Among 500 freshmen pursuing a business degree at a university, 323 are enrolled in an economics course, 205 are enrolled in a ma

Aleksandr-060686 [28]

<h3>The probability of selecting a random student who is enrolled in both the courses is 0.280.</h3>

Step-by-step explanation:

Here, the total number of freshman in the university = 500

The number of students enrolled in Economics = n(E) = 323

The number of students enrolled in Mathematics = n(M) = 205

The number of students enrolled in Both Economics and math

= n(E∩M ) = 140

Let F : Event of selecting a student who is enrolled in both the courses

So, from the given data:

$P(F) = \frac{\textrm{Total number of favorable outcomes}}{\textrm{Total number of outcomes}} \\= \frac{\textrm{Total number of students enrolled in BOTH courses}}{\textrm{Total number of students}} \\ = \frac{140}{500} = \frac{7}{25}$

So, the probability of selecting a random students who is enrolled in both the courses is $(\frac{7}{25} ) = 0.280$

Name three points that are collinear. Assume angle TSR is not a straight angle.

skelet666 [1.2K]

Answer:

TS, SR, and TR are all co-linear

Step-by-step explanation:

Regardless of where the points lie, you can connect a line segment from point T to point S, so TS are co-linear

The same goes for point S to point R

The same goes for point T to point R

The definition of a line is the shortest distance through 2 points in space, so you can make a line between any 2 points.

you invest 2,200 in an account that pats an interest rate of 8.5% compounded continuously what's the balance after 6 years

malfutka [58]

Let's find the equation.
2,200×1.085^x=y
We need x to equal 6.
2,200×1.085^6=y
2,200×1.631467508843266
3,589.23
The balance after six years is $3,589.23.

based On this data, what is a reasonable estimate of the probability that a van is the next type of vehicle rented

Aleonysh [2.5K]

The question is incomplete, the complete question is here

Shaniya owns a company that rents cars called Car Go. The following bar graph summarized the type of vehicles rented last week. Based on the data, what is a reasonable estimate of the probability that a van is the next of the vehicle rented?

The graph is attached down

Answer:

The probability that a van is the next type of vehicle rented is 25% or $\frac{1}{4}$

Step-by-step explanation:

Probability of an event = outcomes of the event ÷ total outcomes

From the attached graph

∵ The number of cars rented is 8

∵ The number of vans rented is 5

∵ The number of trucks rented is 4

∵ The number of motorcycles rented is 3

- Add all of them to find the number of vehicles rented

∴ The number of vehicles rented = 8 + 5 + 4 + 3 = 20

To find the probability of that a van is the next type of vehicle rented divide the number of the vans by the number of the vehicles

∵ The number of vans = 5

∵ The number of vehicles = 20

∴ P(van) = $\frac{5}{20}$

- Divide up and down by 5 to simplify it

∴ P(van) = $\frac{1}{4}$

- To change it to percent multiply it by 100%

∴ P(van) = $\frac{1}{4}$ × 100% = 25%

The probability that a van is the next type of vehicle rented is 25% or $\frac{1}{4}$
