Answer:
Step-by-step explanation:
Mathematics is a necessary skill that people use throughout their lives, such as when they travel, use money, or keep track of time. Therefore, mathematics is an important skill to learn at school. Unfortunately, many children and adults feel stressed and anxious when they have to do math. People who experience feelings of stress when faced with math-related situations may be experiencing what is called “math anxiety.” Math anxiety affects many people and is related to poor math ability in school and later during adulthood. Researchers have studied how math anxiety first appears, what is happening in the brain when people experience math anxiety, and how to best help people who are suffering with math anxiety.Researchers are also interested in how math anxiety develops. Although research has shown that math anxiety and math abilities are related [1], no study so far has been able to tell us which comes first. In other words, we do not know if being bad at math causes math anxiety, or if having math anxiety makes people bad at math.
Researchers have two ideas about how math anxiety might develop. One idea is that children who struggle with learning numbers when they are very young are more likely to develop math anxiety when they start going to school. This idea has not yet been tested in children. Another idea is that math anxiety develops in children who experience certain kinds of social situations that influence the child’s thoughts or feelings. This means that the child’s emotions, opinions, or behaviors are affected by things that other people say or do. 7/6

Answer:
1/2 < 3/5 < 2/3 < 5/6
Step-by-step explanation:
Using the given inputs:
1/2 5/6 2/3 3/5
The least common denominator (LCD) is: 30.
Rewriting as equivalent fractions with the LCD:
1/2 5/6 2/3 3/5
15/30 25/30 20/30 18/30
Sorting this table by the numerators of the equivalent fractions in order from least to greatest:
1/2 3/5 2/3 5/6
15/30 < 18/30 < 20/30 < 25/30
Therefore, the sorted inputs in order from least to greatest is:
1/2 < 3/5 < 2/3 < 5/6
Tan(ø) is 2/3
Cot is the inverse of Tan.
1.5 is technically 3/2
The inverse of 3/2 is 2/3
Answer:
14.19% probability that exactly three of the twelve support the increase.
Step-by-step explanation:
For each Missourian, there are only two possible outcomes. Either they support the increase, or they do not. The probability of a Missourian supporting the increase is independent of other Missourians. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
40% of Missourians favor increasing the minimum wage.
This means that 
Twelve Missourians are selected at random and asked whether they support the increase.
This means that 
Find the probability that exactly three of the twelve support the increase.
This is P(X = 3).
14.19% probability that exactly three of the twelve support the increase.
Answer: ZB = 48 degree
Explanation:
Complementary angle means 2 angel add together and create a right angle (90 degree).
Thus, ZA + ZB = 90 degree
But ZA = 42 degree
=> 42 degree + ZB = 90 degree
=> ZB = (90 - 42)degree
=> ZB = 48 degree
