Answer:  Fraction of twins = \frac{5}{8} Fractions of triplets = \frac{1}{4} Fractions of quadruplets = \frac{1}{8}

Step-by-step explanation:

Since we have given that

Number of set of twins = 5

Number of sets of triplets = 2

Number of sets of quadruplets = 1

Total number of sets is given by

5+2+1=8

Now, we need to find the fraction of those students.

So, Fraction of twins is given by

\frac{5}{8}

Fractions of triplets is given by

\frac{2}{8}=\frac{1}{4}

Fractions of quadruplets is given by

\frac{1}{8}

Which pair of equations below represent parallel lines? and y = 9 and x = 18 y = 4x + 9 and y = 4x – 9 y = 5x + 15 and y = –5x +
Inessa05 [86]

Answer:

The correct option is 2.

Step-by-step explanation:

The slope of two parallel lines are equal.

The slope intercept form of a line is

y=mx+b

Where, m is slope and b is y-intercept.

In option 1, the equation of lines are

y=9

x=18

The first line is a horizontal line and the second line is a vertical line. Therefore they are not parallel line. Option 1 is incorrect.

In option 2, the equation of lines are

y=4x+9

y=4x-9

By using the slope intercept form of a line, the slope of first line is 4 and the slope of second line is 4.

Since the slope of both lines are same, therefore both lines are parallel. Option 2 is correct.

In option 2, the equation of lines are

y=5x+15

y=-5x+15

By using the slope intercept form of a line, the slope of first line is 5 and the slope of second line is -5.

Since the slope of both lines are not same, therefore both lines are not parallel. Option 3 is incorrect.

Help me please i need this urgent
Pavel [41]
In pythagoras's theorem, generally a is the shortest side, b is the second shortest and c is the hypotenuse: a^{2} +  b^{2} = c^{2}. However, there is a problem. The questions aren't actually possible without using sine, cosine, and tangent (which are mathematical ratios if you didn't know). I can help you with this but it will take time explaining.
