How likely it is that an event will occur. you can find probabilities by reasoning mathematically or by using data collected from an experiment. p(event)

EXAMPLE: you have 4 red marlbes and 3 white marbls. the probability that you select one red marble and without replacing it/ putting it back and randomly select athoer red marble is p(red) = 4/7 times 3/6 = 2/7

also if you have 10 carrots ina bag and have 4 grapes and you contunie to pull out 3 of the carrots p(carrots) = 10 /14 (cause you add the two numbers together) times 4/ 6 (you use the number of carrots left as the denominator) what does it equal???

11,20,29, Find the 30th term.

Mekhanik [1.2K]

Answer:

372

There are already 3 terms. So, now you have to find the 30th term.

The difference of 30 - 3 is 27. Now, since you add 9 for every term, multiply it by 27.

27 x 9 = 243.

The third term is 29. So you add 29.

Your answer will be 372. Hope it helps.

1 point) Are the functions f,g, and h given below linearly independent? f(x)=e3x+cos(5x), g(x)=e3x−cos(5x), h(x)=cos(5x). If the

Fynjy0 [20]

Answer:

Functions are linearly dependent (are not linearly independent.)

Step-by-step explanation:

Remember that two functions f(x), g(x) and h(x) are said linearly independent on an interval I if the <em>only solution</em> to the equation

$\alpha f(x)+\beta g(x)+\omega h(x)=0, \ \text{for all } x\in I$

is the trivial one: α = 0, β = 0, ω = 0. If they are not linearly independent, they are called linearly dependent.

Now, let f(x), g(x) and h(x) be the functions:

$f(x)=e^{3x}+\cos(5x),$

$g(x)=e^{3x}-\cos(5x),$

$h(x)=\cos(5x).$

Then, letting α = 1, β= -1 and ω = -2, we see that:

$\alpha f(x)+\beta g(x)+ \omega h(x)=e^{3x}+\cos(5x)-e^{3x}+\cos(5x)+2\cos(5x)=0.$

Hence, the functions f(x), g(x) and h(x) are not linearly independent, or equivalently, are linearly dependent.

Sylvia surveyed her classmates at school to find out who plays sports at her school.the table below shows the number of students

Neporo4naja [7]

Answer:

Using the info you just gave,

Basketball, 8 studentsfootball, 7 studentsSoccer 12 studentsother, 13 students

We can now figure out the percentage of students that did NOT select soccer.

First, you need to add all the students together.

8 + 7 + 12 + 13

You get 40 students all together.

Now, add together the students that DID NOT choose soccer.

7 + 8 + 13 = 29

That means that 28/40 of the students did not choose soccer.

Now, convert that to a percentage.

28/40 = 0.7

To make that into a percentage, multiply by 100

Thus, the percentage of students that did not select soccer is 70%.

Hope this helped!
