the profit when selling 'x' pairs of shoes is P(x)=-4x^2+32x-39. How many pairs of shoes should be sold in order to maximize the profit
4 pairs
5 pairs
6 pairs
7 pairs
Answer:
A
Step-by-step explanation:
The profit for selling x pairs of shoes is given by:
[tex]P(x)=-4x^2+32x-39[/tex]
And we want to determine the number of pairs that needs to be sold in order to maximize profit.
Since the function is a quadratic with a negative leading coefficient, the maximum profit will occur at its vertex point. The x-coordinate of the vertex of a quadratic is given by:
[tex]\displaystyle x=-\frac{b}{2a}[/tex]
In this case, a = -4, b = 32, and c = -39. Substitute and evaluate:
[tex]\displaystyle x=-\frac{(32)}{2(-4)}=\frac{32}{8}=4[/tex]
So, in order to maximize profit, only four pairs of sohoes should be sold.
Our answer is A.
Answer:
A

f(x) = x3 + 6x2 – x
f(x) = 30?
Answer and Step-by-step explanation:
The answer is 2 (which is equal to x).
If you were to plug 2 in to the function, the result if 30.
[tex]x^{3}+ 6x^{2} -x\\\\\\\\(2)^3+6(2)^2 - 2 = 30 = f(2)[/tex]

You put $425 Into a savings account that earned 8% annual interest compounded quarterly a) Write a function that represents the balance of the account after t years. b) How much money will you have in the account after 6 years? (Be sure to round appropriately, this is money!)
9514 1404 393
Answer:
a) f(t) = 425(1.02)^(4t)
b) $683.59
Step-by-step explanation:
a) The compound interest formula is ...
A = P(1 +r/n)^(nt)
giving the balance A of an investment of principal P for t years at annual rate r compounded n times per year.
We have P = 425, r=0.08, and n=4, so we can write the function f(t) as ...
f(t) = 425(1+0.08/4)^(4t)
f(t) = 425(1.02)^(4t)
__
b) The balance after 6 years is ...
f(6) = 425(1.02^(4·6)) = 425(1.02^24) = 683.59
The account balance after 6 year will be $683.59.

Find the slope of the line
A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 431 gram setting. It is believed that the machine is underfilling the bags. A 26 bag sample had a mean of 421 grams with a standard deviation of 20. A level of significance of 0.01 will be used. Assume the population distribution is approximately normal. Is there sufficient evidence to support the claim that the bags are underfilled
Answer:
The p-value of the test is of 0.0086 < 0.01, which means that there is sufficient evidence to support the claim that the bags are underfilled
Step-by-step explanation:
A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 431 gram setting. It is believed that the machine is underfilling the bags.
At the null hypothesis, we test if they are at the correct weight, that is:
[tex]H_0: \mu = 431[/tex]
At the alternative hypothesis, we test if they are underfilled, that is:
[tex]H_1: \mu < 431[/tex]
The test statistic is:
We have the standard deviation for the sample, so the t-distribution is used to solve this question
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.
431 is tested at the null hypothesis:
This means that [tex]\mu = 431[/tex]
A 26 bag sample had a mean of 421 grams with a standard deviation of 20.
This means that [tex]n = 26, X = 421, s = 20[/tex]
Value of the test statistic:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{421 - 431}{\frac{20}{\sqrt{26}}}[/tex]
[tex]t = -2.55[/tex]
P-value of the test and decision:
Using a t-distirbution calculator, the p-value is found using a left-tailed test(test if the mean is less than a value), with 26 - 1 = 25 df and t = -2.55. This p-value is of 0.0086.
The p-value of the test is of 0.0086 < 0.01, which means that there is sufficient evidence to support the claim that the bags are underfilled

Answer:
w = 5
Step-by-step explanation:
The perimeter of a rectangle is given by
P = 2(l+w)
28 = 2(2w-1 + w)
Combine like terms
28 =2(3w-1)
Divide each side by 2
28/2 = 2/2(3w-1)
14 = 3w-1
Add 1 to each side
14+1 = 3w-1+1
15 = 3w
Divide each side by 3
15/3 =3w/3
5 =w

Answer:
P = 1 / 40320 or P = 2.48*10⁻⁵
Step-by-step explanation:
The total number of outcomes To is:
To = 8! To = 8*7*6*5*4*3*2
To = 40320
Of all these outcomes there is only one proper outcome, therefore the probability of having all men and women in alphabetical order is:
P = 1 / 40320 or P = 2.48*10⁻⁵

8. The distance formula is d=rt,
where d is distance, ris rate, and t
is time. Find the time it takes to
drive 252 miles going 45 miles per
hour.
Answer:
t=5.6
Step-by-step explanation:
The given equation is d=rt.
WE are also given other information such as the distance (d) and the rate (r)
d=252 and r=45
So, we can plug this into the equation:
252=45t
Now, we divide 45 from both sides to find t.
252/45=t
t=5.6
