A line is a undefined term because

SashulF [63]3 years ago

The best answer I can think of is that a line doesn't have a point where it starts or stops, but instead goes on forever, unlike a ray which has a start or end point but not the other, and a line segment which has a start and stop point. Hope this helps!

Tell whether the ordered pair (- 3, 0) is a solution of the given system. - 2x + 2y >= 4an y >= 2x - 6
alukav5142 [94]

Answer:

The ordered pair is a solution.

Step-by-step explanation:

Plug x = -3 and y = 0 into the 2 inequalities and see if they fit:

-2x + 2y >= 4

-2(-3) + 2(0) = 6   which is > 4 so this one fits.

y>= 2x - 6

0 >= 2*-3) - 6 = -12 which also fits.

An ant looks up to the top of a tree at an angle of elevation of 40 degrees. If the ant is 30 feet away from the base of the tre
hodyreva [135]
Tangent (40) = tree height / 30 feet
tree height  =  tangent (40) * 30 feet
tree height  =  0.8391 * 30
tree height  =  25.173 feet

You flip a coin and then roll a 6-sided number cube (a die).
expeople1 [14]

Answer:

a)  No, it does not matter whether you roll the die or flip the coin first, as these two events are <u>independent</u> of each other, which means they do not affect each other.

b) Yes.

  • Let event 1 be flipping a coin and event 2 be rolling a die.
  • Let event 1 be rolling a die and event 2 be flipping a coin.

The likelihood that any outcome will occur will not change, as the events are independent.

c) see attached

d)   12 outcomes  (H = head, T = tail, numbers represent the value of the die)

H 1           T 1

H 2          T 2

H 3          T 3

H 4          T 4

H 5          T 5

H 6          T 6

e)  

\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}

\implies \sf P(even)=\dfrac{1}{6}+\dfrac{1}{6}+\dfrac{1}{6}=\dfrac{3}{6}=\dfrac{1}{2}

\implies \sf P(head)=\dfrac{1}{2}

\implies \sf P(even)\:and\:P(head)=\dfrac{1}{2} \times \dfrac{1}{2}=\dfrac{1}{4}

3/5n+15=10+2/5n what is n
Nutka1998 [239]

\textsf{Hey there!}

\mathsf{\dfrac{3}{5}n +15=10+\dfrac{2}{5}n}

\mathsf{\bf{SUBTRACT}\ \mathsf{by\ \dfrac{2}{5}n\ from\ both\ of\ your\ sides}}

\mathsf{Like: \dfrac{3}{5}n+15-\dfrac{2}{5}n=\dfrac{2}{5}n+10-\dfrac{2}{5}n}

\mathsf{\bf{CANCEL: \dfrac{3}{5}+\dfrac{2}{5}}}\textsf{out\ because that gives you\ 1}

\textsf{Solve\ the set we have left over}

\mathsf{Our\ new\ equation\ becomes: \dfrac{1}{5}n+15=10}

\mathsf{\bf{SUBTRACT}}\textsf{ by 15 on both of your sides}

\mathsf{\dfrac{1}{5}n+15-15=10-15}

\mathsf{Cancel\ out: 15-15\ because\ that\gives\ you\ 0 }

\mathsf{Keep: 10-15\ because\ it\ helps\ us\ solve\ for\ your\ n }

\mathsf{10-15=-5}

\mathsf{New\ equation: \dfrac{1}{5}n=-5}

\mathsf{\bf{MULTIPLY}\mathsf{\ both\ sides\ by\ 5}}

\mathsf{\dfrac{1}{5}n\times5=5\times-5}

\mathsf{Cancel\ out\ \dfrac{1}{5}\times5 \ because \  it \ gives \ us \ 1}\mathsf{Keep: 5\times -5\ because\ it\gives\ us\ the\ value\ of\ your\ n}

\mathsf{n =5\times-5}\\\mathsf{5\times-5 = -25}

\textsf{Thus, \underline{\bf{n = -25}}}\checkmark

\boxed{\boxed{\mathsf{Thus,\ your\ answer\ is: \boxed{\boxed{\bf{n =-25}}}}}}\checkmark

\textsf{Good luck on your assignment and enjoy your day!}
