Answer:

This is a normal distribution and we can use the standard score to compute for probabilities. We compute the standard score of the given.

Explnation:

z = (x - mu)/sd

z = (2625 - 2600)/50 = 25/50 = 0.5.

Consulting the z-table, P(z <= 0.5) = 0.6915.

P(z > 0.5) = 1 - P(z <= 0.5) = 1 - 0.6915 = 0.3085.

I hope this helped! <3

An account earns simple interest $600 at 5% for 2 years find the interest earned

iVinArrow [24]

Answer:

so your answer would be 60$

Step-by-step explanation:

I = P * r * t

Here, P = $600

r = 0.05 (decimal value for 5%)

t = 2 years

Part a)

The interest earned will be:

I = P * r * t

I = 600 * 0.05 * 2

I = $60

Part b)

The balance in the account will be $600 plus the interest earned or:

$600 + 60 = $660

Answer:

127.32 yards diameter
12,732.4 square yards area

Step-by-step explanation:

The diameter can be found from the circumference using the relation ...

C = πd

d = C/π = (400 yd)/π ≈ 127.32 yd . . . . diameter

The area is ...

A = πr²

where the radius (r) is half the diameter.

A = π(63.662 yd)² ≈ 12,732.4 yd² . . . . area

_____

<em>Additional comment</em>

We have used a full-precision value for pi. If you use 3.14, your answers will be different. Your diameter will be about 127.4 yards; your area about 12,738.9 yd².
