Answer:
Tge attached graph shows the limits of both the apples and bananas individually, and the line shows the limit of the combined fruit count. The area under the green line but within the limits of x=80 and y = 90 is the region that satisfies the inequalities.
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
The question shows an isoceles triangle, which means both sides should equal:
28=9x-8
36=9x
x=4
Answer:
(a) 81st
=NORM.INV(0.81;0;1)
(b) 19th
=NORM.INV(0.19;0;1)
(c) 76th
=NORM.INV(0.76;0;1)
(d) 24th
=NORM.INV(0.24;0;1)
(e) 11th
=NORM.INV(0.11;0;1)
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
For this case we can find the percentiles with the Norm.inv function in Excel and we got:
(a) 81st
=NORM.INV(0.81;0;1)
(b) 19th
=NORM.INV(0.19;0;1)
(c) 76th
=NORM.INV(0.76;0;1)
(d) 24th
=NORM.INV(0.24;0;1)
(e) 11th
=NORM.INV(0.11;0;1)
Law of Sines formulas and equations are used to solve the length of the sides of a triangle. Example a given triangle with sides a, b and c and given angles opposite to the sides are A, B and C. The law stated the following:
a/sinA=b/sinB=c/sinC
We can also solve the missing length of the third side once we are done solving the first and second sides of the triangle, this is called triangulation.
