Can u guys help me please

Solve the compound inequality n-4 > 5 AND 2 > n + 3

Papessa [141]

Get n by itself in both inequalities

(This program doesn't allow for regular less than or greater than signs, so for the purposes of this problem I will be using less than or equal to (≤) and greater than or equal to (≥) signs)

Inequality 1:
$n-4 \geq 5 \\ n \geq 9$

Inequality 2:
$2 \geq n+3 \\ -1 \geq n$

Now that you have both of the n's by themselves, you can put the two inequalities together, like this
$-1 \geq n \geq 9$

Just keep in mind that these are supposed to be regular less than signs

Halloween Candy Halloween is Kelly's favorite holiday of the year! Based on experience, Kelly knows that on average, each house

LuckyWell [14K]

Using the normal distribution and the central limit theorem, it is found that there is an approximately 0% probability that the total number of candies Kelly will receive this year is smaller than last year.

Normal Probability Distribution

In a normal distribution with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

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

It 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, which is the percentile of X.
By the Central Limit Theorem, for n instances of a normal variable, the mean is $n\mu$ while the standard deviation is $s = \sigma\sqrt{n}$ .

In this problem:

Mean of 4 candies, hence $\mu = 4$ .
Standard deviation of 1.5 candies, hence $\sigma = 1.5$ .
She visited 35 houses, hence $n = 35, \mu = 35(4) = 140, s = 1.5\sqrt{4} = 3$

The probability is the p-value of Z when X = 122, hence:

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

By the Central Limit Theorem

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

$Z = \frac{122 - 140}{3}$

$Z = -6$

$Z = -6$ has a p-value of 0.

Approximately 0% probability that the total number of candies Kelly will receive this year is smaller than last year.

PLZ HELP ASAP what is 1.5 converted into a fraction

makvit [3.9K]

1 is a whole number, which would make the fraction a mixed fraction, and the 5 is the tenths place, so its 1 5/10

Kohls sells casual shirts for 9$ and polo shirts for 18$. Total sales were 1,080 and customers bought 4 times as many casual shi

lukranit [14]

The ratio would be 36 to 18
because 9*4=36
and 18 is 18 lol
so (calculator) 1,080/9=120
120
20*18=180
100*9=900
so

idek man this is hard as hell,I tried tho,try to do the rest of the problem from what I have set up
