Interest centers around the nature of an oven
purchased at a particular department store. It can be
either a gas or an electric oven. Consider the decisions
made by six distinct customers.
(a) Suppose that the probability is 0.40 that at most
two of these individuals purchase an electric oven.
What is the probability that at least three purchase
the electric oven?
(b) Suppose it is known that the probability that all
six purchase the electric oven is 0.007 while 0.104 is
the probability that all six purchase the gas oven.
What is the probability that at least one of each
type is purchased?
Answers
Using the concept of complementary probabilities, it is found that:
a) 0.6 = 60% probability that at least three purchase the electric oven.b) 0.889 = 88.9% probability that one of each type is purchased.-----------------------
Two probabilities are complementary if their sum must be 100% = 1.-----------------------
Item a:
At most 2 and at least 3 are complementary.0.4 probability of at most 2.Thus:
\(p = 1 - 0.4 = 0.6\)
0.6 = 60% probability that at least three purchase the electric oven.
-----------------------
Item b:
0.007 probability of all electric.0.104 probability of all gas.All the same types, and at least one of each are complementary.The probability of all the same type is:
\(p = 0.007 + 0.104 = 0.111\)
Thus, the probability of at least one of each type is:
\(p = 1 - 0.111 = 0.889\)
0.889 = 88.9% probability that one of each type is purchased.

Answers
Answer:
(x - 5)² + (y + 6)² = 16
Step-by-step explanation:
assuming you require the equation of the circle
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
here (h, k ) = (5, - 6 ) and r = 4 , then
(x - 5)² + (y - (- 6) )² = 4² , that is
(x - 5)² + (y + 6)² = 16
It takes Andre 4 minutes to swim 5 laps How many minutes per lap is that?
Answers
Answer:
It takes him 1 minute and 25 seconds
Step-by-step explanation:
5 ÷ 4 = 1.25
The number of laps per minute is 1.25 laps.
Given that, time = 4 minutes and the number of laps = 5.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Here,
Number of laps per minute = Total number of laps/Number of minutes
= 5/4

if kerry is correct what is the greatest amount of fizzy drink she can make?
second part:
kerry has 280 ml of applejuice but only has 160 ml of lemonade.
Does this affect the greatest amount of fizzy drink she can make?
Give a reason for your answer.
Answers
a) She can make 400 milliliters of the fizzy drink.
b) The change does not affect the greatest amount of drink.
If kerry is correct what is the greatest amount of fizzy drink she can make?We know that the fizzy drink is 7 parts apple juice and 3 parts lemonade. And Kerry thinks that she has 280ml of apple juice and 180 ml lemonade.
If we divide the total amount of apple juice in 7 parts, then each part has:
280ml/7 = 40ml
Then we need 3 parts of 40ml of the lemonade, this is:
3*40ml = 120ml
Then the total amounf of drink fizz that she can make is:
280ml + 120ml = 400ml.
b) Now she has 160 ml of lemonade, but she needs 120 ml of it, so this change does not affect the greatest amount of fizzy drink she can make.

The test statistic of zequals2.31is obtained when testing the claim that pgreater than0.9.a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed.b. Find the P-value.c. Using a significance level of alphaequals0.10,should we reject Upper H 0or should we fail to reject Upper H 0?
Answers
Answer:
Step-by-step explanation:
a) From the information given, we can state the hypothesis as follows:
For null hypothesis,
p = 0.9
Or
p ≤ 0.9
For alternative hypothesis,
p > 0.9
Because of the greater than inequality symbol in the alternative hypothesis, it means that it is a right tailed test.
b) Since z = 2.31, we would determine the p value by looking at the probability corresponding to the area above the z score from the normal distribution table. Thus
P value = 1 - 0.9896 = 0.0104
Using a significance level of alpha equals 0.10, since alpha, 0.10 is > p value, 0.0104, then we would reject the null hypothesis.
1) Pendant la période des soldes, tous les manteaux d'un magasin sont soldés à 15%.

