The percentage of Mrs. Rogers crafts sold is 62.82%.
Given that, Mrs. Rogers sold 49 out of 78 crafts at the fair.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Percent of crafts sold =Number of crafts sold/Total number of crafts ×100
= 49/78 ×100
= 0.6282×100
= 62.82%
Therefor, the percentage of Mrs. Rogers crafts sold is 62.82%.

Digit realizes that some members of the audience cannot see the bride and groom due to the current seating arrangement. Therefore, the "U" shape in which the wedding party is organized needs to be widened so that the entire audience fits in between the outer boundaries of the "U" shape. In other words, the audience will be located above the upward-opened parabola formed by the bridal party.
What type of transformation is needed to widen the shape in which the wedding party is currently organized?

3x+7+10x=7+13x+10 has {fill in blank} solutions.
-6x-6+8x=-5+2x-1 has {fill in blank} solutions.
choices for both are
infinitely many,one,two,three
Answer and Step-by-step explanation:
3x + 7 + 10x = 7 + 13x + 10
13x + 7 = 13x + 17
0 = 10
No solutions
-6x -6 + 8x = -5 + 2x -1
2x - 6 = -6 + 2x
0 = 0
Many solutions.
The first equation has no solutions.
The second equation has infinitely many solutions.
#teamstrees #WAP (Water And Plant)
Answers:
1. No solutions
2. Infinitely many solutions
Step-by-step explanation:
[tex]3x+7+10x=7+13x+10[/tex]
Add common terms from both sides of the equation (10x and 3x) & (7 and 10)
[tex]13x+7=17+13x[/tex]
Subtract common terms from both sides (13x and 13x)
[tex]7\neq 17[/tex]
7 does not equal 17; thus, there are no solutions
[tex]-6x-6+8x=-5+2x-1[/tex]
Add common terms from both sides of the equation (-6x and 8x) & (-5 and -1)
[tex]2x-6=-6+2x[/tex]
Reorder the right side of the equation
[tex]2x-6=2x-6[/tex]
Since this is a true statement, there are infinitely many solutions

The linear regression equation for a data set is y=1.6x-4.1. If the actual value at x=3 is 0.9,
what is the residual value at x=3?
Answer:
0.2
Step-by-step explanation:
Given the regression model :
y = 1.6x - 4.1
At x = 3
Predicted value = 1.6(3) - 4.1 = 0.7
If actual value at x = 3 is 0.9
The residual value at x = 3 ;
Residual value is the difference between the actual and predicted value :
Actual at x = 3 minus predicted at x = 3
Hence, Residual = 0.9 - 0.7 = 0.2
Residual is the difference between the predicted value and the actual value of the response variable
The residual at x = 3 is 0.2
The linear regression is given as:
[tex]y = 1.6x - 4.1[/tex]
The predicted value at x = 3 is calculated by substituting 3 for x in the linear regression
So, we have:
[tex]y = 1.6 \times 3 - 4.1[/tex]
[tex]y = 4.8 - 4.1[/tex]
[tex]y = 0.7[/tex]
The actual value is given as 0.9.
So, the residual is calculated using:
[tex]Residual =Actual - Predicted[/tex]
This gives
[tex]Residual =0.9 - 0.7[/tex]
[tex]Residual =0.2[/tex]
Hence, the residual at x = 3 is 0.2

1.Find the eqn of line passing through the point of intersection of lines 5x+y=7 and 3y=4x-5 and parallel to the line 2x-y=3
Answer:
y = 2x - 259/115 [slope-intercept]
-230x + 115y = -259 [standard form]
Step-by-step explanation:
First make sure both of the intersecting lines are in standard form: Ax + By = C.
Then, multiply one of the equations by a certain quantity so one of the variables can be canceled out.
For example:
given 5x + y = 7, and 3y = 4x - 5.
You can rearrange the second equation since it is not currently in standard form.
So all we need to do is subtract both sides by 4x since that will leave the constant of C by itself.
3y = 4x - 5 → 3y - 4x = 4x - 5 - 4x →
3y - 4x = -5.
Now adding a negative number is the same as subtracting a positive number, this is because subtraction is the opposite of adding.
So 3y - 4x = -5 = 3y + (-4x) = -5 →
-4x + 3y = -5

