Which expression can be simplified to find the slope of the trend line in the scatter plot?

D is 8-2
78-87

Answers

Answer 1

It can be simplified to B because it is in slope formula y-y over x-x hope this helps

Answer 2

(B) [tex]\frac{78-87}{8-2}[/tex]

The slope of the trend line:A linear relationship is depicted by a trend line. [tex]Y=mx+b[/tex], where [tex]x[/tex] is the independent variable, [tex]y[/tex] is the dependent variable, m is the slope of the line and [tex]b[/tex] is the y-intercept, is the equation for a linear relationship.Scatter plot -Data visualization that depicts the relationship between two numerical variables is known as a scatterplot. The values for the two variables are used to depict each member of the dataset as a point with [tex]x-y[/tex] coordinates that correspond to those values.

Therefore, (B) [tex]\frac{78-87}{8-2}[/tex] can be simplified to find the slope of the trend line in the scatter plot.

HL theorem for congruence states that if hypotenuse and one leg of one right triangle are congruent to the corresponding sides of the of the right triangle, both the triangles will be congruent.

By this theorem,

ΔACB ≅ ΔFED

If AB ≅ DF [Hypotenuse]

AC ≅ EF [Leg]

By these properties,

AC = EF = 12

Or BC = DF = 28

Therefore, Option (2) will be the correct option.

If lines BG and CF are parallel, then JOL and IOM and congruent triangles. Is this statement correct? Explain your answer.

Answers

Answer:

No this statement is not correct.

Step-by-step explanation:

The definition of congruent triangles are triangles with equal side lengths and equal angles. As we can see in the picture, one triangle is significantly larger than the other, so in conclusion, the statement is incorrect.

By basic definition of congruent triangles we can say that the statement

"triangle JOL and IOM and congruent triangles" is false

what are congruent triangles?

Triangle with same shape and same size are known as congruent triangle .Corresponding sides and angles of congruent triangles are equal .

Here in the given diagram it is clearly visible that size of triangle IOM and JOL is not same so they can't have same length of sides ,although corresponding angles are equal because of properties of parallel lines but for congruent triangles it's necessary that both corresponding sides and angle are equal .

Arnold has $24 to spend at the movies. His ticket is $12. He bought popcorn, candy bar, and soda. Popcorn is double the prize of the soda. The soda and candy bar are same prize. How much did he pay for the soda?

Answers

Given:

Arnold has $24 to spend at the movies.

Ticket = $12

Popcorn is double the price of the soda.

The soda and candy bar are same price.

To find:

The price for the soda.

Solution:

Let x be the price of soda.

According to the question,

Price of candy = Price of soda = x

Price of popcorn = 2(price of soda) = 2x

Total amount = Ticket + Popcorn + Soda + Candy

[tex]24=12+2x+x+x[/tex]

[tex]24=12+4x[/tex]

[tex]24-12=4x[/tex]

[tex]12=4x[/tex]

Divide both sides by 4.

[tex]\dfrac{12}{4}=x[/tex]

[tex]3=x[/tex]

Therefore, the price of soda is $3.

A scatterplot is produced to compare the number of hours that students study to their test scores. There are 25 data points, each representing a different student. The scatterplot shows a grouping of points rising from left to right. Which statement could be true?

Answers

The question is incomplete, the complete question is;

a. There is no relationship between the number of hours that students study and their test scores because the scatterplot does not have a cluster.

b. As the number of hours of studying increases, test scores decrease because the scatterplot has a cluster that increases from left to right.

c. As the number of hours of studying increases, test scores increase because the scatterplot has a cluster that increases from left to right.

d. The number of hours that students study is equal to the test scores because the scatterplot does not show a cluster.

Answer:

c. As the number of hours of studying increases, test scores increase because the scatterplot has a cluster that increases from left to right.

Step-by-step explanation:

Though we can't see the scatter plot but it makes sense from option c that as the number of hours of studying increases, test scores increase.

That option even stated that the cluster of points increases from left to right. If the scatterplot has a cluster that increases from left to right, then it follows that the test scores actually increases positively with the number of study hours.

Please help me I’m working on a math test and I’m struggling with this problem: The Aon center in Chicago is one of the worlds tallest buildings. It was built in 1973. It is 1,136 feet high and has 80 stories. If each story is of equal height, how tall is each story btw this is division (:

Answers

Answer:

They are 14.2 feet high each

Step-by-step explanation:

1136/80=14.2

Answer:

14.2 feet

Step-by-step explanation:

We know that the height of the Aon Center is 1,136 feet.

This building has 80 stories whose heights are equal.

Therefore, in order to calculate the height of each story, we must divide the height of the Aon Center by the number of stories it has.
