
Answer:

Step-by-step explanation:
<h3>Derivative </h3>

Since, the derivative of e^x is e^x and e^(yx) is ye^(yx)
First divide 350 with 7
350/7 = 50.
Each player gets 50 tokens.
Now there are 11 players.
Multiply 50 with 11
50 x 11 = 550
550 tokens are distributed for 11 players
hope this helps
C. Supplementary
This means their angles add up to 180° which is a straight line
Answer:
(115.2642, 222.7358).
Step-by-step explanation:
Given data:
type A: n_1=60, xbar_1=1827, s_1=168
type B: n_2=180, xbar_2=1658, s_2=225
n_1 = sample size 1, n_2= sample size 2
xbar_1, xbar_2 are mean life of sample 1 and 2 respectively. Similarly, s_1 and s_2 are standard deviation of 1,2.
a=0.05, |Z(0.025)|=1.96 (from the standard normal table)
So 95% CI is
(xbar_1 -xbar_2) ± Z×√[s1^2/n1 + s2^2/n2]
=(1827-1658) ± 1.96×sqrt(168^2/60 + 225^2/180)
= (115.2642, 222.7358).