Find the range of the function for the given domain.
f(x) = 3x -6;{-2,-1,0,1,2}
What is the range? Choose the correct answer below.
A. {-13, - 9,-6,-3,1)
B. {-12, - 8,-6,- 2,0}
C. {-12, - 8, -7,-2,0)
D. {-12,-9,-6,-3,0}
=================================================
Explanation:
The domain is the set of allowed x inputs. The range is the set of possible y outputs.
The set {-2,-1,0,1,2} represents all the possible x inputs
Let's plug each of those into the equation y = 3x-6 to find the corresponding paired out puts.
Note: y = f(x), so f(x) = 3x-6 is the same as y = 3x-6.
---------------
If x = -2, then,
y = 3x-6
y = 3(-2)-6
y = -6-6
y = -12
We see that x = -2 and y = -12 pair up together.
The value -2 in the domain maps to -12 in the range.
----------------
If x = -1, then,
y = 3x-6
y = 3(-1)-6
y = -3-6
y = -9
The input x = -1 in the domain maps to the output y = -9 in the range
So far the range consists of {-12, -9} in either order.
The answer is between A and D
-----------------
If x = 0, then,
y = 3x-6
y = 3(0)-6
y = 0-6
y = -6
So -6 is also part of the range. We have {-12, -9, -6} so far. The answer is still between A and D.
------------------
If x = 1, then,
y = 3x-6
y = 3(1)-6
y = 3-6
y = -3
The range updates to {-12, -9, -6, -3}
A and D are still equally valid
-------------------
We have one more x value to try
If x = 2, then,
y = 3x-6
y = 3(2)-6
y = 6-6
y = 0
Since y = 0 is in the range, instead of y = 1, this rules out choice A
The answer is therefore D. {-12, -9, -6, -3, 0}

What is the origional price of an object if the total is 878.74 and the tax is 0.07.
My problem/find X
X × 0.07 =b
X + b =$878.78
Answer:
The original price was $821.25
Step-by-step explanation:
The price of an object is $878.74 including a tax of 7%.
We are required to find the original price.
If the tax is 7%, then the total price is 100+7=107% of the original price.
Thus, $878.74 is the 107% of the original price x, thus:
x = $878.74/107*100 = $821.25
The original price was $821.25

What is the volume of a hemisphere with a diameter of 56.7 in, rounded to the
nearest tenth of a cubic inch?
Answer:
Expert Verified
Step-by-step explanation:
the diameter is 57.2 in, then the radius is half that, or 28.6 in. The volume of a sphere is V = (4/3)πr³, and so the volume of this hemisphere is (2/3)πr³
The volume of the hemisphere given its diameter is 47,697.7 in³.
What is the volume?The volume of an object is the amount of space that is in the object. A hemisphere is a three-dimensional object that has the shape of a semicircle.
The volume of the hemisphere = 2/3πr³
r = 56.7 / 2 = 28.35 in
2/3 x 28.35³ x 3.14 = 47,697.7 in³

The campus bookstore knows from the past several semesters that a certain elementary statistics book has a demand that is approximated by a normal distribution with a mean of 250 and a standard deviation of 40. They buy these books for $105 each and sell them to unsuspecting undergraduates at $222 each. All demand for this book is realized by the middle of the semester, at which point the bookstore bundles them up and sells them to a vendor in another country for $40 each. What is the probability of sale for the last book that the bookstore should purchase for sale to a student
Answer:
0.357
Step-by-step explanation:
The computation of the probability of sale for the last book that the bookstore should purchase for sale to a student is shown below
Probability is
= 1 - ((Cs ) ÷ (Cs + co))
= 1 - (($225 - $105) ÷ ($117 + ($105 - $40)))
= 1 - 0.6428
= 0.357
Here Cs represent the notional loss in the case when the demand is underestimated
And Co represent the notional loss in the case when the demand is overestimated

A school cafeteria sold 1,280 slices of pizza the first week, 640 the second week, and 320 the third week. If this pattern continues, in what week will the cafeteria sell 40 slices? Explain how you got your answer.
If you look at the question, You would see a pattern. That pattern is the amount of slices in one week is divided by 2 the next week. So on the fourth week you would do 320/2 and get 160. if you keep carrying on the pattern yourself, you would do: 160/2 = 80. 80/2 = 40. And there's your answer. week 4 we had 160 slices sold. week 5 80 slices sold. Week 6 40 slices sold
Simplify this into your own words if you have to
