In a survey the ratio of students who prefer muffins to bagels is 4 to 5 if the number of students surveyed who prefer muffins is 420 how many prefer bagels
Answers
In a survey where the ratio of students who prefer muffins to bagels is 4 to 5 and 420 prefer muffins, 525 students prefer bagels.
Ratio is the relationship between two quantities, normally expressed as the quotient of one divided by the other.
It can be expressed in different ways:
1) Use the ":" to separate the values : a : b
2) Use the word "to" : a to b
3) Write it in fraction: a / b
On the other hand, proportion is the equality of two ratios, such that
a : b = c : d
Given a proportion, the product of its means must be equal to the product of its extremes. That is:
ad = bc
If the ratio of students who prefer muffins to bagels is 4 to 5, and 420 students prefer muffins, the proportion can be written as:
4 : 5 = 420 : n
where n = number of students who prefer bagels
Solving for n,
4n = 5(420)
4n = 2100
n = 525
number of students who prefer bagels = 525

Use graphing technology to approximate the solutions of the equation. x2 + 5x - 12 = | x + 3| + 7
Answers
The solution of the given equations is x=-7 and x=3.
The given equation is x² + 5x - 12 = | x + 3| + 7.
What is the solutions of the equation?A solution is an assignment of values to the unknown variables that makes the equality in the equation true. In other words, a solution is a value or a collection of values such that, when substituted for the unknowns, the equation becomes an equality.
Now, x² + 5x - 12 = | x + 3| + 7 can be rewritten as
x² + 5x - 12 = x + 3 + 7
⇒x² + 5x - 12 = x+10
⇒x² + 5x - 12 -x - 10=0
⇒x² +4x -22 =0
From the obtained graph, the solution of equations is x=-7 and x=3.
Therefore, the solution of the given equations is x=-7 and x=3.

the sum of three numbers is 111. the first number is less than the third. the second number is times the third. what are the numbers?
Answers
The first, second, and third numbers are 11, 80, and 20 respectively.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the first number is a second is b and the third one is c
Now,
The sum of the three numbers is 111
So,
a + b + c = 111
The first number is 9 less than the third
So.
a = c - 9
And the second number is 4 times third
So,
b = 4c
By substitution,
c - 9 + 4c + c = 111
c = 20
b = 4(20) = 80
a = 20 - 9 = 11
Hence "The first, second, and third numbers are 11, 80, and 20 respectively".

Continuing with the expression (x+7), do the following.
(a) By using the Distributive Property twice, show
that this expression is equivalent to
x² +14x+49.
35
(b) Test the equivalency by finding the value of
(x+7)² and x² +14x+49 when x = 3.
x² +14x+49
(x+7)²
Answers
(a) Using the distributive property ( x + 7 )² is equal to x² + 14x + 49.
(b) When x = 3, the expressions ( x + 7 )² and x² + 14x + 49 are equal.
Consider the expression ( x + 7 ),
Now when we square the expression we get,
( x + 7 )² = ( x + 7 ) ( x + 7 )
Using the distributive property,
( x + 7 )² = x( x + 7 ) + 7( x + 7 )
Again by using distributive property,
( x + 7 )² = x² + 7x + 7x + 49
( x + 7 )² = x² + 14x + 49
(b) For the expressions ( x + 7 )² and x² + 14x + 49,
When x = 3,
( x + 7 )² = ( 3 + 7 )²
( x + 7 )² = 10²
(x + 7 )² = 100
When x = 3,
x² + 14x + 49 = 3² + 14 × 3 + 49
x² + 14x + 49 = 9 + 42 + 49
x² + 14x + 49 = 100
Hence, the expressions (x+7)² and x² + 14x + 49 are equal when x = 3.

Lisa and john are bowling. Johns score is three times the difference of Lisa's score and 6. The sum of their scores is 382. Find each students bowling score
Answers
Lisa bowling score is 100.
John bowling score is 282.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
Lisa and John are bowling.
Johns score is three times the difference of Lisa's score and 6.
The sum of their scores is 382.
Now, Let Lisa bowling score = x
Then, John bowling score = 3 (x - 6)
Since, The sum of their scores is 382.
Hence,
x + 3 ( x - 6 ) = 382
After solving,
x + 3x - 18 = 382
4x = 382 + 18
4x = 400
x = 100
Hence, Lisa bowling score = x = 100
And, John bowling score = 3 (x - 6)
= 3 (100 - 6)
= 3 × 94
= 282
Therefore, Lisa bowling score is 100.
And, John bowling score is 282.

Step-by-step explanation:
once we know what the domain and the range of a function is, this is very simple.
the domain is the interval or set of all valid x (input) values.
the game is the interval or set of all valid y (function result) values.
so, what are all the valid x values ? that means for how many months of collection can we use this function to see how many figurines he has ?
well, we can stay with 0 (what he currently has) and go up to 5 (because after 5 months he does not want to continue this behavior).
so, the domain is
0 <= x <= 5 if we allow also fractions of months as input (if this makes sense)
or
x € {0, 1, 2, 3, 4, 5} if we allow only whole numbers.
and the range ? what are the possible result values of the function ?
for x = 0 it starts with y (or f(x)) = 100.
x = 1 gives us 100 + 3×1 = 103
x = 2 gives us 100 + 3×2 = 106
x = 3, 100 + 3×3 = 109
x = 4, 100 + 3×4 = 112
x = 5, 100 + 3×5 = 115
so, the range is
100 <= y <= 115 if we allow fractions of months
or
y = f(x) € {100, 103, 106, 109, 112, 115} if we allow only whole months as values of x.

Answers
The critical value that should be used in constructing the confidence interval is ( 1.592, 1.807 ).
Given that;
Number of residents, n = 7
Z*- value of 90% confidence level equals z* = 0.79
Mean x = 1.7 and deviation σ = 0.36
What is the standard deviation?
Standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean.
Now,
Number of residents, n = 7
Z*- value of 90% confidence level equals z* = 0.79
Mean x = 1.7 and deviation σ = 0.36

Find the slope of the line passing through the given points. how do you know?
Answers
The slope of the line passing through the given points is 0.4 or 2/5.
From the table given below, we have (2, 23) and (5, 24.3).
What is the slope of the line passing through the coordinate points?Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y-values over the change in the x-values.
Put the points (2, 23) and (5, 24.3) in the slope formula and find the slope.
That is, m=(24.3-23)/(5-2)
=1.3/3
=0.4
=4/10 = 2/5
Put m=2/5 and the coordinate points (2, 23) in y=mx+c.
That is, 23=2/5 (2)+c
⇒23 - 4/5 =c
⇒111/5 = c
⇒ c=22.2
Now, equation is y=0.4m+22.2
