Step-by-step explanation:
Katarina tosses a thumbtack on the ground 20 times to see if it lands on its side or if it lands with the point
facing up (there are no other possible outcomes). Let S = the number of times it lands on its side.
Is S a binomial variable? Why or why not?
Answer:
This situation satisfies each of the conditions for a binomial variable, so
S
SS has a binomial distribution.
Step-by-step explanation:
True. Each trial has two outcomes (lands on side or doesn't), results of each trial are independent, there is a fixed number of trials (
20
2020), and the probability of success is the same for each trial.

Answer:
Second Choice
Step-by-step explanation:
Using Pythagorean theorem:
17.3²=4.4²+13.1²
299.29=19.36+171.61
299.29≠190.97

Dan used 942 units of electricity from July to October
The meter reading in July was 32 347 units.
a)
Work out the meter reading in October.
b)
Each unit costs 14p.
How much do 942 units cost?
Answer:
13,188
Step-by-step explanation:
14 × 942
That will give you 13,188
Answer:
a) 33289
b) £131.88
Step-by-step explanation:
→ To find the meter reading add the July reading to the units used
32347 + 942 = 33289
→ Multiply the unit price by the units used
0.14 × 942 = 131.88
X= [3 -5] Y= [6 7]
[-4 2]. [-4 -3] calculate X+Y
Answer: [tex]X+Y=\begin{pmatrix}9&2\\ -8&-1\end{pmatrix}[/tex]
Step-by-step explanation:
Given: [tex]X=\begin{pmatrix}3&-5\\ -4&2\end{pmatrix},\ \ Y=\begin{pmatrix}6&7\\ -4&-3\end{pmatrix}[/tex]
To calculate: [tex]X+Y[/tex]
Consider [tex]X+Y= \begin{pmatrix}3&-5\\ -4&2\end{pmatrix}+\begin{pmatrix}6&7\\ -4&-3\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}3+6&\left(-5\right)+7\\ \left(-4\right)+\left(-4\right)&2+\left(-3\right)\end{pmatrix}\\\\=\begin{pmatrix}9&2\\ -8&-1\end{pmatrix}[/tex][[tex]\mathrm{Add\:the\:corresponding\: elements\: and\: simplify}[/tex]]
Hence, [tex]X+Y=\begin{pmatrix}9&2\\ -8&-1\end{pmatrix}[/tex]

thus that means 0 + 1 = 1
Answer:
(x+3)²=(√x+3)²
x²+6x+9=x+3
x²+5x+6=0

Describe how the graphs of square root and cube root functions are similar and how they are different.
Explain why they are different!!!
Answer:
Just as the square root is a number that, when squared, gives the radicand, the cube root is a number that, when cubed, gives the radicand. Cubing a number is the same as taking it to the third power: 23 is 2 cubed, so the cube root of 23 is 2.
Step-by-step explanation:

The graphs of Square root function only continues in one direction forever whereas the cube root function continues in two directions forever.
What is Square root function?"The principal square root function [tex]f(x) = \sqrt{x}[/tex] (usually just referred to as the "square root function") is a function that maps the set of non negative real numbers onto itself."
What is Cube root function?"The cube root function [tex]f(x) = \sqrt[3]{x}[/tex] is a continuous function, with no start or end point. Its domain is all real numbers."
The similarities in the graphs of square root function and cube root function are positive function (0,∞), x-intercept: intersects x-axis at (0, 0)
y-intercept: intersects y-axis at (0, 0).
The square root function only utilizes the positive square root. If both positive and negative square root values were used, it would not be a function. The cube root function can process both positive and negative values.
Hence, the graphs of Square root function only continues in one direction forever whereas the cube root function continues in two directions forever.

#CMIIWThe area of a rectangle is 27m and the length of the rectangle is 3m less then twice the width. Find the dimensions of the rectangle
Answer:
w = 4 1/2
l = 6
Step-by-step explanation:
w = width
2w-3 = length
A = lw
27 = w(2w-3)
27 = 2w² - 3w
subtract 27 from each side:
2w² - 3w - 27 = 0
factor:
(2w-9)(w+3) = 0
solve each for 'w':
w = 9/2
w = -3 (This answer can be discounted because a length cannot be negative)
width = 9/2
length = 2(9/2) - 3 which is 6

A bookstore wants to determine how many books the people in the surrounding neighborhood read per month on average. they survey each customer who enters their store for one week. identify any bias in this method. if appropriate, suggest a method more likely to produce a random sample.
Internet poll: To find out more about the locals, the bookshop may hold a equation poll online. This could lessen bias by allowing for the collection of a bigger and more varied sample.
What is equation?A mathematical equation links two statements and utilises the equals sign (=) to indicate equality. In algebra, an equation is a mathematical assertion that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a gap. A mathematical formula may be used to determine how the two sentences on either side of a letter relate to one another. The logo and the particular piece of software are usually identical. like, for instance, 2x - 4 = 2.
This technique might be biased in a number of ways:
Self-selection bias: Visitors to the bookshop may be more likely to be readers than those who live in the area as a whole. This can cause the average number of books read per month to be overestimated
The bookshop might try the following to create a more random sample:
Instead of depending on customers who chance to walk into the store, the bookstore may randomly choose a sample of residents from the neighborhood and conduct a poll with them.
Internet poll: To find out more about the locals, the bookshop may hold a poll online. This could lessen bias by allowing for the collection of a bigger and more varied sample.
