Answer:
51°
Step-by-step explanation:
Note that the square in the angle place = 90°.
Also note, that a complete circle is 360°.
Set the equation. Let the ? be denoted by the variable x:
x + 90+ 124 + 95 = 360
Simplify. Combine like terms:
x + (90 + 124 + 95) = 360
x + (309) = 360
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 309 from both sides of the equation:
x + 309 (-309) = 360 (-309)
x = 360 - 309
x = 51
51° is your answer.

What is probability?
Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.
The sample space is the set of all possible outcomes of an experiment or event.
In this case, the experiment is choosing one card from a set of eight labeled cards.
The sample space for this experiment is the set of all possible cards that can be chosen.
In the given problem, there are eight cards labeled A, D, D, I, T, I, O, N.
The sample space is the set of all possible cards that can be chosen, which is {A, D, D, I, T, I, O, N}.
This is because each card is distinct and can be chosen independently of the others.
Therefore, the correct answer is S = {A, D, D, I, T, I, O, N}.

Find the value of x
Please
Answer:
77.67
Step-by-step explanation:
\((3x + 127) = 360\)
You first write it in this form and solve the equation.
Then you would find x to be
\(x = 77.67\)
Step-by-step explanation:
To solave this, you need to learn/know that :
3x +127 and 23 are supplementary
so
3x+127 + 23 = 180
3x = 30
x = 10 units
Another way :
Angle G = 1/2 * (large intercepted arc - small intercepted arc )
23 = 1/2 ( (360 - (3x+127) ) - (3x-127) )
23 = 1/2 ( 360 -3x - 127 - 3x - 127)
23 = 1/2 ( 106 -6x )
23 = 53 - 3x
x = 10 units
One-third of the students in Mrs. Hayko's class walk to school. Of the students who do not walk to school, four-fifths take the bus.
a.) What fraction of the students in Mrs. Hayko's class take the bus to school?
b.) How many students might be there in her class?
Answer:
The possible number of students in Mrs. Hayko's class is limited to 15 or 30, as higher multiples of 15 would exceed the desired class size.
Step-by-step explanation:
a)
Let 'x' be the total number of students in Mrs. Hayko's class.
One-third of the students walk to school: (1/3)x.
The remaining students who do not walk to school: (2/3)x.
Four-fifths of the non-walking students take the bus: (4/5) * (2/3)x.
Simplify to find the fraction of students taking the bus: (8/15)x.
b)
Consider different values for 'x' to find a whole number of students taking the bus.
Start with a small number, such as x = 15.
Calculate the number of students taking the bus using (8/15)x.
If the result is a whole number, it's a possible class size.
Repeat with different values of 'x' until a whole number is obtained.
The possible number of students in Mrs. Hayko's class could be 15, 30, or any other multiple of 15.

The fraction of crayons that are blue triangle is 1/5.
The ratio of blue rounds to non-blue crayons is
The fraction of footballs that are brown rubber footballs is 8/15 and here are 4 times as many rubber footballs as non-rubber footballs
What is Fraction?A fraction represents a part of a whole.
1. Let's say Alexa had a total of 5x crayons in the bag.
the number of blue crayons in the bag is 2x,
There is one triangle for every two round crayons,
(1/2) × 2x = x (By condition)
So, the fraction of crayons that are blue triangle is x / 5x = 1/5.
The number of blue round crayons is 2x.
The number of non-blue crayons is 5x - 2x = 3x,
The ratio of blue rounds to non-blue crayons is 2x / 3x = 2/3.
2.
4 out of 5 wall footballs are rubber, 4/5 of the footballs in the bag are rubber.
The fraction of rubber footballs that are brown is 2/3.
The fraction of footballs that are brown rubber footballs is (4/5) × (2/3) = 8/15.
The fraction of non-brown rubber footballs is (4/5) - (8/15) = 4/15.
The ratio of rubber footballs to non-rubber footballs is (4/5) / (1/5) = 4.
So there are 4 times as many rubber footballs as non-rubber footballs
Hence, the fraction of crayons that are blue triangle is 1/5.

3. A leaking tap drips water at 0,5 ml/sec. Convert this rate to l/h.
Answer: 1.8 L/h
Step-by-step explanation:
To convert the rate of water dripping from a tap from millilitres per second (ml/sec) to litres per hour (L/h), we need to use conversion factors.
Step 1:
First, let's convert the rate from millilitres per second to litres per second.
There are 1000 millilitres in a litre, so we can divide the rate in millilitres per second by 1000 to get the rate in litres per second:
\(\LARGE \boxed{\textsf{0.5 ml/sec $\div$ 1000 = 0.0005 L/sec}}\)
Step 2:
We can convert the rate from litres per second to litres per hour. There are 3600 seconds in an hour, so we can multiply the rate in litres per second by 3600 to get the rate in litres per hour:
\(\LARGE \boxed{\textsf{0.0005 L/sec $\times$ 3600 = 1.8 L/h}}\)
Therefore, the rate of water dripping from the tap is 1.8 L/h.

