An urn contains ten chips. An unknown number of chips are white' the others are red. We wish to test:

Olin [163]

Answer:

Let’s denote X to be the number of white chips in the sample and E be the event that exactly half of the chips are white. Then,

a) Find α

α = P (reject H0 | H0 is true) = P (X ≥ 2|E)

= P (X = 2|E) + P (X = 3|E),

We took two case, as we can draw only only three chips with two or more white to reject H0, it means we can only take 2 white chips or 3, not more, we get solution

= (5C2 * 5C1)/10C3 + (5C3 * 5C0)/10C3

= 0.5

So, α = 0.5

b) Find β

i) Let E1 be the event that the urn contains 6 white and 4 red chips. (As given)

β = P (accept H0 | E1) = P (X ≤ 1|E1)

= (6C0 * 4C3)/10C3 + (6C1 * 4C2)/10C3

= 1/3

= 0.333

So, β = 0.333

i) Let E2 be the event that the urn contains 7 white and 3 red chips. (As given)

β = P (accept H0 | E2) = P (X ≤ 1|E2)

= (7C0 * 3C3)/10C3 + (7C1 * 3C2)/10C3

= 11/60

= 0.183

So, β = 0.183

Help with pic below !

Because you are shifting the function to the left by 2 units, you will represent that as:

Because you are shifting the function to the left by 2 units, you will represent that as:
$f(x) = (x+2)^2-7$

Generally, if you are moving to the left, it's seen going in the negative direction, but remember since f(x) is going to the left, it means that you are solving for x. So, solve for x in (x + 2), you get x = -2. Hopefully this makes sense.

The, you are dilating the entire function in which you have to multiply the entire thing. Let's do it:
$f(x) = 3((x+2)^2-7)$

Which is equal to:
$f(x) = 3(x+2)^2 -21$

So, your answer is D. If anything doesn't make sense to you, please tell me, I'd be happy to explain!

The weather forecast says that the probability of being cloudy tomorrow is 30% and the probability of raining is 25%. If it is c

Bumek [7]

<h3>Answer:</h3>

$\large\boxed{C).\,13.5\%}$

<h3>Step-by-step explanation:</h3>

In this question, we're trying to find the probability of it being cloudy and raining.

In this case, we know that:

Probability of it being cloudy is 30%
Probability of it raining is 25% (this is necessarily not needed)
If it's cloud, the probability of it raining is 45%

With the information above, we can find the probability.

We know that from a 100% scale, the chance of it being cloudy is 30%.

We know that if it's cloudy, the chances of raining is 45%

To find the probability of it being cloudy and raining, we would multiply 0.3 (30%) by 0.45 (45%)

Solve:

$0.3*0.45=0.135\\\\\text{Move the decimal place two times to the right}\\\text{to turn it into a percent}\\\\\boxed{13.5\%}$

Your answer would be C). 13.5%

<h3>I hope this helped you out.</h3><h3>Good luck on your academics.</h3><h3>Have a fantastic day!</h3>
