on Saturday a total of 1292 people went to the movies to see a new show there were four different showings for the new movie and the same number of people attended each showing how many people attended each showing​

In this Multiplication question, Multiplicar un número por 10 significa mover sus dígitos una posición a la izquierda en la escala decimal, añadiendo un cero al final.

Creo que tienes una pregunta sobre la multiplicación. Como no especificas qué estás multiplicando por 10, te proporcionaré un ejemplo general.

Si tienes el número 5 y lo multiplicas por 10, simplemente añades un cero al final para obtener 50. Esto se debe a que 10 es una 'decena', que es diez unidades en una.

Así, multiplicar cualquier número por 10 implica desplazar ese número una posición a la izquierda en nuestra escala decimal.

La regla general es que si se multiplica un número por 10, se añade un cero al final del número.

For the unknown number when I subtract 5 from my number, multiply that equality by 4 and then add 7 to the result, I get 35 is 12.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Let the unknown number be 'n' if I subtract 5 from my number, multiply that equality by 4, and then add 7 to the result, I get 35.

∴ 4(n - 5) + 7 = 35.

4n - 20 + 7 = 35.

4n = 48.

n = 48/4.

n = 12.

Answer:

x=41

Step-by-step explanation:

Final answer:

To find the missing side length in a right triangle, use the Pythagorean theorem. In this case, the missing side length is approximately 74.92.

Explanation:

To find the missing side length in a right triangle, you can use the Pythagorean theorem. The theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, we have one side length given as 36 and another side length given as 77. Let's label the missing side length as 'x'. Using the Pythagorean theorem, we can write the equation:

x^2 = 77^2 - 36^2

Solving this equation, we get x ≈ 74.92 (rounded to two decimal places).

The 90% confidence interval will be "(0.674, 0.748)".

Given:

Sample no. of events,

• x = 293

Sample size,

• n = 412

Now,

The sample proportion will be:

→

The significance level will be:

Form the z-table,

The critical value,

Now,

The standard error will be:

=

=

and,

The margin of error,

→

Now,

The lower limit will be:

=

=

The upper limit will be:

=

=

hence,

The CI is "(0.6744, 0.748)". Thus the response above is right.

Answer:

CI = (0.674, 0.748)

Step-by-step explanation:

The confidence interval of a proportion is:

CI = p ± SE × CV,

where p is the proportion, SE is the standard error, and CV is the critical value (either a t-score or a z-score).

We already know the proportion:

p = 293/412

p = 0.711

But we need to find the standard error and the critical value.

The standard error is:

SE = √(p (1 − p) / n)

SE = √(0.711 × (1 − 0.711) / 412)

SE = 0.0223

To find the critical value, we must first find the alpha level and the degrees of freedom.

The alpha level for a 90% confidence interval is:

α = (1 − 0.90) / 2 = 0.05

The degrees of freedom is one less than the sample size:

df = 412 − 1 = 411

Since df > 30, we can approximate this with a normal distribution.

If we look up the alpha level in a z score table or with a calculator, we find the z-score is 1.645.  That's our critical value.  CV = 1.645.

Now we can find the confidence interval:

CI = 0.711 ± 0.0223 * 1.645

CI = 0.711 ± 0.0367

CI = (0.674, 0.748)

So we are 90% confident that the proportion of adults connected to the internet from home is between 0.674 and 0.748.
