A candy company claims that 25% of the candies in its bags are colored green. Steve buys 32 bags of 32 candies, randomly selects
Luden [163]

Answer:

45.88%

Step-by-step explanation:

We have in this case a binomial distribution when p = 0.25, since the probability is 25%

. The formula that we will use in excel is BINOM.DIST, separated by commas we must put the value of x, n, p and also if it is true or false. We know that n equals 32.

In this case we need to know when x = 7, 8 and 9 and add this, and thus we will obtain the probability:

P (X = 7) + P (X = 8) + P (X = 9)

Excel formulas: = BINOM.DIST (7,32,0.25, FALSE) + BINOM.DIST (8,32,0.25, FALSE) + BINOM.DIST (9,32,0.25, FALSE)

P = 0.1546 + 0.1610 + 0.1431

P = 0.4588

Probability that steve agrees with the company's claim 45.88%

Whatever% of anything is just (whatever/100) * anything.

thus 29.5% of something, is just (29.5/100) * something, and the decimal form of 29.5% is just 29.5/100 or the quotient of 29.5÷100.

Ksju [112]
1. Calculate how many hours passed between her temperature checks. 8 p.m to 8 a.m. is 12 hours.

2. Calculate the total change in temperature. 36 - 54 is -18, so the temperature went down by 18 degrees.

3. We are looking for degrees per hour, so we put derees(18) over hours (12) to get 18/12.

4. Calculate by dividing. The answer is 1.5 degrees per hour.
