There are 534 car parking spaces but 478 spaces are occupied,round to the nearest 10
suter [353]

Answer:

60

Step-by-step explanation:

If 478 out of 534 parking spaces are taken, then you will be <u>subtracting</u>. When you subtract 534 and 478 (534-478), then you get 54. Remember 5 and up round to 10. 4 and below round to 0. So 56 rounds to 60 because 6 is greater than 5.

Hope it helps!

The hourly wages of a sample of 130 system analysts are given below.
atroni [7]

Answer: b. 30%

Step-by-step explanation:

  • A measure of relative variability is known as coefficient of variation. It is the ratio of the standard deviation to the mean.

i.e. CV=\dfrac{\sigma}{\mu}

Given: mean =  \mu=90

Variance = \sigma^2 = 729

\sigma=\sqrt{729}=27

Now, CV=\dfrac{27}{90}=0.3

in percent , CV= 0.3\times100\%= 30\%

Hence, correct option is  b. 30%.

Convert the following radian angle into degrees.
NeTakaya

The degree of the radian angle 0.11 is 6.3^{\circ}

Explanation:

It is given that the radian angle is 0.11

We need to determine the degrees of the radian angle.

To convert the radian into degrees, let us multiply the radian with \left(\frac{180}{\pi}\right)

Thus, we have,

0.11\times\left(\frac{180}{\pi}\right)=\frac{19.8}{\pi}

It is given that \pi=3.14

Substituting \pi=3.14 in the above expression, we have,

\frac{19.8}{3.14} =6.303...

Rounding off to the nearest tenth, we have,

6.3^{\circ}

Thus, the degree of the radian angle 0.11 is 6.3^{\circ}
