Answer:
And for this case we know this condition:
By the complement rule we know that:
But since the distribution is symmetrical we know that:
So then the statement for this case is FALSE.
b. False
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 if we define the random variable of interest X and we know that this random variable follows a normal distribution:
And for this case we know this condition:
By the complement rule we know that:
But since the distribution is symmetrical we know that:
So then the statement for this case is FALSE.
b. False
Answer:
The true statement is UV < US < SR ⇒ 1st statement
Step-by-step explanation:
"I have added screenshot of the complete question as well as the
diagram"
* <u><em>Lets revise the hinge theorem</em></u>
- If two sides of one triangle are congruent to two sides of another
triangle, and the measure of the included angle between these two
sides of the first triangle is greater than the measure of the included
angle of the second triangle then the length of the third side of the
first triangle is longer than the length of the third side of the second
triangle
* <em>Lets solve the problem</em>
- The figure has three triangles have a common vertex T
- m∠UTV < m∠UTS < m∠STR
- <u><em>From the hinge theorem above</em></u>
∵ The side opposite to ∠UTV is VU
∵ The side opposite to ∠UTS is US
∵ The side opposite to ∠STR is SR
∵ m∠UTV < m∠UTS < m∠STR
∴ UV < US < SR
* The true statement is UV < US < SR
