I think that you are looking for the answer to step 3. Step 3 states that <EDF = <ADC. The reason for this is vertical angles. The vertical angles theorem states that 2 vertical angles are always congruent, so the correct answer for the reasoning behind step three is that vertical angles are congruent.

Answer:

Mean = 3640

Mode = 4100

Median = 3830.

Step-by-step explanation:

We are given the following data in the question:

Strength of casts (in psi):

3970,4100,3100,3200,2950,3830,4100,4050,3460

Formula:

$Mean = \displaystyle\frac{\text{Sum of all observation}}{\text{Total number of observations}}$

$\displaystyle\frac{3970+4100+3100+ 3200+ 2950+ 3830+4100+ 4050+ 3460}{9} = \displaystyle\frac{32760} {9} = 3640$

Mode is the entry with most frequency. Thus, for the given sample mode = 4100.

Median

Since n = 9 is odd,

Formula:

$Median = \displaystyle\frac{n+1}{2}th~term$

Data in ascending order:

2950,3100,3200,3460,3830,3970,4050,4100,4100

Median = 5th term = 3830.

Give a possible formula for the function below. Let A = (-1, 32) and B = (1, 8). (Note: Use the general exponential function.)

skelet666 [1.2K]

The question ask to find and compute the possible formula for the function below where as A = (-1,32) and B= (1,8). In my own calculation and further computation about the problem and also following the rule of general exponential function, the formula would be y = a*(b^x). I hope this would help

You can separate it to 6w*6w*6w so then 6*6*6=216 and w*w*w=w^3
