Grayson measured a line to be 10.9 inches long. If the actual length of the line is 13.4 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
The percent error of the measurement, to the nearest tenth of a percent is 18.6%
Calculating percent errorThe formula for calculating the percent error is expressed as:
%error = actual - measure/actual * 100
Given the following
actual length = 13.4 in
Measured =10.9in
Substitute
%error = 13.4-10.9/13.4 * 100
%error = 2.5/13.4 * 100
%error = 18.65%
Hence the percent error of the measurement, to the nearest tenth of a percent is 18.6%

A debate team consists of five freshmen and four sophomores. (Everyone is distinguishable.) How many ways can they stand in line, so that at least two of the freshmen are standing next to each other
Using the arrangements formula, it is found that they can stand in the line in 80,640 ways.
What is the arrangements formula?The number of possible arrangements of n elements is given by the factorial of n, that is:
[tex]A_n = n![/tex]
In this problem, we have that:
The 2 freshmen are in 2! positions, in any of the 8 positions from 1 to 8.The other 7 students are arranged in 7! positions.Hence the number of ways in which they can be lined up is given by:
N = 2! x 8 x 7! = 80,640.

Solve for x. Round your answer to the nearest tenth if necessary.
Answer: 8.8
Step-by-step explanation:
Because [tex]\angle S \cong \angle S[/tex] by the reflexive property, we know that [tex]\triangle STU \sim \triangle SQR[/tex] by AA.
So, by the triangle proportionality theorem,
[tex]\frac{x}{5.3}=\frac{11.1}{6.7}\\x=(11.1/6.7)(5.3) \approx \boxed{8.8}[/tex]
Can i have some help Please! (Brainliest As Well if it lets me) Pick question 16 or 17 to answer i only have to do one Be specific in your comparisons - think about K (dilation scale factor) and how K changed for circumference versus area. You will need to look up the formula for surface area of a sphere.
For problem 17, if you double the diameter of the moon, then the surface increases by a factor of 4 and the volume by a factor of 8.
How to compare the change in surface and volume?
Let's answer question 17.
Remember that for a sphere of radius R, the volume is:
[tex]V = (4/3)*pi*R^3[/tex]
And the surface area is:
[tex]S = 4*pi*R^2[/tex]
So the volume depends on the cube of the radius and the surface on the square of the radius.
Now, if we double the diameter of the moon, then we also double the radius.
So the new volume will be:
[tex]V' = (4/3)*pi*(2*R)^3 = 8*[(4/3)*pi*R^3] = 8*V[/tex]
The new volume is 8 times the original volume.
And for the surface:
[tex]S' = 4*pi*(2*R)^2 = 4*[4*pi*R^2] = 4*S[/tex]
So the new surface is 4 times the original surface.

You flip a fair coin 25 times in the air. what is the relative frequency with which the coin will land on tails 12 of those times?
For the given experiment, the relative frequency of getting tails is:
R = (12/25)*100% =48%
How to get the relative frequency?
If we perform an experiment N times, and out of these N times, K times we get a given outcome (Where K is a number equal to or smaller than N).
The relative frequency of that particular outcome is given by the quotient between the number of times that we got that outcome and the total number of times that the experiment was performed.
In this case, the experiment is performed 25 times, and 12 times we get tails, then the relative frequency for getting tails is:
R = 12/25
If we want to write it in percentage form, then we get:
R = (12/25)*100% =48%

find the value of x to the tenths place
Answer:
x = 15
[x = 15.0]
Step-by-step explanation:
we can find the length of the hypotenuse of a right triangle using the Pythagorean theorem
[note: "c" is what they are referring to as "x" here]
a² + b² = c²
a : 12
b : 9
[c = hypotenuse/x/unknown side]
12² + 9² = c²
144 + 81 = c²
225 = c²
√225 = √c²
15 = c

2. Which statement is false about the relationship of the sides in the triangle shown in the picture below?
x=3
none of these are false.
x=1
x=7
Based on the triangle inequality theorem, the that is false about the relationship of the side of the triangle given is: D. x = 7.
What is the Triangle Inequality Theorem?The triangle inequality theorem holds that the length of any side of a triangle is less than the sum of the length of the sides of the other two sides.
Applying the triangle inequality theorem, it means the following should be true for any value of x given:
x + 2 + x + 3 > 3x - 2
2x + 5 > 3x - 2
Plug in x = 3 to find out:
2(3) + 5 > 3(3) - 2
11 > 4 (True)
Plug in x = 1 to find out:
2(1) + 5 > 3(1) - 2
8 > 2 (True)
Plug in x = 7 to find out:
2(7) + 5 > 3(7) - 2
19 > 19 (FALSE)
Therefore, the false statement is: D. x = 7.
