Answer:

C) -0.89 is correlation coefficient.

Step-by-step explanation:

Given: data on graph.

TO find : what is the correlation coefficient of the linear fit of the data shown below, to the nearest hundredth.

Solution : We have given a graph

We can see from the graph in which values on x axis is increase and values on y axis decreases , as we can say correlation coefficient is negative but not perfect negative .

Therefore, C) -0.89 is correlation coefficient.

Jenny tweets 33 times a day. antonio posts 5 tweets per day. let d represent the number of given days. use an algebraic expressi

algol13

Jenny's algebraic expression:

y = 33d

where y is the total number of posts

total tweets in 5 days

y = (33)(5)

y = 165 tweets

Antonio's expression:

y = 5d

total tweets in 5 days

y = (5)(5)

y = 25 tweets

Altogether they have posted:

165 + 25 tweets = 190 tweets in five days

snow_lady [41]

Isolate z by itself:

$\frac{z}{z^4}$

To simplify variables with powers, subtract the smaller power from the bigger power:

$4 - 1 = 3$
$\frac{z}{z^4} = \frac{1}{z^3} = z^{-3}$

The exponent will be -3.
