Answer:
One of the most basic concepts in statistics is hypothesis testing. Not just in Data Science, Hypothesis testing is important in every field. Want to know how??? Let us take an example. You must have heard about lifebuoy?? Suppose
lifebuoy claims that, it kills 99.9% of germs. So how can they say so? There has to be a testing technique to prove this claim right?? So hypothesis testing uses to prove a claim or any assumptions.

Answer:
Jordan had 18 coins. Two-thirds of the coins were dimes. How many coins were dimes?
Min had 18 quarters. He used 2/3 of the quarters to play arcade games. How many quarters did Min use?
Step-by-step explanation:
2/3 × 18
Checking all options
Sarah mixed 18 ounces of orange juice with 23 ounce of pineapple juice. How many ounces of juice did she have in all?
Ounces of orange juice = 18
Ounces of pineapple juice = 23
Total ounces of juice = 18 + 23
= 41 ounces
A container held 18 ounces of water. Two-thirds of the water leaked out of the container. How many ounces of water were left in the container?
Total water in the container = 18
Water leaked out = 2/3
Ounces of water left = 18 - 2/3(18)
= 18 - 36/3
= 18 - 12
= 6
Jordan had 18 coins. Two-thirds of the coins were dimes. How many coins were dimes?
Total Number of coins = 18
Dimes = 2/3 of 18
Number of dimes = 2/3 × 18
= 36 / 3
= 12
Min had 18 quarters. He used 2/3 of the quarters to play arcade games. How many quarters did Min use?
Total quarters = 18
Quarters used for game = 2/3 × 18
= 2/3 × 18
= 36 / 3
= 12

During the basketball season, Cory made 21 of the 60 baskets she attempted. Krista made 16 out of 40 baskets she attempted. Paul made 17 of the 50 baskets she attempted and Sally 11 of the 55 she attempted. Who had the greatest percentages of baskets made?
Given:
Cory made 21 of the 60 baskets she attempted.
Krista made 16 out of 40 baskets she attempted.
Paul made 17 of the 50 baskets she attempted.
Sally 11 of the 55 she attempted.
To find:
Who had the greatest percentages of baskets made?
Solution:
We know that,
[tex]\text{Percentage of baskets made}=\dfrac{\text{Baskets made}}{\text{Total attempts}}\times 100[/tex]
Using this formula, we get
[tex]\text{Cory's percentage of baskets made}=\dfrac{21}{60}\times 100=35\%[/tex]
[tex]\text{Krista's percentage of baskets made}=\dfrac{16}{40}\times 100=40\%[/tex]
[tex]\text{Paul's percentage of baskets made}=\dfrac{17}{50}\times 100=34\%[/tex]
[tex]\text{Sally's percentage of baskets made}=\dfrac{11}{55}\times 100=20\%[/tex]
From the above percentages 40% is maximum.
Therefore, Krista has greatest percentage of baskets made.

A photo that measure 5 inches in length by 7 inches in width is enlarged to 7.5 inches in length. What is the width?
Answer:
10.5
Step-by-step explanation:
You can use ratios to solve this problem.
The original dimensions of the photo is
5 in. by 7 in.
This can be written as:
5:7
And the next is 7.5:?
Then you can use ratios to solve this.
5:7=
7.5:?
5*1.5=7.5 so you can multiply the other side by the same thing. 7*1.5=10.5
The width is 10.5 inches.

6z = - 12
divide 6 on both sides
z = -2
Answer:
z= -2
Step-by-step explanation:
6z+10=-2

What is the area, in square inches, of the shape below? Express your answer as a fraction in simplest form.
The area of the right-angle triangle will be 1/18 square inches.
What is the area of the right-angle triangle?The area of the right-angle triangle is given as,
A = 1/2 x B x H
Where B is the base and H is the height of the right triangle.
The height of the right-angle triangle is 1/6 inch. And the base length of the right-angle triangle is 2/3 inches. Then the area of the right-angle triangle is given as,
A = (1/2) x (1/6) x (2/3)
A = 2 / 36
A = 1/18 square inches
The area of the right-angle triangle will be 1/18 square inches.

