The statements DF=EG, EF=DG and ∠DEG ≅ ∠FGE are true for parallelogram DEFG.
What is Quadrilateral?a quadrilateral is a four-sided polygon, having four edges and four corners.
DEFG is a parallelogram.
A parallelogram is a simple quadrilateral with two pairs of parallel sides.
The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
DF=FG is a true statement.
The diagonal passing through a parallelogram are equal in length.
EF=DG is a true statement
The opposite sides of a parallelogram are equal.
∠DEG ≅ ∠FGE are congruent angles.
Because the opposite angles of a triangle are equal in meausure.
Hence, the statements DF=EG, EF=DG and ∠DEG ≅ ∠FGE are true for parallelogram DEFG.

Cos A = (12² + 14² - 14²) / 2(12)(14)
Cos A = 144 / 336

Answer:
x = 8
y = 6
Step-by-step explanation:
Recall that one of the properties of a parallelogram is that the diagonals bisect each other, which means they divide each other into equal segments.
Therefore,
LP = PN
x = y + 2 (eqn. 1)
PM = KP
2x - 8 = y + 10 (eqn. 2)
Substitute x = y + 2 into eqn. 2 to find y
Thus:
2(y + 2) = y + 10
2y + 4 = y + 10
Take like terms
2y - y = -4 + 10
y = 6
Substitute y = 6 into eqn. 1 to find x:
x = y + 2 (eqn. 1)
x = 6 + 2
x = 8

O B. -0.998 = -3.6x + 12.8
O c. y = 12.8x - 3.6
D. y = -0.998x + 12.8
Answers
Answer:
Step-by-step explanation:
A y = -3.6x + 12.8
The line of best fit is,
⇒ y = - 3.6x + 12.8
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, Given that;
⇒ y = ax + b.
And, the best fitting line has values of a = - 3.6 and b = 12.8.
Hence, All you need do is put that into the general equation and try different values for it.
So you have y = - 3.6 x + 12.8
Now Let's run a couple of numbers.
The table shows 1 and 9 for the first entry. This means when x = 1, y should come pretty close to nine.
y = - 3.6(1) + 12.8
y = 9.2
Which is not a bad result for x = 1
You might want to check to see if anything else comes closer in your choices. If it does, then you have to try other points.
C
-0.998 = -3.6(1) + 12.8
This answer cannot work. We've already shown that x =1 will leave us close to 9 not -998
So, C is incorrect.
B
y = 12.8x - 3.6
Let x = 1
y = 12.8(1) - 3.6
y = 9.2 is right by coincidence. We must try another value. The hardest one is going to be 5 and - 5
y= 12.8*5 - 3.6
y = 64 - 3.6 which is no where's near - 5.
So B is wrong.
A
y = -0.998(1) + 12.8 Does this give 9 or anywhere near it? 11.802 You might argue that that is not a bad result. So let's try another pair.
x = 3. y should come to somewhere near 2.
y = -0.998 * 3 + 12.8 which comes to roughly nine. You can check this out.
It is not close enough to 2 to be acceptable.
Thus, The correct option is,
⇒ y = - 3.6x + 12.8

Recent incidents of food contamination have caused great concern among consumers. An article reported that 31 of 80 randomly selected Brand A brand chickens tested positively for either campylobacter or salmonella (or both), the leading bacterial causes of food-borne disease, whereas 61 of 80 Brand B brand chickens tested positive.
Required:
a. Does it appear that the true proportion of non-contaminated Perdue broilers differs from that for the Tyson brand? Carry out a test of hypotheses using a significance level 0.01 by obtaining a P-value.
b. If the true proportions of non-contaminated chickens for the Perdue and Tyson brands are 0.50 and 0.25, respectively, how likely is it that the null hypothesis of equal proportions will be rejected when a 0.01 significance level is used and the sample sizes are both 80?
Answers
Answer:
a) z(s) is in the rejection region for H₀ we reject H₀.
We have enough support to conclude that the two populations are different
z(s) is in the rejection region so we reject H₀
The two population have a different proportion of non-contaminated food
Step-by-step explanation:
Conditions:
-Independent samples
-Random samples
- Size samples big enough
a) A Brand Chickens Sample:
sample size n₁ = 80
We will go through a z- test
number of contamination cases x₁ = 31
Then p₁ = 31/80 p₁ = 0.3875 and q₁ = 1 - p₁ ; q₁ = 1 - 0.3875
q₁ = 0.6125
B Brand Chickens Sample:
sample size n₂ = 80
number of contamination cases x₂ = 61
Then p₂ = 61/80 p₂ = 0.7625 and q₂ = 1 - p₂ ; q₂ = 1 - 0.7625
q₂ = 0.2375
Hypothesis Test:
Null Hypothesis H₀ p₂ = p₁
Alternative Hypothesis Hₐ p₂ ≠ p₁
The alternative hypothesis call for a two-tail test ( ≠ ) we will test if the proportion differs )
A significance level α = 0.01 then α/2 = 0.005
From z -Table α/2 = 0.005 correspond to z(c) = 2.575
To calculate z(s)
z(s) = ( p₂ - p₁ ) / √( p₁*q₁/n₁) + (p₂*q₂)/n₂)
z(s) = ( 0.7625 - 0.3875 ) / √(0,3875*0.6125)/80 + (0.7625*0.2375)/80
z(s) = ( 0.375 ) / √(0.00296) + (0.00226)
z(s) = ( 0.375 ) /0.072
z(s) = 5.21
Comparing z(s) and z(c) z(s) > z(c)
z(s) is in the rejection region for H₀ we reject H₀.
We have enough support to conclude that the two populations are different
b) folowing the same procedure now talking about non-contaminated chickens
Tyson Brand Chickens p₁ = 0,5 then q₁ = 0.5
Perdue Brand chickens p₂ = 0.25 then q₂ = 0.75
n₁ = n₂ = 80
Hypothesis Test:
Null Hypothesis H₀ p₁ = p₂
Alternative Hypothesis Hₐ p₁ ≠ p₂
Alternative hypothesis indicates a two-tail test
z(c) = 2.575
And z(s) = (0.5 - 0.25)/ √(0.5*0.5)/80 + (0.25*0.75)/80
z(s) = 0.25 / √( 0.003125 + 0.002343
z(s) = 0.25 / 0.0739
z(s) = 3.38
Comparing z(s) and z(c)
z(s) > z(c)
z(s) is in the rejection region so we reject H₀
The two population have different proportion of non-contaminated food

(Show full work please) Carter spots an airplane on radar that is currently approaching in a straight line, and
that will fly directly overhead. The plane maintains a constant altitude of 7250 feet.
Carter initially measures an angle of elevation of 16 to the plane at point A. At some
later time, he measures an angle of elevation of 26° to the plane at point B. Find the
distance the plane traveled from point A to point B. Round your answer to the
nearest foot if necessary
Answers
Consult the attached diagram.
In the larger triangle,
tan(16°) = (7250 ft) / (x + y)
and in the smaller triangle,
tan(26°) = (7250 ft) / y
You want to solve for x.
From the first equation (I'm ignoring units from here on, all distances are measured in ft), you have
(x + y) tan(16°) = 7250
x tan(16°) + y tan(16°) = 7250
x tan(16°) = 7250 - y tan(16°)
x = 7250 cot(16°) - y
From the second equation,
y = 7250 cot(26°)
Solving for x gives
x = 7250 cot(16°) - 7250 cot(26°)
x = 7250 (cot(16°) - cot(26°))
x ≈ 10,433 ft
The distance the plane traveled from point A to point B is 10,433 ft.
We have given that,
Carter spots an airplane on the radar that is currently approaching in a straight line, and that will fly directly overhead.

we have to solve for x.
From the first equation (I'm ignoring units from here on, all distances are measured in ft),
you have
(x + y) tan(16°) = 7250
x tan(16°) + y tan(16°) = 7250
x tan(16°) = 7250 - y tan(16°)
x = 7250 cot(16°) - y
From the second equation,
y = 7250 cot(26°)
Solving for x gives
x = 7250 cot(16°) - 7250 cot(26°)
x = 7250 (cot(16°) - cot(26°))x ≈ 10,433 ft
Therefore the distance the plane traveled from point A to point B is 10,433 ft.

However, the lab score is worth 23% of your total grade, each major test is worth 25%, and the final exam is worth 27%.

Answers
Answer:
72.7 is the weighted average score
Step-by-step explanation:
The weighted average score
= score of lab * % share of total grade + score of first major test * % share of total grade + score of second major test * % share of total grade + Score of the final exam * % share of total grade
Substituting the given values, we get -
0.23 * 74 + 0.25 * 69 + 0.25 * 62 + 0.27 * 85

camila is saving money to buy a 5 piece drum set that costs $360. She already has 80.00 saved and can earn the rest of the money by washing 20 cars. If m represents how much she earns for washing each car, which of the following equations can be solved to find how much Camila is paid for washing each car? Does anyone know
A. 20m -80 = 360
B. m(20+80) = 360
C. 360-80=20m
D. 80 + m= 360
Answers
The total cost of the drum set is $360 and she already has $80 saved. In order to calculate how much she still needed, you would need to subtract $80 from $360.
Amount needed = $360 - $80.
It tells you that she can earn the rest by washing 20 cars, and asks you to find how much she makes for washing each car. This would represent an unknown, which would be multiplied by 20 to equal the amount needed.
Money earned from washing cars = 20m.
Therefore, this equation can be represented by:
$360 - $80 = 20m.
