Mariko caught 10 rockfish and 14 bluefish on her fishing trip.
Explanation:Let's define the number of rockfish caught as x and the number of bluefish caught as y.
According to the given information, the average weight of each rockfish is 2.5lbs and the average weight of each bluefish is 8lbs.
We can form two equations based on the total weight of all the fish and the total number of fish caught:
Equation 1: x + y = 24 (since Mariko caught a total of 24 fish)Equation 2: 2.5x + 8y = 137 (since the total weight of the fish was 137lbs)We can solve this system of equations to find the values of x and y by either substitution or elimination method. Using the elimination method:
Multiplying Equation 1 by 2.5, we get 2.5x + 2.5y = 60
Subtracting this equation from Equation 2, we get 8y - 2.5y = 137 - 60
Simplifying, we have 5.5y = 77
Dividing both sides by 5.5, we get y = 14
Substituting this value back into Equation 1, we have x + 14 = 24
Simplifying, we get x = 10
Therefore, Mariko caught 10 rockfish and 14 bluefish.
Topic 6: Kites (Gina Wilson, Geometry)
!!!Please help it’s due Wednesday!!!
All four questions please.
Answer:
35.
So that we have:
KLN = 54 JKN =36
LKN = 72 NMJ = 18
KNM = 126 JLM = 72
LJM = 90 KLM = 126
36.
CE = 6√13
37.
m∠Z = 88°
38.
m∠GFE = 85
Step-by-step explanation:
35.
As KLMN is a kite:
+) KL = KN
=> Triangle KLN is an isosceles triangle.
=> m∠KLN = m∠ KNL = m∠KNJ = 54°
In triangle KLN, total measure of three internal angles are 180 degree, so that: m∠KLN + m∠ KNL + m∠ LKN = 180°
=> 54 + 54 + m∠ LKN = 180°
=> m∠ LKN = 180 - 54 - 54 = 72°
+) KM is the bisector of both Angle LKN and Angle LMN
So that we have:
m∠JKN = 1/2 m∠LKN = 1/2 * 72 = 36°m∠NMJ = 1/2 m∠LMN = 1/2 * 36 = 18°+) KM and LN is perpendicular to each other at point J
=> m∠LJM = 90°
+) m∠KLM = m∠KNM; m∠KLM + m∠KNM + m∠LKN + m∠LMN = 360°
=> m∠KLM + m∠KLM + 72 + 36 = 360
=> 2 m∠KLM = 360 - 72 - 36 = 252
=> m∠KLM = 252/2 = 126 = m∠KNM
+) We have: m∠KLM = m∠KLN + m∠JLM
=> m∠JLM = m∠KLM - m∠KLN = 126 - 54 = 72
36.
As BCDE is a kite, we have:
+) BC = BE; CD = DE = 21
+) BD is perpendicular to CE and intersect each other point F
=> Angle CFD = 90
=> Triangle CFD is the right triangle
According to Pythagoras theorem: CF^2 + DF^2 = CD^2
=> CF^2 = CD^2 - DF^2 = 21^2 - 18^2 = 441 - 324 = 117
=> CF = [tex]\sqrt{117} =3\sqrt{13}[/tex]
+) According to the feature of a kite shape, F is midpoint of CE
=> CF = FE = 1/2 x CE
=>CE = 2 x CF = 2 x [tex]3\sqrt{3} = 6 \sqrt{13}[/tex]
So that CE = 6√13
37.
As given, WXYZ is a kite shape.
According to the feature of a kite shape, angle ZWX and angle ZYX are equal to each other.
=> ∠ZWX = ∠ZYX
=> 8x -23 = 6x +11
=> 8x - 6x = 11 + 23
=> 2x = 34
=> x = 34/2 = 17
=> ∠ZWX = 8x - 23 = 8*17 - 23 = 113°
=> ∠ZWX = ∠ZYX = 113°
As WXYZ is a kite shape, so that total measure of 4 internal angles of it are 360 degree
So that we have:
∠Z + ∠ZWX + ∠ZYX + ∠WXY = 360
=> ∠Z + 113 + 113 + 46 = 360
=> ∠Z = 360 -113 -113-46 = 88°
So that the measure of ∠Z is 88°
38.
As GDEF is a kite shape. As we can see, GE is the longer diagonal, so that it is the bisector of both Angle DGF and Angle DEF.
H is on GE and GE is the bisector of Angle DEF, so we have:
m∠HEF = m∠GEF = 1/2. m∠DEF = 1/2 . (12x- 16)= 6x - 8
As GDEF is a kite shape so that the two diagonals DF and GE are perpendicular to each other, so that: m∠EHF = 90
In the triangle EHF, m∠EHF = 90
=> EHF is a right triangle
=> m∠HEF + m∠EFH = 90
=> 6x - 8 + 3x -1 = 90
=> 9x = 90 + 8 + 1 = 99
=> x = 99/9 =11
=> m∠HEF = 6x - 8 = 6*11 - 8 = 58 = m∠GEF
GE is the bisector of both Angle DGF
=> m∠EGF = 1/2. m∠DGF = 1/2 . 74 = 37
In the triangle GEF, total measure of three internal angles are 180
=> m∠GFE + m∠EGF + m∠GEF = 180
=> m∠GFE + 37 + 58 = 180
=> m∠GFE = 85

HELP PLZ FILL IN THE BLANK AND EXPLAIN the missing dimension. Use the scale 1:5
Item Model Actual
Bicycle wheel Diameter: __in Diameter: 2 ft
Final answer:
The model diameter of the bicycle wheel is found using the scale factor of 1:5 and the actual diameter of 24 inches (2 feet). By setting up a proportion and solving for the model diameter, we find it to be 4.8 inches.
Explanation:
To find the missing diameter of the bicycle wheel model when given the actual diameter and a scale factor, we use a proportion:
The scale is given as 1:5, which means 1 unit on the model represents 5 units in reality. First, we need to convert the actual diameter of 2 feet into inches because the model's diameter will be given in inches. There are 12 inches in 1 foot, so 2 feet is 24 inches.
Write the proportion using the scale: 1/5 = model diameter/actual diameter.Substitute the known values into the proportion: 1/5 = model diameter/24 inches.Solve for the model diameter: model diameter = 1/5 * 24 inches.After calculating, the model diameter is 4.8 inches.

What are the coordinates of P'?
Answer:
The coordinates of [tex]P^\prime[/tex] would be [tex](3,\, 0)[/tex].
Step-by-step explanation:
The two points [tex]P[/tex] and [tex]P^\prime[/tex] are on a Cartesian plane.
By convention, the positive [tex]x[/tex]-axis on a Cartesian plane points to the right. As a result,
Moving a point to the right by [tex]a[/tex] units is the same as adding [tex]a[/tex] to its [tex]x[/tex]-coordinate. If the point was initially at [tex](x_0,\, y_0)[/tex], it would be moved to [tex](x_0 + a,\, y_0)[/tex].Moving a point to the left by [tex]a[/tex] units is the same as subtracting [tex]a[/tex] from its [tex]x[/tex]-coordinate. If the point was initially at [tex](x_0,\, y_0)[/tex], it would be moved to [tex](x_0 - a,\, y_0)[/tex].Also by convention, the positive [tex]y[/tex]-axis on a Cartesian plane points upwards. Similarly,
Moving a point upwards by [tex]b[/tex] units is the same as adding [tex]b[/tex] to its [tex]y[/tex]-coordinate. If the point was initially at [tex](x_0,\, y_0)[/tex], it would be moved to [tex](x_0,\, y_0 + b)[/tex].Moving a point downwards by [tex]b[/tex] units is the same as subtracting [tex]b[/tex] from its [tex]y[/tex]-coordinate. If the point was initially at [tex](x_0,\, y_0)[/tex], it would be moved to [tex](x_0,\, y_0 - b)[/tex].In this case,
Point [tex]P[/tex] was initially at [tex](5, -5)[/tex].[tex](5, -5)[/tex] is at [tex](5 - 2, \, -5)[/tex] after it is moved to the left by [tex]2[/tex] units. That's the same as [tex](3,\, -5)[/tex].[tex](3,\, -5)[/tex] is at [tex](3,\, -5 + 5)[/tex] after it is moved upward by [tex]5[/tex] units. That's the same as [tex](3,\, 0)[/tex].Therefore, the coordinates of [tex]P^\prime[/tex] would be [tex](3,\, 0)[/tex].

What is Bayes' Theorem?
Answer:
Bayes' theorem, was named after a British mathematician from the 18th-century named Thomas Bayes. The Bayes´ theorem is a mathematical formula for determining conditional probability. The theorem provides a way to revise any existing predictions or theories, and given new or additional evidence. It updates probabilities.
Hope it helps answer the question:)
Final answer:
Bayes' Theorem is a principle in statistics used to update the probability of a hypothesis in light of new evidence. It combines prior knowledge with observed data to estimate probabilities, and is widely applicable in different fields for making informed decisions.
Explanation:
Understanding Bayes' Theorem
Bayes' Theorem is a fundamental concept in the field of probability and statistics. It offers a way to revise existing predictions or theories in light of new evidence. Bayes' theorem states that the probability of A occurring given that B has occurred is P(A|B) = P(A and B) / P(B). In Bayesian analysis, this is often expressed as the probability of a hypothesis given observed data. The formula can be expanded to include prior knowledge by considering the probability of the hypothesis before observing the data, P(A), and the likelihood of observing the data given the hypothesis, P(B|A).
The theorem has extensive applications across various fields, including science, engineering, and even history. For instance, it can be utilized for the estimation of probabilities of unobserved traits, such as determining the age of individuals based on skeletal indicators. By considering prior knowledge and observed data, Bayes' theorem provides a powerful tool for updating beliefs and making informed decisions.
In practice, Bayesian approaches can incorporate prior information that quantifies existing knowledge about a parameter, which can lead to greater certainty in parameter estimates. The use of Bayesian models is often facilitated by software like WinBUGS, which helps in applying complex Bayesian methods to practical problems

what fraction of a clock is represented of the hands are at 12 and 3 asking for my cousin
Answer:
If the hands are at 12 and 3 you would have 1/3
Step-by-step explanation:
At 12 and 3 the hand will take up a third of the clock because at 12 and 3 the clock hands will have a portion of the clock taken up
The fraction of the clock represented when the hands are at 12 and 3 is 1/4.
What is Fraction?A fraction is a mathematical term that represents a part of a whole. It is written in the form of a numerator over a denominator, separated by a horizontal line. The numerator represents the part of the whole that is being considered, while the denominator represents the total number of equal parts that make up the whole.
If the hands of a clock are at 12 and 3, then the hour hand is pointing directly at the 3, while the minute hand is pointing directly at the 12.
The fraction of the clock represented by this configuration is the fraction of the total circumference of the clock that is between the 12 and the 3.
Since there are 12 hour markings on a clock face, each hour marking represents 1/12 of the total circumference. Therefore, the distance between the 12 and the 3 is 3/12 or 1/4 of the total circumference.
So, the fraction of the clock represented when the hands are at 12 and 3 is 1/4.

find the area of the shaded region. The graph depicts the standard normal distribution with mean 0 and standard deviation 1. Z= 0.74
The area of the shaded region is 0.7257.
The area of the shaded region represents the probability that a standard normal variable will be less than 0.74.
Since the standard normal distribution is symmetrical, the area less than -0.74 is equal to the area greater than 0.74, which can be found using the standard normal table or a calculator.
Using the standard normal table, we find that the area less than -0.74 is 0.2743.
Therefore, the area greater than 0.74 is also 0.2743.
The total area under the curve is 1, so the area less than 0.74 is 1 - 0.2743 = 0.7257.

You and your friend each collect rocks and fossils. Your friend collects three times as many rocks and half as many fossils as you. You collect 20 objects. Your friend collects 20 objects. How many rocks and how many fossils do you each collect?
Answer:
I collect 4 rocks and 16 fossils. While my friend collects 12 rocks and 8 fossils.
Step-by-step explanation:
The number of total objects collected by me = 20
The number of objects collected by my friend = 20
Let us assume:
The number of rocks collected by me = m
The number of fossils collected by me = 2 k
⇒ m + 2 k = 20 .... (1)
So, according to the question:
The number of rocks collected by my friend = 3 x (rocks collected by me)
= 3 x (m) = 3 m
The number of fossils collected by my friend = 1/2 x (fossils collected by me) = 1/2 x (2k ) = k
⇒ 3 m + k = 20 .... (2)
Solving (1)and (2) for the value of m and k, we get:
m + 2 k = 20 ⇒ m = 20 - 2 k ... Put this in (2)
3 m + k = 20 ⇒ 3 (20 - 2 k) + k = 20
⇒ 60 - 6 k + k = 20
or, - 5k = -40
or, k = 40/5 = 8
⇒ k= 8
m + 2(8) = 20
or, m = 4
Hence, the number of rocks collected by me = m = 4
The number of fossils collected by me = 2 k = 2 (4) = 16
Hence, the number of rocks collected by my friend = 3 m = 3 x 4 = 12
The number of fossils collected by my friend = k = 8
Hence, I collect 4 rocks and 16 fossils. While my friend collects 12 rocks and 8 fossils.
You collect 4 rocks and 16 fossils. Your friend collects 12 rocks and 8 fossils.
You and your friend each collect 20 objects. Let's define our variables:
Let R represent the number of rocks you collect. Let F represent the number of fossils you collect.
Your Collection:You collect 20 objects in total:
R + F = 20
Your Friend's Collection:Your friend collects three times as many rocks and half as many fossils as you:
Rocks: 3R Fossils: F / 2
Your friend also collects 20 objects in total:
3R + F / 2 = 20
Solve the EquationsWe have two equations:
R + F = 20 and 3R + F / 2 = 20
First, solve equation 1 for F:
F = 20 - R
Next, substitute this into equation 2:
3R + (20 - R) / 2 = 20
Multiply everything by 2 to clear the fraction:
6R + 20 - R = 40
Simplify:
R + 20 = 40
Subtract 20 from both sides:
5R = 20
Divide by 5:
R = 4
Now, substitute R back into the equation for F:
F = 20 - 4
F = 16
Then, 3R= 12 and F/2 = 8
Thus, you collect 4 rocks and 16 fossils. Your friend collects 12 rocks and 8 fossils.

What is the area of this trapezoid?
Answer:
153 units^2
Step-by-step explanation:
Formula for area of a trapezoid is: A=(b1+b2)*1/2*h
b1=10
b2=24
h=9
Thus:
A=(10+24)*1/2*9
A=34*1/2*9
A=17*9
A=153
So the area of the trapezoid is 153 units^2
Answer: 153
