Answer:
Scientist B
Step-by-step explanation:
1 kg = 2.2 lbs
1L = 2.11 pints
So let's convert Scientist B's data.
3.0lbs salt = 3.0/2.2 = 1.36kg
6 pints water = 6/2.11 = 2.84L water
Scientist A
1kg salt
3.0L water
We now figure out the concentration of salt in water.
Scientist A Scientist B
1kg/3.0L = .33kg/L 1.36kg/2.84L = .48kg/L
So scientist B had a more concentrated solution.

Lila owes $33,000 in student loans. If her loan is to be repaid in 6.5 years and the interest rate is charged 6.75 percent, how much will she pay all together?
Answers
Answer: $ 47,478.75
Step-by-step explanation:
Formula: Interest = Principal x rate x time.
As per given: Principal amount = $33,000
Rate of interest = 6.75 percent = 0.0675 [To convert in decimal divide it by 100]
Time = 6.5 years
∴ Interest = (33000)× (0.0675)×(6.5)
=$ 14,478.75
Total amount need to pay = Principal+ Interest
= $ ( 33,000 +14,478.75)
= $ 47,478.75
∴ She will pay all together = $ 47,478.75

How long does it take a car travelling at 60 m..p.h to go 5 miles?
Answers
Answer:5 minutes
Step-by-step explanation:
Answer:
We are traveling at a speed S = 60 m/h
The distance we are traveling is D = 5m
We know that:
Speed (S) = distance (D)/ Time (T)
60 = 5 / T
==> T = 5/60 = 1/12 hour
==> T = 1/12 * 60 minutes = 5 minutes.
Then, the time needed to travel 5 miles at a 60m/h speed is 5 minutes.
Richard and his friend Julie collect coins as a hobby. Richard has 8 more coins than Julie. If they have 28 altogether how many coins did Julie have?
Answers
Answer:
Julie had 10 coins
Step-by-step explanation:
Since there are 28 coins and Richard has 8 more coins than Julie
You can subtract 8 from 28 and get 20
then you would divide 20 by 2 since there are two people( Richard and Julie) Which would give you 10
Since Richard has 8 more coins and each of them have ten you would add 8 to the 10 and you would get 18
Meaning that Richard had 18 coins and Julie had 10 coins

Some descriptive statistics for a Set of test scores are shown above for this test a certain student has a standardized score of z=-1.2 what score did the student receive on the test
Answers
Complete Question
The complete question is shown on the first uploaded image
Answer:
The score of the student is x = 779.42
Step-by-step explanation:
Generally we can mathematically represent the z-score as
[tex]z = \frac{x - Mean}{ stDev}[/tex]
Here x is the score of the student
substituting 1045.7 for the Mean, 221.9 for the stDev and -1.2 for z we have
[tex]-1.2 = \frac{x - 1045.7 }{ 221.9}[/tex]
=> [tex]-266.28 = x -1045.7[/tex]
=> x = -266.28 + 1045.7
=> x = 779.42
The student scored 779.42 for him to have a z score of - 1.2;
z score is used to determine by how many standard deviations the raw score is above or below the mean.
The z score is given by:
[tex]z=\frac{x-\mu}{\sigma/ } \\\\where\ x\ is\ raw\ score,\mu\ is\ mean, \sigma\ is\ standard\ deviation[/tex]
Given that μ = 1045.7, σ = 221.9 Hence for z = -1.2:
[tex]-1.2=\frac{x-1045.7}{221.9} \\\\x=779.42[/tex]
The student scored 779.42 for him to have a z score of - 1.2;

which shows two products that result in negative values
Answers
Answer:
(2.4)(-1.8) and (0.6)(-0.4)
Step-by-step explanation:
The product of two negative numbers = a positive number. (negative × negative = positive).
Product of two positive numbers = a positive number. (Positive × positive = positive)
Product of a negative number and a positive number = a negative number. (Negative × positive = negative).
Therefore, the answer choice that shows two products that both will result in negative values would be the answer choice that has a negative number multiplying a positive number.
Option 3 has two products in which each has a negative and positive number. That is (2.4)(-1.8) = a negative value, and
(0.6)(-0.4) = a negative value.
Therefore, the answer is Option 3: (2.4)(-1.8) and (0.6)(-0.4)

