a gift shop sells walnuts in three fourth pond bags . Ann wants to buy enough to have 4 pounds of walnuts. How many 3/4 pound bags will she need to buy?
Answer: 4 pounds is equal to 16 four-ounce (1/4 pound) increments.
To find the number of 3/4 pound bags Ann needs to buy, we can convert 16 four-ounce increments to three-fourth pound increments:
16 four-ounce increments = 16 x 4 = 64 ounces
64 ounces = 64/16 = 40 three-fourth pound increments
Therefore, Ann will need to buy 40 bags of walnuts, each weighing 3/4 of a pound.

To beat the school long jump record, John must jump an additional 5 1/4 inches
Calculating the additional distance to beat a long jump recordFrom the given question, we are to determine how farther John must jump in order to break the record
From the given information,
"A high school track team's long jump record is 23 ft 1 3/4 in"
and
"John's best long jump is 22 ft 8 1/2 in"
First, we will convert the distances to inches
NOTE: 1 ft = 12 inches
23 ft 1 3/4 in = 276 + 1 3/4 in = 277 3/4 in
22 ft 8 1/2 in = 264 + 8 1/2 in = 272 1/2 in
Now, to determine how farther John must jump, we will subtract the distances
277 3/4 in - 272 1/2 in = 5 1/4 in
Hence, he must jump 5 1/4 in farther

A coach asked her athletes if they enjoy running. Fifty-five percent of the team do not like to run. Of those, 70% enjoy cycling, while 80% of those who enjoy running also enjoy cycling. The tree diagram shows how the athletes are divided into subgroups.
The tree diagram shows athletes branching off into two categories, enjoys running and does not enjoy running. Enjoys running branches off into two sub-categories, enjoys cycling and does not enjoy cycling. Does not enjoy running branches off into two subcategories, enjoys cycling and does not enjoy cycling.
What is the total percentage of the athletes who enjoy cycling?
9%
25.5%
55%
74.5%
Answer:
75%
Step-by-step explanation:
To determine the total percentage of athletes who enjoy cycling, we need to consider the percentages given in the problem.
According to the information provided:
55% of the team does not like to run.
Of those who do not like to run, 70% enjoy cycling.
Of those who enjoy running, 80% also enjoy cycling.
To calculate the total percentage of athletes who enjoy cycling, we need to consider the percentages from both branches of the tree diagram.
Percentage of athletes who do not like to run and enjoy cycling:
= (Percentage of athletes who do not like to run) * (Percentage of those who enjoy cycling within that group)
= 55% * 70% = 38.5%
Percentage of athletes who enjoy running and enjoy cycling:
= (Percentage of athletes who enjoy running) * (Percentage of those who enjoy cycling within that group)
= (100% - 55%) * 80% = 45% * 80% = 36%
Total percentage of athletes who enjoy cycling:
= Percentage of athletes who do not like to run and enjoy cycling + Percentage of athletes who enjoy running and enjoy cycling
= 38.5% + 36% = 74.5%
Therefore, the correct answer is:

The perimeter of Sam's string is 178 inches.
Given information:
Sam has a rectangular shaped window.
Length = 65 inches.
Width = 24 inches.
To find the perimeter:
you can use the formula:
Perimeter = 2 x (Length + Width)
Substituting the values into the formula, we have:
Perimeter = 2 x (65 + 24)
Perimeter = 2 x 89
Perimeter = 178 inches
Therefore, the perimeter of the rectangular window is 178 inches.
So, the perimeter of the rectangular window is 178 inches. This means that if you were to walk along the outline of the window, you would cover a total distance of 178 inches. It's important to note that the perimeter represents the total length of all the sides combined, and it is measured in the same unit (in this case, inches) as the length and width of the window.

El mayor es Novecientos mil cuatrocientos ochenta y nueve , y cuarenta mil dos
El número "Novecientos mil cuatrocientos ochenta y nueve" se representa como 900,489 en notación numérica.
Por otro lado, el número "cuarenta mil dos" se representa como 40,002.
Si estamos buscando determinar cuál de estos dos números es mayor, podemos comparar las cifras en cada posición.
Comenzando desde la izquierda, el primer dígito de 900,489 es 9, mientras que el primer dígito de 40,002 es 4.
Dado que 9 es mayor que 4, podemos concluir que 900,489 es mayor que 40,002.
En general, al comparar números, se debe observar cada posición en orden de mayor a menor importancia.
Esto significa que el primer dígito a la izquierda es el más significativo y tiene más peso en el valor total del número.
Si los dígitos en la posición más significativa son iguales, se debe pasar a la siguiente posición hasta que se encuentre una diferencia.

