Answer:
The weight of the displaced water is the weight of the body
Step-by-step explanation:
In situations like this, the volume of the displaced water is not important.
However, it should be noted that when a body is immersed (fully or partially) in a liquid, the weight of the displaced liquid is equal to the weight of the body immersed in the liquid.
Since the weight of the body is not given, I'll conclude that the displaced water has the same weight as the body floating on the water.

I need to write a proportion to the following problem:
3 folders cost $2.91. What written proportion would help determine the cost of 2 folders?
Answer:
The cost of two folder is $ 1.94
Solution:
Given that 3 folders cost $ 2.91
We have to determine the cost of 2 folder
From given,
Cost of 3 folder = $ 2.91
To find the cost of 1 folder, divide 2.91 by 3
Thus cost of 1 folder is $ 0.97
We are asked to find cost of two folders.
Therefore, multiply cost of 1 folder by 2
Thus cost of two folder is $ 1.94

The rectangle below is enlarged using a scale factor of 1.5. What will be the new length and width of the rectangle?
Answer: length = 4.5 m, width = 3 m
Step-by-step explanation:
When a shape is enlarged using a scale factor, you simply multiply each of the sides by the scale factor.
length = 3 * 1.5 = 4.5 m
width = 2 * 1.5 = 3 m

The list of undergraduate college students obtained from her university is n= 1196
The number of student that are randomly selected is n = 500
The number of e-mail that was returned is k = 107
The proportion that believes that the federal student loan program needs to be completely overhauled is [tex]\^{p} = 0.71[/tex]
Generally the population for this particular study is
All undergraduate college students at the researcher's university ,
this is because they are the total pool of data from which the statistical sample are randomly selected from
Generally the sample for this particular study is
The 107 undergraduate college students who returned the questionnaire
this is because this data provides us with an insight on the perspective of all undergraduate college students at the researcher's university about federal financial aid

A psychologist has designed an index to measure the social perceptiveness of elementary school children. The index is based on ratings of a child's responses to questions about a set of photographs showing different social situations. A random sample of 16 elementary school children was chosen, and their index measurements were recorded. Assume that the index measure in the population is normally distributed. The 95% confidence interval created from this data is (56.29, 65.09). This interval indicates:__________.Choose one or more:a. The average index of elementary school children must be 60.69.b. The standard deviation of the sample is about 10% smaller than the population standard deviation.c. That if we take many samples from this population 95% of them will have a sample mean between 56.29 and 65.09.d. 95% of all elementary school children in this district have indices between 56.29 and 65.09.e. 4.40 is 95% of the true average of the index for all elementary school children.f. We are 95% confident that the average index for all elementary school children is between 56.29 and 65.09.

d. 95% of all elementary school children in this district have indices between 56.29 and 65.09.
e. 4.40 is 95% of the true average of the index for all elementary school children.
f. We are 95% confident that the average index for all elementary school children is between 56.29 and 65.09.
Answer:
The correct option is a and f
Step-by-step explanation:
From the question we are told that
The sample size is n = 16
The 95% confidence interval is (56.29, 65.09)
Generally the sample mean(average index of elementary school children) is mathematically represented as
[tex]\= x = \frac{65.09 + 56.29}{2}[/tex]
=> [tex]\= x = 60.69 [/tex]

A person going to a party was asked to bring 4 different bags of chips. Going to the store, she finds 13 varieties.
How many different selections can she make?
(this is a probability question)
Answer:
Step-by-step explanation:
13!/4(13-4)!
13!/4(9)!
Continue simplifying.
The formula for combinations n!/r!(n-r)! pay attention to class next time
"715" are the different selections she can make.
Given:
Number of different begs,
4Total number of varieties,
13So,
Total number of different selection = ¹³C₄
= [tex]\frac{13!}{4!\times (13-4)!}[/tex]
= [tex]\frac{13!}{(4!\times 9!)}[/tex]
= [tex]\frac{13\times 12\times 11\times 10}{4\times 3\times 2}[/tex]

Janet can make 4/5 of a necklace in 20 minutes. At this rate, how many necklaces, to the nearest tenth of a necklace, can Janet make in 1 hour?
Answer: 4 necklaces
Step-by-step explanation: 4/5 x 5 = 4
hope this helps
Answer:
Janet makes 2.4 necklaces in 1 hour
Step-by-step explanation:
first you need to find how many minutes it takes to make one necklace.
to do this, divide 20 by 4 and multiply by 5.
20/4 = 5
5 * 5 = 25
janet makes one necklace every 25 minutes.
one hour is 60 minutes.
