Which statements describe a residual plot for a line of best fit that is a good model for a scatterplot? Check all that apply. There are about the same number of points above the x-axis as below it. The points are randomly scattered with no clear pattern. The points lie on a line. The points lie on a curve. The number of points is equal to those in the scatterplot. The y-coordinates of the points are the same as the points in the scatterplot.

What is 1/4 of 24 solve using a tape diagram

Answers

Draw the tape diagram: a long rectangle and divide it into 4 squares in a row.
The whole rectangle represents 24 (as a whole number), you're dividing it into 4 parts because you want to know what is 1/4 of it.
Now, to find the value of each square: 24:4 = 6.
Put the number 6 in each square, and you have found your result.
1/4 of 24 is 6.

An electrical tower casts a 120-foot shadow. At the same time, a 10-footstreet sign casts a shadow of 8 feet. What is the height of the tower?

Answers

Answer:

The height of the tower is 150 ft

Step-by-step explanation:

Let the height of the tower be H feet.

The corresponding sides will then be in the same proportion.

The ratio of the shadows will be in the same proportion as the ratio of the heights.

(H)/(10)=(120)/(8)

We multiply both sides by 10 to get:

(H)/(10)* 10=(120)/(8)* 10

H=150

Therefore, the height of the tower is 150 ft

Answer:

Height of the tower = 150 foot

Step-by-step explanation:

We need to find height of the tower with 120-foot shadow.

We have a 10-foot  street sign casts a shadow of 8 feet.

\texttt{Ratio of height to shadow height =}(10)/(8)=(5)/(4)

We have

       \frac{\texttt{Height of tower}}{\texttt{Shadow height of tower}}=(5)/(4)\n\n\frac{\texttt{Height of tower}}{120}=(5)/(4)\n\n\texttt{Height of tower}=(5)/(4)* 120=150feet

Height of the tower = 150 foot
