Answer:

$22

Step-by-step explanation:

tax and the tip increase the price paid for the meal

she paid 15 + 10 = 25% more than the price of her meal

p = original price

1.15 x p = 27,50

p = 27.50 / 1.15 = 22

A binomial probability experiment is conducted with given parameters. Compute the probability of x successes in the n independen
snow_lady [41]

Answer:

P(X = 4) = 0.1876

Step-by-step explanation:

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.

In this question:

n = 15, p = 0.2

We want P(X = 4). So

P(X = 4) = C_{15,4}.(0.2)^{4}.(0.8)^{11} = 0.1876

Pls explain why no pls and thank u​
seropon [69]

Answer:

Step-by-step explanation:

So we have : c + 2.5 < 4.3

And it's asking whether c = 1.8 is a solution.

Substitue c = 1.8 in, we get :

1.8 + 2.5 < 4.3
4.3 < 4.3 (not true)

So, c = 1.8 is NOT a solution.
