How many coins did julia collect
Answer:
The number of coins Julia found is 5
Step-by-step explanation:
We know that the total number of gold coins collected divided by the number of people collecting is 6. So we can set up an equation:
[tex]\frac{6+5+6+8+x}{5}=6[/tex]
this simplifies to:
[tex]\frac{25+x}{5}=6[/tex]
Using the multiplication property of equality and multiplying both sides by we get:
25+x=30
Then finally, using the subtraction property of equality we get our answer:
x=5

Which modified box plot represents the data set?
2, 8, 18, 7, 42, 12, 16, 14, 11, 4, 1, 10, 19
Answer:
D
Step-by-step explanation:
Arrange the data 2, 8, 18, 7, 42, 12, 16, 14, 11, 4, 1, 10, 19 in ascending order:
1, 2, 4, 7, 8, 10, 11, 12, 14, 16, 18, 19, 42
The number 42 is an outlier of the data.
1, 2, 4, 7, 8, 10, 11, 12, 14, 16, 18, 19, 42
Write a five-number summary:
Min: 1
Q1: 5.5 (the average between the middle terms of first half of the data)
Med: 11 (the middle term of the data)
Q3: 17 (the average between the middle terms of second half of the data)
Max: 19
Outlier: 42
Only option D shows
Answer:
The last box plot
Step-by-step explanation:
A box plot is simply a graphical representation of the 5 number summary of a data set;
The minimum, first quartile, median, third quartile, and the maximum
in that order.
We can therefore arrange our given data set from the least to the greatest value;
1, 2, 4, 7, 8, 10, 11, 12, 14, 16, 18, 19, 42
The value 42 is an outlier since it is more extreme than the rest of the values.
From our arrangement of the data values above, we can note the following;
The minimum value is 1
The maximum value is 19
42 is an outlier, will be represented by a dark circle
The box-plot that matches the above is the last one and is thus the correct modified box-plot for the data

Given these two terms in a geometric sequence, find the recursive formula.
a1=4
a6=31104
Answer:
[tex]\boxed{ a_{n} = 6a_{n-1}}[/tex]
Step-by-step explanation:
Step 1. Determine the common ratio
The formula for the nth term of a geometric sequence is
aₙ = a₁rⁿ⁻¹
Data:
a₁ = 4
n = 6
a₆ =31 104
Calculation:
31 104 = 4r⁵
r⁵ = 7776
[tex]r = \sqrt [5]{7776}[/tex]
r = 6
aₙ = 4(6)ⁿ
Step 2. Determine the recursive formula.
aₙ = 4(6)ⁿ
aₙ₋₁ = 4(6)ⁿ⁻¹
[tex]\dfrac{a_{n}}{{a_{n-1}}} = \dfrac{4(6)^{n} }{4(6)^{n-1}} = 6\\\\a_{n} = 6a_{n-1}[/tex]
The recursive formula for the series is [tex]\boxed{ a_{n} = 6a_{n-1}}[/tex]
The polynomial function f(x)=-x^3+x^2+14x-24 has zeros at x=-4, x=3, and x=2. Which of the following graphs represents the function?
Answer:
Assuming the choices are only of C and D, D would be the graph of the function.
Step-by-step explanation:
There are many things that would cause D to be the graph of f(x).
Firstly, D has the end behavior of a [tex]-x^{3}[/tex] function.
Secondly, it has correct zeroes
Lastly, Its y-intercept is -24, which is the case of the function f(x) as
[tex]f(0) = -24[/tex]
the function y=5/3× is shifted up 4 units what is the equation of the new function
Answer:
y = 5/3x + 4
Step-by-step explanation:
the y-intercept in the original equation lies at (0,0), as there is no given value for the y intercept.
when you move the graph up 4 units, you are going along the y-axis, meaning the y intercept will change to be (0,4)
y = 6x − 4
y = 5x − 3
Part A: In your own words, explain how you can solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations.
Part B: What is the solution to the pair of equations?
can it also be simple
Answer:
Part B: [tex]\displaystyle [1, 2][/tex]
Part A: Set both equation equal to each other by Substitution, since our y-values are already given to us.
Step-by-step explanation:
6x - 4 = 5x - 3
- 6x + 3 - 6x + 3
____________
[tex]\displaystyle -1 = -x; 1 = x[/tex]
Plug this coordinate back into the above equations to get the y-coordinate of 2.
y = mx + b [where b is the y-intercept and the rate of change (slope) is represented by m]
[tex]\displaystyle y = 5x - 3; [0, -3]; 5 = m \\ y = 6x - 4; [0, -4]; 6 = m[/tex]

A 150lb woman receives 24 grams of medicine. How many grams would a 120lb woman get
Answer:
19.2 grams
Step-by-step explanation:
We can solve the problem via ratio and proportions or simply through cross-multiplication;
we can formulate the following proportions;
(medication/weight) = constant
24/150 = x/120 = constant
where x is the quantity of medication for the 120 lb woman.
solving for x yields;
x = (24/150)*120
x = 19.2 g
Answer:
The correct answer is 19.2 grams
Step-by-step explanation:
It is given that, a 150lb woman receives 24 grams of medicine
To find the amount of medicine
150lb woman receives 24 grams
From the given information we can write,
1lb woman receives 24/150 grams
120lb woman receives = (24/150) * 120
= 19.2 grams
Therefore 120lb woman get 19.2 grams
The correct answer is 19.2 grams

the graph of f(x) shown below has the same shape as the graph of g(x)=x^2 but is shifted down 5 units and to the left 4 units (thank you)
Answer:
D. [tex]F(x)=(x+4)^2-5[/tex]
Step-by-step explanation:
The parent function is [tex]G(x)=x^2[/tex].
This function has its vertex at the origin (0,0).
When this function is shifted down 5 units and to the left 4 units, then its new vertex will be at (-4,-5)
The vertex form of the equation is given by;
[tex]F(x)=a(x-h)^2+k[/tex] where (h,k)=(-4,-5) is the vertex and a=1 because of the parent function.
Hence its equation is
[tex]F(x)=(x+4)^2-5[/tex]
Answer:
Option C
Step-by-step explanation:
A function g(x) = x² has been given as the parent function.
This function then shifted 5 units down.
Translated function formed will be f(x) = x² - 5
Further this graph has been shifted 4 units to the left then the function will become
f(x) = [x - (-4)]² - 5
f(x) = (x + 4)² - 5
Therefore, option C is the answer.

A garden table and a bench cost $741 combined. The garden table costs $91 more than the bench. What is the cost of the bench?
Answer:
bench: $416; table: $325.
Step-by-step explanation:
Let t and b represent the costs of the table and bench respectively. Then:
t + b = $741, and t = b + $91.
Substituting b + $91 for t in the first equation, we get:
b + $91 + b = $741
Then 2b = $741 - $91, or 2b = $650
Then the bench costs $325 and the table ($325 + $91), or $416.

At a local company, the ages of all new employees hired during the last 10 years are normally distributed. The mean age is 38 years old, with a standard deviation of 10 years. Find the percent of new employees that are no more than 30 years old. Round to the nearest percent.
Answer:
P = 21%
Step-by-step explanation:
We look for the percentage of employees who are not more than 30 years old.
This is:
[tex]P = \frac{x}{n} *100\%[/tex]
Where x is the number of new employees who are not over 30 years old and n is the total number of new employees.
We do not know the value of x or n. However, the probability of randomly selecting an employee that is not more than 30 years old is equal to [tex]P = \frac{x}{n}[/tex]
Then we can solve this problem by looking for the probability that a new employee is not more than 30 years old.
This is:
[tex]P(X< 30)[/tex]
Then we find the z-score
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
We know that:
μ = 38 years
[tex]\sigma = 10[/tex] years
So
[tex]Z = -0.8[/tex]
Then
[tex]P (X<30) = P (\frac{X- \mu}{\sigma} < \frac{30-38}{10})\\\\P (X<30) = P(Z<-0.8)[/tex]
By symmetry of the distribution
[tex]P(Z<-0.8)=P(Z>0.8)[/tex]
Looking in the normal standard tables
[tex]P(Z>0.8)=0.211[/tex]
Finally P = 21%

Answer:
Yes, it is a right triangle.
Step-by-step explanation:
Look at the points:
(1, 1), (1,4)
(1,4), (4,4)
(4,4), (1,1)
Find the slope between each point: In respective order, the first one is undefined, the second one has a slope of zero, and the third has a slope of 1. Because undefined slope is completely vertical (parallel to the y axis, and the slope of 0 is completely horizontal (parallel to the x axis), they are perpendicular (as it is transitive since the x axis is perpendicular to the y axis). Therefore, we know that anything that is perpendicular created a right angles', and thus, the any triangle with a right angle is a right triangle.

Complete the steps to factor 12x3-9x2+8x-6 by grouping
Answer:
(4x−3)(3x²+2)
Step-by-step explanation:
Factor 12x3−9x2+8x−6
12x3−9x2+8x−6
=(4x−3)(3x2+2)
The factored form of the expression 12x³ - 9x² + 8x - 6 by grouping is (3x² + 2)(4x - 3).
To factor the expression 12x³ - 9x² + 8x - 6 by grouping, we can group the terms in pairs and factor out the common factors.
Step 1: Group the terms in pairs
(12x³ - 9x²) + (8x - 6)
Step 2: Factor out the greatest common factor from each pair
3x²(4x - 3) + 2(4x - 3)
Step 3: Notice that both terms now have a common factor of (4x - 3)
(3x² + 2)(4x - 3)
Therefore, the factored form of the expression 12x³ - 9x² + 8x - 6 by grouping is (3x² + 2)(4x - 3).

The length of a rectangle is 7 centimeters less than its width. What are the dimensions of the rectangle if its area is 144 square centimeters?
Answer:
Width = 16 cm
Length = 9 cm
Step-by-step explanation:
Width = x cm
Length = x - 7
Area = 144 cm²
x(x - 7) = 144
x² - 7x = 144
x² - 7x - 144 = 0
(x - 16)(x + 9) = 0
x = 16 or x = -9 (rejected)
Width = 16 cm
Length = 16 - 7 = 9 cm
The width is determined to be 16 cm, and the length is 9 cm.
The student is asking for the dimensions of a rectangle given an area of 144 square centimeters and a length that is 7 centimeters less than its width. To find the dimensions, we can let the width be represented by w and the length by w - 7 (since the length is 7 centimeters less than the width). The area of a rectangle is calculated by multiplying the length by the width, which in this equation would be w(w - 7). We can set this equal to the given area of 144 square centimeters and solve for w.
Setting up the equation: w(w - 7) = 144. This simplifies to w^2 - 7w - 144 = 0.
To solve for w, we need to factor the quadratic equation, which results in (w - 16)(w + 9) = 0. The width can be 16 cm because it must be a positive value. Subsequently, the length is 16 - 7 = 9 cm.
Therefore, the dimensions of the rectangle are 16 cm in width and 9 cm in length.
