What are statistics?Statistics is a mathematical tool defined as the study of collecting data, analysis, understanding, representation, and organization. Statistics is described as the procedure of collecting data, classifying it, displaying that in a way that makes it easy to understand, and analyzing it even further.
It is given that:
A fast-food chain claims one small order of its tater tots weighs 90 grams.
She weighs the next 14 random orders of tater tots before she eats them.
The sample mean X = 89.3 grams
The standard deviation SD = 3.71 grams
Z = (u - X)/sd
Z = (90 - 89.3)/3.71
Z = 0.18
Thus, Ava doesn’t have sufficient evidence to reject the fast-food chain's claim that option (C) is correct.

What is the inverse of the function below?
fx) = x - 4
O A. f-1(x) = x- 4
O B. f- (x) =-X+4
O c. f-1(x) = x+4
O D. f-1(x) = -x- 4
The inverse of the function is f ( x )⁻¹ = x + 4
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x - 4 be equation (1)
On simplifying , we get
The inverse of the function is given by replacing x with y
So , the value of the function is
y = x - 4
x = y + 4
On interchanging , we get
f ( x )⁻¹ = x + 4
Hence , the inverse is f ( x )⁻¹ = x + 4

a jewelry maker uses 4/5 yards of wire to make 3 necklaces. She uses the same length of wire for each necklace. What length of wire will she use to make 5 of the same necklaces.
Answer:
[tex]\frac{4}{3} \text \ yards\ of\ wire[/tex]
Step-by-step explanation:
She uses 4/5 yards of wire to make 3 necklaces
Then
In Oder to make 1 necklace she use :
[tex]\frac{\left( \frac{4}{5} \right) }{3} =\frac{\frac{4}{5} }{\frac{3}{1} } =\frac{4}{5} \times \frac{1}{3} = \frac{4}{15}\ \ \small\text yards\ of \ wire[/tex]
Now to make to make 5 of the same necklaces she needs :
[tex]\frac{4}{15} \times 5=\frac{4}{15} \times \frac{5}{1} =\frac{20}{15}= \frac{4}{3} \ \ \ \text \ yards\ of\ wire[/tex]

Answer:
4^4 =16
Step-by-step explanation:
4^4 = 4 · 4
they are both the same thing
4 + 4+4+4 = 16
Change the subject of the equation v = u + at to a.
In order to make a the subject of this equation , we need to get a by itself .
The current equation is :
v = u + at
Subtract u on both sides :
v-u=at
Now, divide by t on both sides :
v-u/t=a
So the formula looks like ↓[tex]\boxed{\\\begin{minipage}{3cm}Equation \\ a=$\displaystyle\frac{v-u}{t} $ \\ \end{minipage}}[/tex]

Find all real numbers x such that 3x - 4 < 5 and -8x - 19 < 21
Answer:
the numbers are -5 and 3
Step-by-step explanation:
First of all, the question is asking you to find the values of x from the given inequalities.
-8x -19<21 and 3x - 4 < 5
group all liked terms, in other words, make x and its coefficient stand alone.
-8x < 21 + 19 and 3x < 5 + 4
-19 became +19 because it crossed the sign <, also -4 became +4 because it crossed the sign <.
so we get
-8x < 40 and 3x < 9
we divide each "x" by its coefficient
[tex] \frac{ - 8x}{ - 8} < \frac{40}{ - 8} \: and \: \frac{3x}{3} < \frac{9}{3} [/tex]
then we get
x < -5 and x < 3
but x is positive so it's greater than -5 so we get
x > -5 and x < 3
Find the area of the shape below:
NOTE: The figure is NOT drawn to scale
Answer:
Find the rectangle's area on the left hand side, using the formula:
A = l x w
Where 'l' represents the length and 'w' stands for the width.
Plug in what you know:-
A = l x w
A = 15 x 5
A = 75 square units is the area of the left rectangle.
Now let's find the rectangle's area on the right hand side, using the formula:
A = l x w
Where 'l' represents the length and 'w' stands for the width.
A = l x w
A = 15 x 4
A = 60 square units is the area of the right rectangle.
Now find the middle small horizontal rectangle's area, using the formula:
A = l x w
Where 'l' represents the length and 'w' stands for the width.
But, let's figure out the length first.
We know that from the left rectangle, the two side lengths beside the unknown length of the middle rectangle area 5 and 7.
The unknown length plus those two lengths (5&7) will have to equal 15 since that is the total length, so;
15 - (5 + 7) = x
15 - 12 = x
3 = x, so the unknown length of the middle rectangle is 3.
Plug in what you know into the formula:
A = l x w
A = 3 x 7
A = 21 square units is the area of the middle rectangle.
Now add up all the areas together:
75 + 60 + 21
= 156 square units is the area of the shape.
What is the area of the figure?
A figure can be broken into a rectangle and triangle. The rectangle has a base of 5 feet and height of one-third feet. The triangle has a base of 3 and two-thirds feet and height of 2 feet.
5One-third ft2
6 and two-thirds ft2
7 ft2
9 ft2
Answer:
Given a figure that is broken into a rectangle and triangle.
The dimensions of the rectangle are:
Base : 5 ft
Height : 1/3 ft
The dimensions of the triangle are :
Base : 3 upon 2/3 ft
Height : 2 ft
The area of the figure calculated below :-
Area of rectangle + Area of triangle
Area of rectangle + Area of triangleLB + 1/2BH
(5×1/3) + (1/3+3upon2/3×2)
The result is simplified below :-
5/3+11/3
5+11/3
16/3 ft
51/3 ft square.
The area of the figure is 5 and one third square feet.
Answer:
5 1/3

To make lemonade, Carlos used 5 times more water than lemon juice. He used 3 pints of lemon juice. After making the lemonade, he poured it equally into 4 jugs. How many cups of lemonade are in each jug?
Answer:
11 Cups
Step-by-step explanation:
Carlos used 3 pints of lemon juice and 5 times more water than lemon juice. So, he uses 3 x 5 = 15 pints of water for the lemonade. The amount of lemonade is 15 + 3 = 18 pints. Now he pours it equally into 4 jugs which makes it 18 ÷ 4 = 4.5 pints in each jug. Now 1 pint fills 2.4 cups which means 4.5 pints will fill 4.5 x 2.4 = 10.8 cups which will apprroximately be 11 cups.
