Gelneren [198K]4 years ago
3 0

Answer:

Step-by-step explanation:

for y intercept

we calculate f(0) and the value is y intercept

for the slope we have 2 points (x1,y1)  and (x2,y2)

the slope is (y2-y1)/(x2-x1)

Simplify the square root of 3 times the fifth root of 3.
bogdanovich [222]

Answer:

<h2><em>Three to the three fifths power.</em></h2>

Step-by-step explanation:

The given expression is

\sqrt{3\sqrt[5]{3} }

To simplify this expression, we have to use a specific power property which allow us to transform a root into a power with a fractional exponent, the property states:

\sqrt[n]{x^{m}}=x^{\frac{m}{n}}

Applying the property, we have:

\sqrt{3\sqrt[5]{3}}=\sqrt{3(3)^{\frac{1}{5}}}=(3(3)^{\frac{1}{5}})^{\frac{1}{2}}

Now, we multiply exponents:

(3(3)^{\frac{1}{5}})^{\frac{1}{2}}\\3^{\frac{1}{2}}3^{\frac{1}{10}}

Then, we sum exponents to get the simplest form:

3^{\frac{1}{2}}3^{\frac{1}{10}}=3^{\frac{1}{2}+\frac{1}{10}} =3^{\frac{10+2}{20}}=3^{\frac{12}{20}}  \\\therefore \sqrt{3\sqrt[5]{3}}=3^{\frac{3}{5} }

Therefore, the right answer is <em>three to the three fifths power.</em>

There are 320 students in a school. 16 come to school by car. 96 walk to school. Estimate the probability that a particular stud
lorasvet [3.4K]

Answer:

a. The probability that a particular student arrives by car is \frac{1}{20} = 0.05, which equals 5%.

b. The probability that a particular student walks to school is \frac{3}{10} = 0.3, which equals 30%.

c. The probability that a particular student does not walk to school is \frac{7}{10} = 0.7, which equals 70%.

d. The probability that a particular student does not walk or come by car is \frac{13}{20} = 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.

P(A)=\frac{number of favorable cases}{number of possible cases}

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)=\frac{16}{320}

P(A)=\frac{1}{20} = 0.05, which equals 5%

<u><em>The probability that a particular student arrives by car is </em></u>\frac{1}{20}<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)=\frac{96}{320}

P(A)=\frac{3}{10} = 0.3, which equals 30%

<u><em>The probability that a particular student walks to school is </em></u>\frac{3}{10}<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)=\frac{224}{320}

P(A)=\frac{7}{10} = 0.7, which equals 70%

<u><em>The probability that a particular student does not walk to school is </em></u>\frac{7}{10}<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)=\frac{208}{320}

P(A)=\frac{13}{20} = 0.65, which equals 65%

<u><em>The probability that a particular student does not walk or come by car is </em></u>\frac{13}{20}<u><em> = 0.65, which equals 65%.</em></u>
