What is 48 months rounded to nearest hundredth ?

Estimation is useful in all mathematics operations. Tell whether the answer to this problem is sensible 18 - 5 = 23

noname [10]

Answer:

It is not sensible.

explanation:

You are subtracting, so there is no way you could get a larger number. If this was addition, it would be sensible.

Theoretical Probability (Pink Band) - 19/37
Their are 95 pink rubber bands (numerator) and when adding 95+90 = 185 (denominator) to get the theoretical probability you would get 95/185 which when simplified by the factor of 5 would be the same thing as 19/37.

Theoretical Probability (Brown Band) - 18/37

Their are 90 brown rubber bands (numerator) and we already know that are denominator will be 185 so we would get 90/185. This fraction is also divisible by a factor of 5 so when simplified you would get 18/37.

Experimental Probability (Pink/Brown Band) - 12/23 and 11/23

Pink Band: Their is a 36 (numerator) out of (36+33) 69 (denominator) chance of pulling a pink band so it would be written as 36/69 which is divisible by 3 and when simplified is written as 12/23.

Brown Band: Their is a 33 (numerator) out of our already known denominator 69 chance of pulling a brown band. When written as a fraction this would be 33/69 which is also divisible by 3 and when simplified 11/23.

We can conclude with this data that their is a slightly higher chance of pulling a pink rubber band compared to the experimental probability of picking a brown rubber band because we know that 12/23 > 11/23.

Four causes of solar eclips

adell [148]

Answer:

A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth's surface

If one zero of the polynomial 2x² + 3x + λ is 1/2, find the value of λ and other zero.

ivanzaharov [21]

The value of λ is - 2 and other zero is also - 2.

<h3>Justification:</h3>

Let <u>p(x) = 2x² + 3x + λ</u>

<u>Its one zero is 1/2</u>, so p(1/2) = 0

p(1/2) = 2 × (1/2)² + 3 × 1/2 × λ

⇒ 1/2 + 3/2 + λ = 0 ⇒ 4/2 + λ = 0

⇒ 2 + λ = 0 ⇒ λ = - 2

<u>Let the other zero be α</u>,

Then α + 1/2 = - 3/2 ⇒α = - 3/2 - 1/2 = - 2

A rectangular garden is fenced on three sides with a wall forming on the fourth side. The total length of the fence is 120m. The

creativ13 [48]

Answer:

20m by 80m

Step-by-step explanation:

Let the dimension of the garden be x by y

The garden is fenced on three sides with a perimeter of 120m

Perimeter of the three sides = 2x+y

Therefore:

2x+y=120

The Area of the garden = $1600m^2$

xy=1600

From the first equation, y=120-2x

Substitute y=120-2x into xy=1600

xy=1600

x(120-2x)=1600

$120x-2x^2=1600\\2x^2-120x+1600=0\\2x^2-80x-40x+1600=0\\2x(x-40)-40(x-40)=0\\(2x-40)(x-40)=0\\2x-40=0\: x-40=0\\x=20 \: or \: x=40$

Recall,

xy=1600

When x=20, 20y=1600===>y=80

When x=40, 40y=1600===>y=40

So we have the pair (20,80) and (40,40).

However since we are told that the garden is rectangular, we pick the dimension with unequal sides.

The dimension of the garden is 20m by 80m.
