S = ut+ 16t²<br>Find the value of s when u = 2 and t = 3.

Fed [463]

Answer:

Step-by-step explanation:

Given,

u = 2

t = 3

Now, Finding the value of s

$s = ut \: + 16 {t}^{2}$

Plugging the values of u and t

$s = 2 \times 3 + 16 \times {( 3)}^{2}$

Calculate

$s = 2 \times 3 + 16 \times 9$

$s = 6 + 144$

Calculate the sum

$s = 150$

Hope this helps ..

Good luck on your assignment..

Greeley [361]

Answer:

Due to the higher z-score, Jane did better in class.

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:

Whoever's grade had the better z-score did better in class.

Mary's:

Mean of 85, standard deviation of 5, grade of 88. This means that $\mu = 85, \sigma = 5, X = 88$ . So
