22% of all resumes received by a corporation for a management position are from females. 18 resumes will be received tomorrow.

Vladimir79 [104]

Answer:

5.80% probability that exactly 1 resume will be from females.

Step-by-step explanation:

For each resume received by the corporation, there are only two possible outcomes. Either they are from a female, or they are not. The probability of a resume received being from a female is independent from other resumes. 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.

22% of all resumes received by a corporation for a management position are from females.

This means that $p = 0.22$

18 resumes will be received tomorrow.

This means that $n = 18$

What is the probability that exactly 1 resume will be from females?

This is P(X = 1).

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

$P(X = 1) = C_{18,1}.(0.22)^{1}.(0.78)^{17} = 0.0580$

5.80% probability that exactly 1 resume will be from females.

Help me pleaseeee :)

Answer:

for a) the following answers are in order from left to right.

5, 2, 2, and 10

for b) this is the square root of three: 1.73205080757 [u can round it to the first decimal place urself! :)]

Step-by-step explanation:

b) 4 = x^2 + 1

4 - 1 = x^2 - 1

3 = x^2

so the sqaure root for 3 is 1.73205080757

The blades of a helicopter's propeller are perpendicular and congruent. The distance between consecutive blade tips is 24 feet.

Leno4ka [110]

Check the picture below.

now, recall, both blades are congruent, thus a = b, so c² = a² + b² -> c² = b² + b².

Why will the percent of change always be represented By a positive number

barxatty [35]

The percent of change will always be represented by a positive number because that change is an absolute value. Absolute values will always stay positive because the direction is ignored. It's not like a -1 or a -2, but it's a zero or a 3.
Hope this helped you out! :D
