The graph below displays how many pieces of candy timmy and his five friends each received last halloween. within how many standard deviations of the mean do the values fall? a. 1 b. 4 c. 2 d. 3

(C)

Step-by-step explanation:

First, we calculate the mean of the candies.

16,19,25,32,38,40

Mean = Sum of the candies/number of persons

         = 170/6

         =28.34

Variance = ∑(value - mean)^2

               = (16-28.34)^2 + (19-28.34)^2+(25-28.34)^2+(32-28.34)^2+(38-28.34)^2+(40-28.34)^2/(n-1)

              =    98.66

Standard deviation = √variance = √98.66 = 9.93

Now to calculate the standard deviation of the mean, we will calculate the difference between maximum value and mean. Also difference between between minimum value and mean

Maximum value-mean = 40-28.34 = 11.66

                                     =11.66/9.93 = 1.17  towards the right of the mean

Minimum value-mean = -12.33

                                    -12.33/9.93 = 1.24 towards the left of the mean

Hence the standard deviation of the mean in which the values fall is approximately 2.

C.) 2

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
