Hi there!

»»————-　★　————-««

I believe your answer is:

No.

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

If we mark the point at (3, -3), the we can tell that the point does not lie in any shaded region.
This means that it is NOT a solution to the system.

See the graph attached.

B) 43 rounding to greatest place value=40

Marco Weighs 40 Pounds.Its Because 3x4=6+37=43.Last When You Round 43 You Have To Round To The Greatest Place Value.So When You Round The 3 Is Low So You Change It To 0 And The 4 Stays The Same

1+4x=-5+7x what does x equal<br>

katrin [286]

Answer:

x = 2

Step-by-step explanation:

Given

1 + 4x = - 5 + 7x ( subtract 7x from both sides )

1 - 3x = - 5 ( subtract 1 from both sides )

- 3x = - 6 ( divide both sides by - 3 )

x = 2

A bag contains 6 red balls and 5 black balls . Two balls are picked , one after the other . Find the probability that :

Kaylis [27]

Answer:

<u>There are:</u>

6 red balls - R
5 black balls - B
Total number = 11 balls

<h3>A. Without replacement</h3>

i. <u>Two blacks </u>

P(BB) = 5/11*4/10 = 2/11

ii. <u>The first is black</u>

P(B) = 5/11

or, alternatively

P(BR or BB) = 5/11*6/10 + 2/11 = 3/11 + 2/11 = 5/11

iii. <u>Both are of same colour</u>

P(BB or RR) = 2/11 + 6/11*5/10 = 2/11 + 3/11 = 5/11

<h3>B. With replacement</h3>

i. <u>Two blacks </u>

P(BB) = 5/11*5/11 = 25/121

ii. <u>The first is black</u>

P(B) = 5/11

or alternatively

P(BR or BB) = 5/11*6/11 + 25/121 = 30/121 + 25/121 = 55/121 = 5/11

iii. <u>Both are of same colour</u>

P(BB or RR) = 5/11*5/11 + 6/11*6/11 = 25/121 + 36/121 = 61/121

Find the area of a regular hexagon with an apothem 17.3 miles long and a side 20 miles long

Zinaida [17]

The area of a hexagon is $\frac{3 \sqrt{3} }{2} a^{2}$ where a = one side

$\frac{3 \sqrt{3} }{2} 20^{2}$

$\frac{3*200 \sqrt{3} }{2}$

$\frac{600 \sqrt{3} }{2}$

$300 \sqrt{3}$ ≈ 1038 mi²
