Answer:
Mean and Median
Step-by-step explanation:
Given the data :
285,288,289,290,299,300,308,309,312,314
To summarize the data using a measure of centre, considering that the dataset doesn't show a great deal of variation we could use either the mean or median value.
The mean, x = Σx / n
n = sample size = 10
Σx = 2994 ; n = 10
x = 2994 / 10 = 299.4
Also the median value ;
1/2 * (n + 1)th term
1/2 * (10 + 1)th term
1/2 * 11
= 5.5 th term
= (5 + 6)th / 2
= (299 + 300) / 2
= 299.5
Molly is using a map with a scale of 12 = 40 molly needs to travel from point x to point y how far does she need to travel
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Ratio=12:40[/tex]
Required
Determine the actual distance between x and y
The question is incomplete, as the scale distance between x and y is not given.
To solve this, we make assumptions.
A scale measurement is represented as:
[tex]Ratio = Scale : Actual[/tex]
So, we have:
[tex]Scale : Actual = 12 : 40[/tex]
Express as fraction
[tex]\frac{Actual}{Scale} = \frac{40}{12}[/tex]
Make Actual, the subject
[tex]Actual = \frac{40}{12} * Scale[/tex]
Now, assume that the distance between x and y is 60 (on the scale), the actual distance traveled will be:
[tex]Actual = \frac{40}{12} * 60[/tex]
[tex]Actual = 200[/tex]

Find the area of the trapezoid
Answer: 1. 54, 2. 48
Step-by-step explanation: To find the area of a trapezoid you add the top base and the bottom base then divide them by two, and multiply them by the height.For #1. 8+10/2= 9 then 9x6=54 For #2. 4+12/2=8 then 8 x 6=48.
Answer:
Figure it out using this: Area= 1/2(Base 1 + Base 2) x Height
Bases are the tops and bottoms of the trapezoids

a city-wide gardening club is up of men, women and children in the ratio 5:4:11.
altogether there are are 2240 members of the gardening club how many members of the gardening club are : 1) women 2) men 3) children
Answer:
Women: 448 Men: 560 Children: 1232
Step-by-step explanation:
5+4+11 = 20/2240 = 112
Women = 4 x 112 = 448
Men = 5 x 112 = 560
Children = 11 x 112 = 1232
Total = 1232 + 560 +448 = 2240

Answer:
the slope is 3/2
Step-by-step explanation:
Answer:
1.5
Explanation:
the slope of the line can be calculated by rise ÷ run, or the vertical increase divided by the horizontal increase. we can see that from the point (1,-3) to the point (3,0), the line increases vertically by 3 and horizontally by 2.
since the line is moving upwards, it is positive.
thus, the slope of the line is 3 ÷ 2 = 1.5.
no files plssssssss!
Answer:
Your answer is the first option, (2,-1).
Step-by-step explanation:
All you have to do is plug the (x,y) values into both equations, then solve and see if they're true.
For the first equation, plug x (aka 2) and y (aka -1) into the places they belong.
2x + y = 3 would become 2(2) + (-1) = 3 after putting the values in the right spots.
Solve.
2(2) = 4.
4 + (-1) = 3
3 = 3.
That means that (2,-1) is the solution for the first equation, however it also needs to be true for the second. Do the same thing and plug the values in their designated spots.
y = x - 3 will become -1 = 2 - 3.
2 - 3 = -1.
So you're left with:
-1 = -1, which means again that (2,-1) is also the solution for that equation.

"la temperatura mas baja conocida en la tierra es de 273° bajo cero mientras que la temperatura promedio de la superficie de la tierra es de 37 calcula la variacion de la temperatura"
Answer:
Variación de temperatura: 310°C
Step-by-step explanation:
La variación de temperatura entre la temperatura más baja conocida en la tierra (-273°C = 273° bajo cero) y la temperatura promedio de la tierra (37°C) será el valor absoluto de la diferencia de estos dos valores, es decir:
Variación de temperatura: |-273°C - 37°C|
Variación de temperatura: |-310°C|
Como el valor absoluto de un número negativo es su valor positivo (|-x| = x)
Variación de temperatura: 310°CA ship travels due west for 83 miles . It then travels in northwest direction for 111 miles and ends up 165 miles from its original position. To the nearest tenth of a degree how many degrees north of west did it turn when it changed direction? Show your work.
*see attachment for the diagram of the information given
Answer:
115.8°
Step-by-step explanation:
Due west = 83 miles
Northwest = 111 miles
Distance to its original position = 165 miles
Let x represent the degree north of west that it turned when it changed direction which is the opposite angle of 165 miles.
Thus, to find x, we'd apply the Law of Cosine which is given as:
c² = a² + b² - 2ab*cos C
Where,
C = x
a = 83 miles
b = 111 miles
c = 165 miles
Plug in the values
165² = 83² + 111² - 2*83*111*Cos x
27,225 = 19,210 - 18,426*Cos x
27,225 - 19,210 = - 18,426*Cos x
8,015 = -18,426*Cos x
8,015 = -18,426*Cos x
8,015/-18,426 = Cos x
-0.434983176 = Cos Cmx
Cos x = -0.434983176
x = cos^{-1}(-0.434983176)
x = 115.784223°
x = 115.8°

