Answer:
x = 5 + √3, 5 - √3
which is 6.73 , 3.27 to the nearest hundredth.
Step-by-step explanation:
(x - 5)^2 = 3
Take the square root of both sides:
x - 5 = +/- √3
x = 5 + √3, 5 - √3
Answer:
opportunity cost for him in this trip for mikael = $1500
Step-by-step explanation:
Mikael has saved $4,000 for his trip to Brazil
transportation expenses = $1,000
hotel expenses = $1,500
food expenses = $500
sightseeing and buying souvenirs expenses = $1,000
additional transportation expenses = $ 200
Total Expenses = $ 4200
In case of cancellation of trip
Total loss = $ 1500
This is the opportunity cost for him in this trip
Hence , in order to save the additional expenditure of $200 , Mikael will have to bear a loss of $ 1500.
Answer:
1) Increase the sample size
2) Decrease the confidence level
Step-by-step explanation:
The 95% confidence interval built for a sample size of 1100 adult Americans on how much they worked in previous week is:
42.7 to 44.5
We have to provide 2 recommendations on how to decrease the margin of Error. Margin of error is calculated as:
Here,
is the critical z-value which depends on the confidence level. Higher the confidence level, higher will be the value of critical z and vice versa.
is the population standard deviation, which will be a constant term and n is the sample size. Since n is in the denominator, increasing the value of n will decrease the value of Margin of Error.
Therefore, the 2 recommendations to decrease the Margin of error for the given case are:
- Increase the sample size and make it more than 1100
- Decrease the confidence level and make it lesser than 95%.
Answer:
Part 1) see the procedure
Part 2)
Part 3) The angles are not congruent. The measure of angle PNQ is half the measure of angle POQ
Step-by-step explanation:
Part 1) Describe the relationship between angle POQ and arc PQ
we know that
<u><em>Central angl</em></u>e is the angle that has its vertex in the center of the circumference and the sides are radii of it
we have that
----> by central angle
Part 2) Describe the relationship between angle PNQ and arc PQ
we know that
The <u><em>inscribed angle</em></u> is half that of the arc it comprises.
In this problem, the angle PNQ is an inscribed angle
so
Part 3) Are the angle POQ and PNQ congruent?
The angles are not congruent, because
substitute
therefore
The measure of angle PNQ is half the measure of angle POQ
