same answer as if you were to divide the decimals?

Sound City sells the ClearTone-400 satellite car radio. For this radio, historical sales records over the last 100 weeks show 4

Ksivusya [100]

Answer:

See below

Step-by-step explanation:

$\bf \mu(x)$ is the average

$\bf \mu(x)=\frac{4*0+33*1+39*2+12*3+8*4+4*5}{100}=\frac{199}{100}=1.99\;radios/week$

$\bf \sigma^2(x)$ is the variance

$\bf \sigma^2(x)=\frac{4*(0-1.99)^2+33*(1-1.99)^2+39*(2-1.99)^2+12*(3-1.99)^2+8*(4-1.99)^2+4*(5-1.99)^2}{100}=\frac{128.99}{100}=1.2899$

$\bf \sigma(x)$ is the standard deviation

$\bf \sigma(x)=\sqrt{variance}$

$\bf \sigma(x)=\sqrt{1.2899}=1.1357\;radios/week$

The area of a wall to be tiled in 1.5 metres by 2.5 metres.

gregori [183]

Answer:

Step-by-step explanation:

Given that,

The area of a wall to be tiled in 1.5 metres by 2.5 metres.

Tiles are 50cm by 50cm

The tiles are £0.99 each.

We need to find the cost of the tiles in pounds.

The area of tiles will be :

$A=50\times 50\\\\A=2500\ cm^2$

Cost of 1 time = £0.99

So, for 2500 cm², total cost will be :

$C=2500\times 0.99\\\\C=\$2475$

Hence, this is the required solution.
