Answer:
The height of the dog house = 4 feet.
Step-by-step explanation:
Given:
The shape of the dog house is like a tent.
The slant heights of the house is 5 feet.
The bottom of the house is 6 feet across.
To find the height of the dog house at its tallest point.
Solution:
On drawing the figure of the dog house in the shape of a tent, we find out that the tallest point would be at the midpoint of the bottom of the house.
Thus, we ave a right triangle, of which one leg = and hypotenuse =
<em>Applying Pythagorean theorem to find the measure of the other leg which is the height of the house.</em>
Plugging in values.
Subtracting both sides by 9.
Taking square root both sides.
Thus, the height of the dog house = 4 feet.
Answer:
a. The probability that a particular student arrives by car is = 0.05, which equals 5%.
b. The probability that a particular student walks to school is = 0.3, which equals 30%.
c. The probability that a particular student does not walk to school is = 0.7, which equals 70%.
d. The probability that a particular student does not walk or come by car is = 0.65, which equals 65%.
Step-by-step explanation:
Probability is the greater or lesser possibility of a certain event occurring. In other words, probability establishes a relationship between the number of favorable events and the total number of possible events. Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.
In this case, the number of possible cases is always the same, which is equal to the total number of students. So the number of possible cases is 320 students. The number of favorable cases varies as follows:
a. Number of favorable cases= number of students that arrive by car= 16
So:
P(A)= = 0.05, which equals 5%
<u><em>The probability that a particular student arrives by car is </em></u><u><em> = 0.05, which equals 5%.</em></u>
b. Number of favorable cases= number of students that walk to school= 96
So:
P(A)= = 0.3, which equals 30%
<u><em>The probability that a particular student walks to school is </em></u><u><em> = 0.3, which equals 30%.</em></u>
c. Number of favorable cases= number of students that do not walk to school = 320 students - number of students that walk to school= 320 students - 96 students= 224 students
So:
P(A)= = 0.7, which equals 70%
<u><em>The probability that a particular student does not walk to school is </em></u><u><em> = 0.7, which equals 70%.</em></u>
d. Number of favorable cases= number of students that do not walk or come by car= 320 students - number of students that walk to school - number of students that arrive by car= 320 students - 96 students - 16 students= 208 students
So:
P(A)= = 0.65, which equals 65%
<u><em>The probability that a particular student does not walk or come by car is </em></u><u><em> = 0.65, which equals 65%.</em></u>
