What's 95/300 in simplest form?

1 answer:

7 0

Answer is 19/60. The gcf of both numbers is 5. So divide both top and bottom by 5
95 divided by 5 is 19
300 divided by 5 is 60
19/60 can't be divided any further so that is the answer

Answer:

The 99% confidence interval for the proportion of readers who would like more coverage of local news is (0.3685, 0.4315).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

$n = 1600, \pi = 0.4$

99% confidence level

So $\alpha = 0.01$ , z is the value of Z that has a pvalue of $1 - \frac{0.01}{2} = 0.995$ , so $Z = 2.575$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4 - 2.575\sqrt{\frac{0.4*0.6}{1600}} = 0.3685$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.4 + 2.575\sqrt{\frac{0.4*0.6}{1600}} = 0.4315$

The 99% confidence interval for the proportion of readers who would like more coverage of local news is (0.3685, 0.4315).

(-0.75+6)-1(2.5x+-1.9

fenix001 [56]

Simplifying

(0.75x + 6) + -1(2.5x + -1.9) = 0

Reorder the terms:

(6 + 0.75x) + -1(2.5x + -1.9) = 0

Remove parenthesis around (6 + 0.75x)

6 + 0.75x + -1(2.5x + -1.9) = 0

Reorder the terms:

6 + 0.75x + -1(-1.9 + 2.5x) = 0

6 + 0.75x + (-1.9 * -1 + 2.5x * -1) = 0

6 + 0.75x + (1.9 + -2.5x) = 0

Reorder the terms:

6 + 1.9 + 0.75x + -2.5x = 0

Combine like terms: 6 + 1.9 = 7.9

7.9 + 0.75x + -2.5x = 0

Combine like terms: 0.75x + -2.5x = -1.75x

7.9 + -1.75x = 0

Solving

7.9 + -1.75x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7.9' to each side of the equation.

7.9 + -7.9 + -1.75x = 0 + -7.9

Combine like terms: 7.9 + -7.9 = 0.0

0.0 + -1.75x = 0 + -7.9

-1.75x = 0 + -7.9

Combine like terms: 0 + -7.9 = -7.9

-1.75x = -7.9

Divide each side by '-1.75'.

x = 4.514285714

Simplifying

x = 4.514285714

Car dealerships claim to make most of their money from servicing cars. In a certain month, an Acura dealership sold fifteen less

MA_775_DIABLO [31]

Answer:

New cars sold = 20,

Used cars sold = 25

Cars serviced = 290

Step-by-step explanation:

In a month they sold fifteen less used cars than twice the number of new cars.

Lets say 'x' number of new cars were sold, then:

The number of used car sold is:

$2\times x-15=2x-15$

In the same month they serviced fifty more than twelve times the number of new cars sold. So the number of cars serviced is:

$12\times x+50=12x+50$

Altogether they sold or serviced 335 cars, so the sum of all the cars sold and serviced should be 335:

$x+(2x-15)+(12x+15)=335$

Solving for 'x' we get:

$x+2x+12x-15+50=335$

$15x+35=335$

$15x=335-35=300$

$x=\frac{300}{15}=20$

Therefore, the number of new cars sold in that month is 20.

Number of used car sold $=2x-15=2\times 20-15=40-15=25$

Number of cars serviced $=12\times x+50=12\times20+50=240+50=290$

We can also cross check by summing them up:

$290+25+20=335$
