Answer: False
Step-by-step explanation:
All the 100 students engaged in the experiment were picked on the basis that all the students of the university have a chance of being selected. The selected participants must have represented the whole university well.
So, having a 95% confidence interval that the experiment might have atmost 5% error prone is statistically enough and not too wide to give an accurate estimate.

Grupo de opciones de respuesta
26 miles
32 miles
28 miles
31 miles
please help me!!!!!!!!!
Answer:
28 miles

when you multiply all answer choices by 42 cents, 28 miles reaches the number 11.76
Answer:
28 miles
Step-by-step explanation:
19.76- 8= 11.76
11.76÷ .42= 28
28 miles
Can someone please explain the Pythagorean theorem to me?
Answer:
Pythagoras theorem is is a mathematical law that states that the sum of squares of the lengths of the two short sides of the right triangle is equal to the square of the length of the hypotenuse.
Step-by-step explanation:
The hypotenuse is the side opposite to the right angle and so the equation for finding the hypotenuse would be:
a^2+^b^2=c^2

what is a communitative property
Answer:
In math, a binary operation is commutative if changing the order of the operands does not change the result. It is a fundamental property of many binary operations, and many mathematical proofs depend on it.
Step-by-step explanation:
Have a nice day!, and subscribe to my animations Y0UTUBE channel! Here is a sneak peek at some of my content!
Channel name: Let Me Explain Studios
Step-by-step explanation:
The communitative property is a math rule that says that the order in which we multiply numbers does not change the product.

Please help I’m not good with this at all!!
how do we compare the absolute values of -99 and 1? *
Answer:
The first one
Step-by-step explanation:
The absolute value of a negative number is the same number but positive if that makes sense. ( ex absolute value of -5 is 5 )
The absolute value of a positive number is literally that number ( ex. absolute value of 6 is 6 )
Thus, the absolute value of 1 is 1 and the absolute value of -99 is 99
99 is greater than 1 which means that the absolute value of -99 is greater than the absolute value of 1
Thus, the answer is the first one

True or false? The graph represents a function. 5. -5 5 2.5 O A. True O B. False
Answer:
True
Step-by-step explanation:
In functions, each x value has its own corresponding y value, this meaning that the x value cannot repeat, and if it does it is not considered a function
Looking at the graph, no x value repeat, thus the graph represents a function

3.15 Linear Equations and Inequalities (SHOW YOUR WORK)
1.) Use the linear graph to answer the question.
A.) Identify the quadrant in which each point lies.
Point A:_____
Point B:_____
Answer:
A- Quadrant one.
B- Quadrant three.
Step-by-step explanation:
So, the quadrants go counter-clockwise, starting at the top right which is Quadrant one. Therefore, A is in one. Using that information, we can assume that B is in Quadrant three.
PLEASE HELP, THIS IS MY LAST QUESTION FOR THE YEAR SO I CAN PASS ALGEBRA (BRAINLIEST IF ANSWERED WITHIN 30 MINS AND CORRECT)
An expression is shown below:
f(x) = 2x2 − 3x − 5
Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part B: Is the vertex of the graph of f(x) going to be a maximum or minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answer:
x intercepts: (-1,0) and (2.5,0)
It will be a minimum because the coeficcent for the degree is positive. The coordinates of the vertex are: (.75,-6.125)
To graph this I would first draw points on the vertex (.75,-6.125) and the x intercepts (-1,0) and (2.5,0). I would then simply just sketch a parabola that met all those points.

What is the missing length?
Answer:
16
Step-by-step explanation:
The area of a triangle is
A =1/2 bh where b is the base length and h is the height
Substitute the values in
69.6 = 1/2 ( 8.7) * p
69.6 = 4.35p
Divide each side by 4.35
69.6/4.35 = p
16 = p
The formula for the area of a triangle is: A = 1/2 * base * height.
Using this formula, let's plug in what we know.
69.6 = 1/2 * 8.7 * height
Next, we'll go ahead and get rid of that 1/2 by multiplying everything by its reciprocal, 2.
139.2 = 8.7 * height
Then, all that's left is to divide both sides by 8.7.
Height = 16 yards
Hope this helps!! :)

Ms. Madero sells tables. She charges $26 per square foot of the tabletop and charges a fixed fee of $75. Which equation could be used to find the area
(x), in square feet, of the tabletop of a table that Ms. Madero sells for $244?
O 26x + 75 = 244
O 26x = 75 +244
O 75x + 26 = 244
O 75x = 26 +244

The table contains some points on the graph of an exponential function.
Based on the table, which function represents the same relationship?
A. Y = 10(4)x B. y = 10(2)x C. y = 40(10)x D. y = 2(40)x
Answer:
B. y = 10(2)^x
Step-by-step explanation:
y = ab^x
to find "b" divide the function at x = 3 by the function at x = 2
80 = ab^3
——————
40 = ab^2
This results in
2 = b
to find "a" plug pickany value of x
using x = 2
40 = a(2²)
40 = a(4)
a = 10
With a = 10 and b = 2 the exponential function y = ab^x is
y = 10(2)^x
Forty nine minus twenty five b squared in factored form
