Answer:
181 pounds
Step-by-step explanation:
You have already got the equation and solution which is great! The next step is simply a matter of replacing "x" with "7", because you know x=7.
After doing this, you will be left with the equation 160+3*7=195-2*7. We will look at the first part of the equation first. Using the rules of BIDMAS, you can calculate 3*7=21 and then 160+21=181. 181 is your final answer.
You can check that this is right by calculating the second part of the equation, and once done you should be left with 181. Again, using BIDMAS, you need to do 2*7=14 then 195-14=181. Now we know that everything is correct.

A total of $8000 is invested: part at 5% and the remainder at 13%. How much is invested at each rate if the annual interest is $730?
Answers
Answer:
$3875 at 5%
$4125 at 13%
Step-by-step explanation:
Let x = amount invested at 5%.
Let y = amount invested at 13%.
x + y = 8000
0.05x + 0.13y = 730
Solve the first equation for x and sustitute into the second one to solve by the substitution method.
x = 8000 - y
0.05(8000 - y) + 0.13y = 730
400 - 0.05y + 0.13y = 730
0.08y = 330
y = 4125
x = 8000 - 4125
x = 3875

D. If she travels 20 miles, how long did she ski? This one is worked out backward, be careful!
show your work
Answers
Using the principle of direct variation, the solution to the problem given are :
5 miles per hour d = 5t15 miles 4 hoursGiven the Parameters :
Distance = d
Amount of time = t
d α t ; d = kt
We can find k = constant of proportionality = speed of travel ;
d = 10 miles ; t = 2 hours
10 = 2k
k = 10/2
k = 5
Hence, speed = 5 miles per hour
B.) The direct linear variation expression becomes ;
d = 5t
C.) Distance traveled in 3 hours :
t = 3 hours
d = 5t
d = 5(3) = 15 miles
D. Time taken to travel a distance of 20 miles
d = 5t
20 = 5t
t = 20/5
t = 4 hours
Therefore, it will take 4 hours to travel a distance of 20 miles.

The area of a square region is 529 mi2. What is the perimeter of the region?
Answers
Answer:
92 miles
Step-by-step explanation:
The area of a square is Length x Width. All sides of a square are equal in length so length = width. This is the same as saying x = length and x = width so X times X equals the area. X times X is X².
This tells you that X² = 529 mi². X would equal the square root of 529 which is 23. 23 x 23 = 529.
Each side of the square is 23 miles. The perimeter is equal to side 1 plus side 2 plus side 3 plus side 4. Again since it is a square all sides are equal.
This mean you can just take 4 x 23 miles. The perimeter = 92 miles
Answer:
The perimeter of the region is 92 miles
Step-by-step explanation:
For a given Square
Area = 529 mi²
Now, To find area we use formula
A = (l)²
529 = l²
√529 = l
23 = l
l = 23 miles
Now, To find perimeter of square we use,
P = 4l
P = 4 (23)
P = 92 miles
Thus, The perimeter of the region is 92 miles

Recibes un cierto embarque con la promesa de que no tiene más del 15% de ítems defectuosos. Si la proporción o porcentaje de ítems defectuosos es mayor queel15%,puedes solicitar una devolución. Tomas una muestra aleatoria de 10 ítems y encuentras 6ítems defectuosos. Ciertamente 6es más del 15% de la muestra.Presentas tu queja y te responden: el embarque tiene menos del 15% de ítems defectuosos. Si usted encontró 6 en su muestra, fue simplemente coincidencia o mala suerte, porque el embarque sí cumple con lo establecido.¿Cuál es la probabilidad de que realmente haya sido fruto de la coincidencia? ¿Cómo argumentarías para conseguir que te devuelvan el dinero?
Answers
Usando la distribución binomial, se encuentra que hay una probabilidad de 0.0012 = 0.12% que realmente haya sido fruto de la coincidencia. El argumento para conseguir que te devuelvan el dinero seria de que 6 ítems defectuosos es un resultado inusualmente alto.
Para cada ítem, solo hay dos resultados posibles. O está defectuoso o no lo es. La probabilidad de que un ítem sea defectuoso es independiente de cualquier otro ítem, lo que significa que se utiliza la distribución binomial para resolver esta cuestión.
Distribuición binomial:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Los parámetros son:
n es el número de ensayos.p es la probabilidad de éxito en un ensayo x es el número de éxitosLa media de la distribución binomial es:
[tex]E(X) = np[/tex]
La desviación estándar de la distribución binomial es:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Una medida se considera inusualmente alta si está más de 2.5 desviaciones estándar por encima de la media.
En este problema:
10 ítems, o sea, [tex]n = 10[/tex]15% defectuosos, o sea, [tex]p = 0.15[/tex].La probabilidad de que realmente haya sido fruto de la coincidencia es P(X = 6), o sea:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 6) = C_{10,6}.(0.15)^{6}.(0.85)^{4} = 0.0012[/tex]
Probabilidad de 0.0012 = 0.12% que realmente haya sido fruto de la coincidencia.
Para el argumento:
[tex]E(X) = np = 10(0.15) = 1.5[/tex]
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{10(0.15)(0.85)} = 1.13[/tex]
[tex]6 > 1.5 + 2(1.13)[/tex], o sea, el argumento para conseguir que te devuelvan el dinero seria de que 6 ítems defectuosos es un resultado inusualmente alto.

Answer:
∠A = 44°
Step-by-step explanation:
In order to find the measure of angle A, you need to know the value of the variable x. This means you need some relation that you can solve to find x.
Happily, that relation is "the sum of angles in a triangle is 180°." This means ...
84° +(x +59)° +(x +51)° = 180°
(2x + 194)° = 180° . . . collect terms
2x = -14 . . . . . . . . . . divide by °, and subtract 194
x = -7 . . . . . . . . . . . .divide by 2
Now, the measure of angle A is ...
∠A = (x +51)° = (-7 +51)°
∠A = 44°

At LaGuardia Airport for a certain nightly flight, the probability that it will rain is 0.07 and the probability that the flight will be delayed is 0.12. The probability that it will not rain the flight will leave on time is 0.87. What is the probability that it is raining if the flight has been delayed? Round your answer .
Answers
Probability of not raining and the flight leaving on time is equals to 0.320 .
De Morgan's law
P( A'∩ B') = P (A∪B)'
P (A∪B)' = 1 - P (A∪B)
P(A∪B) = P(A) + P(B) - P(A∩B)
According to the question,
Let Probability of rain = P(A)
= 0.07
Probability of flight delay =P(B) = 0.12
Therefore ,
Probability of rain and flight delay = P (A∩B)
= 0.87
Probability of not raining and flight on time = P( A'∩ B')
Substitute the values in the formula
P( A'∩ B') = 1 - [ 0.07 + 0.12 -0.87]
= 1- 0.68
= 0.32
= 0.320 ( nearest thousandth)
