Which of the following statements are true? select all correct answers. in a normal distribution, the mean, the median, and the mode are the same. the arithmetic mean of a distribution must always be an observed value in that distribution. the median cuts a distribution of scores in half at the 50th percentile. if we correctly summed all deviations from the mean of a distribution (without squaring those deviations), we will always obtain a sum of zero. like the range, the interquartile range, is very susceptible to the influence of outliers.

each side has a different length.  

step-by-step explanation:

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

1. 523.33 cubic inches

2. 113.04 cubic inches.

3. 17.41.

4. 16.49

i think this should be your answer

hope i