In 1970, 59% of college freshmen thought that capital punishment should be abolished; in 2005, the percentage was 35%. The percentages are based on two independent simple random samples, each of size 1,000. Compute a 95% confidence interval for the difference in the percentages.
Answers
Answer:
The 95% confidence interval for the difference in the percentages = [19.75, 28.25]
Step-by-step explanation:
The formula for confidence interval for difference in percentages =
p1 - p2 ± z x √[p1(100 - p1)/n1 + p2(100 - p2)/n2)
From the above question:
p1 = 59%
n1 = 1000
p2 = 35%
n2 = 1000
z = z score of the 95% confidence interval = 1.96
Confidence interval = p1 - p2 ± z x √[p1(100 - p1)/n1 + p2(100 - p2)/n2)
= 59 - 35 ± 1.96 × √[59(100 - 59)/1000] + [35(100 - 35)/1000]
= 24 ± 1.96 × √ [59 × 41/1000] + [35 × 65/1000]
= 24 ± 1.96 × √[2419/1000 + 2275/1000]
= 24 ± 1.96 × √2.419 + 2.275
= 24 ± 1.96 × √(4.694)
= 24 ± 1.96 × 2.1665641001
= 24 ± 4.2464656363
Confidence Interval = 24 ± 4.2464656363
24 - 4.2464656363 = 19.753534364
Approximately = 19.75
24 + 4.2464656363 = 28.2464656363
Approximately = 28.25
Therefore, the 95% confidence interval for the difference in the percentages = [19.75, 28.25]

Hey there!
ANSWER: [tex]p=25[/tex]EXPLANATION:[tex]0.4p-5=0.08p+3[/tex]
To solve this inequality, we will need to subtract 0.08p from both sides of the inequality.
[tex]0.4p-5-0.08p=0.08p+3-0.08p\\0.32p-5=3[/tex]
Now we have to add both sides by 5.
[tex]0.32p-5+5=3+5\\0.32p=8[/tex]
In our last step, we will have to divide both sides by 0.32.
[tex]\frac{0.32p}{0.32} =\frac{8}{0.32}\\25\\\text{25 is your answer.}[/tex]

Answers
Set A is not a subset of which set of numbers rational numbers option (A) Rational numbers are correct.
What is set?A set is a collection of clearly - defined unique items. The term "well-defined" applies to a property that makes it simple to establish whether an entity actually belongs to a set. The term 'unique' denotes that all the objects in a set must be different.
It is given that set A:
A ={0, 3, 8}
A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
As we know,
The set of an Integers number = {-∞, ∞}
The set of a whole number = {0, ∞}
The set of a counting number = {-∞, ∞}; all are integer values
Set A is the subset of all the sets shown above.
Thus, set A is not a subset of which set of numbers rational numbers option (A) Rational numbers are correct.

9. You are the sales manager for Solar Panel Company. You receive a commission
based on the total sales of all the salespeople you manage. Your commission is
2 percent of the first $80,000 of sales, 4 percent of the next $80,000, and 5 percent
of all sales over $160,000. What is your commission for a month in which your
salespeople sold $242,100 in solar panels?
Answers
Answer: $9705.
Step-by-step explanation:
2 % of first $80,000 sold
= 2/100 * $80,000
= 2 * $800
= $1600
4% of next $80,000
= 4/100 * $80,000
= 4 * $800
= $3,200
if total sales was $242,100. for this Month, the sales person commission would be
= $1600 + 5/100 * 162,100
= $1600 + 5 * $1621
= $1600 + $8105
= $9705.
