To solve this problem, let us first define what
probability means in this case. It would be:
Probability = (number of colors to choose from) / (total
number of colors)
There are a total of 5 colors on the spinner. The number
of colors to choose from spins 1 to 8 would be 5 out of 5, while for the last
spin 9 the number of colors to choose from would only be brown so that would be
1 out of 5. The total probability would be the product of the probability of
each spins, therefore:
<span>Probability = 1st spin * 2nd spin * 3rd
spin * 4th spin * 5th spin * 6th spin * 7th
spin * 8th spin * 9th spin</span>
Probability = (5/5) *(5/5) *(5/5) *(5/5) *(5/5) *(5/5) *(5/5)
*(5/5) * (1/5)
Probability = 0.2
<span>There is a 20% chance to get brown on the last spin.</span>
Answer:
Step-by-step explanation:
This study investigated three mathematics teachers' construction process of geometric structures using compass and straightedge. The teacher-student-tool interaction was analysed. The study consists of the use of a compass and straightedge by the teachers, the ideas of the teachers about their use, and the observations regarding the learning process during the construction of the geometric structures. A semi-structured interview was conducted with the teachers about the importance of the use of a compass and straightedge to construct geometric structures. It was found that teachers taught compass and straightedge constructions in a rote manner where learning is little more than steps in a process. The study concludes with some suggestions for the use of a compass and straightedge in mathematics classes based on the research results. SUMMARY Purpose and significance: For more than 2,000 years, the way in which geometric structures could be constructed with the help of compasses and straightedges has caught the attention of mathematicians. Nowadays, mathematics curriculums place an emphasis on the use of the compass and straightedge. The compass and straightedge is more important in constructing geometric structures than other drawing tools such as rulers and protractors. Because steps taken with a compass and straightedge cannot be seen at first glance and this situation become a problem for students. However, 'doing compass and straightedge construction early in the course helps students to understand properties of figures'
Using the tangent rule:
Tangent(angle) = Opposite leg / Adjacent leg
We will use the 23 degree angle to solve for x.
Tangent(23) = X / 6
x = 6 * tangent(23)
x = 2.5
Answer:
3.50
Step-by-step explanation:
because first we will divide 14 by the number of popcorns and 1 drink inn which we get 7 and then we will dive by the number of popcorns we will then get 3.50 that is the answer.
