Answer:
A. 5
Step-by-step explanation:
The base AB is twice the length of the midsegment CD.
8n +10 = 2(5n)
8n +10 = 10n . . . . . eliminate parentheses
10 = 2n . . . . . . . . . subtract 8n
n = 5 . . . . . . . . . . . divide by 2
You just divided 1/2 (.5) by 10 which is .05. so the answer is 0.05 gallons
Answer:

Step-by-step explanation:
Given:
.
we need to find the correct form for
if the equation is solve using undetermined coefficients.
A first order differential equation
is said to be homogeneous if
for all t.
Consider homogeneous equation 
Let
be the solution .
We get 
Since
,
.
So, we get solution as 
As constant term and
are already in the R.H.S of equation
, we can take
as 
Answer: 0.065
Step-by-step explanation:
Given : Sample size : n= 320
The sample proportion of people who rent their home : 
Significance level : 
Then , Critical value : 
The formula to find the margin of error : -

Hence, the margin of error for the confidence interval for the population proportion with a 98% confidence level =0.065
Answer:
a) Null and alternative hypotheses are:
: mu=183 days
: mu>183 days
b) If the true mean is 190 days, Type II error can be made.
Step-by-step explanation:
Let mu be the mean life of the batteries of the company when it is used in a wireless mouse
Null and alternative hypotheses are:
: mu=183 days
: mu>183 days
Type II error happens if we fail to reject the null hypothesis, when actually the alternative hypothesis is true.
That is if we conclude that mean life of the batteries of the company when it is used in a wireless mouse is at most 183 days, but actually mean life is 190 hours, we make a Type II error.
