Answer:

1.646%

Step-by-step explanation:

Sample size (n) = 2000

Sample Proportion p = 17% = 0.17

α = 0.95

Margin of Error :

Z(1-α)/2 * √((p*(1 - p)) /n)

Z(1 - 0.95/2) * √((0.17 * (1 - 0.17) / 2000)

Zscore = 1.96

1.96 * √(0.1411/2000)

1.96 * √0.00007055

1.96 * 0.0083994

Hence,

1.96 * 0.0083994

= 0.0164628

= 0.0164628 * 100%

= 1.646%

The margin of error for the random sample 2,000 driver's license applications is 1.646%.

The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.

It can be found out using the following formula.

[tex]MOE=Z_{\frac{\alpha}{2}}\times\left(\sqrt{p\times\dfrac{1-p}{n}}\right)[/tex]

Here, α is the level of significance, n is the sample size and p is the sample proportion.

A random sample of 2,000 driver's license applications found that 17% reported their eye color as blue.

Let level of significance is 0.05. At this level of significance the critical value of Z is 1.96. Put the values in the above formula as,

[tex]MOE=(1.96)\times\left(\sqrt{0.17\times\dfrac{1-0.17}{2000}}\right)\\MOE=0.01646\\MOE=1.646\%[/tex]

Thus, the margin of error for the random sample 2,000 driver's license applications is 1.646%.

Step-by-step explanation:

4x + 2x = 180

6x = 180

x = 30

Answer: 50

Step-by-step explanation:

Ok, we have the equation:

C=4000x-100x²+x³

Notice that the leading coefficient in this equation is positive, this means that as the value of x increases, also will the value of C.

Then we will not have a maximum, because as x →∞, C(x) →∞.

By doing an online search i found this same question, but with the change that we want to find x such that the average cost is minimum (this makes more sense).

Then let's do that:

The total cost for making x pieces is:

C(x) = 4000x-100x²+x³

Then the average cost, or the cost per piece, will be:

F(x) = C(x)/x = 4000 - 100*x + x^2

Notice that F(x) is a quadratic function with a positive leading coefficient, then the arms of the quadratic function will open upwards, this means that the minimum will be at the vertex.

To find the minimum, we must look at the zeros of the first derivation of F(x):

F'(x) = dF(x)/dx = -100 + 2*x

The zero is when:

F'(x) = 0 = -100 + 2*x

          100/2 = x

             50 = x

Then the number of x that minimizes the average cost is x = 50.

Using then given formula replace the letters with the given information.

28 to 42 means 28/42

We now reduce 28/42 to lowest terms.

28 ÷ 7 = 4

42 ÷ 7 = 6

We now have 4/6.

Inequalities

The  solution for the inequality:

[tex]\mid x+a\mid\ge b[/tex]

Can be expressed as:

[tex]x+a\ge b[/tex]

OR:

[tex]x+a\le -b[/tex]

Subtracting a to both inequalities:

[tex]x\ge b-a[/tex]

[tex]x\le -b-a[/tex]

Comparing to the given solutions, we have:

[tex]b-a=-1[/tex]

[tex]-b-a=-5[/tex]

Adding both equations:

[tex]-2a=-6[/tex]

Solving:

a=3

b=2

Answer:

15000

Step-by-step explanation

4x15=60

60x250=15000

The rate of the juice poured by the machine every minute is 10 liters.

The ratio of two numbers a and b can be written as a : b = a/b.

The ratio of two quantities is the unit rate of one quantity with respect to the other.

The total amount of juice poured by machine is 250 ml.

And, the time taken for that is 4 second.

In order to find the rate in liter per minute, convert the time in seconds to minutes and volume in liters as follows,

60 second = 1 minute

⇒ 1 second = 1/60 minute

⇒ 4 second = 4/160 = 1/40 minutes.

And, 1 liter = 1000 milliliter

⇒ 1 milliliter = 1/1000 liter

⇒ 250 milliliter = 250/ 1000 = 1/4 liter

Now, the rate of juice poured per minute is given as,

1/4 ÷ 1/40

⇒ 1/4 × 40

⇒ 10 liter per minute

Hence, the machine pour every minute 10 liter of juice.

#SPJ2

Answer:

y=mx+b is slope-intercept form

where m is the slope and b is the y intercept.

Since the line crosses the y axis at 0,0 the intercept is +0 or just nothing.

now all we need to do is find the slope

to do that just go from the y intercept (the first point) y units up and x units over untill u cross at the next point. for examples from (0, 0) to (1, 8)-the next point- i need to go up 8 units up and 1 unit over. this is described as rise over run and that is your slope 8/1 rise/run. rise is how many units i go up (or down) from the y intercept until the next point that lies on the line and run is how far i need to go over from how many units i just went up. If u continue to go 8 up and 1 over from each point u will see that u get a point lying of the line. This is why 8/1 is your slope

8/1 is the slope and 0,0 is your y intercept so we put nothing

the equation is y=8x

Step-by-step explanation:

Answer:

y=8x

Step-by-step explanation:

Pick two points (0,0) (2,16)

Then 16-0/2-0= 8

8 is the slope

The y intercept is 0 so

y=8x
