Which measurements are equal to 671 decimeters? check all that apply. 67,100 millimeters 0.671 kilometers 67.1 hectometers 6.71 decameters 6,710 centimeters

Option A , D and E are correct.

67100 millimeters, 6.71 decameters and 6,710 centimeters measurements are equal to 671 decimeters

Step-by-step explanation:

Use conversion:

1 millimeters = 0.01 decimeter

1 kilometer = 10000 decimeter

1 hectometers = 1000 decimeter.

1 decameter = 100 decimeters

1 centimeters = 0.1 decimeter

As per the statement:

We have to find which measurements are equal to 671 decimeters.

A.

67100 millimeters

Using conversion:

1 millimeters = 0.01 decimeter

then;

67100 millimeters = 671 decimeter.

B.

0.671 kilometers

Using conversion:

1 kilometer = 10000 decimeter

then;

0.671 kilometers = 6710 decimeter.

C.

67.1 hectometers

1 hectometers = 1000 decimeter.

then;

67.1 hectometers = 67100 decimeters.

D.

6.71 decameters

1 decameter = 100 decimeters

then;

6.71 decameters = 671 decimeters

E.

6,710 centimeters

1 centimeters = 0.1 decimeter

then;

6710 centimeters = 671 decimeters.

irst, find the z score of a score of 80. this is given by the formula z = (x-u)/o, where x is the score, u is the mean, and o is the standard deviation. this gives

z = (80-78)/12 = 1/6 = .1667

now, find what percentile a z score of 1/6 correlates to in the normal distribution.

a z score of 1/6 = .1667 is equivalent to the 56.36th percentile of the distribution. so the probability a score is over this is 1-.5636 = .4364

the mean of a sample mean is equal to the original mean. however, the standard deviation of a sample mean is equal to the original standard deviation divided by the square root of n (sample size). so the new standard deviation is 12/sqrt(16) = 3.

the new z score is 80-78/3 = 2/3 = .667. this is equivalent to the 74.86th percentile. so the probability that the mean will be greater than this score is 1-.7486 = .2514.

sure thing bud

hope this
