From the candy factory, Stattles candies come in five different colors that are equally distributed (20% orange), and each 14 ounce bag has a random sample of 220 of Stattles.
a. Find the mean and standard deviation of the sampling distribution of p
b. Calculate the probability that Cindy will get at least 48 orange Stattles in her next 14 ounce bag.
a. The mean of the sampling distribution is 0.2 and the standard deviation is 0.027. b. The probability that Cindy will get at least 48 orange Stattle is approximately 0.0901.
What is the binomial distribution's normal approximation?A method for estimating the probability of a binomial distribution using a normal distribution is known as the normal approximation to the binomial distribution. When the sample size is sizable and the success probability is not too close to 0 or 1, it can be employed. To utilise this approximation, we must first get the binomial distribution's mean and standard deviation, then normalise the distribution using the z-score calculation.
As 20% of the candies are orange, the mean of the sampling distribution of p is equal to the population percentage, which is 0.2.
The standard deviation of the sampling distribution of p can be found using the formula:
σp = sqrt((p * (1 - p)) / n)
Substituting the values:
σp = sqrt((0.2 * 0.8) / 220) = 0.027
So the mean of the sampling distribution is 0.2 and the standard deviation is 0.027.
b. Let X be the number of orange Stattles in the bag.
The z-score is given as:
z = (X - μ) / σ
z = (48 - 44) / 2.974 = 1.34
So the probability that Cindy will get at least 48 orange Stattles in her next 14 ounce bag is approximately 0.0901.

Solve for x.
Answer and Step-by-step explanation:
To solve for x, we need to look at 2 deciding factors that allows us to be able to find x.
We are given 2 parallel lines, denoted by the arrow pointing right on the end of both of them, and a transversal line that cuts through the two lines. Because the lines are parallel, the angles that are formed by the transversal like will be equal or correspondent to each other in a few ways.
For the angles we are given, the angles are on the same side of the transversal line, and on the top of their respective parallel lines. Because of this, the angles are equal to each other.
To solve, set the two angles equal to each other.
4x + 20 = 2x + 60
Subtract the 2x from both sides of the equation.
2x + 20 = 60
Subtract the 20 from both sides of the equation.
2x = 40
Divide both sides by 2.
x = 20
x is equal to 20.

to find the value for x.
Concept applied -
Here in the figure, these two angles let's say 1 = 4x + 20° and 2 = 2x + 60° are corresponding angles. And we know that corresponding angles are equal. As all these angles that have the same position in leu the parallel lines and the transversal are corresponding pairs. Therefore, 1 = 2
Solution -
➙ 4x + 20° = 2x + 60°
➙ 4x - 2x = 60° - 20°
➙ 2x = 40°
➙ x = 40°/2

Line G passes through the point (7,11) and is parallel to the line given by y = 4(3x + 2). What is the equation of line G? Give your answer in the form y = mx + c, where m and c are integers or fractions in their simplest forms.
Answer:
y = 12x - 73
Step-by-step explanation:
Pre-SolvingWe are given the line y=4(3x+2).
We want to find the equation of line G, which contains the point (7,11), and is parallel to y=4(3x+2) in the form y=mx+c. m is the slope, and c is the value of y at the y-intercept.
Parallel lines have the same slopes. So, we should start by finding the slope of y=4(3x+2).
SolvingWe can do the distributive property to distribute the 4 to both terms on the right side.
y=4(3x+2) => y=12x + 8
Notice how this equation is written in the form y=mx+c. As 12 is written in the place where m is, the slope of this line is 12.
It is also the slope of line G.
We can replace m in y=mx+c with 12 for line G. We'll get:
y=12x + c
Now, we need to find c.
We can use the point (7,11) to help us find c.
Substitute 7 for x and 11 for y.
11 = 12(7) + c
Multiply.
11 = 84 + c
Subtract 84 from both sides
-73 = c
Substitute -73 as c.
y = 12x - 73
fourth degree and a single zero of -3
The degree of a polynomial is the highest power of the polynomial.
The polynomial is \(\mathbf{P(x) = (x + 3)^4}\)
The degree is given as:
\(\mathbf{n = 4}\)
The zero is given as:
\(\mathbf{x = -3}\)
Add 3 to both sides
\(\mathbf{x + 3= 0}\)
From the question, we understand that the polynomial has a single zero.
So, the polynomial is:
\(\mathbf{P(x) = (x + 3)^n}\)
Substitute 4 for n
\(\mathbf{P(x) = (x + 3)^4}\)
Hence, the polynomial is \(\mathbf{P(x) = (x + 3)^4}\)

