Answer:
7x + 35
Step-by-step explanation:
We can use the distributive property to simplify the equation and still make it equivalent.
Multiply each term in the (#) by the number outside the (#).
7(x + 5)
Becomes
7x + 7(5)
Which becomes
7x + 35.

A consulting firm has bid on two projects, A and B. The probability of landing A is 0.70. The probability of landing B is 0.60. The probability of landing both is 0.50.
What is the probability of landing A given it lands B?
Given:
The probability of landing A is 0.70.
The probability of landing B is 0.60.
The probability of landing both is 0.50.
To find:
The probability of landing A given it lands B.
Solution:
We have,
[tex]P(A) = 0.70[/tex]
[tex]P(B) = 0.60[/tex]
[tex]P(A\cap B) = 0.50[/tex]
The probability of landing A given it lands B is
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{P(A\cap B)}{P(B)}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{0.50}{0.60}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{5}{6}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=0.8333...[/tex]
[tex]P\left(\dfrac{A}{B}\right)\approx 0.83[/tex]
Therefore, the probability of landing A given it lands B is about 0.83.

How do I write “3 is less than a number”?
Answer:
3 - x
Step-by-step explanation:
Just think in order in bits.
3
So, write 3.
Less than = subtraction
So, write a subtraction symbol.
A number = a variable, such as x.
So, write a variable.
That will give you: 3 - x
The question is in the picture down below!
25 degrees
35 degrees
45 degrees
55 degrees
Answer:
35°
Step-by-step explanation:
Complementary angles has a sum of 90°
m<A + m<B = 90°
2x + 23 + 4x -29 = 90° add like terms
6x - 6 = 90° add 6 to both sides
6x = 96 divide both sides by 6
x = 16 now replace the x in m<B = 4x - 29 with 16
4×16 - 29 = 35
solve 2x = 1/32

how do you calculate the standard error of the mean in SPSS?
Answer:
Hope this helps
Step-by-step explanation:
Std Error Mean – Standard Error Mean is the estimated standard deviation of the sample mean. This value is estimated as the standard deviation of one sample divided by the square root of sample size: 9.47859/sqrt(200) = . 67024, 10.25294/sqrt(200) = . 72499.

To find:
The simplified form of the given expression.
Solution:
We have,
[tex]\log_59+\log_521-\log_57[/tex]
It can be written as
[tex]=\log_5(9\times 21)-\log_57[/tex] [tex][\because \log_ax+\log_ay=log_a(xy)][/tex]
[tex]=\log_5\dfrac{9\times 21}{7}[/tex] [tex][\because \log_ax-\log_ay=log_a\dfrac{x}{y}][/tex]
[tex]=\log_5(9\times 3)[/tex]
[tex]=\log_527[/tex]
Therefore, the simplified form of the given expression is [tex]\log_527[/tex].

Factorise 12u-uv please help lol
Answer:
u(12-v)
Step-by-step explanation:
12u and -uv both have a factor of u in common, so we can pull it out to give us the factored expression u(12-v).
Note on factoring:
Remember, it's just using the distributive property in reverse! We can get our original expression back by distributing the u to the 12 and the -v.

A researcher in sports equipment is investigating the design of racing swimsuits for women. The researcher selected a sample of 40 women swimmers from high school swim teams in the state and randomly assigned each swimmer to one of two groups: suit A or suit B. The women will wear the assigned suits for a certain race, and the mean swim times for each group will be recorded. The difference in the sample mean swim times will be calculated. Which of the following is the appropriate inference procedure for analyzing the results?
A. A two-sample t-interval for a difference between sample means
B. A two-sample t-interval for a difference between population means
C. A one-sample t-interval for a sample mean
D. A one-sample t-interval for a population mean
E. A matched pairs t-interval for a mean difference
Answer:
B. A two-sample t-interval for a difference between population means
Step-by-step explanation:
in the given situation we are comparing the groups that are independent also we test the difference of the population mean so here consider inference procedure for analyzing the results is that there should be two sample t -interval by taking a difference between the population means
hence, the correct option is B.
¿CÓMO ALCANZÓ EL HOMBRE EL CONCEPTO DE INFINITO?
Trabajar con el infinito es un asunto complicado. Las paradojas de Zenón alertaron por primera vez a los filósofos occidentales sobre esto en 450 a. C. cuando argumentó que un corredor rápido como Aquiles tiene un número infinito de lugares para alcanzar durante la persecución de un corredor más lento. Desde entonces, ha habido una lucha por entender cómo usar la noción de infinito de una manera coherente. Este artículo se refiere al importante y controvertido papel que juegan los conceptos de infinito y el infinito en las disciplinas de la filosofía, las ciencias físicas y las matemáticas.
Los filósofos quieren saber si hay más de un concepto coherente de infinito; qué entidades y propiedades son infinitamente grandes, infinitamente pequeñas, infinitamente divisibles e infinitamente numerosas; y qué argumentos pueden justificar las respuestas de una forma u otra.
Aquí hay algunos ejemplos de estas cuatro formas diferentes de ser infinito. La densidad de la materia en el centro de un agujero negro es infinitamente grande. Un electrón es infinitamente pequeño. Una hora es infinitamente divisible. Los números enteros son infinitamente numerosos. Estas cuatro afirmaciones están ordenadas de mayor a menor controversia, aunque las cuatro han sido cuestionadas en la literatura filosófica.
Este artículo también explora una variedad de otras preguntas sobre el infinito. ¿Es el infinito algo indefinido e incompleto, o es completo y definido? ¿Qué quiso decir Tomás de Aquino cuando dijo que Dios es infinitamente poderoso? ¿Estaba en lo cierto Gauss, que fue uno de los más grandes matemáticos de todos los tiempos, cuando hizo la controvertida observación de que las teorías científicas involucran infinitos simplemente como idealizaciones y simplemente para facilitar la aplicación de esas teorías, cuando en realidad todas las entidades físicamente reales son ¿finito? ¿Cómo cambió la invención de la teoría de conjuntos el significado del término "infinito"? ¿Qué quiso decir Cantor cuando dijo que algunos infinitos son más pequeños que otros? Quine dijo que los primeros tres tamaños de los infinitos de Cantor son los únicos en los que tenemos motivos para creer. Los platónicos matemáticos no están de acuerdo con Quine. ¿Quién tiene razón? Veremos que existen profundas conexiones entre todas estas cuestiones.

Step-by-step explanation:
Apply trigonometric function to find the height (h) of the wall.
Reference angle = 40°
Hypotenuse = 17 ft
Adjacent = h (height of the wall)
Apply CAH:
Cos 40 = Adj/Hyp
Cos 40 = h/17
17*Cos 40 = h

Answer:
(20×20)+(2×20×30)
400+1200
1600inches^2
Answer:
1600 in^2
Step-by-step explanation:
We only have to add the areas of one square in the centre and 4 surrounding triangles.
area of the square=20×20=400 in^2
area of one triangle=1/2×20×30=300 in^2
area of four triangles=4×300=1200 in^2
So, total surface area of the square pyramid=400+1200=1600 in^2
