How many tiles of 20cm by 20cm are needed for a dinning room measuring 20m?

1 answer:

BARSIC [14]3 years ago

6 0

To find the area of the dining room, take 20m x 20m=400m
The area of each tile is 20cm x 20cm=40cm.
Convert the are of the dining room to cm which is 400 x 100= 40000cm
The divide the area of the dining room by the are of the tiles to find how m,any tiles are needed.
Which is 40000cm/40cm= 1000 tiles

Brut [27]

Answer:

$P(x < -778) = 0$

Step-by-step explanation:

Given

$\bar x = 48673$

$\sigma^2 = 11282880$

$n = 143$

Required

$P(x$

First, we calculate the z score

$z = \frac{x}{\sqrt{\sigma^2}/n}$

So, we have:

$z = \frac{-778}{\sqrt{11282880}/143}$

$z = \frac{-778}{3359.0/143}$

$z = \frac{-778}{23.49}$

$z = -33.12$

So:

$P(x < -778) = P(z < -33.12)$

From z score probability, we have:

$P(x < -778) = 0$
