The distance Train A travels is represented by d = 80t, where d is the distance in kilometers
and t is the time in hours. The distance Train B travels at various times is shown in the
table. What is the rate of each train? Which train is going faster?
Time (hours) Distance (km)
2
190
4
380
5
475
The rate of Train A is 160|
km per hour.
The rate of Train Bis
km per hour.
Train (select)
is going faster.
Answer:
Train B is going faster than Train A
Step-by-step explanation:
The distance travelled by Train A, d = 80t
The distance travelled by Train B is given as follows;
Time (hours) [tex]{}[/tex] Distance (km)
2 [tex]{}[/tex] 190
4 [tex]{}[/tex] 380
5 [tex]{}[/tex] 475
Therefore, we have that the rate of change of Train B is given as follows;
(475 - 380)/(5 - 4) = 95 km/h
(475 - 190)/(5 - 2) = 95 km/h
The rate of change of Train B = 95 km/h
While the distance covered by Train A per 1 hour, t = 1 is given as follows
Distance covered in 1 hour for Train A, d = 80 × 1 = 80 kilometers
The rate of train A = Distance covered/(Time in which the distance was covered)
The rate of train of change A = 80 km/(1 hour) = 80 km/hour
The rate of train of change A = 80 km/h
Therefore, Train B is going faster than Train A.
find the slope between two points with fractions
Answer:
m = 2/5
Step-by-step explanation:
If you look carefully you see that each new y value is obtained by adding 2/5 to the previous one. That 4/5 came from adding 2/5 to 2/5.
If we move from x = 0 to x = 1, y increases from 6/5 to 8/5.
Thus: the "run" is 1; the "rise" is 2/5.
Thus, the slope is m = rise / run = 2/5 divided by 1, or just m = 2/5

A sample denotes a smaller, controllable form of a larger cluster. It is a subset comprising of the characteristics of a bigger population. Samples are used in statistical experiments when the population under consideration is too large for the test to include all the members.
The sample size in this case = 10 + 23 + 28 + 14 = 75
Thus, the size of your sample is 75.

What is the isosceles triangle?
A summation, also abbreviated as a sum, is the consequence of adding two or more numbers or quantities. Usually are always an equivalent number of terms in a summation.
There could be only two terms, and there could be one hundred, thousand. There seem to be summations with an infinite number of representatives.
On another hand, an isosceles triangle is a triangle in which any two sides or angles will be the same.
Hence given that the triangle has
Angle first = 70°
Angle second = 70° since there are two angles same so there will also be two sides equal so it will be an isosceles triangle.

a) Find x so that P(Z ≤ x) = 68%
b) Find the data value x at the 47th percentile
c) Find the data value x at the 50th percentile
Please give answers for all three questions. Thank you!
Answer:
a.) 0.468
b.) -0.075
c.) 0
Step-by-step explanation:
Given the distribution :
Z~N(μ = 0,σ = 1)
Distribution = normal
Mean (μ) = 0
Standard deviation (σ) = 1
a) Find x so that P(Z ≤ x) = 68%
Using the z probability calculator : Zscore corresponding to 68% = 0.68 = 0.468
Usingbthe relation :
Zscore = (x - m) / σ
0.468 = (x - 0) / 1
0.468 = x - 0
x = 0.468
b) Find the data value x at the 47th percentile
47th percentile = Zscore of - 0.075
Zscore = (x - m) / σ
-0.075 = (x - 0) / 1
-0.075 = x - 0
x = -0.075
c) Find the data value x at the 50th percentile
50th percentile = Zscore of 0.0
Zscore = (x - m) / σ
0.0 = (x - 0) / 1
0.0 = x - 0
x = 0
