56.25% as a decimal is 0.5625

0.5626 is equal to 5625/10000, which can be simplified to 9/16

This is because the common factor of 5625 and 10000 is 625. We divide the numerator and denominator by 625 to achieve 9/16.

<u>Answer:</u>

• mean = 61

• mode = 50

• median = 57.5

<u>Step-by-step explanation:</u>

• The mean is calculated by adding all the values together, and dividing the result by the number of values.

∴ mean = $\frac{60 + 50 + 50 + 70 + 40 + 80 + 65 + 55 + 50 + 90}{10}$

⇒ mean = $\frac{610}{10}$

⇒ mean = 61

• The mode of a set of values is the value that is the most common (has highest frequency) among them.

50 is the most common value.

∴ mode = 50

• The median is the middle-value of a set of ordered values.

∴ We have to first rearrange the set:

⇒ 40, 50, 50, 50, 55, 60, 65, 70, 80, 90

Now we need to find the middlemost value:

Since we have 10 values, which is an even number, we have to use the formula:

median = $\frac{(n/2)^{th} \space\ term \space\ + \space\ [(n/2) + 1]^{th} \space\ term }{2}$

where n is the number of values.

∴ median = $\frac{(10/2)^{th} \space\ term \space\ + \space\ [(10/2) + 1]^{th} \space\ term }{2}$

⇒ median = $\frac{5^{th} \space\ term \space\ + \space\ 6^{th} \space\ term }{2}$

The 5th and 6th terms in our ordered series are 55 and 60 respectively.

∴ median = $\frac{55 + 60}{2}$

⇒ median = 57.5

Answer:

AC and BC are $3\sqrt{2}$ or 4.24

Step-by-step explanation:

AC=BC and AB = 6 units

Let AC=BC=x units

$AB^2=AC^2+BC^2\\6^2=x^2+x^2\\6^2=2x^2$ $36=2x^2\\x^2=18\\x=\sqrt{18} =3\sqrt{2}$
