Answer:

P(Take the bus|Junior)=0.57

Step-by-step explanation:

Conditional Probability

Is a measure of the probability of the occurrence of an event, given that another event has already occurred. If event B has occurred, then the probability that event A occurs is given by:

[tex]{\displaystyle P(A\mid B)={\frac {P(A\cap B)}{P(B)}}}[/tex]

Where [tex]P(A\cap B)[/tex] is the probability that both events occur and P(B) is the probability that B occurs.

The two-way table shows statistics of students and we are interested to find the probability that, given the student is a junior (let's call it event B), they also take the bus (Event A). Thus, the probability we need to calculate is:

[tex]\displaystyle P(A\mid B)={\frac {P(A\cap B)}{P(B)}}[/tex]

Checking on the table, we can see that both events occur when the row and the column of both events coincide, i.e. 20 students out of a total of 100 students in total. Thus:

[tex]\displaystyle P(A\cap B)=\frac {20}{100}=0.2[/tex]

The probability that a student is classified as Junior is

[tex]\displaystyle P(B)=\frac {35}{100}=0.35[/tex]

The conditional probability is:

[tex]\displaystyle P(A\mid B)=\frac {0.2}{0.35}=0.5714[/tex]

P(Take the bus|Junior)=0.57

Answer: >14 I think

Explanation:

Let they be x.

Cost of textbooks + laptops cant greater than total amount.

(cost of 1 textbooks * number of textbooks) + (cost of 1 laptop * number of laptops ≤ 6500

(30*116) + (x*439) ≤ 6500

3480 + 439x ≤ 6500

439x ≤ 3020

x ≤ 6.8(approx)

Last natural number is 6, says, they can buy 6 laptops at max.

The length of the rectangular room will be;

⇒ 18 feet

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The area of a rectangular room = 162 square feet

The width of the room = 9 feet.

Now,

Since, we know that;

Area of Rectangle = Length x Width

Let The length of the room = y feet

Substitute all the given values, we get;

The area of a rectangular room = Length x Width

162 = y x 9

Divide by 9, we get;

y = 162 / 9

y = 18 feet.

Thus, The length of the rectangular room will be;

⇒ 18 feet

Answer:

Clay's finishing time is 1.68 standard deviation above the mean finishing time for men.

Step-by-step explanation:

In statistics, a standardized score is the number of standard deviations an observation or data point is from the mean.

Let us consider a random variable, X that follows a normal distribution, N (µ, σ²).

Then Z is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is,

[tex]Z=\frac{x-\mu}{\sigma}\sim N(0, 1)[/tex]

This, z-score is known as the standardized score.

It is provided that the distribution of finishing time for men (say, X) was approximately normal with mean µ = 242 minutes and standard deviation σ = 29 minutes.

The finishing time for Clay was x = 289 minutes.

Compute Clay's z-score as follows:

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

   [tex]=\frac{289-242}{29}\\\\=1.67857143\\\\\approx 1.68[/tex]

Thus, Clay's standardized score is 1.68.

That is, Clay's finishing time is 1.68 standard deviation above the mean finishing time for men.
