100 points if you tell me what is range
Answer:
Difference in large and small numbers, higher or smaller value.
Answer:
The range is the difference between the largest and smallest numbers. If you are talking in math.
Example 1: 1, 2, 5, 6, 7
so the smallest number is 1 and the largest number is 7 so 7-1=6
The range is 6.
Example 2: 16, 19, 10, 17, 42
now we have a data set that is not in order. First step is to order them:
10, 16, 17, 19, 42
Next take the smallest and largest number and subtract them: 42-10=32
The range is 32.

If Mr. Kim need to 5/8 yard of wire for a project he has a stick that is 1/8 yard long how many 1/8 in your lungs links does he need to measure to get 5/8 of a yard long
Answer:
5 stick lengths
Step-by-step explanation:
The question is not structured well. However, the following can be deduced
[tex]Wire = \frac{5}{8}yd[/tex]
[tex]Stick = \frac{1}{8}yd[/tex]
Required
How many of the stick length can be gotten from the wire length
To do this, we simply divide the length of the wire by the length of the stick.
So, we have:
[tex]Number = \frac{Wire}{Stick}[/tex]
[tex]Number = \frac{5/8yd}{1/8yd}[/tex]
[tex]Number = \frac{5/8}{1/8}[/tex]
Using a calculator, we have:
[tex]Number = 5[/tex]

The triangle and square have equal perimeters. What is the perimeter of the triangle?
A. 18
B. 4
C. 12
D. 32
E. 16
F. 24
Answer:
E. 16
Step-by-step explanation:
Perimeter of the triangle = 4x+4x+(x+7)
Perimeter of square = 4(x+3)
We know that the perimeters are equal so we can form an equation to solve for x:
9x+7 = 4x + 12
Now we can subtract 4x from both sides to move the xs to the left side, and the same with the 7 so we have the variable on one side and the constant on the other:
9x+7-7-4x=12+4x-4x-7
5x = 5
Now we divide both sides by 5 to get:
5x/5 = 5/5
x = 1
Now we can use this value to figure out the perimeter of the triangle:
P = 9x + 7
x=1, substitute into equation:
P = 9(1) + 7
P = 16
Hope this helped!
Which equation shows that the Pythagorean identity is true for ø = 270º?
Select the equation that is in the form sin^2ø+cos^2ø=1
Answer: (a)
Step-by-step explanation:
Given
angle is [tex]270^{\circ}[/tex]
Sine and cosine at this angle is
[tex]\Rightarrow \sin 270^{\circ}=-1\\\Rightarrow \cos 270^{\circ}=0[/tex]
Put the values in the identity [tex]\sin ^2\phi +\cos^2 \phi=1[/tex]
[tex]\Rightarrow (-1)^2+(0)^2=1[/tex]
The same thing is depicted by option (a)
The equation sin²ø + cos²ø = 1 is written as (-1)² + 0² = 1. Then the correct option is A.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The equation is given below.
sin²ø + cos²ø = 1
We know that the ø = 270°. Then we have
sin 270° = -1
cos 270° = 0
Then the equation will be
(-1)² + 0² = 1
Then the correct option is A.

A group of friends are dining at a pizza parlor. They have 1 1/2 pizzas. If each friend eats 1/4 of a pizza, how many friends can have an equal share?
Simplify your answer
Answer:
6 friends can share the pizza
Step-by-step explanation:
1 1/2 ÷ 1/4 =6
Answer:
Divide 1 1/2 by 1/4. Note that 1 1/2 = 1 2/4 = 6/4. So now we divide 6/4 by 1/4, obtaining 6.
6 friends can enjoy an equal share.

Pilates is a popular set of exercises for the treatment of individuals with lower back pain. The method has six basic principles: centering, concentration, control, precision, flow, and breathing. An article reported on an experiment involving 84 subjects with nonspecific low back pain. The participants were randomly divided into two groups of equal size. The first group received just educational materials, whereas the second group participated in 6 weeks of Pilates exercises. The sample mean level of pain (on a scale from 0 to 10) for the control group at a 6-week follow-up was 5.2 and the sample mean for the treatment group was 3.2; both sample standard deviations were 2.3.
a. Does it appear that true average pain level for the control condition exceeds that for the treatment condition? Carry out a test of hypotheses using a significance level of .01 (the cited article reported statistical significance at this α, and a sample mean difference of 2.1 also suggests practical significance).
b. Does it appear that true average pain level for the control condition exceeds that for the treatment condition by more than 1? Carry out a test of appropriate hypotheses.
Answer:
a) We reject H₀ We find difference between the mean of the two groups
b) we accept H₀ : There is no statistical difference ( in the scale of pain) when the difference in samples means is 1
Step-by-step explanation:
Group 1: Only with educational material
Sample size n₁ = 42
Sample mean x₁ = 3,2
Sample standard deviation s₁ = 2,3
Group 2: With exercises with the treatment of individuals
Sample size n₂ = 42
Sample mean x₂ = 5,2
Sample standard deviation s₂ = 2,3
Test Hypothesis
Null Hypothesis H₀ x₂ - x₁ = 0 or x₁ = x₂
Alternative Hypothesis Hₐ x₂ - x ₁ > 0 or x₂ > x₁
Significance level α = 0,01
Sample sizes are n₁ = n₂ > 30
We use z-test
for α = 0,01 z(c) ≈ 2,32
To calculate z(s)
z(s) = ( x₂ - x₁ ) / √ (2,3)²/42 + (2,3)²/42
z(s) = ( 5,2 - 3,2 )/ √0,2519
z(s) = 2 / 0,5
z(s) = 4
Comparing z(s) and z(c)
z(s) > z(c)
z(s) is in the rejection region. We reject H₀ the true average pain level for the control condition exceeds that for the treatment condition.
b) Does the true average pain level for the control condition exceed that for the treatment condition by more than 1.
In this case
z( s) = x₂ - x₁ / 0,5
z(s) = 1 /0,5
z(s) = 2
Comparing z(s) and z(c) now
z(s) < z(c) 2 < 2,32
And z(s) is in the acceptance region ( for the same significance level) and we should accept H₀ equivalent to say that the two groups statistical have the same mean

What is a straight line?A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.
Here, we have to points (2,4) and, (2,-7)
So, by using the formula of equation of straight line of two-point form, we get,
(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )
=>(y-4)/(x-2)=(-7-4)/(2-2)
=>0 = x-2
=>x =2
Hence, the required equation is, x =2
