A person's metabolic rate is the rate at which the body consumes energy. Metabolic rate is important in studies of weight gain,
cupoosta [38]

Let m be mean

Mean= sum/ n

Mean= (1720+1687+1367+1614+1460+1867+1436) / 7

m= 11151 / 7

M= 1593

Mean= 1593

Standard deviation

|x-m|^2

For 1st: |1720-1593|^2=8836

For 2nd: |1687-1593|^2=10201

For 3rd: |1367-1593|^2=51076

For 4th: |1614-1593|^2=441

For 5th: |1460-1593|^2=1689

For 6th: |1867-1593|^2=75076

For 7th: |1436-1593|^2=24649

Summation of |x-m|^2 = 171968

Standard deviation sample formula is:

S.D = sqrt((summation of |x-m|^2) / n-1)

S.D=sqrt(171968/6)

S.D=sqrt(28661.33)

S.D=169.30

Standard deviation is 169.30

IF YOU HELP ME ILL WILL GIVE YOU BRAINLIST AND 50 PONITS HELP ME PLZZZZZ
labwork [276]
I think the answer is A because the data is skewed to the right 
The median (middle) isn't 10, it's 8 
The interquartile range (IQR) is 7 not 6 because you have to subtract the first and third quartile 13 - 6 = 7 not 6

Hope this helps! ;)

PLEASE DO NUMBER 1 SHOW WORK TOO PLEASE
kirill [66]

Answer:

A) False - not a right angle

B) True - it is a right angle

C) True - it is a right angle

D) False-not a right angle

Step-by-step explanation:

A) a*a+b*b=c*c (Asquared+Bsquared=C squared)

    2*2+ 3*3 = 4*4

   4+9=16

    13 does not equal 16

B) 5*5+12*12=13+13

  25+144=169

  169=169 - True

C) 3*3+4*4=5*5

    9+16=25

     25=25 (True)

D) 4+ Root of 3 = Root of 19

    False - square root of a prime number is irrational
