What is the probability that a randomly selected student
is a junior who takes the bus?
?
P(Junior' n Take the bus)
Answers
Answer:
The answer is 1/5
Step-by-step explanation:
Trust me.
The probability that a randomly selected student is a junior who takes the bus is [tex]\frac{1}{5}[/tex] .
What is probability?Probability or chance is how likely something is to happen. If something has a low probability, it is unlikely to happen. If something has a high probability, it is likely to happen.
[tex]probability=\frac{number\ of\ favourable\ cases }{total\ number\ of cases}[/tex]
Given,
Total number of students = 100
Number of students who are juniors and take bus = 20
[tex]probability=\frac{number\ of\ favourable\ cases }{total\ number\ of cases}[/tex]
Probability of junior students who take bus = [tex]\frac{20}{100}[/tex]
Probability of junior students who take bus = [tex]\frac{1}{5}[/tex]
Hence, The probability that a randomly selected student is a junior who takes the bus is [tex]\frac{1}{5}[/tex] .

Answer:
R = 90
Step-by-step explanation:
Triangles will always equal 180 degrees. If you add 61 + 29 = 90. If two of the three angles already equal 90 degrees, then you would subtract 180 - 90. Therefore, the remaining angle would have to be 90 degrees.

The two lines represented by the equations below are graphed on a coordinate plane. Which statement best describes
the two lines?
2x + y = 12
y-2 = 3(x - 2)
1) parallel
2) perpendicular
3) the same line
4) neither parallel nor perpendicular
Answers
Answer:
4
Step-by-step explanation:
2x+y=12
y=-2x+12
y-2=3(x-2)
If it’s parallel to each other: the slope has to be the same.
If is perpendicular to each other: the slope should be the reciprocal to each other.
The first equation has a slope of -2
The second has a slope of 3
Neither the condition meet. So the answer is 4

prove that 5root7 is i
rrational
Answers
Answer:
See Explanation
Step-by-step explanation:
Let us assume that [tex] 5\sqrt 7[/tex] is a rational.
Therefore, it can be expressed in the form of [tex] \frac{p}{q}[/tex], where p and q are integers.
[tex] \implies 5\sqrt 7=\frac{p}{q}[/tex]
[tex] \implies \sqrt 7=\frac{p}{5q}[/tex]
[tex] \because [/tex] p and q are integers.
[tex] \therefore \frac{p}{5q}[/tex] is a rational number.
[tex] \implies \sqrt 7[/tex] is rational ([tex] \because [/tex] quotient of a rational number is rational)
But, it contradicts the fact that [tex]\sqrt 7[/tex]is irrational.
So, [tex]5\sqrt 7[/tex] is also irrational, because the product of rational and irrational is irrational.
This contradiction is arising out because of our wrong assumption that [tex] 5\sqrt 7[/tex] is rational.
Hence, [tex] 5\sqrt 7[/tex] is irrational.

A system of equations is shown.
y = 2x – 7
y = -x + 5
What is the solution to the system of equations?
Answers
Answer:
x = 4
Step-by-step explanation:
Eliminate y by setting the first equation equal to the second:
2x - 7 = -x + 5
Combining like terms, we get:
3x = 12, so that x must be 4.

Becky and Keith run for exactly 20 minutes on a treadmill keith's treadmill said he had run 10,000 ft Becky's treadmill had said she had run 2 miles who ran farther and how much farther?
Answers
Answer:
Becky ran farther and farther by 560 ft.
Step-by-step explanation:
1 mile = 5280 ft
Becky: 2 * 5280 = 10560 ft
Keith: 10000 ft
10560 ft > 10000 ft, so Becky ran more distance than Keith.
10560 - 10000 = 560 ft, so Becky ran 560 ft more than Keith.

Answers
Answer:
7,8
Step-by-step explanation:
Distance Formula:
The distance between two points is the length of the path connecting them. The shortest path distance is a straight line. In a 2 dimensional plane, the distance between points (X1, Y1) and (X2, Y2) is given by the Pythagorean theorem:
d=(x2−x1)2+(y2−y1)2−−−−−−−−−−−−−−−−−−√
Calculate Distance
To calculate the distance between 2 points, (X1, Y1) and (X2, Y2), for example, (5, 6) and (-7,11), we plug our values into the distance formula:
d=(−7−5)2+(11−6)2−−−−−−−−−−−−−−−−−√
combining terms inside parentheses we get:
d=(−12)2+(5)2−−−−−−−−−−−√
squaring both terms we get,
d=144+25−−−−−−−√
adding the 2 results,
d=169−−−√
finally,
d=13
