laiz [17]

Answer:

B) 0.02

Step-by-step explanation:

<u>Use the Binomial Theorem</u>

\displaystyle P(X=x)=\binom{n}{x}p^xq^{n-x}\\\\P(X=4)=\binom{30}{4}(0.30)^4(1-0.30)^{30-4}\\\\P(X=4)=\frac{30!}{4!(30-4)!}(0.30)^4(0.70)^{26}\\ \\P(X=4)=\frac{30!}{4!(26)!}(0.30)^4(0.70)^{26}\\ \\P(X=4)=\frac{30*29*28*27}{4*3*2*1}(0.30)^4(0.70)^{26}\\ \\P(X=4)=27405(0.30)^4(0.70)^{26}\\\\P(X=4)\approx0.0208

We have the probability of success, p=0.30, and the probability of failure, q=1-0.30=0.70. The binomial coefficient, \binom{n}{k}, represents the amount of possible combinations that k items can be chosen out of n items, with its respective formula \frac{n!}{k!(n-k)!}.

Hence, the best choice for the probability that 4 students chosen at random from the class of 30 that want the next test to be on Monday will be option B, 0.02

A circle is a set of all points that are the same distance from one given point. Find an wxample that cotradicts this definition
eduard

Answer:

Part A

The given definition of a circle is the set of all points that are the same distance from one given point

One example that contradicts the definition, is the set of all points in a three dimensional plane which are equidistant from, a point, which is the definition of a sphere

Part B

The definition of a circle can be modified to include the location of the points <em>on the same plane</em>, from which we therefore have;

<em>A circle is a set of all points on a plane that are the same distance from one given point</em>

Area of a Triangle = 1/2 * base * Height

2.5 = 1/2 * 2 * h

2.5 = 1 * h

h = 2.5 /1

h = 2.5 in

In short, Your Answer would be: Option C

Hope this helps!
