95.44% IQ scores are between 77 and 125

We're given,

Mean (a)=101

standard deviation (b)=12

To find : P[77 < x < 125]

Using Empirical Rule:

∴ P[77 < x < 125]  = P[\frac{77-101}{12} < \frac{x-a}{b} < \frac{125-101}{12}]\\

=P[-2 < z < 2]\\

=P[Z < 2]-P[Z < -2]\\

=0.9772-0.0228\\

=0.9544 =95.44% (approx)

Sonja [21]

Answer:

The Precambrian (or Pre-Cambrian, sometimes abbreviated pЄ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time.

A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. He started at 90 kilograms and gained
kvv77 [185]

Answer:

90(Initial Weight) + <em>W*t = 138 Kg </em>

So the Weight increased per month is 6Kg

Explanation:

The Wrestler started at 90Kg weight

After 8 months, Wrestler had a weight of 138Kg.

The weight gained by the wrestler in '<em>t'</em> months is:

138(Kg) - 90 (Kg) = 48 (Kg)

From above equation we can see that a difference of 48Kg was attained by Wrestler.

Since the question stated that, the weight increased at a constant rate, so we can calculate the weight gained each month over a period of 8 months.

Weight gained per month: 48 (Kg) / 8 (Months) = 6 (Kg) / (Month)

So now we can write the equation in terms of <em>W</em>(Gained per month) and<em> t</em>( t number months)

The equation becomes:

90Kg (Initial Weight) + <em>W.t = 138 Kg </em>

<em>( where 'W' is Weight increased per month and 't' is number of months passed)</em>