Quel est son prix après réduction ?
b. Mélanie veut acheter un manteau dont le prix après réduction est de 55,25€.
Quel était son prix initial ?
2) Manu affirme que sur les étiquettes suivantes, le pourcentage de réduction appliqué au prix
de la montre est supérieur à celui appliqué aux lunettes. A-t-il raison ?
45€→ 35,55€
Réduction
de 20%
Answers
Answer: Zemāk
Step-by-step explanation:
1)
a. Le prix du manteau après la réduction de 15% est:
78€ - (15/100)*78€ = 66,30€
Le prix du manteau après la réduction est de 66,30€.
b. Soit x le prix initial du manteau.
Le prix du manteau après la réduction de 15% est:
x - (15/100)*x = 55,25€
Simplifions cette équation:
0,85x = 55,25€
x = 65€
Le prix initial du manteau était de 65€.
2)
Pour les lunettes, le prix initial est de 45€ et la réduction appliquée est de 20%:
45€ - (20/100)*45€ = 36€
Pour la montre, le prix initial est de 35,55€ et la réduction appliquée est également de 20%:
35,55€ - (20/100)*35,55€ = 28,44€
On constate que le pourcentage de réduction est le même pour les deux articles, donc Manu a tort.
. Bert has a well-shuffled standard deck of 52 cards, from which he draws one card; Ernie has a 12-sided die, which he rolls at the same time Bert draws a card. Compute the probability that:
a. Bert gets a Jack and Ernie rolls a five.
b. Bert gets a heart and Ernie rolls a number less than six.
c. Bert gets a face card (Jack, Queen or King) and Ernie rolls an even number.
d. Bert gets a red card and Ernie rolls a fifteen.
e. Bert gets a card that is not a Jack and Ernie rolls a number that is not twelve.
Answers
Therefore , the solution of the given problem of probability comes out to be a)1/78 ,b)65/624 ,c)1/4 ,d)0 and e)12/13.
What is probability, exactly?The basic goal of any considerations technique is to assess the probability that a statement is accurate or that a specific incident will occur. Chance can be represented by any number range between 0 and 1, where 0 normally indicates a percentage but 1 typically indicates the level of certainty. An illustration of probability displays how probable it is that a specific event will take place.
Here,
a.
P(Bert gets a Jack and Ernie rolls a five) = P(Bert gets a Jack) * P(Ernie rolls a five)
= (4/52) * (1/12)
= 1/78
b.
P(Bert gets a heart and Ernie rolls a number less than six) = P(Bert gets a heart) * P(Ernie rolls a number less than six)
= (13/52) * (5/12)
= 65/624
c.
P(Bert gets a face card and Ernie rolls an even number) = P(Bert gets a face card) * P(Ernie rolls an even number)
= (12/52) * (6/12)
= 1/4
d.
P(Bert gets a red card and Ernie rolls a fifteen) = 0
e.
Ernie rolls a number that is not twelve, and Bert draws a card that is not a Jack:
A regular 52-card deck contains 48 cards that are not Jacks,
so the likelihood that Bert will draw one of those cards is 48/52, or 12/13.
On a 12-sided dice with 11 possible outcomes,
Ernie rolls a non-12th-number (1, 2, 3, etc.).

The graph of the invertible function f is shown on the grid below.
What is the value of f -1(6)?
Answers
We have been given graph of function \(y=f(x)\). We are asked to find the value of \(f^{-1}(6)\) from the graph of \(y=f(x)\).
We know that to find an inverse function is a function that reverses another function. A function f(x) gives an output of y, when we input some value of x. The inverse of f(x) will give the same value of x from value of y.
So to find inverse of a function we need to switch all x and y values.
We can see that \(f(4)=6\), so to to find value of \(f^{-1}(6)\), we have to switch x and y values.
After switching x and y values, we will get:
\(f^{-1}(6)=4\)
Therefore, \(f^{-1}(6)=4\).

a norman window has the shape of a rectangle surmounted by a semicircle. if the perimeter of the window is 30 ft, express the area a of the window as a function of the width x of the window.
Answers
The area a of the window as a function of the width x of the window 12x -(4 + π)x2/8
Let y be the height of the window's rectangular part, and let P represent the window's perimeter.
P then equals x plus 2y plus the length of the semicircular part. The radius of the semicircular part is x/2.
So, P = x + 2y + (1/2)(circumference)
P = x + 2y + (1/2)(2)π(x/2)
P = x + 2y +πx/2 = 24
2y = 24 - x - πx/2
y = 12 - x/2 - πx/4 = 12 - (2 + π)x/4
A = xy + (1/2)π(x/2)2
= x(12 - (2 + π)x/4) + πx2/8
= 12x -(2 + π)x2/4 + πx2/8
= 12x - (4 + 2π)x2/8 + πx2/8
= 12x - 4x2/8 - πx2/8
= 12x -(4 + π)x2/8