Determining Whether a Difference Is Statistically

You calculated the standard deviation of the sample mean differences to be 0.69. You also
calculated the sample mean difference to be 1.74. Now you'll determine whether the

To
Options for 2) 3.44, 1.26, 1.38, 3.48

Using the z-distribution, it is found that:
The 95% confidence interval is of -1.38 to 1.38.The value of the sample mean difference is of 1.74, which falls outside the 95% confidence interval.What is the z-distribution confidence interval?The confidence interval is:
\(\overline{x} \pm zs\)
In which:
\(\overline{x}\) is the difference between the population means.s is the standard error.In this problem, we have a 95% confidence level, hence\(\alpha = 0.95\), z is the value of Z that has a p-value of \(\frac{1+0.95}{2} = 0.975\), so the critical value is z = 1.96.
The estimate and the standard error are given by:
\(\overline{x} = 0, s = 0.69\)
Hence the bounds of the interval are given by:
\(\overline{x} - zs = 0 - 1.96(0.69) = -1.38\)
\(\overline{x} + zs = 0 + 1.96(0.69) = 1.38\)
1.74 is outside the interval, hence:
The 95% confidence interval is of -1.38 to 1.38.The value of the sample mean difference is of 1.74, which falls outside the 95% confidence interval.More can be learned about the z-distribution at https://brainly.com/question/25890103

A survey of recent high school graduates regarding literature that they studied during their high school career yielded the following information: 892
read Gone with the Wind, 472 read To Kill A Mockingbird, 582 read Lord of the Flies, 113 read all three, 33 read none, 74 read only Lord of the Flies, 163 read Lord of the Flies and To Kill A Mockingbird, and 193 read To Kill A Mockingbird and Gone with the Wind, but not Lord of the Flies. What percent of the recent graduates read exactly one book? Round your answer to the nearest tenth, if necessary.
13.1% of the recent graduates read exactly one book.
How to represent the dataWe can solve this problem using set theory and the Principle of Inclusion-Exclusion (PIE).
Let's define the following sets:
A = students who read Gone with the WindB = students who read To Kill A MockingbirdC = students who read Lord of the FliesWe want to find the number of students who read exactly one book, which is equivalent to finding the number of students who are in exactly one of the sets A, B, or C.
By PIE, we can find the number of students who read exactly one book as follows:
|A ∪ B ∪ C| = |A| + |B| + |C| - |A ∩ B| - |A ∩ C| - |B ∩ C| + |A ∩ B ∩ C|
We already have the values of |A|, |B|, and |C| from the given information:
|A| = 892|B| = 472|C| = 582To find |A ∩ B|, we can use the given information that 193 students read both To Kill A Mockingbird and Gone with the Wind, but not Lord of the Flies:
|A ∩ B| = 193
Similarly, to find |A ∩ C| and |B ∩ C|, we can use the given information that 163 students read Lord of the Flies and To Kill A Mockingbird, and 74 students read only Lord of the Flies:
|A ∩ C| = 0 (since the students who read both A and C would have read all three books, but only 113 students are known to have read all three books)
|B ∩ C| = 163
Finally, we have the value of |A ∩ B ∩ C| from the given information:
|A ∩ B ∩ C| = 113
Putting all this information together, we have:
|A ∪ B ∪ C| = 892 + 472 + 582 - 193 - 0 - 163 + 113 = 1848
Thus, the number of students who read exactly one book is:
1848 - (|A| + |B| + |C| - |A ∩ B| - |A ∩ C| - |B ∩ C| + |A ∩ B ∩ C|) = 1848 - (892 + 472 + 582) + 193 + 0 + 163 - 113 = 1848 - 2046 + 243 = 243
Finally, the percentage of students who read exactly one book is:
(243 / 1848) * 100 = 13.1% (rounded to the nearest tenth)
So, 13.1% of the recent graduates read exactly one book.
