Answer:

the correct answer would be A. the mean is when you add up all of them and divide it by how many numbers there are which in this case is 5. and the median is the number in the middle, in this case 20, therefore when you add up all numbers in A ,you get 105 and you divide it by 5 which gives you 21. :))

Hi there!

A recipe for cake needs 3/4 of a cup of milk.
We are making 1/2 of the recipe, which means we also need half of the milk needed for the total recipe. Therefore, we can multiply 1/2 (half of the recipe) by 3/4 (the total amount of cups of milk needed for the total recipe).

\frac{1}{2} \times  \frac{3}{4} =  \frac{3  \times 1 }{2 \times 4} =  \frac{3}{8}
Hence, we need 3/8 cups of milk

Which of the following correctly completes the square for the equation below? x^2-9x=0
PolarNik [594]
The answer to this question is choice B. To complete the square, we take the coefficient on the x term, halve it, and then square it. This results in -9/2, and then 81/4. This value of 81/4 is added to both sides, allowing for factorization of the lefthand side of the equation.

Answer:

f(x) = 2^{(3x)}

Step-by-step explanation:

The given options are,

a) f(x) = 2^{(3x)}

b) f(x) = ({\frac {1}{2}})^{3x}

c) f(x) = 2 \times ({\frac {1}{3}})^{x}

d) f(x) = \frac {1}{2} \times ({\frac {1}{3}})^{x}

Now, among the given options only option (a) satisfies the criteria stated in the question i. e.,

     1. f(x) → 0 as x → - ∞  and

     2 f(0) = 1

so, the correct answer is,

f(x) = 2^{(3x)}
