Triangle ABC is an equilateral triangle and O is the center of its inscribed circle. If the area of the circle is 4π cm2, what is the area of triangle ABC?
Answer:
does one side of equilateral triangle is diameter. I will redo it.
Answer:
Area of ABC = 16[tex]\sqrt{2}[/tex]
Step-by-step explanation:
if Area of Circle is π·r², which in this case equals 4π, then the radius is 2; this gives us the height of the triangle as 4
since it's a 60-60-60 triangle, the height perpendicular to base creates a 30-60-90 triangle, whose sides are in the ratio of 1 : √2 : 2
therefore the entire base is 4√2 + 4√2 or 8√2
A (ΔABC) = 1/2(4) · 8√2 = 16√2

A poll conducted a week before the school election to the student council showed that Janice would win with 63% of the vote. The margin of error was 14%. If Janice needs to receive at least half the votes to win the election, can we be confident of Janice's victory?
OPTIONS:
No, because she could receive as low as 14% of the vote.
No, because she could receive as low as 49% of the vote.
Yes, because she could receive as much as 77% of the vote.
Yes, because the poll stated that she will win with 63% of the vote.
Answer:
No, because she could receive as low as 49% of the vote.
Step-by-step explanation:
Given that:
Poll suggestion = 63%
Margin of Error (E) = 14%
This means that; the range or interval in which the vote obtained could fall would be ;
Poll suggestion ± margin of Error
63% ± 14%
Lower bound attainable = (63% - 14%) = 49%
Upper bound attainable = (63% + 14%) = 77%
Since, winning actually requires obtaining atleast half of the votes (that is 50%) ; and suggested poll suggested votes could fall as low as 49% ; then Janice can't be so confident of victory.

Suppose that the value of a stock varies each day from $10.82 to $25.17 with a uniform distribution. Find the third quartile, i.e., 75% of all days the stock is below what value
Answer: Third quartile =$21.58
Step-by-step explanation:
Let x be value of a stock .
For uniform distribution,
probability density function = [tex]\dfrac{1}{b-a}=\dfrac{1}{25.17-10.82}=\dfrac1{14.35}=\dfrac{100}{1435}[/tex]
Let a be the stock value such that P(x<a) =75% or 0.75
[tex]\Rightarrow\ \int ^{a}_{10.82}f(x)\ dx=0.75\\\\\Rightarrow\ \int ^{a}_{10.82}\dfrac{100}{1435}\ dx=0.75\\\\\Rightarrow\dfrac{100}{1435}[x]^{a}_{10.82}=0.75\\\\\Rightarrow \dfrac{100}{1435}(a-10.82)=0.75\\\\\Rightarrow a-10.82=0.75\times\dfrac{1435}{100}\\\\\Rightarrow a-10.82=10.7625\\\\\Rightarrow a= 10.7625+10.82= $$21.5825\approx $$21.58[/tex]
Hence, 75% of all days the stock is below $21.58 or Third quartile =$21.58 .

solve 1/2x + 6y = 12 y = x + 15
The value of x is -12.07, and y is 3.07 for equation 1/2x + 6y = 12, y = x + 15.
We have to solve the given equations, 1/2x + 6y = 12 y = x + 15.
Equation; 1/2x + 6y = 12 and y = x + 15.
The given equations are solved by using the elimination method following all the steps given below.
The equations are,
[tex]\dfrac{1}{2}x + 6y = 12\\\\y = x+15[/tex]
Substitute the value of y in equation 1 from equation 2,
[tex]\dfrac{1}{2}x + 6(x+15) = 12\\\\\dfrac{1}{2}x + 6x + 90 = 12\\\\\dfrac{x+12x+180}{2} = 12\\\\13x + 181 = 12 \times 2\\\\13x + 181 = 24\\\\12x = 24-181\\\\12x = -157\\\\x = \dfrac{-157}{13}\\\\x = -12.07[/tex]
Substitute the value of x in equation 2,
[tex]y =- 12.07+15\\\\y = 3.07[/tex]
Hence, The required value of x is -12.07, and y is 3.07 for equation 1/2x + 6y = 12, y = x + 15.

The geometrical series is a series of numbers. The nth term of the series is [8× 0.5⁽ⁿ⁻¹⁾].
What is geometrical series?The geometrical series is a series of numbers where the ratio of any two consecutive numbers is constant.
In a geometric series, r is the ratio between any two consecutive terms, therefore, the ratio of these terms can be written as,
r = (4/8) = (1/2)
Also, a₁ is the first term of the series, therefore, the first term of the series will be 8.
Thus, the nth term of this series will be equal to,
[tex]n^{th} = a_1 \times r^{(n-1)}\\\\n^{th} = 8 \times (\dfrac{1}{2})^{(n-1)}[/tex]
Hence, the nth term of the series is [8× 0.5⁽ⁿ⁻¹⁾].
