This is why you need to check both ways: sometimes there are fussy technical considerations, usually involving square roots, that force the composition not to work, because the domains and ranges of the two functions aren't compatible.

The authors of a certain paper describe a study to evaluate the effect of mobile phone use by taxi drivers in Greece. Fifty taxi drivers drove in a driving simulator where they were following a lead car. The drivers were asked to carry on a conversation on a mobile phone while driving, and the following distance (the distance between the taxi and the lead car) was recorded. The sample mean following distance was 3.80 meters and the sample standard deviation was 1.19 meters.
Construct a 95% confidence interval (in meters) for μ, the population mean following distance while talking on a mobile phone for the population of taxi drivers. (Round your answers to three decimal places.)
Answers
Answer:
CI = (3.462, 4.138)
Step-by-step explanation:
We are given;
Sample mean; x¯ = 3.8
Sample standard deviation; s = 1.19
Sample size; n = 50
DF = n - 1 = 50 - 1 = 49
Confidence level; CL = 95%
Significance level = (1 - 0.95)/2 = 0.025
Now,from the table attached using DF = 49, significance level = 0.025, one tail and by interpolation, we have; t = 2.01
Now, formula for confidence interval is;
CI = x¯ ± t(s/√n)
CI = 3.8 ± 2.01(1.19/√50)
CI = 3.8 ± 0.338
CI = (3.8 - 0.338, 3.8 + 0.338)
CI = (3.462, 4.138)

7.4 + 12.5 ≥ 19.9
TRUE
12.5 + 19.9 ≥ 7.4
TRUE
7.4 + 19.9 ≥ 12.5

6 - 4x = 6x - 8x + 2
6 - 4x = ___ + 2
6 = ___ + 2
___ = ___
___ = x
Answers
Answer:
6 − 4 x = 6 x − 8 x − 2 Since x
is on the right side of the equation, switch the sides so it is on the left side of the equation.
6 x − 8 x − 2 = 6− 4 x Subtract 8 x from 6 x . − 2 x − 2 = 6 − 4 x
Move all terms containing x
to the left side of the equation.
Tap for fewer steps...
Add 4 x
to both sides of the equation.
− 2 x − 2 + 4 x = 6 Add − 2 x and 4 x . 2 x − 2 = 6
Move all terms not containing
x to the right side of the equation.
Tap for fewer steps...
Add 2
to both sides of the equation.
2 x = 6 + 2 Add 6 and 2 . 2 x = 8
Divide each term by
2 and simplify.

Divide each term in

If one order of fries and five burgers cost twice as much as three orders of fries and two burgers, how many times as much does a burger cost compared to one order of fries? to start the problem is 1f+5b=2 (3f+2b)
Answers
Answer:
A burger cost five times as much as a fries.
Step-by-step explanation:
Let F represent fries
Let b represent burgers
From the question:
An order of fries and five burger can be written as:
f + 5b
Three orders of fries and two burgers can be written as:
3f + 2b
But an order of fries and five burgers cost twice as much as three orders of fries and two burgers. This can be written as:
f + 5b = 2(3f + 2b)
Now, we shall make b the subject of the above equation. This is illustrated below:
f + 5b = 2(3f + 2b)
Clear bracket
f + 5b = 6f + 4b
Collect like terms
5b – 4b = 6f – f
b = 5f
Thus, a burger cost five times as much as a fries.
To buy a car, you borrow $25,000 with a term of three years at an APR of 6.5%. What is your monthly
payment? Show all work
Answers
Answer:
$766.23
Step-by-step explanation:
The amortization formula is appropriate for this. (Better, use a financial calculator or spreadsheet.)
A = P(r/12)/(1 -(1 +r/12)^-(12t))
where P is the amount borrowed (25,000), r is the annual rate (0.065), and t is the number of years (3).
Putting the given numbers into the formula, we have ...
A = $25,000(0.065/12)/(1 -(1 +0.065/12)^(-36))
A = $25,000(.00541667)/(1 -1.00541667^-36)
A = $25,000(0.00541667)/(0.1767322)
A = $766.23
The monthly payment is $766.23.

The sides of the triangle do not satisfy the Pythagorean Theorem.
Step-by-step explanation:
If we are given the three sides to a triangle, and we are asked to find out if it is a right triangle, we will have to see if the sides of the triangle satisfies the Pythagorean Theorem. The Pythagorean Theorem is:
a² + b² = c²
where c is the hypotenuse and a and b are the other two sides.
So we can see from the image that 28 would be the length of the "hypotenuse" and 19 and 20 would be the lengths of the other two sides. Lets see if these values satisfy the Pythagorean Theorem:
19² + 20² = 28²
361 + 400 = 784
761 ≠ 784
So no, the triangle is not a right triangle because the sides does not satisfy the Pythagorean Theorem.

At a Halloween fair, you see a huge Ferris wheel. There are ten seats on the wheel, with two people placed on each seat. Every minute, a seat passes by the exit platform. The Ferris wheel opened for 30 minutes at 11 a.m. and doubled its speed after fifteen minutes. How many people rode the wheel during this time?
Answers
Answer:
i believe 90 would be your answer.
Step-by-step explanation:
There are 10 seats and 2 people on each
2 times 10 = 20
the wheel was open for a total of 45 min
since every minute people are being switched out you have to do 2 times 10 4 times witch gives you 80 and the last 5 min you count 2 for each min and then your final answer will be 90.

Answers
Answer:
the length of MR = 9
Step-by-step explanation:
Looking at the figure, we can tell that segment TR is congruent to segment RA, meaning TR has equal length to RA and the same goes to MR and RH. Since the problem gives us the total length of line TA and line MH, we can say that the length of MR is half of the total length of MH. Therefore, length of MR is 9.