Which of the equations below could be the equation of this parabola? Vertex (0,0) A v=-4 B. Y = 42 C. X=-4x D. x = 4y2

What is a Parabola?A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line
The equation of the parabola is given by
( x - h )² = 4p ( y - k )
y = a ( x - h )² + k
where ( h , k ) is the vertex and ( h , k + p ) is the focus
y is the directrix and y = k – p
The equation of the parabola is also given by the equation
y = ax² + bx + c
where a , b , and c are the three coefficients and the parabola is uniquely identified
Given data ,
Let the parabolic equation be represented as f ( x )
Now , the value of f ( x ) = y
where y = -4x²
The equation y = -4x² represents a parabola that opens downwards (since the coefficient of x² is negative).
The vertex of this parabola is at the origin (0,0), since the coefficient of x is zero. The axis of symmetry is the y-axis, since the parabola is symmetric about this line.
Hence , the equation is y = -4x²

Baxter runs ¾ the length of the backyard every ½ of a minute. Enter the number of lengths of the backyard Baxter runs per minute.
Answer:
Baxter runs 3/2 lengths of the backyard per minute.
Step-by-step explanation:
The question is asking how many times Baxter runs the length of the backyard per minute. We know that he runs 3/4 of the backyard every 1/2 of a minute. This means that he runs 6/4 (simplified to 3/2) per minute.
he heat in the house is set to keep the minimum and maximum temperatures (in degrees Fahrenheit) according to the equation |x – 72.5| = 4. What are the minimum and maximum temperatures in the house? 72.5°F and 76.5°F 68.5°F and 76.5°F 70.5°F and 74.5°F 72.5°F and 74.5°F
Answer:
B. 68.5 & 76.5
Step-by-step explanation:
In order to solve this equation you first need to change your equasion to fit 2 scenarios. So, your 2 equations are x-72.5=4 and x-72.5=-4. From there, you need to solve by adding 72.5 to each equation giving you x=76.5 and x=68.5. 68.5 degrees F is your minimum temperature and 76.5 degrees F is your maximum temperature.

How do you write intervals of increase and decrease?
Answer:
add one per interval
Step-by-step explanation:
an example would be:
+1
+2
+3
or:
+4
+8
+12
Answer:
As part of exploring how functions change, we can identify intervals over which the function is changing in specific ways. We say that a function is increasing on an interval if the function values increase as the input values increase within that interval. Similarly, a function is decreasing on an interval if the function values decrease as the input values increase over that interval. The average rate of change of an increasing function is positive, and the average rate of change of a decreasing function is negative.
The image below shows examples of increasing and decreasing intervals on a function.

If you can purchase 4 books $18 Then how many can you buy with $27?
Answer:
6
Step-by-step explanation:
if you divide 18 by 4 you get 4.5, and if you divide 27 by 4.5 then you get six. hope this is right :/
Answer: 6 books
Work: Okay, The first thing I did was find out how much one book costs. To find that out, I divided $18/4, and the answer is $4.50 per book. Now, we add $4.50 until it's $27. I did that, and it was just 2 more books. (4.50 + 4.50 is $9, so add nine dollars to $18, and that would be $27. Then, divide 27/4.5, and you get 6, meaning the 6 books)
Sorry if this was confusing, but I hope I helped you. :)

solve the system of equations X-Y = -12 and -8x-4y=-12 by combining the equations
Answer:
x = -3
y = 9
Step-by-step explanation:
you can add the equations after multiplying the first one by 8
8x - 8y = -96 added to -8x - 4y = -96
'x' eliminated; -12y = -108; y = 9
Solve for 'x':
x - 9 = -12
x = -12 + 9
x = -3
