Answers
The probability that the next number pointing north is between 2 and 7 is 13/18 .
1) The circle is divided into 9 parts.
Now the parts are uneven.
So the data about the spins is required to calculate the probability .
The total number of items in the box = 18
favorable outcomes (between 2 and 7) = 13 possible outcome.
Required probability
= favorable outcome / total outcome
= 13 / 18
2) Using the Venn diagram we can calculate the various parts of the problem:
Shoppers at big-box store or online or local store = sum of all the shoppers = 109+57+107+18+17+38+34 = 380 shoppers
3) Shoppers made purchase online or locally owned shop but not at a big box store = 107 + 38 + 34 = 179 shoppers.

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 60% pure antifreeze. The company wants to obtain 180 gallons of a mixture that contains 35% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed?
Answers
The gallons of water and premium antifreeze solution that must be mixed are equal to 60 gallons and 120 gallons respectively.
How to determine the gallons of water and premium antifreeze solution?In order to calculate the gallons of water and premium antifreeze solution, we would assign variables to the gallons of water and premium 60% antifreeze that is required, and then translate the word problem into algebraic equation as follows:
Let the variable x represent the gallons of water.Let the variable y represent the premium 60% antifreeze.Since the premium antifreeze solution contains 60% premium antifreeze, we have the following mathematical expression:
x + y = 180 ....equation 1.
0.60y = 0.40(180) ....equation 2.
From equation 2, we have:
0.60y = 0.40(180)
0.60y = 72
y = 72/0.60
y = 120 gallons of premium antifreeze.
For the gallons of water, we have the following:
x + y = 180
x = 180 - y
x = 180 - 120
x = 60 gallons of water.

Juan scored a total of 37 points in the basketball game, and he scored p points in the second half of the game. Write an expression to determine the number of points he scored in the first half of the game. Then, find the number of points he scored in the first half of the game if he scored 11 points in the second half of the game.
Answers
Step-by-step explanation:
Juan scored 26 points in the first half of the basketball game, and then scored n points in the second half of the game.
a. An expression to determine the number of points he scored in all will be:
First half points= 26
Second half points= n
Total points= First half points + Second half points
= 26 + n
b. The number of points Juan scored in all if he scored 18 points in the second half of the game will be:
First half points= 26
Second half points= 18
Total points= First half points + Second half points
= 26 + 18

The equation of the line that goes

Answers
The equation of the line that goes through the point (3, 1) and is perpendicular to the line 2x + 4y = 5 can be written in the form y = mx + b where m= 2 and b= -5.
According to the question,
We have the following information:
Points = (3,1)
Equation of the line: 2x+4y = 5
Now, converting this line into y = mx+b form:
4y = -2x+5
y = -2y/4+5/4
y = -y/2+5/4
Now, the slope of this line is -1/2.
Slope of the line perpendicular to this line will be 2 (-1/m).
Now, the equation of the line will be:
(y-y') = m(x-x')
x' = 3 and y' = 1
y-1 = 2(x-3)
y-1 = 2x-6
y = 2x-6+1
y = 2x-5
The value of m is 2 and b is -5.
Hence, the equation of the line that goes through the point (3, 1) and is perpendicular to the line 2x + 4y = 5 can be written in the form y = mx + b where m= 2 and b= -5.

A carpenter cut the top section of a window frame with a 37º angle on each end. The side pieces each have a 50º angle cut at their top ends, as shown. Will the side pieces of the frame be parallel? Explain. Diagram not to scale.
SOMEONE PLEASE HELP ME!
Answers
Based on the given parameters about a carpenter cutting the top section of a window frame, the side pieces of the frame are not parallel.
How to show that the side pieces of the frame are parallel?Parallel lines are lines which are equally distant from one another at all points.
To show that the side pieces of the frame are parallel:
The interior angles are equal in measure and the sum of the interior angles must be equal to 180°
The two given side pieces of the window frame are also equal in measure.
If the sum of both side angles is equal to 180∘, then, the sides are parallel.
Adding one side of the interior angle:37∘ + 50∘ = 87∘
Adding both sides of the angle:2(37∘ + 50∘)
= 2(87∘)
= 174∘
Hence,
174∘ < 180∘
So therefore, the sides pieces of the window frame cut by the carpenter are not parallel.

The magnitude of the second earthquake, using an logarithmic function, is of:
5.77.
How to obtain the magnitude of the earthquakes?The magnitude of an earthquake is given by the logarithmic rule presented as follows:
[tex]M = \frac{2}{3}\log{\left(\frac{E}{E_0}\right)}[/tex]
The first earthquake had a magnitude of 3.9, hence it's energy is obtained as follows:
[tex]3.9 = \frac{2}{3}\log{\left(\frac{E}{E_0}\right)}[/tex]
[tex]\log{\left(\frac{E}{E_0}\right)} = \frac{3.9 \times 3}{2}[/tex]
[tex]\log{\left(\frac{E}{E_0}\right)} = 5.85[/tex]
The logarithm and the base 10 are inverse functions, hence the base 10 is applied to both sides to isolate the energy variable as vollows:
[tex]\frac{E}{E_0} = 10^{5.85}[/tex]
[tex]E = 707945.784E_0[/tex]
For the second earthquake, it's energy was 650 times greater, hence:
[tex]E = 707945.784 \times 650E_0 = 460164760E_0[/tex]
Hence it's magnitude is obtained as follows:
[tex]M = \frac{2}{3}\log{\left(\frac{460164760E_0}{E_0}\right)}[/tex]
M = 5.77.

APR
Basically, APR refers the refers to the yearly interest generated by a sum that's charged to borrowers or paid to investors.
Given,
Maxine's credit card has an APR of 21.99%.
Here we have to find the monthly interest charge if her current monthly balance, before interest, is $2,586.50.
While we looking into the given question, we have identified the following,
APR = 21.99%
For one month the APR is calculated as,
APR = 21.99 / 12
APR = 1.8325%
When we convert this into decimal form then we get,
=> APR = 1.8325/100
=> APR = 0.01835
And the current monthly balance is $2,586.50,
So, the interest change for the month is
=>2,586.50 x 0.01835
=> 47.46
Therefore, the monthly interest charge is $47.46.

The polynomial of p(x) is -24 (x² + 15x + 54) with the satisfying's conditions degree 3.
Given,
An nth degree polynomial p meets the requirements listed below:
p is of degree 3.
-9 is a zero, with multiplicity 2, of p.
-6 is a zero, with multiplicity 1, of p.
p(-1) = -960
We have to determine an nth degree polynomial that satisfier the conditions.
Let the polynomial be p(x) whose zero are -9 and -6
a be the coefficient.
p(x) = a (x+9) (x+6)
p(x) = a(x² + 6x + 9x + 54)
p(x) = a(x² + 15x + 54)
Now, take x = -1
p(-1) = a (-1² + 15 x -1 + 54)
-960 = a ( 1 - 15 + 54)
-960 = a x 40
a = -960/40
a = -24
We get,
p(x) = -24 (x+9) (x+6)
p(x)= -24 (x² + 15x + 54)

Answers
The probability that Rebecca's first flight was delayed is 75%.
What is probability?Probability is the ratio or odds of an expected outcome occurring when there are many possible outcomes.
Probability is always a fractional value lying between 0 and 1. When the expected outcome is certain, the probability is said to be one. When it is uncertain, the probability is zero.
Like ratios, probability is depicted as decimals, fractions, or percentages when there is no 100% certainty or uncertainty.
The probability of Rebecca's first flight leaving on time = 0.25
The probability of Rebecca's first flight being delayed = 0.75 (1 - 0.25)

Width = 8 less than half the length
This means that
w = 1/2l - 8
The perimeter of a rectangle is
perimeter = 2 * (l + w)
So, we have
P = lw
This gives
P = 2 * (l + 1/2l - 8)
P = 2 * (1.5l - 8)
Open the brackets
P = 3l - 16
Substitute the known values in the above equation So, we have the following equation
5000 ≤ 3l - 16 < 8000
The above represents the inequality
See attachment for the graph
From the graph, we have the solution to be
l = 1672 (approximately)
Recall that:
w = 1/2l - 8
So, we have
w = 1/2 * 1672 - 8
Evaluate
w = 828
Hence, the possible length is 1672 ft

Answers
Answer:
1.914 %
Step-by-step explanation:
Compounded quarterly means 4 periods per year = n
interest in decimal form per period i = .019/4 = .00475
Formula
annual yield = ( 1+ i)^n -1
(1+ .00475)^4 -1 = .01914 = ~ 1.914%
