Step-by-step explanation:
This is more of analyzing a graph rather than a word problem.
We are told that 4 pm is at 16 hrs after midnight. You can see that the graph increases up to 4 pm. We can say 1 is correct.
After 6 pm at 18 hrs, we can see that the graph decreases. We can say 3 is correct.
Looking at the slope of the graph, 12 to 16 has a steeper slope than 8 to 12. We can say the temperature increases faster at 12 to 16 than 8 to 12.

Answer:
[tex]\dfrac{9}{35}[/tex] is the fraction of 8th graders who are boys.
Step-by-step explanation:
Let total number of 8th graders = [tex]x[/tex]
Given that, [tex]\frac{3}{7}[/tex] of 8th graders play sports
[tex]\Rightarrow[/tex] 8th graders who play sports = [tex]\frac{3}{7} \times x[/tex]
Also, Given that, [tex]\frac{3}{5}[/tex] of 8th graders that play sports are boys
Number of 8th graders that play sports, and are boys = [tex]\frac{3}{5} \times \text{Number of 8th graders who play sports}[/tex]
[tex]\Rightarrow \dfrac{3}{5} \times \dfrac{3}{7} \times x\\\Rightarrow \dfrac{9}{35} \times x[/tex]
Hence, the answer is:
[tex]\dfrac{9}{35}[/tex] is the fraction of 8th graders who are boys.
which points are separated by distance of 6 units?
A. (5,6) (4,6)
B. (1,3) (6,3)
C. (8,1) (1,1)
D. (7,2) (1,2)
Option (D) points (7,2) (1,2) are separated by distance of 6 units.
What is distance between two points?It is the length of the straight line connecting these points in the coordinate plane. This distance can never be negative, therefore we take the absolute value while finding the distance between two given points. The distance formula is an application of the Pythagorean theorem.
For the given situation,
The distance between the two points must be 6 units.
Let the points be (x1,y1) and (x2,y2)
The distance formula is
[tex]d=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2} }[/tex]
We need to check all the options.
Option A: (x1,y1) = (5,6), (x2,y2) = (4,6)
⇒ [tex]d=\sqrt{(4-5)^{2} +(6-6)^{2} }[/tex]
⇒ [tex]d=\sqrt{(-1)^{2} +(0)^{2} }[/tex]
⇒ [tex]d=\sqrt{1}[/tex]
⇒ [tex]d=1[/tex]
Distance ≠ 6. So option A is incorrect.
Option B: (x1,y1) = (1,3), (x2,y2) = (6,3)
⇒ [tex]d=\sqrt{(6-1)^{2} +(3-3)^{2} }[/tex]
⇒ [tex]d=\sqrt{(5)^{2} +(0)^{2} }[/tex]
⇒ [tex]d=\sqrt{25}[/tex]
⇒ [tex]d=5[/tex]
Distance ≠ 6. So option B is incorrect.
Option C: (x1,y1) = (8,1) , (x2,y2) = (1,1)
⇒ [tex]d=\sqrt{(1-8)^{2} +(1-1)^{2} }[/tex]
⇒ [tex]d=\sqrt{(-7)^{2} +(0)^{2} }[/tex]
⇒ [tex]d=\sqrt{49}[/tex]
⇒ [tex]d=7[/tex]
Distance ≠ 6. So option C is incorrect.
Option D: (x1,y1) = (7,2) , (x2,y2) = (1,2)
⇒ [tex]d=\sqrt{(1-7)^{2} +(2-2)^{2} }[/tex]
⇒ [tex]d=\sqrt{(-6)^{2} +(0)^{2} }[/tex]
⇒ [tex]d=\sqrt{36}[/tex]
⇒ [tex]d=6[/tex]
Distance = 6. So option D is correct.
Hence we can conclude that option (D) points (7,2) (1,2) are separated by distance of 6 units.

find the center and radius of the circle: (x+9)^2+(y-6)^2=25
Answer:
The center is (-9,6) and the radius is 5
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2+(y-k)^2=r^2
where (h,k) is the center and r is the radius
(x - -9)^2+(y-6)^2=5^2
The center is (-9,6) and the radius is 5
Circle equation: (x - h)^2 + (y - k)^2 = r^2
(h, k) is the center.
r is the radius.
(h, k) in the given equation is (-9, 6). This is the center.
We need to take the square root of 25 since the formula has r^2.
√25 = 5
So, the radius is 5.

H(4 1/2, -3 1/4) x (3 3/4, -1 3/4) what the midpoint of hx
Answer:
(3 7/8, 2 3/4)
Step-by-step explanation:
To find the midpoint, the formula is (x1-x2)/2 and (y1-y2)/2. So, in this case, our x1 is 4 1/2 and our x2 is -3 1/4. Subtract x2 from x1 and you will get 7 3/4. Then, divide by 2 to get 3 7/8. This is our x-coordinate.
Our y1 is 3 3/4 and our y2 is -1 3/4. Subtract y2 from y1 to get 5 1/2. Then divide by two to get 2 3/4. This is our y-coordinate.
Now we have our x and y coordinates.

