The following observations 40, 42, 45, x-1, x +1, 51, 54, 62 are arranged in
Harlamova29_29 [7]

Step-by-step explanation:

Here n = 8 (even number)

\therefore \:  \frac{n}{2}  =  \frac{8}{2}  = 4 \\  \\\&\:\:   \frac{n}{2}  + 1 = 4 + 1 = 5 \\  \\ hence \:  \\ median = \frac{ {4}^{th} term +  {5}^{th} term}{2}  \\  \\  \therefore \:  49 =  \frac{x - 1 + x + 1}{2}  \\  \\  \therefore \:  49 =  \frac{2x}{2} \\  \\  \therefore \:  49 = x \\  \\  \huge \purple { \boxed{\therefore \: x = 49}}

Without solving determine the number of real solutions for each quadratic equation
snow_lady [41]

Step-by-step explanation:

b^2-4b+3=0

b²-3x-b+3=0

b(b-3)-1(b-3)=0

(b-3)(b-1)=0

either

b=3 or b=1

.

2n^2 + 7 = -4n + 5

2n²+4n+7-5=0

2n²+4n+2=0

2(n²+2n+1)=0

(n+1)²=0/2

:.n=-1

.

x - 3x^2 = 5+ 2x - x^2

0=5+ 2x - x^2-x +3x^2

0=5+x+2x²

2x²+x+5=0

comparing above equation with ax²+bx +c we get

a=2

b=1

c=5

x={-b±√(b²-4ac)}/2a ={-1±√(1²-4×2×5)}/2×1

={-1±√-39}/2

An M&amp;Ms factory produces 109,500,000 M&amp;M’s every day. About 1/5 of its M&amp;Ms are yellow. Find the number of yellow M&
densk [106]

Answer:

It's not possible to answer precisely. About 1/5 of 109,500,000 is equal to about 109,500,000*.2 which is about 21,900,000.

Step-by-step explanation:

The first thing to note is that the amount of yellow M&Ms isn't precisely 1/5th. It's about 1/5th.

So, applying the math, 109,500,000 times 1 and divided by 5 = 21,900,000, but that's not the answer, because of the uncertainty.

The answer has to be "about 21,900,000."