a player scored 89 points in a single professional basketball game. he made a total of 55 baskets, consisting of field goals (worth two points) and fouls shots (worth one point). find the number of field goals and the number of fouls shots that the player made
The player made 38 foul shots.
Let's indicate the player's total number of field goals made by F and foul shots attempted by S. Based on the data in the problem, we may construct an equation system:
F + S = 55 (the player made a total of 55 baskets) (the player made a total of 55 baskets)
2F + S = 89 (the player scored a total of 89 points) (the player scored a total of 89 points)
The substitution approach can be used to find the values of F and S. We start by resolving the initial S equation:
S = 55 - F
Next, we change S in the second equation to the following expression:
2F + (55 - F) = 89
When we simplify and find F, we obtain:
F = 17
Hence, the player connected on 17 field goals. We may change this value of F into the first equation and then solve for S to determine the total number of foul shots:
17 + S = 55
S = 38
The player so scored 38 fouls.

Which of the following is true of the location of the terminal side of an angle 0 who's sine value is 1/2?- has a reference angle of 30° and is in quadrant one or two- as a reference angle 30° and is in quadrant one or four- has a reference angle of 60° and is in quadrant one or two- as a reference angle of 60° in is in quadrant one or four
Out of the following the statement has a reference angle of 30° and is in quadrant one or two- is true of the location of the terminal side of an angle 0 whose sine value is 1/2.
Since the reason behind this is that the sine value of 1/2 can be written as sin(30°), this means that the terminal side of the angle is located at 30°, which is either quadrant one or two. Quadrant one is the upper right quadrant of the coordinate plane, and quadrant two is the upper left quadrant.
The reference angle of an angle is the angle between the terminal side of the angle and the positive x-axis. In this case, the reference angle would be 30°. The reference angle of an angle is important because it is used to determine the quadrant in which the terminal side of the angle is used to determine the quadrant in which the terminal side of the angle is located. The reference angle must be less than 90° in order for the terminal side to be located in the first and second quadrants.

If P(A | B) = P(A) and P(B | A) = P(B), then the events are independent. D. If P(A | B) = P(A) and P(B | A) = P(B), then the events are dependent.
Using conditional probability, it is found that the correct statement is given by:
C. If P(A | B) = P(A) and P(B | A) = P(B), then the events are independent.
What is Conditional Probability?Conditional probability is the probability of one event happening, considering a previous event. The formula is:
\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)
In which:
P(B|A) is the probability of event B happening, given that A happened.\(P(A \cap B)\) is the probability of both A and B happening.P(A) is the probability of A happening.If two events are independent, we have that:

Using common factor method, sum of the given expressions is 17.14m + 9.37
what is common factor ?
In mathematics, a common factor is a factor that two or more numbers have in common. For example, the numbers 12 and 18 have common factors of 1, 2, 3, and 6. The greatest common factor (GCF) is the largest number that divides evenly into two or more numbers.
In algebra, we often use the term "common factor" when referring to expressions. When two or more algebraic expressions have a factor in common, we can use the distributive property to factor out the common factor.
According to the question:
To add the expressions (5.19+4m)+(4.18+3.95m), we can first group the like terms:
(5.19 + 4.18) + (4m + 3.95m)
9.37 + 7.95m
So, the sum of the expressions is:
(5.19+4m)+(4.18+3.95m) = 9.37 + 7.95m
Now, we can use the distributive property to factor out a common factor of m from 7.95m:
9.37 + 7.95m = 4m + (5.19 + 7.95)m
We can factor out a common factor of 1 from (5.19 + 7.95)m:
4m + (5.19 + 7.95)m = (4 + 5.19 + 7.95)m
Adding the coefficients, we get:
4 + 5.19 + 7.95 = 17.14
Therefore, the sum of the expressions is:
(5.19+4m)+(4.18+3.95m) = (4m+5.19)+(3.95m+4.18)= 17.14m + 9.37.
