The answer is E

To solve this you need to use the Pythagorean Theorem which is a^2+b^2=c^2. This formula can help you find the missing length of any side of a right triangle.

Hope this helped!

Marco wants to buy a new smartphone that costs $495, with some additional accessories. He has already saved $75. Write and solve
antoniya [11.8K]

Marco needs to save a minimum of $420 more to buy a smartphone.

<u>Explanation:</u>

Cost of a smartphone = $495

Savings = $75

Least amount of money, m that needs to be saved = ?

Additional savings, m = Total - initial savings

                              m = $495 - $75

                              m = $420

The inequality equation would be 75 + m ≥ 495

Therefore, Marco needs to save a minimum of $420 more to buy a smartphone.

Bartholemew will draw with replacement 160 tickets at random from a box with five tickets [0, 0, 0, 1, 2]. Estimate the chance t
cupoosta [38]

Answer:

0.0786

Step-by-step explanation:

It is given that Bartholemew had drawn the replacement of 160 tickets.

There are five tickets = [0, 0, 0, 1, 2]

Now we need to find the estimate of the ticket that has 1 on it and it turns up on the 32 draws exactly.

Since the probability of the drawing 1 out of 5 tickets is given by,   $\frac{1}{5} = 0.2$

So the binomial with the parameter of n = 160 and p = 0.2, we get

P (it turns up on exactly 32 draws) = P(X = 32)

Therefore,

$C(160, 32)\times (0.2)^{32}\times (0.8)^{160-32}$

= 0.0786
