In the Kite Club, there are a total of 23 kids. There are 7 more girls than boys. Write two equations below to represent the situation. Then, graph to find the number of boys and girls in the club.
Answer:
15 girls
Step-by-step explanation:
The two equations represent the situation will be x + y = 23 and x = y + 7. Then the number of girls is 15 and the number of the boys is 8.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
In the Kite Club, there are a total of 23 kids.
Let x be the number of girls and y be the number of boys.
Then the sum of the girls and boys is 23. Then the equation will be
x + y = 23 …1
There are 7 more girls than boys. Then the equation will be
x = y + 7 …2
From equation 1 and 2, we have
y + 7 + y = 23
2y = 23 - 7
2y = 16
y = 8
Then substitute the value of y in equation 2, then the equation will be
x = 8 + 7
x = 15
Then the number of girls is 15 and the number of the boys is 8.
The graph of the equation is attached below.

The odds in favor of an event are 2:9 or 2/9. What are the odds against the event?
Answer:
Odds against the events are 7/9.
Step-by-step explanation:
It is given that:
Odds in favor of event = 2 : 9 or 2/9
Let,
These odds are out of 1.
The odds against the event would be
Odds against = 1 - 2/9
Odds against = [tex]\frac{9-2}{9}[/tex]
Odds against = [tex]\frac{7}{9}[/tex]
Therefore,
Odds against the events are 7/9.

i. 10g3 27 ^3
Answer:
9
Step-by-step explanation:
Log₃27³
Recall that 27 = 3³
Hence
Log₃27³ = Log₃3³⁽³⁾ = Log₃3⁹
From the laws of logarithms, we know that
Logₐa = 1 and Log aˣ = xLog a
As such, applying both laws
Log₃3⁹ = 9Log₃3
since Log₃3 = 1
9Log₃3 = 9 * 1
= 9

given two angles that measure 50 degrees and 90 degrees and a side that measures 4 feet
What is the question? Please specific!
Answer:The angles are the only constraint here that counts. If one of the three interior angles of a supposed triangle is 50 degrees and another is 80 degrees, then the third angle must be 50 degrees. Thus, we have a 50-50-80 triangle, which is isosceles though not a right triangle. If 4 feet is a measure of one of the equal sides of a supposed triangle, then obviously the adjacent side also has measure 4 ft.
The set of angles remains the same (50-50-80), but subject to the constraint mentioned above, the measure of any one of the sides has infinitely many possible values, so long as those values are positive.

Which rate of change (m), would represent this proportional relationship?
Answer:
The rate of change (m) = 1.1
Option B is correct option.
Step-by-step explanation:
Which rate of change (m), would represent this proportional relationship?
Rate of change can be found using slope formula:
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
You can choose any two values of x and y from the table. I am choosing 1st and 2nd values
From the table we get: [tex]x_1=2, y_1=2.2, x_2=4, y_2=4.4[/tex]
Putting values in the formula and finding slope (rate of change)
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{4.4-2.2}{4-2}\\Slope=\frac{2.2}{2}\\Slope=1.1[/tex]
So, slope m = 1.1
The rate of change (m) = 1.1
Option B is correct option.

Is standard deviation a measure of center or a measure of
variation ?
A. measure of center
B. measure of variation
Answer:
The answer is "B" which is the measure of variation
Hope this helps
Step-by-step explanation:
Standard deviation is a measure of variation.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The standard deviation is a measure of the amount of variation or dispersion of a set of values.
A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.
Measures of variation in statistics are ways to describe the distribution or dispersion of data.
Hence, standard deviation a measure of variation.

Step-by-step explanation:
We can use any two points to give the answer, by doing the slope of the graph, using the formula:
slope = (y2-y1)/(x2-x1)
Using the points (0, 0) and for example (16, 4)
we have:
slope = (4-0)/(16-0) = 4/16 = 1/4 = $0.25 per pound
