Answer:Rhombus
Step-by-step explanation:
Answer: k= One- seventh of m.
Step-by-step explanation:
Given equation : 8k + 2m=3m +k ,where k and m are variables
To solve for k, Subtract 2m from both sides,we get
⇒8k+2m-2m=3m-2m+k
Simplify
⇒ 8k=m+k
Subtract k from both sides, we get
⇒ 8k-k=m+k-k
Simplify
⇒ 7k=m
Divide 7 from both the sides, we get
⇒ k=1/7m
⇒ k=one-seventh of m...........>here is the answer.

Answer:
a)
b) 
c) Since the p value is higher than the significance level provided we have enogh evidence to FAIL to reject the null hypothesis and we can't conclude that the true means are different at 5% of significance
Step-by-step explanation:
Information given
represent the mean for 1
represent the mean for 2
represent the population standard deviation for 1
represent the population standard deviation for 2
sample size for the group 1
sample size for the group 2
z would represent the statistic
Hypothesis to test
We want to check if the two means for this case are equal or not, the system of hypothesis would be:
H0:
H1:
The statistic would be given by:
(1)
Part a
Replacing we got:

Part b
The p value would be given by this probability:

Part c
Since the p value is higher than the significance level provided we have enogh evidence to FAIL to reject the null hypothesis and we can't conclude that the true means are different at 5% of significance
