-2z+8
You subtract 3z and -5z =2z
Than add 2+6=8
The new expression is -2z+8

What is the explicit formula for the geometric sequence with this recursive formula? a1=-7

Arisa [49]

ANSWER

D. $a_n= - 7( \frac{1}{3} )^{n - 1}$

EXPLANATION

The given explicit formula is

$a_1= - 7$

and

$a_n=\frac{1}{3} a_{n-1}$

This implies that,

$r = \frac{1}{3}$

The explicit formula is given by:

$a_n=a_{1}( \frac{1}{3} )^{n - 1}$

We substitute the known values to get;

$a_n= - 7( \frac{1}{3} )^{n - 1}$

The IQR for male data is 10, the estimated difference between medians is 2, the box plot for males is symmetric and for females, the box plot is left side skewed.

<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.

From the box plot:

Part A:

IQR for males data:

IQR = Q3 - Q1

The estimated value of Q3 is 15 (between 10 and 20)

The estimated value of Q1 is 5 (between 0 and 10)

IQR = 15 -5 = 10

Part B:

= Median(male) - Median(femal)

= 10 - 8

= 2

Part C:

The box plot for males is symmetric and for females, the box plot is left side skewed.

Part D:

There can be holidays for the outliers

Thus, the IQR for male data is 10, estimated difference between medians is 2, the box plot for males is symmetric and for females, the box plot is left side skewed.

Need help with the problem in the photo.

noname [10]

Answer:

B (1,1) & (2,-1)

Step-by-step explanation:

This is the answer because if a line was drawn through these 2 points the slope would be the same as line QR so therefore the two would be parallel.

Hope this helps :)
