On average, every minute of every day, 167 babies are born. The bar graph represents the results
of a single day of births, deaths, and population increase worldwide.
Each day, the number of births in the world is 45 thousand less than three times the number of
deaths.
a.) If the population increase in a single day is 241 thousand, determine the number of births and deaths per day.
There are____ thousand births per day
There are ____ thousand deaths per day
Answer:
Let x thousand births per day
Let y thousand deaths per day
Each day, the number of births in the world is 45 thousand less than three times the number of
deaths.
x=3y-45 (1)
Population increase= birth - death
=x-y(2)
substitute (1) into (2)
3y-45-y=241
2y-45=241
2y=196 (plus 45 from both side)
y=98 (divide 2 from both side)
x-y=241
x-98=241
x=339 ( pluse 98 from both side)
So, There are 339 thousand births per day
There are 98 thousand deaths per day

Answer:
TU = 15
Step-by-step explanation:
The two rectangles are similar. That means that the lengths of corresponding sides are in the same ratio.
Pairs of corresponding sides:
MN, ST
NO, TU
OP, UV
PM, VS
Equal ratios of lengths of corresponding sides:
MN/ST = NO/TU = OP/UV = PM/VS
Plug in the given information:
MN/ST = 10/x = 4/6 = PM/VS
10/x = 4/6
4x = 10 × 6
4x = 60
x = 15
TU = 15
name the polynomial based on its degree and number of terms. 2 - 11x^2 - 8x + 6x^2
Step-by-step explanation:
This polynomial has like terms that can further be simplified
2 - 11x^2 + 6x^2- 8x
2 - 5x^2 - 8x
multiply by negative to take 2 to the right.
-(2 - 5x^2 - 8x)
= 5x^2 + 8x - 2
It's named a Second Degree Polynomial because the highest degree(exponent) of x in the final solution is 2.
it has 3 terms : 5x^2 , 8x , 2

Using the vertex of a quadratic function, it is found that Phoenix received the highest amount of precipitation on the month of May.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex]
[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, the precipitation each month x in Phoenix is given by:
[tex]y = -0.04088x^2 + 0.4485x + 1.862[/tex]
Hence the coefficients are a = -0.04088, b = 0.4485, c = 1.862, and the month for which the precipitation will be highest is given by:
[tex]x_v = -\frac{0.4485}{2(-0.04088)} = 5.48[/tex]
Hence during the month of May.

Cisca, 12 years old, is three times as old as Catherine. How old will she be when she's twice as old as Catherine?
Step-by-step explanation:
Divide 12 by 3 to determine Catherine's age.
[tex]12 \div 3 = 4[/tex]
Catherine is 4 years old when Cisca is 12 years old.
Let's identify when Cisca will be twice as old as Catherine by representing the ages per future years.
Year 1: 13, 5
Year 2: 14, 6
Year 3: 15, 7
Year 4: 16, 8
Year 5: 17, 9
Year 6: 18, 10
In 4 years, Cisca will be twice as old as Catherine.
Her age is 16.
She would be 4 years
Calculation of ageAge of Catherine = X
Age of Cisca = 12yrs = 3x
Therefore X = 12/3= 4 years.
Actual age of Catherine = 4 years.
Twice ( 2x) age of Catherine = 2×4= 8
Therefore, she will be 4 years to be twice as old as Catherine

Use the quadratic formula to solve
x^2-4x+3
Show your work. Then describe the solution. if you dont describe the solution it will get reported.
Answer:
x = 3, x = 1
The points at which the curve crosses the x-axis are (3, 0) and (1, 0)
Step-by-step explanation:
Quadratic formula:
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]
Quadratic equation: [tex]ax^2+bx+c[/tex]
Therefore, for [tex]x^2-4x+3[/tex]:
a = 1 b = -4 c = 3
Inputting values into quadratic formula:
[tex]x=\dfrac{4\pm\sqrt{(-4)^2-(4\times1\times3)} }{2\times1}[/tex]
[tex]\implies x=\dfrac{4\pm\sqrt{16-12} }{2}[/tex]
[tex]\implies x=\dfrac{4\pm\sqrt{4} }{2}[/tex]
[tex]\implies x=\dfrac{4\pm2 }{2}[/tex]
[tex]\implies x=2\pm1[/tex]
[tex]\implies x=3, x=1[/tex]
Therefore, the points at which the curve crosses the x-axis are (3, 0) and (1, 0)
[tex]\\ \tt\hookrightarrow x^2-4x+3=0[/tex]
a=1b=-4c=3[tex]\\ \tt\hookrightarrow x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

On solving the provided question, we can say that Cai's thinking expression will be area of the poster k = Ax Bt +Cz => K = x² + lb + 1/2wm
What is Expression?An expression is combination of variables, numbers and operators.
Cai's thinking expression will be.
The three sections are of different shapes which includes a square, rectangle and a triangle.
The area of square is side times of side= x²
The area of rectangle is length times of breadth (lb)
The area of triangle=1/2length times of breadth(1/2lb)
Area of the poster k = Ax+By+Cz
Ax = x²

Note in step 2, I factored each number in the square root to pull out the largest perfect square factor. From there, I used the rule that [tex]\sqrt{A*B} = \sqrt{A}*\sqrt{B}[/tex] to break up the roots.
Answer:
4
Step-by-step explanation:
We first simplify $\sqrt{72}$ and $\sqrt{8}$:\begin{align*}
\sqrt{72} &=\sqrt{36\cdot 2} = \sqrt{36}\cdot \sqrt{2} = 6\sqrt{2},\\
\sqrt{8} &= \sqrt{4\cdot 2} = \sqrt{4}\cdot \sqrt{2} = 2\sqrt{2}.
\end{align*}Then, we have
\[\dfrac{2\sqrt{72}}{\sqrt{8}+\sqrt{2}} = \dfrac{2\left(6\sqrt{2}\right)}{2\sqrt{2} + \sqrt{2}}
= \dfrac{12\sqrt{2}}{3\sqrt{2}} = \dfrac{12}{3}\cdot \dfrac{\sqrt{2}}{\sqrt{2}} = \boxed{4}.\]

If P(E) = 0.32, then what are the odds against E?
Answer:
0.68 : 0.32
Step-by-step explanation:
the probability of all the outcomes of an event is always 1 .
if P(E) = 0.32,
P(E') = 1 - 0.32
= 0.68
N.B that P(E') is the same as P( not E ).
since your answer should be given in the ratio form, as the odds against E ( probability not E : probability E),
P(E') : P(E)
0.68 : 0.32

Let us check if this is the answer:
the first numbers in the table are 0 and 14
0 plus 14 equals 14.
Now the next two numbers on the table:
