Answer:
GFD = 132.7
Step-by-step explanation:
JIF and GFD are same side interior angles and when the lines are parallel, same side interior angles are equal
JIF = 132.7 so GFD = 132.7
In the diagram shown, we are given that JIF and GFD are parallel lines. However, these lines are also same side interior angles. This means that they will be equal to each other since they are parallel lines. Remember, parallel lines are coplanar lines that do not intersect.
So if JIF = 132.7°, then GFD also measures 132.7°.

Answer:
(i) (4, 0)
(ii) -2
Step-by-step explanation:
y = 4 + 3x - x^2
(i)
At point A, y = 0
4 + 3x - x^2 = 0
x^2 - 3x - 4 = 0
(x - 4)(x + 1) = 0
x - 4 = 0 or x + 1 = 0
x = 4 or x = -1
The x-coordinate of point A is positive, so it is 4.
The coordinates of point A are (4, 0).
(ii)
y = mx + 8
We know point (4, 0) is on the line, so we substitute 4 for x and 0 for y and solve for m in the slope equation.
0 = m(4) + 8
4m = -8
m = -2

Answer:
y = 2.09x2 + 0.33x + 3.06
Step-by-step explanation:
just did the T3ST :)
The equation that represents the quadratic regression is y = 3.06 + 0.33x + 2.09x².
To find the quadratic regression equation that fits these data:
First, we determined the following values,
mean of x = 0
mean of y = 17
the correlation coefficient r = 0.9960376489
The precise metric used in a correlation analysis to quantify the strength of the linear relationship between two variables is the correlation coefficient. In a correlation report, r stands for the coefficient.
A = 3.060606061
B = 0.3333333333
C = 2.090909091
And the quadratic regression can be modeled by the Quadratic regression: y=A+Bx+Cx².
Therefore, the equation is y = 3.06 + 0.33x + 2.09x².

Find the 90th term of the arithmetic sequence 16 , 21 , 26
Answer:
The 90th term of the arithmetic sequence is 461.
Step-by-step explanation:
Arithmetic sequences concepts:
The general rule of an arithmetic sequence is the following:
[tex]a_{n+1} = a_{n} + d[/tex]
In which d is the common diference between each term.
We can expand the general equation to find the nth term from the first, by the following equation:
[tex]a_{n} = a_{1} + (n-1)*d[/tex]
In this question:
[tex]a_{1} = 16, d = 21 - 16 = 26 - 21 = 5[/tex]
So
90th term
[tex]a_{90} = a_{1} + (90-1)*d[/tex]
[tex]a_{90} = 16 + 89*5[/tex]
[tex]a_{90} = 461[/tex]
The 90th term of the arithmetic sequence is 461.
The Math Club wants to order t-shirts to recognize students who improved their performance in Algebra I for their hard work and effort. Hot Shirts charges $10 per shirt with a $15 set up charge. T-Shirt World charges $5 per shirt with a $50 set up charge.
Answer:
Cost of ordering t-shirts the same at both sides is 7
The cost is $85
Step-by-step explanation:
let x equal the number of tshirts
Hence:
15 + 10x = 50 + 5x
10x-5x= 50-15
5x = 35
35/5x
x = 7
Therefore the cost of ordering t-shirts the same at both sides is 7
The cost is $85
If a population of a certain type of animal has a mean of 44cm and a standard deviation of 3 cm what is the z-score for a member of the population witha height of 38cm
Answer:
The z-score is -2
Step-by-step explanation:
Here, we are asked to calculate the z-score of the height.
Mathematically, we can calculate z-score by using the formula below;
z-score = (x-mean)/SD
According to this question, mean = 44cm and SD = 3cm with x here = 38cm
Plugging these values into the z-score equation, we have
z-score = (38-44)/3 = -6/3 = -2

2. There were 1500 people at a high school football game. Student
tickets were $2.00 and adult tickets were $3.50. The total receipts for the
game were $3825. How many students bought tickets?
Let a = the number of adult tickets purchased.
Let s = the number of student tickets purchased.
a. Write a system of equations tha) can be used to determine the
number of adult and student tickets purchased.
b. Determine the number of adults tickets sold and the number of
student tickets sold. Use mathematics to explain how you
determined your answer.
Answer:
a = 950
s = 550
Step-by-step explanation:
Let a = the number of adult tickets purchased.
Let s = the number of student tickets purchased.
Therefore,
[tex]a + s = 1500 \implies \: s = 1500 - a...(1) \\ 2a + 3.5s = 3825...(2) \\ plugging \: s = 1500 - a \: in \: equation \: (2) \\ 2a + 3.5(1500 - a) = 3825 \\ 2a + 5250 - 3.5a = 3825 \\ 5250 - 1.5a = 3825 \\ 5250 - 3825 = 1.5a \\ 1425 = 1.5a \\ a = \frac{1425}{1.5} \\ \huge \red{ \boxed{ a = 950}} \\\implies s = 1500 - 950 \\ \huge \purple{ \boxed{s = 550}}[/tex]

The publisher agrees to pay the author 10% of the selling price of the first 6000 copies sold, and 12% of the selling price for all copies sold in excess of 6000. Altogether 25,300 copies of the book are sold. Calculate, correct to the pesewa: I) the total amount received by the author
Answer:
The total amount received by the author is of 221,616Gp.
Step-by-step explanation:
25,300 copies sold.
For the first 6000, he receives 10% of the selling price of 76 Gp.
For those in excess of 6000, that is, the next 25300 - 6000 = 19300, he receives 12% of the selling price of 76 Gp.
Total amount received by the author:
6000*0.1*76 + 19300*0.12*76 = 221,616
The total amount received by the author is of 221,616Gp.
