Tony's hambugers shack sells hamburgers for $2 plus.40 for each topping

kirill [66]

<h3>For 5 toppings, cost of tony and bob are same</h3>

Solution:

Let "x" be the number of toppings

Given that,

Tony's hamburgers shack sells hamburgers for $2 plus $0.40 for each topping

Therefore,

Cost = 2 + 0.40x ----- eqn 1

Bob's burgers sells hamburgers for $3 dollars plus 20 cents for each topping

20 cents = $ 0.2

Therefore,

cost = 3 + 0.2x -------- eqn 2

For both the cost to be same, eqn 1 is equal to eqn 2

2 + 0.40x = 3 + 0.2x

0.40x - 0.2x = 3 - 2

0.2x = 1

Divide both sides by 0.2

x = 5

Thus, for 5 toppings, cost of tony and bob are same

An eyewitness observes a hit-and-run accident in New York City, where 95% of the cabs are yellow and 5% are blue. A police exper

Liula [17]

Answer:

0.1739 = 17.39% probability that the cab actually was blue

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Witness asserts the cab is blue.

Event B: The cab is blue.

Probability of a witness assessing that a cab is blue.

20% of 95%(yellow cab, witness assesses it is blue).

80% of 5%(blue cab, witness assesses it is blue). So

$P(A) = 0.2*0.95 + 0.8*0.05 = 0.23$

Probability of being blue and the witness assessing that it is blue.

80% of 5%. So

$P(A \cap B) = 0.8*0.05 = 0.04$

What is the probability that the cab actually was blue?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.04}{0.23} = 0.1739$

0.1739 = 17.39% probability that the cab actually was blue

If you were to flip a coin 10 times, what is the probability that it will land on heads exactly 7 out of 10 times?

bezimeni [28]

Answer:

The probability of flipping a coin 10 times and it landing on heads exactly seven times is about 0.1172 or 11.72%.

Step-by-step explanation:

We can use basic binomial distribution, which is given by the formula:

$\displaystyle P(x) = {n \choose x}p^xq^{n-x}$

Where n represent the number of trials, x represent the number of successes desired, p represent the chance of success, and q represent the chance of failure.

Since we are flipping a coin 10 times, we are conducting 10 trials. So, n = 10.

We want to probability that it lands on heads exactly 7 out of 10 times. So, the number of desired successes x is 7.

The probability of success p is 1/2.

And the probability of failure q is also 1/2.

Substituting:

$\displaystyle P(7)={10 \choose 7}\left(\frac{1}{2}\right)^7\left(\frac{1}{2}\right)^3=120\left(\frac{1}{2}\right)^{10}=\frac{120}{1024}=\frac{15}{128}\approx0.1172$

The probability of flipping a coin 10 times and it landing on heads exactly seven times is about 0.1172 or 11.72%.
