the formula d= rt gives the distance traveled in time t at rate r. A bicyclist rides for 1.5 hours and travels 25 miles. what is the average rate of speed?

A. 26.5 miles per hour
B. 16.7 miles per hour
C. 23.5 miles per hour
D. 37.5 miles per hour

Answers

16.7 miles per hour
This is because d=rt so r=d/t
25/1.5 = 16.7

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

25 miles = r x 1.5 hours

To find r divide both sides by 1.5:

R = 25/1.5

R = 16.7 miles per hour

The answer would be B.

A random sample of 2,000 driver's license applications found that 17% reported their eye color as blue. What is the margin of error for the sample? Round to the nearest tenth of a percent.

Answers

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%.

What is margin of error?

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%.

a)Triangle ABC is a scaled copy of triangle DEF with what scale factor?

b)Triangle DEF is a scaled copy of triangle ABC with what scale factor?

Answers

Answer:

a) 3/2 or 1.5

b) 2/3 or ≈.66

Step-by-step explanation:

AB corresponds to DE because they are both the longest sides of their respective triangles.

a) The scale factor would be what you would multiply 8 by to get 12. 12/8 is 3/2 or 1.5

b) The scale factor would be what you multiply 12 by to get 8. 8/12 is 2/3 or ≈.66

The total cost of production of spare parts of computer is given as C=4000x-100x²+x³ where x is the number of units of spare parts produced so that the average cost will be maximum?

Answers

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.

Hey could you help me with this: A machine pours 250 millilitres of juice every 4 seconds. How many litres of juice does the machine pour every minute?`​

Answers

Answer:

15000

Step-by-step explanation

4x15=60

60x250=15000

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

What is the ratio of two numbers?

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.
