babymother [125]

Answer:

120

Step-by-step explanation:

We know that 36 is 30% of total items

So our equation would be 36/? = 30/100

From there we cross multiply so 36x100 = 3600

From there, we divide 3600 by 100

Therefore, your answer is 120

What is 72.1 repeating as a fraction? Simplified.
Viefleur [7K]
The answer is quite simple after looking at it. 0.1 is a tenth. 72 is a whole number, so you would have 72 1/10.   1/10 is a tenth and 72 is still the whole number.

malfutka [58]

Answer:

Mean = 30

standard Deviation = 2.74

Step-by-step explanation:

Formula

mean = np

Standard Deviation = \sqrt{npq}

from the question = 40

P = 75% or 0.75

q = 1 - p = 1 - 75% or 1 - 0.75

To find mean

mean = 40 x 0.75

           = 30

For Standard Deviation (SD)

Standard Deviation = \sqrt{npq}

       = \sqrt{40 X 0.75 X 0.25

      = \sqrt{7.5}

:. Standard  Deviation       = 2.74

HELP PLEASE. Check picture. I have tried but cannot seem to get it.
Sauron [17]

Answer:

884^{-7}

Step-by-step explanation:

Start by simplifying the denominator of the fraction. When multiplying exponents of the same base, you can add the exponents. This is also known as the product rule.

a^x\cdot a^y=a^{x+y}

["a" is the base, and "x" and "y" are the exponents]

Using this we find...

884^{58}\cdot884^{46}=884^{58+46}=884^{104}

When dividing exponents of the same base, you can subtract the exponents. This is also knows as the quotient rule.

a^x\div a^y=a^{x-y}

Using this we find...

\frac{884^{97}}{884^{104}}=884^{97-104}=884^{-7}
