The answer to the equation would be 27.

4(8) - 5 = 32 - 5 = 27

So pick B and D!

Hey!
So what you want to do is plug 8 for the n in the equation..
T(n) = 4*(8) - 5
T(n) = 32 - 5
T(n) = 27
The answer is D
Hope this helps!

12/-4 = pls help i don’t understand

Sveta_85 [38]

$\text {Hello! Let's Solve this equation!}$

$\text {Since there is a negative in the problem this tells us that the answer we get will be a negative.}$

$\text {Here are some tips on dividing/multiplying equations like this.}$

$\text {Multiplying/Dividing a Positive to a Positive will equal a Positive}\\\text {Multiplying/Dividing a Positive to a Negative will equal a Negative}\\\text {Multiply/Dividing a Negative to a Negative will equal a Positive}\\\text {Multiplying/Dividing a Negative to a Positive will equal a Negative}$

$\text {Now Divide!}$

$\text {12/-4=}$

$\fbox {-3}$

$\text {As you can see 4 is a negative number so our result came out as a negative number.}$

$\text {Want to see if your answer is correct? Sure! Do the opposite of Dividing and Multiply!}$

$\text {-3*-4=12}$

$\text {Best of Luck!}$

Data are drawn from a bell-shaped distribution with a mean of 25 and a standard deviation of 4. There are 1,000 observations in

Delicious77 [7]

Answer:

a. 97.72% of the observations are less than 33

b. Approximately 977 observations are less than 33.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Mean of 25 and a standard deviation of 4.

This means that $\mu = 25, \sigma = 4$

a. Approximately what percentage of the observations are less than 33?

The proportion is the p-value of Z when X = 33. So

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

$Z = \frac{33 - 25}{4}$

$Z = 2$

$Z = 2$ has a p-value of 0.9772

0.9772*100% = 97.72%

97.72% of the observations are less than 33.

b. Approximately how many observations are less than 33?

Out of 1000:

0.9772*1000 = 977.2

Approximately 977 observations are less than 33.
