Answer: 37
Step-by-step explanation:
let x be the number of students who pass "fante". Then the number of students who passed "Ga" will be x + 6.
with the added information that 8 students passed both we can say:
(x + x + 6) - 8 = 60
2x + 6 = 68
2x = 62
x = 31
.: x + 6 = "only Ga pass" = 37
The question does not make it clear if it is asking for students who *only* passed Ga, or students who passed Ga + those who passed both. I'll assume the former though. Otherwise the answer would be 37 + 8 = 45 students

In a simple linear regression model we use the normal quantile plot of the residuals to evaluate if it is reasonable to assume the errors come from a normal distribution.
The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution centred on the mean, implying that data closer to the mean occur more frequently than data further away from the mean.
The normal quantile plot of the residuals in a simple linear regression model is used to establish if it is reasonable to think the errors are normal.

. if it is assumed that all poker hands are equally likely, what is the probability of being dealt a. a flush? (a hand is said to be a flush if all 5 cards are of the same suit.) b. one pair? (this occurs when the cards have denominations where and are all distinct.)
a) The probability of being dealt a flush is approximately 0.00198, or about 0.2%.
b) The probability of being dealt one pair is approximately 0.422, or about 42.2%.
a. To find the probability of being dealt a flush, we need to first determine how many possible flush hands there are, and then divide that by the total number of possible hands. There are 4 suits in a deck of cards, so there are 4 ways to choose which suit the flush will be in.
Once we have chosen a suit, there are 13 cards of that suit, and we need to choose 5 of them. The number of ways to choose 5 cards from 13 is given by the combination formula: C(13,5) = 1287. Therefore, there are 4 x 1287 = 5148 possible flush hands.
The total number of possible hands is given by the combination formula for choosing 5 cards from a deck of 52: C(52,5) = 2598960. Therefore, the probability of being dealt a flush is 5148/2598960, which simplifies to approximately 0.00198, or about 0.2%.
b. To find the probability of being dealt one pair, we need to first determine how many possible one pair hands there are, and then divide that by the total number of possible hands. There are 13 denominations in a deck of cards, so there are 13 ways to choose which denomination will form the pair.
Once we have chosen a denomination, there are 4 cards of that denomination, and we need to choose 2 of them. The remaining 3 cards must each be a different denomination from the pair, so there are 12 denominations left to choose from, and 4 cards of each denomination.
We need to choose 3 of these 12 denominations, and then 1 card from each of those 3 denominations. The number of ways to choose 2 cards from 4 is given by the combination formula: C(4,2) = 6. The number of ways to choose 3 denominations from 12 is given by the combination formula: C(12,3) = 220.
The number of ways to choose 1 card from each of 3 denominations is 4 x 4 x 4 = 64. Therefore, the total number of possible one pair hands is 13 x 6 x 220 x 64 = 1,098,240. Dividing this by the total number of possible hands gives us the probability of being dealt one pair, which is 1,098,240/2598960, or approximately 0.422, or about 42.2%.

C. a third bond is worth $100 and grows in value by 4 percent each year, but the interest is applied continuously, at every moment. The value of this bond after years is given by 100-Order the bonds from slowest growing to fastest growing. Explain how you know
We can order the bonds from slowest-growing to fastest-growing as:
First bond: fixed growth rate of $50 per year
Third bond: growth rate of 4% per year, compounded continuously
Second bond: growth rate of 6% per year, compounded annually
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To order the bonds from slowest growing to fastest growing, we need to compare their growth rates.
The first bond grows at a fixed rate of $50 per year, regardless of how long it is held.
So its growth rate is constant and does not change with time.
The second bond is worth $500 and grows at a fixed annual rate of 6%, so its value after one year will be:
Value after one year
= $500 + 0.06 x $500
= $530
After two years, its value will be:
Value after two years.
= $530 + 0.06 x $530
= $561.80
We can see that the second bond's growth rate is increasing over time since the increase in value each year is calculated as a percentage of the new value.
The third bond is worth $100 and grows at an annual rate of 4% that is applied continuously.
The formula for the value of a continuously compounded bond after t years = $100 x e^(0.04t)
where e is the mathematical constant approximately equal to 2.718.
After one year,
The value of the third bond.
= $100 x e^(0.04 x 1) = $104.08
After two years,
Value after two years
= $100 x e^(0.04 x 2)
= $108.24
We can see that the growth rate of the third bond is also increasing over time because the interest is being compounded continuously.
Now,
We can order the bonds from slowest-growing to fastest-growing as:
First bond: fixed growth rate of $50 per year
Third bond: growth rate of 4% per year, compounded continuously
Second bond: growth rate of 6% per year, compounded annually

There are [tex]10^{4}[/tex] = 10,000 different possible musical entertainment lineups that can be created from a list of 10 songs.
This is computed by using the formula for combinations without repetition, which is [tex]n^{r}[/tex], where n is the number of items in the list and r is the number of items to be selected. In this case, n = 10 and r = 4, which results in [tex]10^{4}[/tex] = 10,000.
It is important to note that this calculation does not take into account any repetitions of songs, so if the same song appears more than once in the list, then the actual number of possibilities could be less.

