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.)

Answer:
a. 0.41
b. 0.22
Step-by-step explanation:
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 ...
[tex]\begin{array}{c|ccccc}n&1&2&3&4&5\\p(n)&0.11&0.23&0.18&0.26&0.22\end{array}[/tex]
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

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.

The manager of a juice bar polled 56 random customers to get feedback on a new smoothie. the results are shown in the frequency table. a 4-column table with 3 rows. the first column has no label with entries adult, child, total. the second column is labeled like with entries 23, 18, 41. the third column is labeled dislike with entries 6, 9, 15. the fourth column is labeled total with entries 29, 27, 56. complete the statements using the table. the number of children who disliked the smoothie is . the total number of children is . the conditional relative frequency that a customer disliked the new smoothie, given that the person is a child is approximately .
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%
Thus, the number of children who disliked the smoothie is 9, total children is 27, and conditional relative frequency is 33%

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)

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

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]

The sum of the 2 numbers is 83. The difference of the 2 numbers is 13. What is the product of the 2 numbers?
Answer:
1680
Step-by-step explanation:
To find the product of the two numbers, you can work out the values of the numbers, or you can work directly with the sum and difference figures.
__
Deriving the formulaWe note that the square of a sum is ...
(a +b)² = a² +2ab +b²
and the square of a difference is ...
(a -b)² = a² -2ab +b²
The difference of these squares is ...
(a +b)² -(a -b)² = (a² +2ab +b²) -(a² -2ab +b²) = 4ab
__
Using the formulaThat is, dividing the difference of the squares of the sum and difference by 4 will give the desired product:
P = (83² -13²)/4 = (6889 -169)/4 = 6720/4 = 1680
The product of the two numbers is 1680.
_____
Additional comment
If we factor the formula we derived, we find ...
P = ((a +b)² -(a -b)²)/4 = ((a +b) +(a -b))/2 × ((a +b) -(a -b))/2
This simplifies to ...
(2a)/2 × (2b)/2 = a × b
In short:
a = ((a +b) +(a -b))/2, the average of the sum and differenceb = ((a +b) -(a -b))/2, half the difference of the sum and differenceUsing this fact, we find a=(83+13)/2 = 48; b=(83-13)/2 = 35, and the product is (48)(35) = 1680, as above.
