HELPPPPP!!!!!!!! ASAPPPPPPP!!!!!!!!!!Choose the best explanation for why the graph shown is a line of best fit.

The graph shows a line of best fit because the points fit around the line.

The graph shows a line of best fit because there is a straight line.

The graph shows a line of best fit because the association is zero.

The graph shows a line of best fit because the points are plotted evenly above and below the line.

Answers

Answer 1

Answer:

The best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

$\rm m = (n\sum xy-\sum x \sum y)/(n\sum x^2 - (\sum x)^2) \n\n\n\nrm c = (\sum y -m \sum x)/(n)$

We have a line of best fit shown in the picture.

As we know if the slope of the line is positive then the correlation will be positive.

From the line of best fit:

Because the points are evenly spaced above and below the line, the graph displays a line of best fit.

Thus, the best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

Denelle draws one card from a standard deck of 52 cards. Determine the probability of drawing either a two or a queen.

Answers

There are four queens in a deck of cards, so the probability of drawing a queen is 4/52. There is also a 4/52 chance of drawing a two. Because you can draw either a two or Queen, you add the probability of each.

4/52 + 4/52 = 8/52

8/52 can be simplified to 2/13

Evaluate S5 for 300 + 150 + 75 + … and select the correct answer below. 18.75 93.75 581.25 145.3125

Answers

It's a geometric sequence.

$300, 150, 75,... \n \n a_1=300 \n r=(a_2)/(a_1)=(150)/(300)=(1)/(2) \n \n S_n=(a_1 (1-r^n))/(1-r) \n \Downarrow \n S_5=(300(1-((1)/(2))^5))/(1-(1)/(2))=(300(1-(1)/(32)))/((1)/(2))=(300 * (31)/(32))/((1)/(2))=(75 * (31)/(8))/((1)/(2))=((2325)/(8))/((1)/(2))=(2325)/(8) * 2= \n=(2325)/(4)=581 (1)/(4)=581.25$

The answer is 581.25.

we have that

$300 + 150 + 75 +...$

Let

$a1=300\n a2=150\n a3=75$

we know that

$(a2)/(a1) =(150)/(300) \n\n (a2)/(a1)=0.5 \n \n a2=a1*0.50$

$(a3)/(a2) =(75)/(150) \n\n (a3)/(a2)=0.5 \n \n a3=a2*0.50$

$a(n+1)=an*0.50$

Is a geometric sequence

Find the value of $a4$

$a(4)=a3*0.50$

$a(4)=75*0.50$

$a(4)=37.5$

Find the value of $a5$

$a(5)=a4*0.50$

$a(5)=37.5*0.50$

$a(5)=18.75$

Find $S5$

$S5=a1+a2+a3+a4+a5\n S5=300+150+75+37.5+18.75\n S5=581.25$

therefore

the answer is

$581.25$

Alternative Method

Applying the formula

$S_n=(a_1 (1-r^n))/(1-r) \n\na_1=300 \n r=(1)/(2)\n\n S_5=(300(1-((1)/(2))^5))/(1-(1)/(2))\n\n=(300(1-(1)/(32)))/((1)/(2))\n\n=(300 * (31)/(32))/((1)/(2))\n\n=(75 * (31)/(8))/((1)/(2))\n\n=((2325)/(8))/((1)/(2))\n\n=(2325)/(8) * 2\n\n=(2325)/(4)\n\n=581 (1)/(4)\n\n=581.25$

therefore

the answer is

$581.25$

True or false, A function is a relation if and only if the x-values do not repeat in a given set

Answers

Its false because it can't repeat in a set.

False, the x-values can repeat, whereas the y-values can't repeat. If the y-values repeat, it will cause the slope to be unidentified (horizontal line).
