Answer:

The total volume of the individual drinks is

1386 cubic inches

and the total volume of the cooler is

Okay so
#1
4 for 5 would mean each single M&M is 1.25 (5/4)
9 for 25 would mean each single M&M is about 2.78 (25/9)
4 for 5 is the better deal

#2
10 for 35 is 3.50 each (35/10)
12 for 40 is about 3.34 each (40/12)

#3
85 divided by four is 21.25 meaning you'd spend about 22 cents each
the hardware store has a better deal seeing as 19 cents each is cheaper

#4
so 13 divided by 1.4 is about 9.3 so Raisin Bran has less sugar per ounce of cereal

Y’all I need help ASAP

professor190 [17]

Answer:

I'm not 100% sure, but I do think it is

0.042768

But it is asking for percentage, and says to round 3 decimal places, making it confusing whether you round 0.042768 first, or you round the percentage of 4.2768%. I would argue with your teacher, as the excuse of why this was turned in late.

Step-by-step explanation:

It is either 4.277% or 4.3%.

Yes, you may wonder why the second possibility is just a rounded form of the first answer. It is due to rounding to three decimal places first, as 0.042768 rounded to three places is 0.043 because the 7 is more than 4 blah blah blah kiddy rhymes from elementary school yeah.

That would become 4.3%.

But 0.042768 if you turn it to a percent first is 4.2768% which becomes 4.277% if you round it afterwards. Argue this to a teacher or something.

The lifespan (in days) of the common housefly is best modeled using a normal curve having mean 22 days and standard deviation 5.

Natasha_Volkova [10]

Answer:

Yes, it would be unusual.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

If $Z \leq -2$ or $Z \geq 2$ , the outcome X is considered unusual.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
