Answer:

p = 1

Step-by-step explanation:

-14p + 6 = -6p - 2

-14p = -6p - 8

-8p = -8

p = 1

Answer,

p = 1

Explanation,

Step 1: Add 6p to both sides

−14p + 6 + 6p = −6p − 2 + 6p

−8p + 6 = −2

Step 2: Subtract 6 from both sides

−8p + 6 − 6 = −2 − 6

-8p = -8

Step 3: Divide both sides by -8

-8p/-8 = -8/-8

= 1

Hope This Helps :-)

Does anyone know the formula for finding the area of a circles sector

NemiM [27]

Area=(Theta/2) * r^2 This should be it, obviously Theta is your angle and you should use radiants in theory.

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

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

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

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