elijah bought a total of 16 pounds of peanuts and cashews and pain $49.50. If peanuts cost $2.75 per pound and cashews nuts cost $3.25 per pound, how many pounds of cashew nuts did he buy?
Answer:
The answer to your question is He bought 11 pounds of cashew.
Step-by-step explanation:
Data
Total pounds = 16
peanuts = p = $2.75
cashew = c = $3.25
total cost = $49.5
Process
1.- Write two equations to solve this problem
p + c = 16 Equation 1
2.75p + 3.25c = 49.50 Equation 2
Solve the system by substitution
2.- Solve equation 1 for p
p = 16 - c
Substitute p in equation 2
2.75(16 - c) + 3.25c = 49.5
Expand
44 - 2.75c + 3.25c = 49.5
Solve for c
3.25c - 2.75c = 49.5 - 44
0.5c = 5.5
c = 5.5/0.5
c = 11
3.- Find p
p = 16 - 11
p = 5 pounds
4.- Conclusion
Ellijah bought 11 pounds of cashew and 5 pounds of peanuts

The measure of the segment xy of the given right angle triangle is; 36 units
How to use trigonometric ratios?This question can be best understood if the trigonometric ratios are briefly highlighted since it has been used in the question. Cos f is given as 4/9. We know that the cos of an angle is derived as the adjacent divided by the hypotenuse. In other words, the cosine of angle f is given as;
Cos f = Adjacent / Hypotenuse
Thus;
Cos f = 4/9
From the triangle shown in the attachment, the adjacent is XW while the hypotenuse is XY. Hence, the adjacent is 16 units and the hypotenuse is unknown. Since the measurements given in the question are a ratio of the original dimensions, the relationship can be expressed as follows;
4/9 = 16/XY
Where XY is the unknown side
By cross multiplication, you now arrive at,
4XY = 9 * 16
XY = 144/4
XY = 36
Therefore, XY measures 36 units

The predicted sales for the current month (February 2003) is approximately 44.3. Thus, the correct option is (c) 44.3.
What is probability?Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.
To determine the predicted sales for the current month (February 2003) using the given linear regression model, we need to substitute the values of the intercept and slope coefficients into the equation:
Predicted Sales = Intercept + Slope * Month
Using the provided coefficients:
Intercept = 4.3
Slope = 1.6
Let's calculate the predicted sales for February 2003:
Predicted Sales = 4.3 + 1.6 * (24 + 1)
Predicted Sales = 4.3 + 1.6 * 25
Predicted Sales = 4.3 + 40
Predicted Sales = 44.3
Therefore, the predicted sales for the current month (February 2003) is approximately 44.3. Thus, the correct option is (c) 44.3.

Answer:
15 miles/hour = 0.25 miles/minute
The cyclist would have traveled 5 miles in 20 minutes.
Step-by-step explanation:
15 miles per hour is written as
15 miles/hour
To convert 15 miles/hour to miles/minute
From 1 hour = 60 minutes
∴ 15 miles/hour = 15 miles/ 60 minutes
= (15/60) miles/minute
= 0.25 miles/minute
To calculate how many miles the cyclist will travel in 20 minutes
That is, Time, t = 20 minutes
Velocity, v = 15 miles/hour = 0.25 miles/minute
Distance, s = ??
From,
\(Velocity = \frac{Distance}{Time}\\\)
∴\(Distance = Velocity\) × \(Time\)
\(Distance = 0.25 miles/minute\) × \(20 minutes\)
\(Distance = 5 miles\)
Hence, The cyclist would have traveled 5 miles in 20 minutes.

a medical researcher wants to investigate the amount of time it takes for patients' headache pain to be relieved after taking a new prescription painkiller. she plans to use statistical methods to estimate the mean of the population of relief times. she believes that the population is normally distributed with a standard deviation of 22 minutes. how large a sample should she take to estimate the mean time to within 2 minutes with 95% confidence?
To estimate within 2 minutes of the mean for the 95% of confidence, the sample size should be 465.
Since the formula we refer to for calculating the margin error is
E= Z*(standard deviation /set(sample size )), where Z is the z score.
So, for estimating sample size, the deviated formula will be :
sample size= (Z*standard deviation/margin error )^2
Since we are provided with a standard deviation which is 22 and a confidence interval of 95% and a mean time which is 2 and a confidence of 95% the z score is 1.96. So, the sample size is:

consider an undirected graph that has 100 vertices. for any pair of vertices, only 1 edge can connect them. in other words, you cannot have 2 edges connecting vertex a directly to vertex b. also assume that there are no self-loops, i.e. an edge that goes from vertex a to vertex a. what is the maximum number of edges that can be in this specific graph?
So the maximum number of edges in an undirected graph with 100 vertices is 4950.
In an undirected graph, each edge connects two vertices, and as such, it is counted twice, once for each vertex it connects. Therefore, the total number of edges in the graph is the sum of the degrees of all vertices, divided by 2.
In a complete graph with n vertices, every vertex is connected to every other vertex, except itself, and so the degree of each vertex is n-1 (it is connected to n-1 other vertices). Therefore, the total number of edges in the graph is:
n * (n-1) / 2
Substituting n = 100, we get:
