The total prize money is 200+100 which is 300

There is 100 tickets sold for $5 each so the people selling the tickets earn $500 and use $300 for prize money.

A radio station claims that the amount of advertising per hour of broadcast time has an average of 13 minutes and a standard dev

zimovet [89]

Answer:

$Z = 3.33$

Step-by-step explanation:

Z-score:

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.

In this question:

$\mu = 13, \sigma = 1.2$

You listen to the radio station for 1 hour, at a randomly selected time, and carefully observe that the amount of advertising time is equal to 17 minutes. Calculate the z-score for this amount of advertising time.

We have to find Z when X = 17. So

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

$Z = \frac{17 - 13}{1.2}$

$Z = 3.33$

Solve 1/p+1/s=1 for p

jekas [21]

Answer:

Step-by-step explanation:

Multiply through by the L. C. M which is PS.

1/p*ps+1/s*ps=1*ps

P+p=ps

2p=ps

Divide both sides by 2

2p/2=ps/2

P=ps/2

Find the lest number which is exactly divisible by 36 & 90 Maths

prisoha [69]

Answer:

Step-by-step explanation:

You need to find the HCF of 36 and 90.

<u>Prime factors of each:</u>

36 = 2*2*3*3
90 = 2*3*3*5

<u>HCF includes all prime factors of both numbers:</u>

HCF(36, 90) = 2*2*3*3*5 = 180
