Which is NOT true of the construction of an angle bisector?
A)You start with any angle
B) When you're finished, you have a line that bisects your segment
C) You must draw an arc using the vertex as the center
D) When you're finished, you have a ray that bisects your angle
Answer:
B) When you're finished, you have a line that bisects your segment
Step-by-step explanation:
An angle bisector is a ray that divides a given angle into two congruent parts. There is no line segment involved.
__
The statement that is not true about this construction is ...
B) When you're finished, you have a line that bisects your segment
_____
Additional comment
The construction effectively creates an arc of a circle, then creates the perpendicular bisector of the chord of that arc. The center of the circular arc is the vertex of the angle being bisected. The constructed perpendicular bisector of the chord also bisects the angle. (The chord is never actually drawn, and the "circular arc" may be two short arcs across the rays of the angle being bisected.)

Find the 9th term.
Step-by-step explanation:
seems to be multiplication, because the differences between the numbers change.
so, let's find the factor.
2 × f = 5
f = 5/2
5 × f = 5 × 5/2 = 25/2
ok, the factor 5/2 is confirmed.
a1 = 2
a2 = a1 × 5/2 = 2 × 5/2 = 10/2 = 5
a3 = a2 × 5/2 = a1 × 5/2 × 5/2 = 2 × 5/2 × 5/2 = 25/2
an = an-1 × 5/2 = a1 × (5/2)^(n-1) = 2 × (5/2)^(n-1)
a9 = 2 × (5/2)⁸ = 2 × 390,625/256 =
= 390,625/128 = 3,051.7578125
The geometric sequence's 9th term will be 3,051.7578.
What is a geometric sequence?A geometric sequence is one in which each term is obtained by multiplying the previous term by the same number throughout the series.
Let a₁ represent the first term and r represent the common ratio. The geometric sequence's nth term is then given as,
aₙ = a₁ x (r)ⁿ⁻¹
The sequence is given below.
2, 5, [tex]\dfrac{25}{2}[/tex],
The first term is 2. And the common difference is given as,
[tex]r = \dfrac{5}{2}[/tex]
r = 2.5
Then the 9th term is given as,
a₉ = 2 x (2.5)⁹⁻¹
a₉ = 2 x (2.5)⁸
a₉ = 2 x 1525.8789
a₉ = 3,051.7578
The 9th term of the geometric sequence will be 3,051.7578.

factorise fully 50x + 100
The required factorized form of the given expression is 50(x+2), where 50 is the greatest common factor (GCF).
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).
We have been given that the expression below as
50x + 100
We have to determine the factor of the expression 50x + 100
First, we have to find the Greatest Common Factor (GCF).
GCF = 50
2 Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
50(50x/50 + 100/50)
Simplify each term in parentheses.
50(x+2)
Therefore, the required factorized form of the given expression is 50(x+2).

A movie premiere had a full house of 350 film buffs. The price of the tickets was $6 for adults and $4 for underage. The income from ticket sales was $1,600. What is the number of adult's, x, who attended?
A 80
B 140
C 100
D 250
Answer:
C
Step-by-step explanation:
let x be number of adults and y the number of underage , then
x + y = 350 → (1)
6x + 4y = 1600 → (2)
multiplying (1) by - 4 and adding to (2) will eliminate y
- 4x - 4y = - 1400 → (3)
add (2) and (3) term by term to eliminate y
(6x - 4x) + (4y - 4y) = 1600 - 1400
2x + 0 = 200
2x = 200 ( divide both sides by 2 )
x = 100
the number of adults who attended is 100

Triangle ABC has angles A; B; C is proportional to 1; 2; 3 then the measure of the angles of the triangle is
Step-by-step explanation:
Let the angle of triangle be x , so each angle will be 1x , 2x , 3x respectively.
We know that sum of all angles in triangle is 180°
So ,
1x + 2x + 3x = 180°
6x = 180°
x = 30°
Therefore , each angle would be 30° , 60° , 90° respectively.
What is the surface area of the top portion of the barn that will need repairs, including the roof? Explain how you determined your answer.
The surface area of the roof is the amount of space on it
The surface area of the roof is 600 square meters,
How to determine the surface area?From the complete question, we have the parameters for the roof:
The roof is a square based pyramidThe height (h) is 10 meters.The base (b) of the pyramid is 15 meters.The surface area of the roof is calculated using:
[tex]A = b^2 + 2b \sqrt{\frac{b^2}4 + h^2}[/tex]
So, we have:
[tex]A = 15^2 + 2 * 15 \sqrt{\frac{15^2}4 + 10^2}[/tex]
Evaluate the exponents
[tex]A = 225 + 30 * \sqrt{\frac{225}4 + 100[/tex]
The equation becomes
[tex]A = 225 + 30 * 12.5[/tex]
Evaluate the sum
[tex]A = 600[/tex]
Hence, the area of the roof is 600 square meters

Number of Blueback Herring
The dot plot with the least number of sites has the least frequency
The dot plot has the least number of sites is the Shield Darter
How to determine the dot plot?To determine the dot plot with the least number of sites, we simply calculate the total frequency of each dot plot
So, we have:
Shield Darter = 3 + 1 + 4 + 2 + 3 + 1 + 1
Shield Darter = 15
Calico Crayfish = 1 + 1 + 3 + 4 + 1 + 2 + 4 + 2
Calico Crayfish = 18
Zebra Mussel = 1 + 3 + 2 + 5 + 1 + 1 + 2 + 3 + 2
Zebra Mussel = 20
Blue back Herring = 3 + 3 + 2 + 1 + 3 + 1 + 4
Blue back Herring = 17
From the computation above, the least frequency is
Shield Darter = 15
Hence, the dot plot has the least number of sites is the Shield Darter

A lab is monitoring the population of mice in a sample. Scientists noticed the number of mice triples every week. If there were initially 4 mice in the sample, how many mice will there be after 6 weeks?
A. 324 Mice
B. 972 Mice
C. 2916 Mice
D. 8748 Mice
C. 2916 Mice
Step-by-step explanation:
4 x 3^6 = 2916
Because as the mice increases, you triple that amount, instead of tripling 4 & multiplying by 6.
So, you're doing this instead:
4 x 3 = 12 (1 wk)
12 x 3 = 36 (2 wk)
36 x 3 =108 (3 wk)
108 x 3 = 324 (4 wk)
324 x 3 = 972 (5 wk)
972 x 3 = 2916 (6 wk)

The number of children who disliked the smoothie is 9, total children is 27, and conditional relative frequency is 33%
What is a conditional relative frequency?It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell to total frequency.
From the data given in the table:
The number of children who disliked the smoothie = 9
The total number of children = 27
To find the conditional relative frequency that a customer disliked the new smoothie(if the person is a child)
It is the ratio of total number of children who disliked the smoothie to total number of children, mathematically:
= 9/27
= 0.3333
= 0.3333×100
= 33.33 ≈ 33%

The sum of probabilities over all outcomes is 1. This fact can be used to fill the table. The other questions can be answered by reference to the table.
__
1.The total of all probabilities is 1:
k +0.23 +0.18 +0.26 +2k = 1
3k = 0.33 . . . . . . . collect terms, subtract 0.67
k = 0.11 . . . . . . . divide by 3
2k = 0.22 . . . . find 2k
Then the table is ...

a.Landing on 2 or 3 are mutually exclusive outcomes, so the probability of one or the other is the sum of their individual probabilities:
p(2 or 3) = 0.23 +0.18
p(2 or 3) = 0.41
__
b.The table tells us ...
p(5) = 0.22
