Mrs. Gomes found that 40% of students at her high school take chemistry. She randomly surveys 12 students. What is the probabili

zlopas [31]

Answer:

The correct answer to the following question will be "0.438".

Step-by-step explanation:

Just because Mrs. Gomes finds around 40% of students in herself high school are studying chemistry.

Although each student becomes independent of one another, we may conclude:

"x" number of the students taking chemistry seems to be binomial to p = constant probability = 0.40

Given:

Number of surveys

= 12

Exactly 4 students have taken chemistry:

$=P(X\leq4)$

$=P(x=0)+P(x=1)+P(x=2)+P(x=3)+P(x=4)$

$=\Sigma_{0}^{4} C_{r}(0.4)^r(0.6)^{12-r}$

On substituting the above equation, we get the probability of approximately "0.438".

So that the above would be the appropriate answer.

#1). The length of the whole circumference is (π · D) = 12π .

   120° is 1/3 of 360°, so arc-AB is 1/3 of the whole circumference.

#2). 60° is 1/6 of 360°.
   So arc-CD is 1/6 of the whole circumference (which is given).

#3). The circumference of the circle is (π·D) = 20π .

   70° is (70°/360°) of the whole circle, so arc-XY
   is (70/360) of the whole circumference.

#4). Sorry, I don't remember anything right now about
   angles between chords.
   I hope what I've given you so far is worth 5 points.

The range of a data set is the greatest value minus the smallest value.

The greatest value here is 32, and the smallest value is 27:

$\sf Range=32-27=\boxed{\sf 5}$
