The second term is represents the SPEED or velocity of the ball, and is the coefficient of the time ( ' t ' ) term.

h(t) = -16t^2 + (50 ft/sec)t + (initial height)          *(This is just an example.)

andrew-mc [135]

The cost of the plane ticket will be $324.12.

<h3>What are percentages?</h3>

The Percentage is defined as representing any number with respect to the 100. It is denoted by the sign%.

Given that:-

Guadalupe buys a plane ticket to visit family. The ticket costs $420.94 for a full trip. The airline has a discount of 27% for new customers.

The discount on the ticket

C = 420.94 x ( 27 / 100 )

C = 113.65

The cost of the ticket:-

= 420.94 - 113.65

= $324.12

Therefore the cost of the plane ticket will be $324.12.

An aptitude test has a mean score of 80 and a standard deviation of 5. The population of scores is normally distributed. What pr
konstantin123 [22]

Answer:

2.28% of tests has scores over 90.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

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 problem, we have that:

\mu = 80, \sigma = 5

What proportion of tests has scores over 90?

This proportion is 1 subtracted by the pvalue of Z when X = 90. So

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

Z = \frac{90 - 80}{5}

Z = 2

Z = 2 has a pvalue of 0.9772.

So 1-0.9772 = 0.0228 = 2.28% of tests has scores over 90.
