Sabemos que

el costo del televisor es -------> 130000

si se pago (1/4) al contado-------> (1/4)*130000=32500 
quedo pendiente por pagar------> 130000-32500=97500

la cantidad pendiente por pagar se divide en 6 giros
97500/6=16250

La respuesta es
el valor de cada giro sera de 16250

densk [106]

Answer:

The probability of getting a sample with 80% satisfied customers or less is 0.0125.

Step-by-step explanation:

We are given that the results of 1000 simulations, each simulating a sample of 80 customers, assuming there are 90 percent satisfied customers.

Let \hat p = <u><em>sample proportion of satisfied customers</em></u>

The z-score probability distribution for the sample proportion is given by;

                                Z  =  \frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }  ~ N(0,1)

where, p = population proportion of satisfied customers = 90%

            n = sample of customers = 80

Now, the probability of getting a sample with 80% satisfied customers or less is given by = P( \hat p \leq 80%)

  P( \hat p \leq 80%) = P( \frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } } \leq \frac{0.80-0.90}{\sqrt{\frac{0.80(1-0.80)}{80} } } ) = P(Z \leq -2.24) = 1 - P(Z < 2.24)

                                                                  = 1 - 0.9875 = <u>0.0125</u>

The above probability is calculated by looking at the value of x = 2.24 in the z table which has an area of 0.9875.

zhuklara [117]

Answer:

27.19% probability that a female driver was involved in an accident

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

74,250 car accidents. Of those, in 20,187, the driver was a female.

Based on this, what is the probability that a female driver was involved in an accident?

p = 20187/74250 = 0.2719

27.19% probability that a female driver was involved in an accident

On commencing employment a man is paid a salary of $7200 per annum and receives annual increments of $350. Determine his salary
Marina CMI [18]

Answer:

Step-by-step explanation:

From the question, we can form an equation like: S = 7200 + 350X

where S is the salary and X is year.

1. His salary in the 9th year, means X=9, so we substitute 9 into the equation to find S = 7200 +350 (9) = 10350

2. The total he will have in the first 12years, we have:

Sum of first n terms of an <em><u>AP: S =(n/2)[2a + (n- 1)d]</u></em> where a is the value of the 1st term, here a is 7200 and d = 350 the common difference between terms

=> S = (12/2)[2*7200 + (12- 1)350] = 109500

The graph of which function passes through (0,3) and has an amplitude of 3? f (x) = sine (x) + 3 f (x) = cosine (x) + 3 f (x) =
Cloud [144]

Answer:

f(x)=3*cosine(x)

Step-by-step explanation:

We are looking for a trigonometric function which contains the point (0, 3), and has an amplitude of 3.

We know that for a sine function f(x)=sin(x), f(0)= 0; therefore the function we a looking for cannot be a sine function because it is zero at x=0.

However, the cosine function f(x)=cos(x) gives non-zero value at x=0:

f(0)=cos(0)=1

therefore, a cosine function can be our function.

Now, cosine function with amplitude a has the form

f(x)=a*cos(x)

this is because the cosine function is maximum at x= 0 and therefore, has the property that

f(0)=a*cos(0)= a

in other words it contains the point (0, a).

The function we are looking for contains the point (0, 3); therefore, its amplitude must be 3, or

f(x)=3cos(x)

we see that this function satisfies our conditions: f(x) has amplitude of 3, and it passes through the point (0, 3) because f(0)=3