a) The histogram for the data is illustrated below.
b) The cumulative percentage polygon is define in the histogram
c) The amount does the monthly electricity cost seem to be concentrated is 128 - 152
A histogram is a graphical representation of a frequency distribution. It consists of a set of bars that represent the frequency of data within certain intervals, also known as bins. The height of each bar represents the frequency or count of data points that fall within that bin.
To create a histogram for the electricity cost data, we need to first decide on the number and size of the bins. One common rule is to choose the number of bins as the square root of the sample size. In this case, we have 50 data points, so we can choose about 7 bins. The size of the bins can be determined by dividing the range of the data by the number of bins.
Once we have determined the number and size of the bins, we can create the histogram by drawing a set of bars with heights proportional to the number of data points that fall within each bin. The histogram can be further enhanced by adding labels for the x and y-axes, a title, and a legend.

find an obtuse angle, θ, such that 0 ≤ θ ≤ 2π and has the same sine as -275° (please explain)
The obtuse angle such that has the same sine as -275° is θ = 95°
How to find the angle θ?We want to find an obtuse angle (with a measure larger than 90°) in the range 0 ≤ θ ≤ 2π (or 0 < θ < 360°, after that we can change the units from degrees to radians) such that sin(θ) = sin(-275°)
First, remember that the sine function has a periodicity of 360°, then:
sin(-275°) = sin(-275° + 360°) = sin(85°)
Now we know that the sine function is symmetric around x = 90°
Then:
sin(90° + x) = sin(90° - x)
if we take x = 5° we will get:
sin(90° + 5°) = sin(90° - 5°)
sin(95°) = sin(85°) = sin(-275°)
Thus we can conclude that θ = 95°
That is the obtuse angle.

Basic
Answer:
Period is [tex]\mbox{\huge {\boxed{\pi }}}[/tex]
Step-by-step explanation:
Each gridline marker on the horizontal axis is π/4
The period of this function is the horizontal displacement at which the function starts to repeat itself
Looking at the function we see that the minimum value of the function is 1 and occurs first at -π/4 and then at 3π/4
So the period is 3π/4 - (-π/4) = 3π/4 + π/4 = (3/4 + 1/4)π = π
We could also double check this using another point of reference
let's take the peaks of the function
The first peak visible is at -3π/4 and the next peak at π/4
So the period = π/4 - (-3π/4) = π/4 + 3π/4 = π

The bakers in the shop fill 60 boxes.
40% of the boxes are medium, 35% of the boxes are small and the
rest are large.
How many cupcakes have been packed?
The total number of cupcakes packed is 846 cupcakes.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Let's first find out the number of boxes of each size:
40% of 60 boxes = 24 boxes are medium
35% of 60 boxes = 21 boxes are small
The remaining 60 - 24 - 21 = 15 boxes are large
Now we can calculate the total number of cupcakes packed:
24 boxes x 15 cupcakes per medium box = 360 cupcakes in medium boxes
21 boxes x 6 cupcakes per small box = 126 cupcakes in small boxes
15 boxes x 24 cupcakes per large box = 360 cupcakes in large boxes

The point A(2, 1) is a vertex of a square ABCD. M(5, 1) is the point of intersection of the
diagonals of the square. Find the coordinates of B, C and D. (Remember: The diagonals
of a square are equal in length and bisect each other at right angles.)
pls give serious answers!!
Answer:
Step-by-step explanation:
Since M is the point of intersection of the diagonals of the square, it is also the midpoint of both diagonals. This means that AM is equal to half the length of a side of the square and also bisects the angle formed by the two sides that it connects.
Let's call the length of a side of the square s. Then, the distance AM can be found using the Pythagorean theorem:
AM = sqrt((5 - 2)^2 + (1 - 1)^2) = sqrt(3^2 + 0^2) = sqrt(9) = 3
So, the length of a side of the square is 2 * AM = 2 * 3 = 6.
Next, we can use the length of a side and the coordinates of A to find the coordinates of B. Since AB is a side of the square and is 6 units long, we can find B by moving 6 units to the right of A:
B = (2 + 6, 1) = (8, 1)
We can also find the coordinates of C by moving 6 units up and 6 units to the left of A:
C = (2 - 6, 1 + 6) = (-4, 7)
Finally, we can find the coordinates of D by moving 6 units down and 6 units to the right of A:
D = (2 + 6, 1 - 6) = (8, -5)
So, the coordinates of the other vertices of the square are B = (8, 1), C = (-4, 7), and D = (8, -5).

in a certain culture of bacteria, the number of bacteria is increased sixfold in 10 hours. how long did it take for the population to double? [use the natural growth equation.]
To double, the population must increase by a factor of 2, which would take ln(2) / ln(6) = ln(2) / ln(6) * 10 hours = 2.817 hours.
To solve for the time it took for the bacterial population to double, we need to use the exponential growth formula:
[tex]N(t) = N_0 * e^{(kt)[/tex]
where N0 is the initial population, N(t) is the population at time t, k is the growth rate, and e is the base of the natural logarithm (approximately 2.71828).
Since the population is increased sixfold in 10 hours, we can set up the equation as:
[tex]N_0 * e^{(kt)} = 6 * N_0[/tex]
Taking the natural logarithm of both sides gives:
kt = ln(6).
Dividing both sides by k and using the fact that the natural logarithm of 2 is approximately 0.693,
ln(2) / ln(6) = ln(2) / ln(6) * 10 hours = 2.817 hours.
So it took approximately 2.817 hours for the population to double.
