I could really use some help answering a few questions

​

Answer:

$ 1100

Step-by-step explanation:

Let p(x) be the price he charges for a car after x price reductions.

Since car costs him $10,000, and fixed costs are $1000

p(x) = 13000-10000-1000-300x = 2000 - 300x

Let  q(x) = 12 + 2x the quantity of cars sold after x price reductions.

and the profit he can make are given by:

Profit = R(x) = (12+2x)(13,000 - 10,000 - 1,000 - 300x) dollars.

As you can see, maximizing profit , we have to check where P'(x) = 0

And P''(x)<0.

So we get x = 3.

Replacing the value we get we get 2000 - 300 X 3 = 2000 - 900

                                                                 = $ 1100

Answer:

The prime factorization of 200 using exponential notation is [tex]2^{3}\times 5^{2}[/tex].

Step-by-step explanation:

First, we decompose the number given on statement by applying prime numbers in ascending order. We see that 200 is an even number, therefore, we infer that smallest prime number within is 2.

1) [tex]\frac{200}{2} = 100[/tex] (Even number)

2) [tex]\frac{100}{2} = 50[/tex] (Even number)

3) [tex]\frac{50}{2} = 25[/tex] (Even number)

4) [tex]\frac{25}{5} = 5[/tex] (Odd number, not a multiple of 3, but a multiple of 5 since last digit is 5)

5) [tex]\frac{5}{5} = 1[/tex] (Odd number, not a multiple of 3, but a multiple of 5 since last digit is 5)

Now, we construct the prime factorization using exponential notation:

[tex]200 = 2^{3}\times 5^{2}[/tex]

The prime factorization of 200 using exponential notation is [tex]2^{3}\times 5^{2}[/tex].

Answer:

b= 7

Step-by-step explanation:

here's your solution

=> perimeter of rectangle = 62 cm

=> length = 24 cm

=> let width be (b)

=> perimeter of rectangle = 2(l + b)

=> 2(l + b ) = 62

=> 2(24 + b) = 62

=> 48 +2b = 62

=> 2b = 62 - 48

=> 2b = 14

=> b = 14/2

=> b = 7

Answer:

The 90% confidence interval for the true population of Americans with asparagus anosmia is (0.5926, 0.6120).

Step-by-step explanation:

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

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

Researchers contacted 6909 participants in a large scientific cohort and found that 4161 had asparagus anosmia.

This means that [tex]n = 6909, \pi = \frac{4161}{6909} = 0.6023[/tex]

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

The lower limit of this interval is:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6023 - 1.645\sqrt{\frac{0.6023*0.3977}{6906}} = 0.5926[/tex]

The upper limit of this interval is:

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6023 + 1.645\sqrt{\frac{0.6023*0.3977}{6906}} = 0.6120[/tex]

The 90% confidence interval for the true population of Americans with asparagus anosmia is (0.5926, 0.6120).

Answer:

102cm³

Step-by-step explanation:

Imagine the shape as two rectangular prisms, a small one on top of a bigger one. Find their volumes individually, and then add them together:

Small rectangular prism

Volume=length*width*depth

=2*3*(7-5)

=6*2

=12cm³

Bigger rectangular prism

Volume=length*width*depth

=6*3*5

=6*15

=90cm³

12+90=102cm³

Answer and Step-by-step explanation:

Half of them should be plain, so 46 plain bagels .

This is because the first set was split evenly, so that must mean this set should be split evenly as well.

Half of 92 is 46.
