No. A scalene triangle is a triangle w/ all different side lengths, but an equilateral triangles has equal side lengths for all the side, so I think its no

svlad2 [7]

Let Jack's current point is $p$

After winning 3 consecutive games, the bonus point is given by
$b(p)=p+10$

The score after 5% = 0.05 increase is
$s(p)= (1+0.05)p=1.05p$

$(s.b)(p)=1.05(p+10)=1.05p+10.5$

nirvana33 [79]

Answer:

47.52% probability that among 10 randomly observed individuals fewer than 3 do not cover their mouth

Step-by-step explanation:

For each individual, there are only two possible outcomes. Either they cover their mouth when sneezing, or they do not. The probability of an individual covering their mouth when sneezing is independent of other individuals. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

According to a study done by Otago University, the probability a randomly selected individual will not cover his or her mouth when sneezing is 0.267.

This means that $p = 0.267$

What is the probability that among 10 randomly observed individuals fewer than 3 do not cover their mouth

10 individuals, so n = 10.

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)$

In which

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{10,0}.(0.267)^{0}.(0.733)^{10} = 0.0448$

$P(X = 1) = C_{10,1}.(0.267)^{1}.(0.733)^{9} = 0.1631$

$P(X = 2) = C_{10,2}.(0.267)^{2}.(0.733)^{8} = 0.2673$

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0448 + 0.1631 + 0.2673 = 0.4752$

47.52% probability that among 10 randomly observed individuals fewer than 3 do not cover their mouth

If a= 3 and b= -1, what is the value of ab-b’2?

ohaa [14]

a x b = -3. b x b = 1. Now whats -3 - 1? When a letter is right next to another letter without a space, that means it wants you to multiply the value of one letter by the other. for example, if x equals 2 and y equals 3, and they're right next to each other like this: xy that means you need to multiply x by y. X times Y = 2 times 3. 2x3=6. If you see a letter with a small number beside it, this means that it wants you to multiply the value of that letter by itself times the little number on the top. For example, if n equals 6, and the little number on the top right is 3, then that means you have to multiply 6 by 6 three times. 6 x 6 x 6 = 216.
