Answer:
Mean = 32.25
median = 31.5
Answer:
Median = 31.5
Mean = 32.25
Step-by-step explanation:
Number of data = 8
Ascending order:
30 , 30 , 31 , 31 , 32 , 33 , 35, 36
Median = Average of 4th and 5th term
= (31 + 32) / 2
= 63/2
= 31.5
Mean = Sum of all the observations /number of observations
= (31 + 32 + 36 +31 + 30 + 35 + 33 +30) / 8
= 258/8
= 32.25

Dan and Paul share some money in the ratio 9:5.
Dan decides this is unfair so he gives Paul £32 of his share to make the ratio 1:1.
How much did Paul originally have?
Answer:
Paul had £40 originally.
Step-by-step explanation:
Given
Let d be the money Dan has and p be the money Paul has
Then according to the given situation,
[tex]\frac{d}{p} = \frac{9}{5}\\d = \frac{9p}{5}\ \ \ Equation\ 1[/tex]
Now from the statement, "Dan decides this is unfair so he gives Paul £32 of his share to make the ratio 1:1"
[tex]\frac{d-32}{p} = 1[/tex] Eqn 2
From 2
[tex]d - 32 = p\\[/tex]
Putting d = 9p/5
[tex]\frac{9p}{5} - 32 = p\\9p - 160 = 5p\\9p-5p = 160\\4p = 160\\\frac{4p}{4} = \frac{160}{4}\\p = 40[/tex]
Checking
[tex]d = \frac{9(40)}{5} = \frac{360}{5} = 72\\\frac{d}{p} = \frac{72}{40} = \frac{9}{5}[/tex]
Hence,
Paul had £40 originally.

Step-by-step explanation:
if you paid 7.50 for 6 feet of rope we can figure out how much each foot of rope is by example 750 divided by 6 which equals 1.25 .
Answer:
$62.50
Step-by-step explanation:
Proportions:
$7.50 ⇔ 6ft
$R ⇔ 50ft
R = 7.5*50/6
R = $62.5

Answer:
40 termsStep-by-step explanation:
Sum of n terms formula:
Sn = 1/2n(a1 + an)Solving for n
3480 = 1/2n(9 + 165)3480 = 87nn = 3480/87n = 40Answer:

Answer:
Students use linear, quadratic, and exponential functions to model data from tables and choose the regression
most appropriate to a given context. They use the correlation coefficient to determine the accuracy of a
regression model and then interpret the function in context. They then make predictions based on their model
and use an appropriate level of precision for reporting results and solutions.
Lesson 7 focuses on data sets that cannot be modeled accurately, and students are asked
to articulate why. Students use skills learned in Lesson 14 of Module 2 (where they used
calculators to write linear regressions) and apply similar techniques for data sets that are
better suited to modeling with quadratic or exponential regressions. Students use that
same technique to find linear regressions and use their graphing calculators to examine
the correlation coefficient and to find quadratic and exponential regressions. They
compare correlation coefficients to determine which model is best for the data.
Ultimately, students choose the regression model (linear, quadratic, or exponential) most
appropriate to a given data set and then write, verify, and interpret these models in
context. Students need a graphing calculator to complete this lesson. Graphing calculator
instructions are provided, but steps may vary slightly depending on the model of the
graphing calculator.
Refer to the following full modeling cycle during this lesson (Found on page 61 of the CCLS
and page 72 of the CCSSM).
Scaffolding:
Students are more
engaged when working
with relevant and real data
that interests them.
Websites that provide
data sets are a good
resource for classroom
investigations.
This lesson might need to
be divided into two days if
students need more time
to master the technology.

Step-by-step explanation:
Milo pays $3 per pound for dog food at Pat's Pet
Palace. The graph below represents the cost per
pound of food at Mark's Mutt Market. At which
store will Milo pay a lower price per pound for
dog food?
Answer:
Pat Pet's Palace
Step-by-step explanation:
Price of dog food at Pat Pet's Palace = $3 per pound
Price of dog food at Mark's Mutt Market can be estimated using the graph given.
The graph is a proportional graph, thus, the constant of proportionality between cost and pound = y/x
Using the coordinates of a point on the line, (2.5, 10), constant of proportionality or unit rate = y/x = 10/2.5 = 4.
This means the price of dog food at Mark's Mutt Market is $4 per pound.
Therefore, Milo would pay a lower price per pound for dog food at Pat Pet's Palace.

Explain how to calculate equivalent fractions.
Answer:
Hey there! Thanks for asking your question.
We can multiply the numerators and denominators by any number.
Either way, you will have the same equivalent fraction.
Let's do a practice problem:
[tex]\frac{1}{2} = ?[/tex]
We can multiply the numerator & denominator by 2.
We get the number [tex]\frac{2}{4}[/tex].
So, [tex]\frac{1}{2} = \frac{2}{4}[/tex].

Harriet used the work below to determine the percent equivalent to One-eighth.
Step 1: One-eighth = StartFraction question mark Over 100 EndFraction
Step 2: 8 divided by 100 = 0.08
Step 3: 0.08 times 1 = 0.08
Step 4: 0.08 percent
What was Harriet’s error?
In Step 1, she set up the proportions incorrectly.
In Step 2, she divided 8 by 100 instead of 100 by 8, so she cannot multiply the numerator by the factor.
In Step 3, she multiplied the numerator instead of the denominator by the factor.
In Step 4, she forgot to move the decimal.

x =3
Answer lest edited 3:11 PM Central, 11/24/2020
Answer:
x=5
Step-by-step explanation:
Correct way:
Add 2x to 3x ( 5x )
3x-7=8
Add 7 to 8 ( 15 )
3x=15
Divide 15/3
x= 5
What was wrong:
You need to combine like terms and put the variable on the left side of the equation and then follow the steps above. You also forgot to divide.
Hope this helped, Have a Great Day!!
If AABC = ADEC,
ZB = 48° and ZE = x + 4
Answer:
[tex]x = 44^\circ[/tex]
Step-by-step explanation:
Triangle Congruence
Given triangle ABC is congruent to triangle DEC, then it's true that angle ABC is congruent to angle DEC.
The figure shows that:
[tex]m\angle B = 48^\circ[/tex]
[tex]m\angle E = x + 4^\circ[/tex]
Those angles are congruent, or have the same measure, thus:
[tex]x + 4^\circ = 48^\circ[/tex]
Subtracting 4°:
[tex]x = 48^\circ - 4^\circ[/tex]
[tex]\mathbf{x = 44^\circ}[/tex]
1. Francisco invested $5,000 into an account that earns 3% compounded quarterly. How many
times will Francisco earn interest after keeping the money in the account for 5 years?
2. What will be the value of his account in 5 years if he does not make any additional deposits or
withdrawals?
3. After how many years will Francisco’s account reach $10,000
4. If Francisco wanted to double his money in 12 years, what Interest rate would his account have to earn?
Answer:
10,002.21
Step-by-step explanation:
1)4x5= 20 times
2) principal= 5000
interest rate per year= 3%
compounded times per year=4
time in years = 5
the formula is amt= p*(1+r/n)^(n*t)
thus
Amount = 5805.92
3) If time in years = 23.2
then
amount = 10,002.56
4) Principal = 5,000
interest rate per yr= 5.82%
Compounded times per year = 4
time in years =12
