In a normal distribution, 68% of the data falls within 1 standard deviation of the mean.
A. True
B. False
Answer:
True
Step-by-step explanation:
In a normal distribution, 68% of the data falls within 1 standard deviation of the mean is true.
What is a normal distribution?A normal distribution is a continuous probability distribution that describes a symmetric, bell-shaped curve of data.
It is also known as a Gaussian distribution or a bell curve.
The normal distribution is used to model many real-world phenomena, such as measurements of height, weight, blood pressure, and IQ scores, among others.
We have,
In a normal distribution, 68% of the data falls within 1 standard deviation of the mean.
This is known as the Empirical Rule or the 68-95-99.7 rule, which states that:
- approximately 68% of the data falls within one standard deviation of the mean
- approximately 95% of the data falls within two standard deviations of the mean
- approximately 99.7% of the data falls within three standard deviations of the mean.
Thus,
In a normal distribution, 68% of the data falls within 1 standard deviation of the mean is true.

Find the value of x in the triangle shown below.
Answer:
√80
Step-by-step explanation:
Pythagorean Theorem: a^2+b^2=c^2
a = 4, b = 8
4^2+8^2 = 16+64 = 80
c^2 = 80
c^2 = √80 ≈ 8.94
What is the length of a diagonal of the field??
Answer:
A I think because length is the bottom of the triangle
Answer:

Estimate the sum or the difference of 4/6+1/8
Answer:
Sum: 19/24
Step-by-step explanation:
Find the GCF (Greatest Common Factor) between the denominators, then multiple the corresponding numerators. For example: GCF of 6 and 8 is 24. 24/8 is 3, so 1/8 would turn into 3/24. 24/6 is 4, so 4/6 would turn into 16/24. Then you add the two, and you get 19/24.

Sloved by Elimination
Answer:
No solutions.
Step-by-step explanation:
When given the following system of equations,
[tex]\left \{ {x-2y=-2} \atop {3x-6y=30}} \right.[/tex]
Solve by the process of elimination. The process of elimination is when one manipulates one or both of the equations such that one of the variables is the inverse of the other variable in its corresponding equation. When one adds the system, one of the variables will cancel, and one can solve for the other variable, then back solve for the canceled variable.
In this case, one can see that all terms in the second equation have a common factor of (3), to make manipulating the equation easier, divide the entire equation by (3).
[tex]\left \{ {{x-2y=-2} \atop {3x-6y=30}} \right.[/tex]
[tex]\left \{ {{x-2y=-2} \atop {x-2y=10}} \right.[/tex]
However, in doing so, one can see that the left sides of the equation are equal, however, the right side is not. Such a statement is not possible, thus there are no solutions to this system of equations.
what is the answer???
Answer:
D
Step-by-step explanation:
A is the second best choice, but it is not the answer.
(fog)x means wherever you see an x in f(x), you put g(x)
So f(x) = f(g(x)) = x + 7 = g(x) + 7 = 1/x + 7
Since g(x) = 1/x then f(g(x)) = 1/x + 7
A wheelchair ramp is 16 feet long. The ramp sits up on a 2 foot platform. How far is it from the end of the ramp to the bottom of the platform?
Answer:
254
Step-by-step explanation:
This is basically a triangle, with a height of 2, and hypotenuse of 16.
Using the Pythagorean theorem (a^2+b^2=h^2) we can find the other side.
2^2+b^2=16^2
4+b^2=256
b^2=254
b=√254
If the perimeter of a square is 68 feet, find the approximate length of its diagonal.A. 17 feet B. 24 feet C. 38 feet D.
Find the side length:
Side = 68/4 = 17
Now use Pythagorean theorem:
Diagonal = sqrt(17^2 + 17^2)
Diagonal = sqrt(289 + 289)
Diagonal = sqrt(578)
Diagonal = 24 feet
The answer is B. 24 feet

PLEASE DON'T GIVE A LINK OR DELETE THE ANSWER BECAUSE THIS IS MY SECOND TIME POSTING THIS SO PLS PLS PLS GIVE A PROPER ANSWER TO ALL OF THE PICTURES.
Answer:
Alright, with this, its essentially asking for you to plug in X into each equation for the answer.
With the first box, it asks for y = 5 - x, given the x = -2.
y = 5-x
y=5-(-2)
y=5+2
y=7
With the second box down, it wants things a bit differently, it gives you the y value, and wants for you to find the x. Given this, this question can be done backwards for the x value.
y = 5-x
6 = 5-x
x+6= 5
x=-1
With the third one, its the same thing as with the first box.
y = 5-x
y = 5-0
y = 5
Same thing with the fourth one.
y = 5-1
y = 4