An expression is shown below:
4(m + 3 + 5m)
Part A: Write two expressions that are equivalent to the given expression. (3 points)
Part B: Show that one of your expressions in Part A is equivalent to the given expression using algebraic properties. Explain which properties you used. (4 points)
Part C: Show that your other expression from Part A is equivalent to the given expression by substituting a number for m. (3 points)
Answer:
24m + 12 - - - (1)
12(2m + 1) - - - (2)
Step-by-step explanation:
Given the expression :
4(m + 3 + 5m)
Equivalent expressions include :
24m + 12 - - - (1)
12(2m + 1) - - - (2)
Using algebaraic properties :
4(m + 3 + 5m)
We can expand :
4m + 12 + 20m
4m + 20m + 12
24m + 12
Hence,
4(m + 3 + 5m) = 24m + 12
Using Substitution:
Let m = 5
4(m + 3 + 5m)
4(5 + 3 + 5(5))
4(5 +3 + 25)
4(33)
= 132
12(2m + 1)
12(2(5) + 1)
12(10 + 1)
12(11)
= 132

Don Alfredo quiete construir un corral cuadrado para sus gallinas, utizando metros de malla lineal para redearlo. Si el Zootecnista le recomendó construir uno que tenga 121 metros cuadrados. ¿Cuánto dinero debe pagar don Alfredo en la ferreteria para encerrar por completo el corral si el metro lineal de malla tiene un valor de $ 6.200 el metro?
Answer:
Don Alfredo debe pagar $272,200 para encerrar por completo el corral.
Step-by-step explanation:
Dado que Don Alfredo quiere construir un corral cuadrado para sus gallinas, utilizando metros de malla lineal para rodearlo, si el zootecnista le recomendó construir uno que tenga 121 metros cuadrados, para determinar cuánto dinero debe pagar don Alfredo en la ferretería para encerrar por completo el corral si el metro lineal de malla tiene un valor de $ 6.200 el metro se deben realizar los siguientes cálculos:
121 metros cuadrados = √121 = 11 (x 11) = 11 x 4 = 44 metros lineales
44 x 6,200 = X
272,800 = X
Por lo tanto, Don Alfredo debe pagar $272,200 para encerrar por completo el corral.

Write the trigonometric expression in terms of sine and cosine, and then simplify. cot()/sin()-csc()
Answer:
First, we know that:
cot(x) = cos(x)/sin(x)
csc(x) = 1/sin(x)
I can't know for sure what is the exact equation, so I will assume two cases.
The first case is if the equation is:
[tex]\frac{cot(x)}{sin(x)} - csc(x)[/tex]
if we replace cot(x) and csc(x) we get:
[tex]\frac{cot(x)}{sin(x)} - csc(x) = \frac{cos(x)}{sin(x)} \frac{1}{sin(x)} - \frac{1}{sin(x)}[/tex]
Now let's we can rewrite this as:
[tex]\frac{cos(x)}{sin(x)} \frac{1}{sin(x)} - \frac{1}{sin(x)} =\frac{cos(x)}{sin^2(x)} - \frac{1}{sin(x)}[/tex]
[tex]\frac{cos(x)}{sin^2(x)} - \frac{sin(x)}{sin^2(x)} = \frac{cos(x) - sin(x)}{sin^2(x)}[/tex]
We can't simplify it more.
Second case:
If the initial equation was
[tex]\frac{cot(x)}{sin(x) - csc(x)}[/tex]
Then if we replace cot(x) and csc(x)
[tex]\frac{cos(x)}{sin(x)}*\frac{1}{sin(x) - 1/sin(x)} = \frac{cos(x)}{sin(x)}*\frac{1}{sin^2(x)/sin(x) - 1/sin(x)}[/tex]
This is equal to:
[tex]\frac{cos(x)}{sin(x)}*\frac{sin(x)}{sin^2(x) - 1}[/tex]
And we know that:
sin^2(x) + cos^2(x) = 1
Then:
sin^2(x) - 1 = -cos^2(x)
So we can replace that in our equation:
[tex]\frac{cos(x)}{sin(x)}*\frac{sin(x)}{sin^2(x) - 1} = \frac{cos(x)}{sin(x)}*\frac{sin(x)}{-cos^2(x)} = -\frac{cos(x)}{cos^2(x)}*\frac{sin(x)}{sin(x)} = - \frac{1}{cos(x)}[/tex]
