Answer:
A value two standards deviation from the mean is more likely to occur than a value three standard deviations from the mean.
Step-by-step explanation:
Standard deviation is a quantitative measure of the variability of traits of the subjects in a given population. These traits can range from age, height, weight e.t.c. This deviation is brought about by extreme or abnormal conditions, which is the reason why two deviations is more likely to occur than three deviations.
Moreover, going by the provisions of the empirical rule, If data comes from a population that is approximately symmetrical;
95% of the data will fall within two standard deviations.
99.7% will fall within three standard deviations
Find the attachment below.
Nevertheless, in a symmetrical distribution most of the data values fall around the mean. Two standard deviations is closer to the mean than 3 standard deviations hence more likely to occur.
The area of a trapezoid is:
A = area
a = base 1
b = base 2
h = height
Area = unknown
base 1 = 2.5
base 2 = 7.5
height = 2.5
^^^Plug these numbers into the formula!
A = (10/2)(2.5)
A = (5)(2.5)
A = 12.5
Hope this helped!
Answer:
B. The show technicians had trouble wiring the equipment.
Step-by-step explanation:
When the machine arrived <u>they had trouble wiring it</u>, so instead of going off to college that morning for an orientation, <u>I spent several days at the theater fixing my light/sound equipment</u>.
If it was easy, the technicians would have been able to handle it. But also, the author would not have spent several days fixing it were simple. It delayed his plans to going off to college by several days.
If you would like to know how many 0.75 pound packages can be made with 6 pounds of sunflower seeds, you can calculate this using the following steps:
6 pounds of seeds / 0.75 pound packages = 8 packages
Result: You can make 8 0.75 pound packages.
