Questions 12-15. Data from Ivy Tech’s advising center shows that their wait times follow a normal distribution. Use theEmpirical Rule to answer the following questions. 5 10 15 20 25 30 3512. What percent of students will wait between 15 and 25 minutes? (round to the nearest whole number)13. What percent of students will wait less than 20 minutes? (round to the nearest whole number)14. What percent of students will wait more than 35 minutes? (round to the hundredths place)15. If 5,300 students come to the advising center, how many students would wait more than 35 minutes? (round to thenearest student)
Answer:
12. 68%
13. 50%
14. 0.15%
15. 8 students
Step-by-step explanation:
Given a normal distribution with mean 20 and standard deviation 5, you want several probabilities based on the empirical rule.
Empirical ruleThe empirical rule tells you the percentages of a normal distribution that are within 1, 2, or 3 standard deviations of the mean. They are ...
within 1: 68%within 2: 95%within 3: 99.7%12. Between 15 and 25Wait times between 15 and 25 are within 20±5, so within 1 standard deviation of the mean. The percentage of students waiting 15–25 minutes is 68%.
13. Less than 20The mean of the distribution is 20, which is its line of symmetry.
50% of students will wait less than 20 minutes.
14. More than 3535 is 3 standard deviations above the mean, so the fraction in this group is half of the difference between 1 and 99.7%.
0.15% of students will wait more than 35 minutes.
15. How many?Of 5300, the number waiting more than 35 minutes is ...
0.15% × 5300 = 7.95 ≈ 8
About 8 students will wait more than 35 minutes.

Additional comment
These values are based on the empirical rule, as required by the problem statement. The actual number for P(Z>3) is about 0.0013499 (0.13%), and the number of students is about 7.15 ≈ 7. That is, the result using the empirical rule is slightly different than what you get using a calculator, spreadsheet, or table.

6. Solve for x. **THINK! a) what type of angles do you have? b) what is theirrelationship (add up to 90, add up to 180, or congruent)? c) set up an equationand solve *
a) The types of angles present are:
- 1 right angle
- 1 angles of 50 degrees and 1 angle of 4x degrees
b) their relationship is add up to 90°
c) 50° + 4*x° = 90°
4*x° = 90 - 450
x° = 40/4 = 10
x = 10°
which graph represents the equation x - 4y = -16
the given equation is
x - 4y = -16
put x = 0
0 - 4y = -16
y = 4
so at x = 0 ,, y is 4
put x = 4
4 - 4y = -16
-4y = -16- 4
y = 20/4
y = 5
so, at x = 4 the value of y is 5
thus, the correct graph is option B

A map is drawn using the scale 2cm: 100miles. On the map, Town B, is 3.5 cm from Town A and Town C is 2 cm past Town B. How many miles apart are Town A and Town C
SOLUTION
From the question, town B is 3.5cm from town A and town C is 2cm from town B. Therefore C is 5.5 cm from town A.
The scale is 2cm for every 100miles. This means 1cm for every 50 miles.
You get this by dividing 100 by 2.
Now 5.5 cm becomes 5.5 x 50 miles = 275miles.
So town A and town C are 275 miles apart

2.6 km, 109,000 mm, 41.7 hm
The order of the values using the basic unit of meters from smallest to largest. is: 109000 mm < 2.6 km < 41.7 hm
What are the units of measurement of distance or length?
Distance is the gap between any two points under consideration.
The basic unit for measuring distance is the meter.
There are larger as well as smaller units for measuring length or distance which are based on the unit of meter.
The units are as follows:
millimeter, mm = 0.001 m
centimeter, cm = 0.01 m
decimeters, dm = 0.1 m
meter, m = 1 m
kilometer, km = 1000 m
hectometer, hm = 100 m
Now to compare the given quantities making the units same as two quantities can only be compared only when there units are same :
Considering the given values;
2.6 km = 2600 m
109,000 mm = 109 m
41.7 hm = 4170 m
Therefore, after comparison arranging the quantities in order from smallest to largest is 109000 mm < 2.6 km < 41.7 hm

Transit Technologies plans to produce 2-way radios that will sell for $59 per radio. They estimate fixed costs
in manufacturing the radios to be $41,500. The variable costs of producing each radio will be $14. How many
radios must the company sell to break even?
The company should must sell 923 radios to break even.
Fixed cost refer to those costs which do not vary directly with the level of output. For example salary given to staff.
Variable cost that cost which vary directly with the level of output..
The selling price of radio is $59.
Total radios sell are of value $41500. This is the fixed cost.
Let us say that they sell x number of radios,
As we know,
For break even point,
Total revenue = Total cost
Cost of one radio x number of radio = fixed cost plus variable cost of all radios
54x = 41500 + 14x
40x = 41500
x = 922.22~923

QuestionIn ABC, C = 64°, c = 32, and b = 33. What are the two possible values for angle B to the nearest tenth of a degree?Select both correct answers.
Two possible diagrams of the triangle are shown below
To find angle B in each triangle, we would apply the law of sines which is expressed as
a/SinA = b/SinB = c/SinC
For either of the triangles, by applying the sine law, we have
33/Sin B = 32/Sin 64
By crossmultiplying, we have
32 SinB = 33 Sin 64
Sin B = (33 Sin 64)/32 = 0.9269
We would find angle B by finding the inverse of sine 0.9269
Thus,
B = Sin^-1(0.9269) = 68
This is an acute angle. B can also be an obtuse angle. Greater than 90 but less than 180 degrees). Thus, another value for B is

In the game of baseball, home plate is a pentagon.What is the measure of the angle at the bottom of home plate?A. 60°B. 90°C. 120°D. 135°
EXPLANATION
Since the figure is like a pentagon, we need to add the interior angles in order to get the needed angle.
The first part of the figure is composed of a square with two right angles of 90 degrees and two angles of 135, making a total of 90+90+135+135 = 450 degrees.
The left needed angle should add a total of 540 degrees, by the Sum of Interior Angles of a Pentagon Theorem, as follows:
450 + bottom angle = 540
Subtracting -450 to both sides:
bottom angle = 540 - 450
Subtracting angles:
bottom angle = 90 degrees
In conclusion, the value of the bottom angle is 90 degrees.

from the image above, we can see that we have the value of angle and opposite and we need to look for adjacent
trigonometric ratio is given as SOH CAH TOA
[tex]\begin{gathered} \text{soh}=\text{sin}\theta=\frac{opposite}{\text{hypothenus}} \\ \text{cah}=\cos \theta=\frac{adjacent}{hypothenus} \\ \text{toa}=\tan \theta=\frac{opposite}{adjacent} \end{gathered}[/tex]now, let's use the formula of tangent to solve this problem

if A(-3,4) is on BC and divides it in the ratio of BA:AC = 1:2 find C if B is (-9,8)
The coordinate of the point C on the line segment is (9, -4)
How to determine the coordinates of the endpoint C?On the segment, we have the following endpoints
A = (-3, 4)
B = (-9, 8)
The ratio of point A on the line is given as
Ratio, B : C = 1 : 2
Rewrite as
m : n = 1 : 2
The coordinate of point A is calculated using
A = 1/(m + n) * (mx₂ + nx₁, my₂ + ny₁)
Where x and y are the coordinates defined above
So, we have
(-3, 4) = 1/(1+2) * (1 * x + 2 * -9, 1 * y + 2 * 8)
Evaluate
(-3, 4) = 1/3 * (x - 18, y + 16)
So, we have
(x - 18, y + 16) = (-9, 12)
This means that
x - 18 = -9
y + 16 = 12
Solve
x = 9
y = -4
Hence, the location of the point C is (9, -4)

12–15. Melvin Indecision has difficulty deciding whether to put his savings in Mystic Bank or Four Rivers Bank. Mystic offers 10% interest compounded semiannually. Four Rivers offers 8% interest compounded quarterly. Melvin has $10,000 to invest. He expects to withdraw the money at the end of 4 years. Which bank gives Melvin the better deal?
The better deal between the offer at Mystic Bank and Four Rivers Bank is the deal at Mystic Bank.
What is the better deal?In order to determine which bank has the better offer, the future value of the investment options have to be determined.
The future value of an investment is a function of the amount investment, the number of compounding, the years of the investment and the interest rate.
When an investment is compounded semi-annually, it means that it grows exponentially twice in a year. When an investment is compounded quarterly, it means that is grows exponentially four times in a year.
The formula for calculating future value:
FV = P (1 + r)^nm
Where:
FV = Future value P = Present value R = interest rate m = number of compoundingN = number of yearsInterest rate at Mystic bank = 10% /2 = 5%
Interest rate at Four Rivers Bank = 8% / 4 = 2%
Future value of the investment at Mystic bank :
$10,000 x (1.05)^(2 x 4) = $14,774.55
