Answer:

Diameter of the circle is 8\sqrt{2} units

Step-by-step explanation:

It is given that the vertices of the square fall on the circle.

So, the diagonal of the square is the diameter of the circle.

Also, the diagonal and the two sides of the square form a right angled triangle.

By Pythogoras theorem,

hypotenuse^{2} =side^{2} +side^{2}

= 8^{2} +8^{2}

= 2(8^{2} )

hypotenuse=8\sqrt{2} units

Hence, the diameter of the circle is 8\sqrt{2} units

If a student is 65.0 in tall, what is her height in m? (2.54 cm = 1 inch)
spayn [35]

Answer:

Height of the student=1.651m

Step-by-step explanation:

Given: Height of a student= 65.0 inch.

To find: Height of a student in meters.

Solution:

We know that 1 inch=2.54 cm, then

65.0 inch will be =2.54{\times}65.0

65.0 inch will be=165.2 cm

Also, we know that 1cm=\frac{1}{100} m, then

165.2 cm will be equal to=\frac{1}{100}{\times}165.1

165.2 cm will be equal to=1.651 meters

Therefore, the height of a student in meters will be 1.651 meters.

Four students took a national standardized test for which the mean was 500 and the standard deviation was 100. Their scores were
Len [333]
To get the z-value of the scores of the four students, we are going to use the formula for standard score or z-score.  It is score minus the mean score, then divided by standard deviation.

z= Score (X)-Mean / SD 

To find the z-value of each score, we have to use a Z table.  Using the z-score, we are to look first at the y-axis of the table which will highlight the first two digits of the z-score. Then, the x-axis for the second decimal place of the z-score.

You can use this as reference for the z-table: http://www.stat.ufl.edu/~athienit/Tables/Ztable.pdf

Mean= 500SD= 100Scores= 560, 450, 640, 530
For the student who scored 560,z= X-Mean / SDz= 560-500 / 100z= 60 / 100z= 0.6
The score is 0.6 standard deviation above the mean. The z-value is 0.7257 or 72.57%.
For the student who scored 450,z= X-Mean / SDz= 450-500 / 100z= -50 / 100z= -0.5
The score is -0.5 standard deviation above the mean. The z-value is 0.3085 or 30.85%.

For the student who scored 640,z= X-Mean / SDz= 640-500 / 100z= 140 / 100z= 1.4
The score is 1.4 standard deviation above the mean. The z-value is 0.9192 or 91.92%.
For the student who scored 530,z= X-Mean / SDz= 530-500 / 100z= 30 / 100z= 0.3
The score is 0.3 standard deviation above the mean. The z-value is 0.6179 or 61.79%.
