Which statement is true regarding the traits of scatterplots

Answers

Here are the choices

The strength of a correlation is independent of whether the correlation of a scatterplot is positive or negative. A scatterplot with positive correlation can have either weak correlation or strong correlation.

The slope of a line is independent of whether the correlation of a scatterplot has positive or negative correlation. A scatterplot with a negative slope can have either positive correlation or negative correlation.

The nonlinear association of a scatterplot depends on whether it has a weak or strong correlation. A scatterplot with nonlinear association will have a strong correlation.

The nonlinear association of a scatterplot depends on whether it has a positive or negative correlation. A scatterplot with nonlinear correlation will have a negative correlation.

It's a, because if it is positive, it can either be one skinny line, or one thick fat confusing line. Positive isn't perfect.

The statement first "The strength of a correlation is independent of whether the correlation of a scatterplot is positive or negative is true.

What is correlation?

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

The correlation between the two variables, the explanatory variable and response variable can have either a negative correlation or a positive correlation depending on the slope of the regression line.

When the dots are along the regression line we can say the correlation is strong.

If the dots are not along the regression line the correlation may have a weak correlation.

Thus, the statement first "The strength of a correlation is independent of whether the correlation of a scatterplot is positive or negative. A scatterplot with a positive correlation can have either a weak correlation or a strong correlation" is true.

What is the slope called if zero is on the numerator or top of the fraction?

Answers

Slope does not exist. A zero in the numerator means you have a horizontal line.

The day after a national holiday, decorations were marked down 40%. Before the holiday, a patriotic banner cost $5.75. How much did the banner cost after the holiday? a. $1.15
b. $2.30
c. $3.45
d. $8.05

SHOW YOUR WORK PLEASE!!!

Answers

Answer:

The price after holiday is c. $3,45

Step-by-step explanation:

Patriotic banner cost $5,75

Mark down (discount) is 40%

So, the discount is $5.75 x 0,40= $2,3

The new price is the price before holiday P -

discount D

P¹= P-D

P¹=5,75-2,3

P¹= 3,45

40% down means 60% of the original price is remaining
5.75 * .6 = $3.45
C. the banner cost $3.45

Maggie has 7 tiles with pictures of plants and 2 tiles with pictures of animals. Maggie keeps all the tiles on a mat with the pictures hidden and mixes them up. She then turns one tile face up and finds the picture of a plant on it. She removes this tile from the mat and turns over another tile without looking. What is the probability that the second tile that Maggie turns over has a plant on it?

Answers

Answer:

$(3)/(4)$

Step-by-step explanation:

We are given that Maggie has 7 tiles with pictures of plants and 2 tiles with pictures of animals .

Number of tiles with picture of plants =7

Number of tiles with picture of animals =2

Total number of tiles =7+2=9

We have to find the probability that the second tile that Maggie turns over has plant on it .

When she removes one tile of picture of plant then she has number of tiles of picture of plants =6

Total number of tiles =8

Probability,P(E)= $(Number\;of\;favorable\;cases)/(Total\;number\;of\;cases)$

Using the formula then we get

The probability that she finds tile of picture of plant = $(6)/(8)=(3)/(4)$

Answer:6/8 - - - - simplified 3/4

Step-by-step explanation: removing the tile she just flipped over would be 6 plants and 2 animals so there would be 8 total tiles and you would putt the remaining tiles over it like so 6/8 meaning out of the remaining 8 tiles 6 of them are plants giving her a 6 in 8 chance or a 3 in 4 chance
