Answer:

c. Mode

Step-by-step explanation:

Mean is the average obtained by adding all values and then dividing by the size of the values. Here, adding A and B etc is not clear.

Median is the middle value of a set of numeric values. To find a median, values should be sort-able from smallest to the largest. If there is no unique middle value, then the average of the middle values has to be taken. Here, average of the two different grades is not clear.

Mode is the value that occurs most often. Clearly C occurs most often.

Mid-range value is the mean of the difference between largest value and the smallest value. Here, difference between A and F is not clear.

Mean,median,Mid-range are applied to numeric values where mode is also suitable for categorical values.

Therefore, the most appropriate measure of central tendency for the data described is mode

Which choice is the explicit formula for the following geometric sequence?0.5, -0.1, 0.02, -0.004, 0.0008, ...
Minchanka [31]
a_1=0.5\\a_2=-0.1\\a_3=0.02\\a_4=-0.004\\a_5=0.0008\\\\a_n=a_1\cdot q^{n-1}\\\\q=a_2:a_1\to q=-0.1:0.5=-0.2\\\\a_n=0.5\cdot(-0.2)^{n-1}=0.5\cdot(-0,2)^n\cdot(-0.2)^{-1}\\\\=0.5\cdot(-0.2)^n\cdot(-5)=-2.5\cdot(-0.2)^n\\\\\boxed{a_n=-2.5\cdot(-0.2)^n}

p varies jointly as q and the square of r, and p = 200 when q = 2 and r = 3. Find p when q = 5 and r= 2.
Margarita [4]

Step-by-step explanation:

If a variables varies jointly, we can just divide it by the other variables in relation to it.

For example, since p variables jointly as q and square of r, then

\frac{p}{q {r}^{2} }  = k

where k is a constant

First, let find k. Substitute p= 200

q= 2, and r=3.

\frac{200}{2(3) {}^{2} }  = k

\frac{200}{18}  = k

\frac{100}{9}  = k

Now, since we know our constant, let find p.

\frac{p}{q {r}^{2} }  =  \frac{100}{9}

Q is 5, and r is 2.

\frac{p}{5( {2}^{2}) }  =  \frac{100}{9}

\frac{p}{20}  =  \frac{100}{9}

p =  \frac{2000}{9}

Please answer correctly, will give brainly to best answer, please do explain your answer
Liono4ka [1.6K]

Answer: 26

2³ + 4(2 + x) for x = 10

- first do 4(2 + x) which is

8+4x

- Evaluate 2 cubed

You get 2 times 2 times 2.

That would get 8

Our expression is 8 + 8+x

x = 10

Substitute the values.

It is Now eight plus 8 plus ten

So when you Calculate eight plus 8 plus 10

You will get 26
