Theoretically, if a month is chosen 300 times,
horsena [70]

Answer:

75 times.

Step-by-step explanation:

Well there are 12 months and 3 of them start with the letter J, so theoretically, 25% of the months chosen will start with the letter J because \frac{3}{12}=\frac{1}{4}, which is 25%. 25% of 300 (or \frac{300}{4}, for those who like fractions) is 75, so theoretically, we can expect a month that starts with the letter J 75 times.

Hope this helps!

Someone please help me with problem #7 !!!
ser-zykov [4K]

Answer: b and d

Step-by-step explanation:

Since the roots are x=2 and x=6, we can write the equation as

f(x)=a(x-2)(x-6)

Substituting in the coordinates of the vertex,

-4=a(4-2)(4-6)\\\\-4=-4a\\\\a=1

So, the equation is f(x)=(x-2)(x-6)

On expanding, we get f(x)=x^2 - 8x+12

Which equation justifies why nine to the one third power equals the cube root of nine?
AVprozaik [17]

Answer:

nine to the one third power all raised to the third power equals nine raised to the one third times three power equals nine

Step-by-step explanation:

we know that

The <u><em>Power of a Power Property</em></u> , states that :To find a power of a power, multiply the exponents

so

(a^{b})^{c}=a^{b*c}

In this problem we have

9^{\frac{1}{3}} =\sqrt[3]{9}

Remember that

\sqrt[3]{9}=9^{\frac{1}{3}}

Raise to the third power

[9^{\frac{1}{3}}]^3

Applying the power of power property

9^{\frac{3}{3}}

9^{1}

9

therefore

nine to the one third power all raised to the third power equals nine raised to the one third times three power equals nine
