Answer:

"approximately 47.%"

Step-by-step explanation:

Using the statistical function normalcdf( on my old TI-38 calculator:

normalcdf(100,130, 100, 15) returns the fraction 0.477,

so the final answer here is "approximately 47.%"

The population of a certain type of seahorse grew by 13% from year to year.
Gekata [30.6K]

Answer:  Exponential function

Step-by-step explanation:

A linear function is the formf(x)=mx+c , where m is the constant rate of change of y with respect to x and c is the y-intercept.

An exponential growth function is in the form f(x)=A(1+r)^x, where r is the rate of growth (generally in percent) and A is initial value.

If the population of a certain type of seahorse grew by 13% from year to year, then the rate of growth is 13% .

Hence it is an exponential equation.

Which data set could be represented by the boxplot shown? (1 point)
lidiya [134]

The second data set represents the boxplot because in the box plot the measure of statistics is the same as the data set option second is correct.

<h3>What is the box and whisker plot?</h3>

A box and whisker plot is a method of abstracting a set of data that is approximated using an interval scale. It's also known as a box plot. These are primarily used to interpret data.

We have given a data set and a box plot shown in the picture.

From the boxplot we can see:

Minimum value = 2

Q1 = (2+4)/2 = 3

Median = (4+6)/2 = 5

Q3 = (8+10)/2 = 9

Maximum value = 10

The second data set:

{2, 3, 3, 4, 5, 5, 8, 10, 10}

Minimum value = 2

Q1 = (2+4)/2 = 3

Median = (4+6)/2 = 5

Q3 = (8+10)/2 = 9

Maximum value = 10

Thus, the second data set represents the boxplot because in the box plot the measure of statistics is the same as the data set option second is correct.
