The answer is, 2/4 (1/2 simplified) or 50%

Explanation:
You have 2 coins with 2 sides.
One coin only has one head and one tail, two coins have two of each.
As a result you would have 4 sides in total, but only 2 of those can be heads/tails.

The probability of that happening would be 1/2 also known as 50%.

Answer:

C) 11/24

Step-by-step explanation:

rewrite each fraction as equivalent fraction with common denominator.

LCM(6,8) is 24

5/6 = 20/24

3/8 = 9/24

The difference between 20/24 and 9/24 is 11/24

Times the two radicals together

So it's:

8*sqrt 15*5 (find common numbers between 5 and 15 which is 5)

8*sqrt(5^2*3)

8*5 sqrt3

40 sqrt 3

Hope this helped :)

Suppose that prior to conducting a coin-flipping experiment, we suspect that the coin is fair. How many times would we have to f

STALIN [3.7K]

Answer: b) 84

Step-by-step explanation:

Let p be the prior estimate of the required proportion.

As per given , we have

p =0.5 (The probability of getting heads on a fair coin is 0.5)

Significance level : $\alpha: 1-0.90=0.10\\$

Critical z-value (using z-value table ) : $z_{\alpha/2}=1.645$

Confidence interval width : w= 0.18

Thus , the margin of error : $E=\dfrac{w}{2}=0.09$

Formula to find the sample size ( if prior estimate of proportion is known.):-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2$

Substitute the values , we get

$n=0.5(1-0.5)(\dfrac{1.645}{0.09})^2$

Simplify ,

$n=83.5192901235\approx84$ [Round of to the next whole number.]

Hence, the number of times we would have to flip the coin =84

hence, the correct answer is b) 84

Help me please with this question

Gelneren [198K]

You could go both ways with this question, and they're both true:

-- circle "greatest" in both places;

-- circle "least" in both places; also true, but whatever the numbers are,
their least common factor is always ' 1 ', so it's not very useful.