Step-by-step explanation:
The equation of the circle is (x + 1)² + (y + 3)² = 6². When we plug in (-6, -6) we get (-6 + 1)² + (-6 + 3)² = 6², which is a true statement so that means that the point is on the circle.
On the coordinate plane shown, each grid unit represents 10 feet. Polygon QRST has vertices Q(20, 30), R(−10, 30), S(−10, −20), and T(20, −20), and represents the floor plan of a room. Find the perimeter and area of the room.
The coordinate plane is missing, so i have attached it.
Answer:
Perimeter of room = 140 ft
Area of room = 1200 sq.ft
Step-by-step explanation:
From the cordinate plane attached, we can see the polygon QRST which represents the floor plan of the roo.
Thus;
The length of the sides of the room are;
ST = RQ = 30
QT = RS = 40
Perimeter of a rectangle is the sum of all sides of the rectangle.
Thus, perimeter of the room = (30 × 2) + (40 × 2) = 140 ft
Now, area of a rectangle is the product of two perpendicular sides.
Thus area of room = 40 x 30 = 1200 sq.ft

Answer:
(A)a translation 5 units down and 2 units to the right followed by a reflection across the y-axis
Step-by-step explanation:
If a point is reflected across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite.
Triangle LMN has points (2, 1), (1, 1), (1, 3).
Triangle L'M'N' has points (-4,-4), (-3,-4), (-3,-2).
From the given options:
Option A: A translation 5 units down and 2 units to the right followed by a reflection across the y-axis
Given the points: (2, 1), (1, 1), (1, 3) of Triangle LMN
A translation 5 units down(x,y-5): (2,-4), (1,-4), (1,-2)2 units to the right(x+2, y-5): (4, -4), (3, -4), (3, -2)Reflection across the y-axis: (-4,-4), (-3,-4), (-3,-2)Therefore, the sequence of transformation in Option A produces Triangle L'M'N'.

In the distribution, the first quartile,median and mean are 30.8,48.5 and 42.0 respectively. If the co efficient skewness is -0.38, find the third quartile?
Answer:
The third quartile is 56.45
Step-by-step explanation:
The given parameters are;
The first quartile, Q₁ = 30.8
The median or second quartile, Q₂ = 48.5
The mean, [tex]\bar x[/tex] = 42.0
Coefficient of skewness = -0.38
The Bowley's coefficient of skewness (SK) is given as follows;
[tex]SK = \dfrac{Q_3 + Q_1 - 2 \times Q_2}{Q_3 - Q_1}[/tex]
Plugging in the values, we have;
[tex]-0.38 = \dfrac{Q_3 + 30.8 - 2 \times 48.5}{Q_3 - 30.8}[/tex]
Which gives;
-0.38×(Q₃ - 30.8) = Q₃ + 30.8 - 2 × 48.5
11.704 - 0.38·Q₃ = Q₃ - 66.2
1.38·Q₃ = 11.704 + 66.2 = 77.904
Q₃ = 56.45
The third quartile = 56.45.

Answer:
The balance in 2020 is $47,810,662.65576
Step-by-step explanation:
In order to find the balance in 2020, first we would have to calculate the number of year as follows:
number of years, t=2020-1626
number of years, t=394
Therefore, to calculate the balance in 2020, we would have to use the following formula:
f(t)= 24(1.0375)∧394
f(t)=24*1,992,110.94399
f(t)=$47,810,662.65576
The balance in 2020 is $47,810,662.65576

3. A telephone pole is supported by two wires on opposite sides. At the top of the pole, the wires
form an angle of 55º. On the ground, the ends of the wires are 11.0 m apart. One wire makes a
(4) 41° angle with the ground.
a) How long is each wire? (round to the nearest tenth)
b) How tall is the pole? (round to the nearest tenth)
I understand A, but please help with B ASAP!!!!
Answer: a) length of the wires are 8.1m and 13.4m
b) length of pole is 8.8m
Step-by-step explanation:
The diagram representing the scenario is shown in the attached photo. Triangle ABC is formed. Since the sum of the angles in a triangle is 180°, it means that angle B would be
180 - (41 + 55) = 84°
a) AC and BC are the lengths of each wire.
CD is the height of the pole
To determine AC, we would apply sine rule which is expressed as
a/SinA = b/SinB = c/SinC
Therefore,
11/Sin55 = BC/Sin 41 = AC/Sin84
1) 11//Sin 55 = BC/Sin 41
Cross multiplying, it becomes
11Sin41 = BCSin55
11 × 0.6561 = BC × 0.8192
BC = 7.2171/0.8192 = 8.8m
2) 11/Sin55 = BC/Sin 41 = AC/Sin84
1) 11//Sin 55 = AC/Sin 84
Cross multiplying, it becomes
11Sin84 = ACSin55
11 × 0.9945 = AC × 0.8192
AC = 10.9395/0.8192
AC = 13.4m
b) triangles ACD and BCD are right angle triangles. To determine CD, we would apply the sine trigonometric ratio.
Sin # = opposite side/adjacent side
Considering triangle ACD,
Sin 41 = CD/13.4
CD = 13.4Sin41 = 13.35 × 0.6561
CD = 8.8m

Bety compró 16 pares de calcetas, entre blancas y negras, y pagó $339. Los pares de calcetas blancas cuestan $24 y las negras $19. Plantea el sistema de ecuaciones y resuelve por el método que creas conveniente. Después toma foto y súbela en donde se indica.
Answer:
Sistema de ecuaciones:
x+y= 16
24x+19y=339
Respuesta:
x=7, y=9
Step-by-step explanation:
Con la información del enunciado puedes plantear las siguientes ecuaciones:
x= cantidad de calcetas blancas
y= cantidad de calcetas negras
x+y= 16 (1)
24x+19y=339 (2)
Para resolver las ecuaciones, debes iniciar despejando x en 1:
y=16-x (3)
Después, debes reemplazar (3) en (2) y despejar x para encontrar su valor:
24x+19(16-x)=339
24x+304-19x=339
5x=339-304
x=35/5
x=7
Luego, puedes reemplazar el valor de x en (3) para encontrar y:
y=16-x
y=16-7
y=9
De acuerdo a esto, x= 7, y=9.
