Answer:
L' = (0, 1 )
Step-by-step explanation:
The translation rule
(x, y ) → (x - 2, y - 1 )
Means subtract 2 from the x- coordinate and subtract 1 from the y- coordinate.
L (2, 2 ) → L' (2 - 2, 2 - 1 ) → L' (0, 1 )
Here is part of a timetable for the Paris to Montpellier express train service.
The average speed of the 20 07 train from Paris is 224 km/h. Work out the distance this train travels from Paris to Montpelli
Answer:
772.8 km
Step-by-step explanation:
Speed is the rate of change of distance. Speed is the ratio of distance travelled to time taken. Average speed is the ratio of the total distance travelled to the total time taken, it is given by:
Average speed = Total distance / total time
The 20 07 train leaves Paris at 20:07 and reaches Montpellier at 23:34. This means that the total time taken is 3 hours 27 minutes, that is 3.45 hours.
Given that average speed is 224 km/h, hence:
Average speed = total distance / total time
224 km/h = total distance / 3.45 h
total distance = 224 * 3.45 = 772.8 km

How do I find the Q1 and Q3?
0,0,1,2,2,3,4,4,4,4,5,6,6,7,7
Answer:
Q1 = 2
Q3 = 6
Step-by-step explanation:
Mathematically, we have
Q1 = (n + 1)/4 th term
where n is the number of terms
By the count, we have n as 15
Q1 = (15 + 1)/4
Q1 = 4th term
Looking at the arrangement, the 4th term is 2
For Q3
Q3 = 3(n + 1)/4 th term
n = 15
Q3 = 3 * 4 = 12th term
The 12th term is 6
So that is the 3rd quartile

Answer:
half of 45.7 is 22.85
22.85^2 = 522.1225
522.1225 x pi
Meaning
522.1225π, A
Answer:
[tex]522.12\pi[/tex] inches²
Step-by-step explanation:
The formula for finding the area of a circle is:
[tex]A=\pi r^2[/tex]
If you put 45.7/2 (because you have the diameter and NOT the radius) instead of r you get:
[tex]A=22.85^2\pi[/tex]
Now you calculate:
[tex]A=522.12\pi \\[/tex] inches²

Answer:
x = 7
Step-by-step explanation:
Exterior angle thm:

Answer:
12
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 9^2 = 15^2
a^2 +81 =225
Subtract 81 from each side
a^2 = 225-81
a^2 = 144
Take the square root of each side
sqrt(a^2) = sqrt(144)
a=12
Answer:
a = 12 meters
Step-by-step explanation:
Use pythagorean theorem to identify the missing leg
pythagorean theorem = [tex]a^2+b^2=c^2[/tex]
In this case, we are looking for a so...
[tex]a^2+b^2=c^2[/tex]
[tex]a^2+9^2=15^2[/tex]
[tex]a^2+81=225[/tex]
[tex]a^2=225-81[/tex]
[tex]a^2=144[/tex]
It doesn't make sense for a to be equal to 144 so we must square root 144
144 = [tex]12^{2}[/tex] meters
Final Answer: 12 meters

A company has a policy of retiring company cars; this policy looks at number of miles driven, purpose of trips, style of car and other features. The distribution of the number of months in service for the fleet of cars is bell-shaped and has a mean of 41 months and a standard deviation of 5 months. Using the empirical rule (as presented in class), what is the approximate percentage of cars that remain in service between 46 and 51 months
Answer:
15.85%
Step-by-step explanation:
Empirical rule states that for a normal distribution, 68% of the data falls within one standard deviation, 95% falls within two standard deviation and 99.7% falls within three standard deviation.
Given mean (μ) = 41 months, standard deviation (σ) = 5 months
One standard deviation = μ ± σ = 41 ± 5 = (36, 46)
Therefore 68% falls within 36 months and 41 months
Two standard deviation = μ ± 2σ = 41 ± 2(5) = (31,51)
Therefore 95% falls within 31 months and 51 months
Three standard deviation = μ ± 3σ = 41 ± 3(5) = (26, 56)
Therefore 99.7% falls within 26 months and 56 months
The percentage of cars that remain in service between 46 and 51 months = 32%/2 - 0.3%/2 = 16% - 0.15% = 15.85%

Tulsa has 4 times as many mangoes as Julie. Tulsa bought 6 more mangoes. She now has 5 time as many mangoes as Julie . How many many mangoes Tulsa had at first
Answer:
24
Step-by-step explanation:
Let the number of mangoes owned by Tulsa be T and that by Julie be J
If Tulsa has 4 times as many mangoes as Julie then
T = 4J
Tulsa bought 6 more mangoes. She now has 5 time as many mangoes as Julie
T + 6 = 5J
Solve both equations simultaneously by substitution
4J + 6 = 5J
Collect like terms
6 = 5J- 4J
J = 6
Since
T = 4J
T = 4 * 6
= 24
Hence Tulsa had 24 mangoes at first

Step-by-step explanation:
Mohammed pays $569.80 for a mountain bike in a sale, the original price had been reduced by 26%, calculate the original price of the mountain bike
Answer:
$770
Step-by-step explanation:
26% off means the Mohammed paid 74% of the original price.
0.74x=569.80
x=569.8/0.74
x=770
proof:
770*0.26=200.2
770-200.2=569.8
Can someone explain to me how the Pythagorean theorem works??
Answer:
By the Pythagorean theorem, it follows that the hypotenuse of this triangle has length c = √a2 + b2, the same as the hypotenuse of the first triangle. Since both triangles' sides are the same lengths a, b and c, the triangles are congruent and must have the same angles. ... If a2 + b2 = c2, then the triangle is right.
Step-by-step explanation:
