Answer: Working or doing homework in bed will reduce one's focus because most people tend to associate their beds with comfort and sleep. Doing such activities in bed can lead to a deviation of the brain to become more lazy and possibly fall asleep.
Disadvantages of studying in bed includes issues related to posture and concentration. Hence, studying in bed often ;
Induces sleep and weariness Inappropriate posture required for studying and assimilation.A bed is primarily meant for sleeping while desks and chairs are made for studying. The difference in the build is due to the purpose of nature of each activity. Studying in an environment meant for sleeping would most likely induce sleep.
Similarly the structure or design of a bed isn't appropriate for studying and may likely affect the rate of assimilation.

Mr Rumpole believes that the mean income of lawyers is now more than $65 thousand per year. Which is the correct set of hypotheses to test this belief?
Answer:
d. Hо:μ ≤ 65,000; H1:μ > 65,000
Step-by-step explanation:
Note: The multiple option to the question is attached as picture below
Null Hypothesis ----> Hо:μ ≤ 65,000
Alternate Hypothesis ----> H1:μ > 65,000
So, option D is correct.
The set of hypotheses that Mr. Rumpole can use to test the stated belief is:
D. H0:μ ≤ 65,000; H1:μ > 65,000
Recall:
We have two types of hypothesis, which are, the null hypothesis and the alternative hypothesis.
The null hypothesis states no statistical relationship or difference exist between two variables. It is denoted by the sign, H0.The alternative hypothesis states there is statistical relationship or difference that exist between two variables. It is denoted by the sign, H1.Therefore, the set of hypotheses that Mr. Rumpole can use to test the stated belief is:
D. H0:μ ≤ 65,000; H1:μ > 65,000

Find the lengths of the missing sides in the pairs of similar triangles
Answer:
x = 4
Step-by-step explanation:
The inner and outer triangles are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{x}{5}[/tex] = [tex]\frac{8}{10}[/tex] ( cross- multiply )
10x = 40 ( divide both sides by 10 )
x = 4

The volume of a cube is given by s3 and the total surface area of a cube is given by 6s2, where s is the side length of the cube.
If the side length of a cube is 5 inches, the volume of the cube is [ put answer here]
cubic inches and its total surface area is [put answer here]
square inches.
Answer:
Volume)
125 inches cubed
Surface area)
150 inches squared
Step-by-step explanation:
So pretty simple and straight forward, nothing hard
So first we know the side length is 5
The volume of a cube formula is s^3
So 5^3=125
Thats one
The second one is 6s^2
So plug it in
6*5^2
Follow orders of operations
5^2=25
25*6=150
So 150 inches squared

Factor the trinomial. Factor out the GCF first.
5h^2k^2 – 15hk^3 – 200k^4
Answer:
The factored form is: [tex]5k^2(h^2 - 3hk - 40k^2)[/tex]
Step-by-step explanation:
The factorization of the trinomial is given by the multiplication of the greatest common factor of each coefficient(numeric, h and k), put it in front, and divide each term by it.
Numeric:
GCF between 5, 15 and 200.
We keep dividing while all factors can be divided by the same number
5 - 15 - 200|5
1 - 3 - 40
No other possible division, so the numeric GCF is 5.
Coefficient h
To the 2, to the 1, and does not appear(to the 0). So the GCF is 0.
Coefficient k
2, 3 and 4. The GCF is 2.
So
[tex]5k^2(\frac{5h^2k^2}{5k^2} - \frac{15hk^3}{5k^2} - \frac{200k^4}{5k^2}) = 5k^2(h^2 - 3hk - 40k^2)[/tex]
The factored form is: [tex]5k^2(h^2 - 3hk - 40k^2)[/tex]

A farm is to be built in the shape of quadrilateral ABCD, as shown below. All four sides are equal.
A rhombus ABCD is shown with diagonal AC equal to 16.8 feet and diagonal BD equal to 11.9 feet
What is the area of the farm?
57.4 square feet
99.96 square feet
114.8 square feet
133.28 square feet
Answer:
99.96 square feet
Step-by-step explanation:
The formula for the area of a rhombus is (pq)/2, where p and q represent the two diagonals:
A=pq/2
=(16.8)(11.9)/2
=199.92/2
=99.96 square feet

In a sample of 528 customers, 237 say they are happy with the service. If you select three customers without replacement for a commercial, what is the probability they will all say they are happy with the service
Answer: 0.0898
Step-by-step explanation:
Probability = [tex]\dfrac{favorable\ outcomes}{Total\ outcomes}[/tex]
Given : Sample size : 528
Number pf customers say they are happy = 237
Probability of getting one happy customer= [tex]\dfrac{237}{528}[/tex]
Probability of getting second happy customer= [tex]\dfrac{236}{527}[/tex] [subtract 1 from both numbers]
Probability of getting third happy customer= [tex]\dfrac{235}{526}[/tex]
If 3 customers are elected without replacement
The probability they will all say they are happy with the service = [tex]\dfrac{237}{528}\times\dfrac{236}{527}\times\dfrac{235}{526}[/tex]
[tex]\approx0.0898[/tex]
Hence, the required probability = 0.0898

A carpenter has a wooden that measures 1/4 meter long. He must cut the board into 6 pieces of equal length. How long in meters should the carpenter cut each piece.
Answer:
1/26 meter
Step-by-step explanation:
You would start by dividing 1/4 by 6. You'd have to multiply 1/4 by the reciprocal of 6 (the reciprocal of 6 would be 1/6). Then you get (1/4) * (1/6), which is equal to 1/24.
Carpenter should cut each piece of wooden board measuring [tex]\frac{1}{24}[/tex] meter.
Let the length of each piece = x meters
Since, the number of pieces (of equal length) of the wooden board = 6
Therefore, total length of wooden board = 6x
It's given in the question that the length of the wooden board is [tex]\frac{1}{4}[/tex] meter.
Therefore, 6x = [tex]\frac{1}{4}[/tex]
[tex]\frac{6x}{6}=\frac{1}{4\times 6}[/tex]
[tex]x=\frac{1}{24}[/tex] meter
Hence, carpenter should cut each piece of wooden board measuring [tex]\frac{1}{24}[/tex] meter.

Amy has 20 necklaces in a jewelry box. The probability of reaching into the jewelry box and pulling out a silver necklace is 0.85. What is the probability that Amy will reach in the jewelry box and pull out a necklace that is not silver?
Answer:
0.15
Step-by-step explanation:
Given
[tex]Necklaces = 20[/tex]
Represent the probability of pulling out silver with p; So:
[tex]p = 0.85[/tex]
Required
Determine the probability of not pulling silver
This question is to test probability complements
And the complement rule of probability states that:
[tex]p + q = 1[/tex]
Where q and p are opposites. In other words:
q = probability of not pulling out silver
Substitute 0.85 for p in [tex]p + q = 1[/tex]
[tex]0.85 + q = 1[/tex]
Make q the subject
[tex]q = 1 - 0.85[/tex]
[tex]q = 0.15[/tex]
Hence, the required probability is 0.15

You deposit $2,500 in a special savings account. The account earns interest at a rate of 3.25% compounded monthly. a. What amount will be in your account at the end of 5 months is no other deposits or withdrawals are made? b. What is the compound interest?
Answer:
1. $2906.25
2. $406.25
Step-by-step explanation:
2500+ (3.25% of 2500) (5)
2500+ (81.25) (5)
2500+ $406.25
=2906.25
3.25% of 2500
=406.25
The required solution,
(a) Amount in the account after 5 months will be $2,933.53.
(b) Compound interest = $433.53.
Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
Amount = principal[1 + r/n]ⁿᵃ
Principal = P rate= r Time =a , n = compounding frequency
Amount = 500[1 + 0.0325/12]⁵
Amount = $2,933.53
Compound interest = Amount - principal
= 2933.53 - 2500
= $433.53
Thus, the required solution,
(a) Amount in the account after 5 months will be $2,933.53.
(b) Compound interest = $433.53.
