Is the probability of red a simple event, complement of a

A. complement of a simple event

Answers

Answer:

Complement of an Event: All outcomes that are NOT the event. So the Complement of an event is all the other outcomes (not the ones we want). And together the Event and its Complement make all possible outcomes.

The line (in Standard Format, Ax+By=C) is 3x+6y=-17 [note: Convention is that x-coefficient is positive].
The slope of this line is (-A/B)=(-3/6)=-1/2.

All perpendicular lines have a negative reciprocal slope: 2
The equation of the perpendicular line is: 6x - 3y = D
[switch A and B and make negative; and we need point (6,3) to determine D]
6(6)-3(3)=D
36 - 9 = D
27 = D

The perpendicular line is:
6x - 3y = 27
or 2x - y - 9

Answers

Answer:

The second option is correct.

Step-by-step explanation:

If x = 5, then this happens.

1(5) - 2 < 3

5 - 2 < 3

3 < 3

That is incorrect because 3 = 3.

The second option is correct, because:

4 - 2 < 3

2 < 3

This work so the second option is correct

the perimeter of a rectangle is at least 74 cm the length of a rectangle is two more than four times the width of a rectangle what are the minimum dimensions of the rectangle

Answers

Answer:

2W+2L=perimeter=74

Step-by-step explanation:

2W=74-2L

2(2W)+2(L/2)=76

substitute 74 - 2L for 2W in the last equation to solve for L. Put that value in the first equation to find W. Check by putting both values into the last equation.

Which best describes the probability of the rolling a 7 on a number cube that is numbered from 1 through 6

Answers

Answer:

[tex]\huge\boxed{\text{Impossible}}[/tex]

Step-by-step explanation:

To find the probability of something happening, we find all the outcomes that can happen, find all the outcomes in which our criteria is met, and set that up as a fraction, where it's criteria met/total possible outcomes.

When we roll a 6-sided die, we will have 6 possible outcomes that we can roll.

1, 2, 3, 4, 5, and 6.

We can not roll anything except these 6! Since a die only has 6 sides, numbered 1-6, we will only roll these numbers.

7 is not in this list! It is impossible to roll a 7 on a die that only has 6 sides. Since 7 isn't even possible, it would be impossible to get a 7 on a 6-sided die.

Hope this helped!

A river 3m deep and 40 m wide is flowing at the rate 2km /h . how much water will fall into the sea in a minute.

Answers

Answer:

Area of river = depth × width

=3×40

[tex] = 120 {m}^{2} [/tex]

amount of water that falls into the sea ⇒

Area of river × flow rate

[tex]120 {m}^{2} \times 2 \: \frac{km}{hr} [/tex]

[tex]120 \times \frac{2 \times 1000 {m}^{2} }{(60)min} [/tex]

[tex]4000 \: \frac{ {m}^{3} }{min} [/tex]

:. [tex] {4000m}^{3} [/tex] of water falls into the sea per min.

So, [tex] {4000m}^{3} [/tex]

= 4000 × 1000 litres

= 4000000 litres

So, in 1 minute, water will fall into the sea is 4000000 litres.
