Students in the seventh grade at Texas Intermediate School were surveyed to find out their favorite store. The graph below repre
natta225 [31]

Answer:

Option d is correct.

The number of students that chose Target as their favorite store over Ross = 4 students.

Step-by-step explanation:

The graph of the question is obtained from another brainly question on here. But uploading it will lead to deletion of this answer as it would be violating the community guidelines here.

So, I'm going to describe the graph.

The graph provided with the question is a pie chart, with each region clearly shown and the corresponding percentage for each of the students' favourite stores that come up in the survey given as

TJMax - 20%

Wal-Mart - 25%

Ross - 20%

Target - 25%

Others - 10%.

How many more students surveyed chose Target as their favorite store over Ross?

Total number of students sampled = 80

Number of students that picked Target

= 25% × 80 = 20 students

Number of students that picked Ross

= 20% × 80 = 16 students.

Number of students that chose Target as their favorite store over Ross = 20 - 16 = 4 students.

Hope this Helps!!!

Use the image below to answer the following question. Find the value of sin x® and cos yº What relationship do the ratios of sin
Flauer [41]

Answer:

sin(x) and cos(y) are equal and have ratio of 1 : 1

First find the missing hypotenuse using Pythagoras theorem:

a² + b² = c²

12² + 5² = c²

c = √144+25

c = 13

using sine rule:

sin(x) = \dfrac{opposite}{hypotenuse}

sin(x) = \dfrac{5}{13}

using cosine rule:

cos(y) = \dfrac{adjacent}{hypotenuse}

cos(y) = \dfrac{5}{13}
