Given: AC = AB, CD = DE
m∠ABC = 70°, m∠ ECB = 35°
Prove: DE ║BC
m∠ACB = m∠______, By reason ( Base angles theorem, Exterior Angle theorem, Supplementary angles, Vertical Angles theorem ) - choose one
Answer:
a)[tex]\angle ACB = \angle ABC[/tex] By Base angle theorem
b)DE||BC since[tex]\angle DEC=\angle ECB[/tex] and they are alternate interior angles
Step-by-step explanation:
Given: AC = AB, CD = DE
∠ABC = 70°, m∠ ECB = 35°
Refer the attached figure
AB = AC
So, By Base angle theorem : if the sides of a triangle are congruent then the angles opposite these sides are congruent.
So, [tex]\angle ACB = \angle ABC[/tex]
So,[tex]\angle ACB = \angle ABC =70^{\circ[/tex] ----1
CD = DE
So, by Base theorem
[tex]\angle DCE = \angle DEC[/tex]
Let [tex]\angle DCE[/tex] be x
So,[tex]\angle DCE = \angle DEC[/tex]
[tex]\angle ACB= \angle DCE+\angle ECB = x+35[/tex]
Using 1
70 = x+35
35=x
[tex]\angle DCE = \angle DEC =35^{\circ}[/tex]
Now[tex]\angle DEC=\angle ECB=35^{\circ}[/tex]
So, DE||BC since[tex]\angle DEC=\angle ECB[/tex] and they are alternate interior angles
Many states run lotteries to raise money. A website advertises that it knows "how to increase YOUR chances of Winning the Lottery." They offer several systems and criticize others as foolish. One system is called Lucky Numbers. People who play the Lucky Numbers system just pick a "lucky" number to play, but maybe some numbers are luckier than others. Let's use a simulation to see how well this system works. To make the situation manageable, simulate a simple lottery in which a single digit from 00 to 99 is selected as the winning number. Any value can be picked, but for this exercise, pick 1 as the lucky number. What proportion of the time do you win

Many states run lotteries to raise money. A website advertises that it knows "how to increase YOUR chances of Winning the Lottery." They offer several systems and criticize others as foolish. One system is called Lucky Numbers. People who play the Lucky Numbers system just pick a "lucky" number to play, but maybe some numbers are luckier than others. Let's use a simulation to see how well this system works. To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number. Any value can be picked, but for this exercise, pick 1 as the lucky number. What proportion of the time do you win?
Answer:
10%
Step-by-step explanation:
We are told that To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number.
This means the total number of single digits that could possibly be a winning one is 10.
Since we are told that only 1 can be picked, thus;
Probability of winning is; 1/10 = 0.1 or 10%
In Mr. Britt's class the distribution of ages of his students has a mean of 115 months and a standard
deviation of 3.6 months.
If no students leave or join the class, what will be the mean and standard deviation of the distribution of
student's ages 4 months later?
Using statistical concepts, it is found that the mean will be of 119 months, while the standard deviation will be of 3.6 months, given by option C.
-------------------------------------
The mean of a data-set is the sum of all values divided by the number of values.The standard deviation is the square root of the sum of the difference squared of each observation and the mean, divided by the number of values.If x is added to all values of a data-set, it is also added to the mean, while the standard deviation remains constant.-------------------------------------
Mean of 115 months and standard deviation of 3.6 months.4 months later is the same as adding 4 to each observation.Thus, the mean will be of 115 + 4 = 119 months, while the standard deviation remains constant at 3.6 months.A similar problem is given at https://brainly.com/question/20640860

if the slope of BC is 1/2 what is the slope of AC
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete.
However, I'll answer base on the following assumptions.
1. AC and BC are parallel.
2. AC and BC are perpendicular
For (1)
Parallel lines have equal slopes.
So, AC = BC = ½
For (2)
Slope of perpendicular line is:
m1 * m2 = -1
Take m1 as slope of BC
So, we have
½ * m2 = -1
Solve for m2
m2 = -1/½
m2 = -1 * 2
m2 = -2
Hence, the slope of AC is -2

Which represents the symbolic notation of the compound statement below?
“Memorial Day is in July or parallel lines intersect.”
Answer:
Option (A)
Step-by-step explanation:
Statement 'p':
"Memorial Day is in July"
Statement 'q':
"Parallel lines intersect"
Since both the statement are joined by the 'OR',
Statements p and q will be joined by disjunction represented by the sign (∧).
Therefore, two statements will be represented as,
p ