Answer:
[tex]P(x=3) = 0.1318[/tex]
Step-by-step explanation:
The question illustrates a binomial distribution and the given parameters are:
Given
[tex]n = 6[/tex] -- sample size
[tex]p = 0.75[/tex] --- probability of success
[tex]r = 3[/tex] --- half of the participant
Using the binomial probability formula, we have:
[tex]P_x = ^nC_xp^x(1-p)^{n-x}[/tex]
For x = 3, the probability is:
[tex]P(x=3) = ^6C_3*0.75^3 * (1-0.75)^{6-3}[/tex]
[tex]P(x=3) = 20*0.75^3 * 0.25^3[/tex]
[tex]P(x=3) = 0.1318[/tex]
Nathan buys 8 bottles of iced tea at the grocery store. He has coupons for $0.35 off the regular price of each bottle. After using the coupons, the total cost of the drinks is $7.20.
Which equation can be used to find the regular price, p, of each bottle of iced tea?
Answer:
$1.25
Step-by-step explanation:
0.35 x 8 = 2.80
7.20 + 2.80 = 10
10 divided by 8 = 1.25
Thank you :)
The equation that can be used to determine the regular price of iced tea is p = 1/8($7.20 - $2.80).
Description of couponsCoupons reduce the price of an item. An item becomes cheaper when coupons are used. Thus, Nathan would buy the iced teas at a cheaper price as a result of the coupons.
Equation that represents the regular price of the iced tea.Discounted price = regular price - discount
$7.20 = p - ($0.35 x8)
$7.20 = p - $2.80
p = $7.20 - $2.80
Price of each bottle = p = 1/8( $7.20 - $2.80)

What is ratio?The numerical relationship between two values that demonstrates how frequently one value contains or is contained within another.
Given:
Keesha keeps track of the fiber she eats to make sure she gets enough each day.
Her breakfast contains 8 grams of fiber, and her recommended daily amount is 25 grams per day.
Keesha wants to know what percent of her daily amount of fiber she has at breakfast.
The table to show an equivalent ratio where the total amount is 100 grams.
Let n be the required value.
That means,
8/25 = n/100
n = 800/25
n = 32
Therefore, her daily amount of fiber is 32%.

To find the value of c, substitute the x and y values of the given point into x and y of the equation, then isolate c. Since that given point is (2,5), substitute 2 for x and 5 for y:
[tex](5) = -2(2)^2+8(2)-c\\5 = -2(4)+16-c\\5 = -8 + 16 - c \\5 = 8 -c\\-3 = -c\\c = 3[/tex]
Thus, c = 3.

The graph of g(x), shown below, resembles the graph of f(x) = x - x2, but it
has been changed somewhat. Which of the following could be the equation
of g(x)?
Anxx
O A. f(x) = (x + 2)4 - (x + 2)2
B. f(x) = x - x2-2
C. f(x) = (x - 2)4 - (x - 2)2
O D. f(x) = x - x2 + 2
Answer:We are given function f(x) = x^4 - x^2.
We need to find the equation of function g(x) according to shown graph.
We can apply rules of transformation to get the function g(x) by using given graph.
Function g(x) graph is being shift a half or 0.5 units up of the graph f(x).
When graph shift k units up, we add k to given function.
Where k is some constant.
In the graph f(x) is being shifted 0.5 units up.
So, we would add 0.5 in f(x) = x^4 - x^2 function.
On adding 0.5 we get
g(x) = f(x)+0.5 = = x^4 - x^2 +0.5.
Therefore, correct option is second option.
g(x) = x^4 - x^2 +0.5.

An automotive manufacturer wants to know the proportion of new car buyers who prefer foreign cars over domestic. Step 2 of 2 : Suppose a sample of 768 new car buyers is drawn. Of those sampled, 192 preferred foreign over domestic cars. Using the data, construct the 80% confidence interval for the population proportion of new car buyers who prefer foreign cars over domestic cars. Round your answers to three decimal places.
Answer:
The 80% confidence interval for the population proportion of new car buyers who prefer foreign cars over domestic cars is (0.23, 0.27).
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].
Suppose a sample of 768 new car buyers is drawn. Of those sampled, 192 preferred foreign over domestic cars.
This means that [tex]n = 768, \pi = \frac{192}{768} = 0.25[/tex]
80% confidence level
So [tex]\alpha = 0.2[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.2}{2} = 0.95[/tex], so [tex]Z = 1.28[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.25 - 1.28\sqrt{\frac{0.25*0.75}{768}} = 0.23[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.25 + 1.28\sqrt{\frac{0.25*0.75}{768}} = 0.27[/tex]
The 80% confidence interval for the population proportion of new car buyers who prefer foreign cars over domestic cars is (0.23, 0.27).
