Answer:

The correct answer is 3.75+0.15n <_ (less than or equal to) 5.25

Step-by-step explanation:

I dont know how to make the less than or equal to sign

But it is right

Answer:

3.75 + 0.15n ≤ 5.25

Step-by-step explanation:

You can not spend more than $5.25 so the inequality sign must be less than or equal to

If you know the shop charges a minimum of $3.75 for a sandwich, you need to include that in your equation

The $0.15 for additional toppings is included as $0.15 multiplied by n (0.15n)

n can be from 0-10, as 10 is the most toppings you can get before you go over your spending limit and you don't have to pay for additional toppings if you don't want to.

Let the probability of success on a Bernoulli trial be 0.26. a. In five Bernoulli trials, what is the probability that there wil
andreyandreev [35.5K]

Answer:

0.3898 = 38.98% probability that there will be 4 failures

Step-by-step explanation:

A sequence of Bernoulli trials forms the binomial probability distribution.

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.

Let the probability of success on a Bernoulli trial be 0.26.

This means that p = 0.26

a. In five Bernoulli trials, what is the probability that there will be 4 failures?

Five trials means that n = 5

4 failures, so 1 success, and we have to find P(X = 1).

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

P(X = 1) = C_{5,1}.(0.26)^{1}.(0.74)^{4} = 0.3898

0.3898 = 38.98% probability that there will be 4 failures

How many people swam fewer than 30 laps?
Bas_tet [7]

Answer:

3 people

Step-by-step explanation:

Reading a stem & leaf plot can be hard!

Remember in the middle or whichever side is single digits divided by the line is your tens place values.

The 2 has two values on the other side, giving us 23 & 29 laps.

The 1 has one value on the other side, giving us 11 laps.

The 0 has no other value, so there is no data for that row.

There were 3 data points below 30, & these were 11, 23, & 29.

Hope this helped. :)
