At the farmers' market, Ken bought 7/10 of a pound of string beans and 1/2 of a pound of
lima beans. How many more pounds of string beans did Ken purchase?
Answer:6/8
Step-by-step explanation:
Answer:
Ken bought 2/10 of a pond more of string beans then lima beans.
Step-by-step explanation:
1/2 = 5/10
7/10 - 5/10 = 2/10
2/10 = 1/5 if you need a more simplified answer.

Answer:

The standard error of the sampling distribution is 0.014. The closest option to 0.014 among the answer choices is C. 0.045, but it is not a match. None of the provided answer choices matches the calculated value exactly.
To find the standard error of the sampling distribution, we can use the formula:
[tex]Standard Error = \sqrt{[(sample proportion * (1 - sample proportion)) / sample size]}[/tex]
Given a sample size of 120 and a sample proportion of 0.4, we can calculate the standard error as follows:
[tex]Standard Error = \sqrt{[(0.4 * (1 - 0.4)) / 120]}\\Standard Error = \sqrt{[(0.4 * 0.6) / 120]}\\Standard Error = \sqrt{[0.024 / 120]}\\Standard Error = \sqrt{0.0002}\\Standard Error \approx 0.014[/tex]
Rounded to three decimal places, the standard error is approximately 0.014.

if (x-y)=15 what is the value of x^2 -2xy+y^2
Answer:
=225
Step-by-step explanation:
The value of x² - 2xy + y² would be; 225
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
we are given that (x-y)=15
The identity (x + y)² - (x - y)² = 4xy.
(x + y)²= (x² + 2xy + y²)
we have been asked to find x² - 2xy + y²
x² - 2xy + y² = (x - y)²
x² - 2xy + y² = 15²
x² - 2xy + y² = 225

Step-by-step explanation:
how do i solve 3x-8x=-40
Answer:
The answer is 8 below is how you do it.
Step-by-step explanation:
first combine like terms 3x-8x
then you will have 5x
then do 40/5 and you will get x=8
Ok so to solve for x you need to isolate the variable. Usually, when solving an equation the first step would be to get all of the variables of x on the same side but this equation is already set up that way. Since 3x and 8x are both of the variable x you can simply subtract them and you would be left with:
-5x=-40
Now what you want to do is completely isolate x to get it by itself in which you would divide both sides by -5. Remember *When solving an equation you must do the same math to both sides.
-5x/-5=-40/-5
x=8
So the answer would then be 8. Also remember you can always check to see if your equation is correct by plugging your answer into the original equation
3(8) - 8(8) = -40
24 - 64 = -40
-40 = -40

PLEASE HELP ASAP! WILL GIVE BRAINLIEST! The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part.
Answer:
Solution:- In the given figure
Side of square= 10 cm
area of square = side x side m= 10 x 10 = 100 sq cm
Now , diameter of semi circle AOD = 2r = 10cm
⇒ radius of semi circle AOD = 5 cm
∴ area of AOD =
similarly Area of semicircle BOC =
Area of white portion in figure 1 = area of square - [ area of semicircle BOD + area of semicircle AOD]
=
Total area of white portion in the given figure=
∴Area of Shaded portion = area of square - area of total white portion
=
So the area of shaded portion is
Now perimeter of AD(which is a semicircle) = (as perimeter of semicircle=πr)
So the perimeter of shaded region = 4×perimeter of AD=4×15.7=62.8cm

Use the rule "divide by 3" to continue the pattern. Then write the four terms of a different pattern that follows the same rule
Answer:
[tex](a)[/tex]
[tex]Pattern: 2187, 729, 243, 81, 27, 9,3, 1[/tex]
[tex](b)[/tex]
[tex]Pattern = 972,324,108,36[/tex]
Step-by-step explanation:
Given [Missing from the question]
[tex]Pattern: 2187, 729, 243, 81[/tex]
Solving (a): Continue the pattern using the divide by 3 rule
To do this, we simply divide the last term by 3, to get the next term.
So, we have:
[tex]81/3 = 27[/tex]
[tex]27/3 = 9[/tex]
[tex]9/3 = 3[/tex]
[tex]3/3 = 1[/tex]
So, the pattern is:
[tex]Pattern: 2187, 729, 243, 81, 27, 9,3, 1[/tex]
Solving (b): 4 terms of a different pattern using the same rule.
Let the first term be: 972
So, the next three terms is:
[tex]972/3 =324[/tex]
[tex]324/3 = 108[/tex]
[tex]108/3 =36[/tex]
So, the pattern is:
[tex]Pattern = 972,324,108,36[/tex]
The area of a rectangle is 38.5 square inches. The base of the rectangle is 4 inches. What is the height of rectangle?
Pls help me on this one. PLSSS :(
Answer:
The answer is 9.625
Step-by-step explanation:
So what you have is the area and the base of the rectangle. To find the height, just divide 4 into 38.5
38.5 / 4 = 9.625
To double check just multiple 9.625 by 4
9.625 x 4 = 38.5

Emmy baked 18 cookies with 3 scoops of flour. With 4 scoops of flour, how many cookies can Emmy bake? Assume the relationship is directly proportional.
Step-by-step explanation:
For 3 scoops = 18 cookies
Lets use the unitary method,
So for 1 scoop, how many cookies?
So, 18 /3 = 6
So, 1 scoop = 6 cookies
So for 4 scoops we will multiply by 6 (as 1 scoop = 6 cookies)
So, 4 x 6 = 24
So, 24 cookies can be made if we add 4 scoops of flour
4 scoops = 24 cookies

Students at a middle school are divided into 6th, 7th, and 8th grades. A random sample of 15 students from each grade is chosen.
Which sampling method best describes this scenario?
A) simple random sample
B) stratified random sample
C) systematic random sample
D) voluntary response sample
Answer:
B. Stratified random sample is the correct answer
The best sampling method that describes the scenario where students from each grade (6th, 7th, and 8th) are randomly chosen in a sample of 15 students from each grade is B) stratified random sample.
In a stratified random sample, the population is divided into distinct groups or strata based on certain characteristics, and then a random sample is taken from each stratum. In this case, the distinct groups are the different grade levels (6th, 7th, and 8th grades). By randomly selecting 15 students from each grade, we ensure representation from each grade level in the sample.
This method allows for a more accurate representation of each grade level within the sample and can provide valuable insights into the characteristics and experiences of students in each grade.
