Answer:
150 units
Step-by-step explanation:
you count the lines and each line is 50
1.To find the percentage of 150 is 96 you do:96 divided by 150 multiply by 100=64%
2. Multiply 3.6 by 225%
=8.1
3. 46.6 repeated
Answer:
<u>The correct answer is z = 1.2</u>
Step-by-step explanation:
μ or average income = US$ 3,000
σ or standard deviation = US$ 250
Income in a given month = US$ 3,300
For calculating the z score, we use the following formula:
z = (x – μ) / σ
z = (3,300 – 3,000 / 250)
z = 300/250
z = 6/5 = 1.2
Interpreting z
A Z score tells us how many units of standard deviation (1.2 in this case)from the average a given score is, that is, we do not count in quantity of points, but in quantities of standard deviations. To use the Z score we require the distribution to be normal and to know the average and standard deviation of the scores.
Answer:
30 degrees
Step-by-step explanation:
Because lines AB and CD are parallel, the angle rules such as same side interior angles, or opposite side exterior angles. Angle 4 and angle 8 are corresponding angles, which means that these angles are congruent. That means that measure of angle 8 would be 30 degrees.
