Answer:
Make it 15 squares every side
Because 1 mm is 2 squares then 7.5mm is 15 squares
Answer:
y = -4x - 1
Step-by-step explanation:
k(x) = -4x - 1
replace k(x) with y
y = -4x - 1
Answer: 5.8%
Step-by-step explanation:
In this situation there is no replacement so we have to mulitply the probablilty of the first,second, and third marble being green. First marble has a 8/19 probablilty of being selected because 19 total marbles in the bag and 8 green marbles. the next marble will have a 7/18 probabililty because now only 18 marble are in the bag and we are assuming we selected a green marble on our first draw. Same thing with the last green marble it would be 6/17 because there would be 17 marbles in the bag and 6 green ones left assuming we got the first 2
so 8/19*7/18*6/17=
56/969=
0.05779
5.77%
5.8%
Recuerda que
• |<em>x</em>| = <em>x</em> si <em>x</em> ≥ 0
• |<em>x</em>| = -<em>x</em> si <em>x</em> < 0
Necesitas considerar dos casos:
• si <em>x</em> - 3 ≥ 0,
|<em>x</em> - 3| < 1 ⇒ <em>x</em> - 3 < 1 ⇒ <em>x</em> < 4
• si <em>x</em> - 3 < 0,
|<em>x</em> - 3| < 1 ⇒ -(<em>x</em> - 3) = 3 - <em>x</em> < 1 ⇒ -<em>x</em> < -2 ⇒ <em>x</em> > 2
Entonces la solución consta de todos los números reales <em>x</em> tales que <em>x</em> > 2 y <em>x</em> < 4, o simplemente 2 < <em>x</em> < 4.
El método para resolver las otras desigualdades es el mismo.
|4<em>x</em> + 1| > 0 ⇒ 4<em>x</em> + 1 > 0 o -(4<em>x</em> + 1) > 0
… ⇒ 4<em>x</em> + 1 > 0 o -4<em>x</em> - 1 > 0
… ⇒ 4<em>x</em> > -1 o -4<em>x</em> > 1
… ⇒ <em>x</em> > -1/4 o <em>x</em> < -1/4
⇒ <em>x</em> ≠ -1/4
|<em>x</em> - 1| < 5 ⇒ <em>x</em> - 1 < 5 o -(<em>x</em> - 1) < 5
… ⇒ <em>x</em> - 1 < 5 o -<em>x</em> + 1 < 5
… ⇒ <em>x</em> < 6 o -<em>x</em> < 4
… ⇒ <em>x</em> < 6 o <em>x</em> > -4
⇒ -4 < <em>x</em> < 6
Answer:
Area = ab
Step-by-step explanation:
Area is length × width, so fill in a for the length and b for the width. Multiply a and b together.
A = a×b
A = ab
