Answer:
Quinn can expect to pick blue 40 times
Step-by-step explanation:
the probability of picking blue is stated as 2/10 which can be reduced to 1/5
multiply the number of times they pick a marble ( shown as 200) by the probability of picking a blue one ( 1/5)
200 x 1/5 = 200 / 5 = 40
Quinn can expect to pick blue 40 times
Answer:40 blue marbles
Step-by-step explanation:
First find the probability of a blue marble
P (blue) = number of blue marbles / total marbles
= 2 blue/ ( 5+3+2) total
= 2/10
=1/5
We can use this since we return the marble to the bag each time
We multiply this by 200 for the number of times it is picked
200 * 1/5 = 40
We should expect to pick 40 blue marbles
Jamal has an 8-foot piece of wood that he wants to cut to build a step for his tree house if each piece is going to be 5/6. What is the greatest number of pieces he will be able to use

Step-by-step explanation:
A military commander has been assigned the task of defending an asset from enemy air attack. Commander has two types of air defense missiles; 5 missiles each of type I and type II are available for deployment. Each type I missile costs 7 units for installation and each type II missile costs 8.5 units for installation. The total budget available is 60 units. Each type I missile requires 6 persons for handling whereas each type II requires 2 persons. There are only 32 trained persons to handle the missiles at the site. If the site is not defended the enemy aircrafts are estimated to destroy 95% of the asset value. If one type I missile is deployed on the site, it is expected to save 13% of the asset value. Similarly, deployment of one type II missile is estimated to save 9% of the asset value. In other words, the enemy aircrafts which were earlier capable of destroying 95% of the asset value are able to destroy 82% of the asset value in the presence of one missile of type I and 86% of the asset value in the presence of one missile of type II. Formulate an LP to determine the mix of missiles that provides maximum protection to the asset against an attack of enemy aircrafts aiming simultaneously.
Step-by-step explanation:
we have A and B
for A,
95-82 = 13
for B,
95-86 = 9
cost of A = 9
cost of B = 8.5
total = 60
for person
A = 6,
B = 2
Total = 32
setting up objective function:
13x + 9y
constraints:
0≤x≤5, 0≤x≤5
7x + 8.5y ≤ 60
6x + 2y ≤ 32 this can be reduced by 2
3x + y≤16
this would take us to a bounded region which has the corner points and the objective values in the attachment i added.

The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
The table below shows the typical hours worked by employees at a company.
Based on the data given:
Total number of hours = 0+ 8.5 + 9.5 + 7.5 + 8 + 8.5 + 4
Total number of hours = 46
Hourly pay = (40×$14) + (6×$21)
Hourly pay = $686 per week
Annual earnings = 52×686
Annual earnings = $35,672
The new employee should select the salary pay based on the calculations above since a $37,000 yearly income is more than a $35,672 hourly wage.
Thus, the new employee should select the salary pay because a $37,000 yearly income is more than a $35,672 hourly wage.

Find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon. Round to the nearest tenth, if necessary. 24 b 15, 345 24, 156 7.5, 172.5 15, 165
Answer: Find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon. Round to the nearest tenth, if necessary. 24 b 15, 345 24, 156 7.5, 172.5 15, 165
Step-by-step explanation: sum, S, of the measure of the interior angles of a polygon with n sides is: ... The sum of the interior angles of a 24 -gon is 3960. ... angles of a polygon is (n−2)⋅180 , where n is the number of sides. ... Each exterior angle measures 36024=15 . ... The sum of the 24 interior angles is then 24⋅165=3960 .
The administrator of a $200,000 trust fund must adhere to following guidelines.
a. The money may be invested in three different types of securities: a utilities stock paying a 9% dividend, an electronics stock paying a 4% dividend, and a bond paying 5% interest.
b. The amount invested in the stocks cannot be more than half the total amount invested; the amount invested in the utilities stock cannot exceed $40,000; and the amount invested in the bond must be at least $70,000.
c. The total amount need not be fully invested at any one time.
Required:
Setup an LP problem to maximize profit.
Step-by-step explanation:
let us give all the quantities in the problem variable names.
x= amount in utility stock
y = amount in electronics stock
c = amount in bond
“The total amount of $200,000 need not be fully invested at any one time.”
becomes
x + y + c ≤ 200, 000,
Also
“The amount invested in the stocks cannot be more than half the total amount invested”
a + b ≤1/2 (total amount invested),
=1/2(x + y + c).
(x+y-c)/2≤0
“The amount invested in the utility stock cannot exceed $40,000”
a ≤ 40, 000
“The amount invested in the bond must be at least $70,000”
c ≥ 70, 000
Putting this all together, our linear optimization problem is:
Maximize z = 1.09x + 1.04y + 1.05c
subject to
x+ y+ c ≤ 200, 000
x/2 +y/2 -c/2 ≤ 0

c ≥ 70, 000
a ≥ 0, b ≥ 0, c ≥ 0.

We have to determine, which descriptions of a histogram are true?
According to the question,
A histogram meaning can be stated as a graphical representation that condenses a data series into an easy interpretation of numerical data by grouping them into logical ranges of different heights which are also known as bins.
Characteristics of a Histogram are as follows;
A histogram is used to display continuous data in a categorical form.
In a histogram, there are no gaps between the bars, unlike a bar graph.
The width of the bins is equal.
A histogram is a type of representation of a data set where bars are used to represent the frequencies.
The area of these bars is said to be proportional to the frequency of the variable.
The peak of a histogram represents the highest value of frequency. Also, the peak is a bar that is higher than the other bars around it.
In a histogram intervals wherein bars cannot be seen would represent the frequency of that would zero.
Also, if the histogram is said to be symmetrical, then the data should be distributed evenly.
A peak is where the frequency is the highest.
A cluster is a group of bars, meaning the frequency is higher in these intervals.

Traditionally, the earth's surface has been modeled as a sphere, but the World Geodetic System of 1984 (WGS-84) uses an ellipsoid as a more accurate model. It places the center of the earth at the origin and the north pole on the positive z-axis. The distance from the center to the poles is 6356.523 km and the distance to a point on the equator is 6378.137 km. Meridians (curves of equal longitude) are traces in planes of the form y=mx.
Required:
a. Find an equation of the earth's surface.
b. What is the shape of these meridians?
Answer:
a) x²/(6378.137)² + y²/(6378.137)² + z²/(6356.523)² = 1
b) x²/(6378.137)²/(1+m²) + z²/(6356.523)² = 1
Step-by-step explanation:
a)
We know that the general equation of the ellipsoid with center at the origin is
x²/a² + y²/b² + z²/c² = 1
Since the north pole is along the z-axis and north pole is at a distance of 6356.523 km from the center, so c = 6356.523
And the distance between center to a point on the equator is 6378.137 km so we have, a = b = 6378.137
Thus, the equation of the earth's surface as used by WGS-84 is
x²/(6378.137)² + y²/(6378.137)² + z²/(6356.523)² = 1
b)
Meridians are traces in planes of the form y=mx, so the equation of paraboloid gives;
x²/(6378.137)² + m²x²/(6378.137)² + z²/(6356.523)² = 1
x²/(6378.137)²/(1+m²) + z²/(6356.523)² = 1

Answer:
174 yards squared
Step-by-step explanation:
If Whitley park is a rectangular park with a perimeter of 70 yards. One side of Whitley park is 18 feet long then 174 yards is the area.
What is Area of Rectangle?Area of rectangle is length times of breadth.
We know that 18 feet=6 yards.
It is given that One side of Whitley park is 18 feet long, so one side of length is 6 yards.
2(Lenght+breadth)=70
2(L+6)=70
2l+12=70
2l=70-12
2l=58
l=29 yards
Now
Area =Length×breadth
