The dot plot shows the results of two random samples measuring the mean time, in hours, spent working out in a given week. Which statement is true?
a The students in sample 1 are better at taking tests than the students in sample 2 because the mean study time in sample 1 is noticeable less than the mean study time in sample 2.
b The students in sample 1 are better at taking tests than the students in sample 2 because the mean study time in sample 1 is noticeable greater than the mean study time in sample 2.
c The study time spent by the students in sample 1 varies more than the study time spent by the students in sample 2 because the range for sample 1 is larger.
d The study time spent by the students in sample 1 and the study time spent by the students in sample 2 vary by the same amount because the ranges are equal.

Which equations demonstrate how to solve for x, and what is the value of x?
a The equation 52 + 90 + x = 180 deomnstrates one way to solve for y, and y = 38 degrees. Since x + y = 180, then x = 142 degrees.
b The equation 52 + 90 + x = 90 deomnstrates one way to solve for y, and y = 52 degrees. Since x + y = 180, then x = 128 degrees.
c The equation 52 + 90 + x = 180 deomnstrates one way to solve for x, and x = 38 degrees.
d The equation 52 + 90 + x = 90 deomnstrates one way to solve for x, and x = 52 degrees.
Answers
Answer:
A
Step-by-step explanation:
The first step is to find yAll triangles have interior angles that add together to measure 180 degreesSince we know this you can subtract the known angle values (90 and 52) from 180180-52-90= 38 38 is your yx is an exterior angle so y+x also equals 180in order to find x just take your y value and subtract it from 180180-38=142The equation 52 + 90 + x = 180 deomnstrates one way to solve for y,
and y = 38 degrees. Since x + y = 180, then x = 142 degrees.
Calculation to find out angles :the sum of interior angles in a triangle is always 180 degrees
Add all the interior angles and make it equal to 180 degrees
[tex]90+52+y=180\\142+y=180\\[/tex]
Subtract 142 from both sides
y=38 degrees
angle y is 38 degrees
Angles y and x are linear pair of angles , the sum of linear pair is 180 degrees
[tex]y+x=180\\38+x=180[/tex]
Subtract 38 from both sides
x=142 degrees
The equation 52 + 90 + x = 180 deomnstrates one way to solve for y, and y = 38 degrees. Since x + y = 180, then x = 142 degrees.

81 is 18% of what number?
Enter your answer in the box.
Answers
Answer:
450
Step-by-step explanation:
Formula = Number x 100
Percent = 81 x 100
18 = 450
Following shows the steps on how to derive this formula
Step 1: If 18% of a number is 81, then what is 100% of that number? Setup the equation.
81
18% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
18Y = 81 x 100
18Y = 8100
Y = 8100
100 = 450
Answer:
450
Step-by-step explanation:
18% of 450 is 81. 100% of 450 is 450, therefore 18 percent of 450 equals 81. To learn how to solve 81 is 18 percent of what Number, see the step by step instructions below.
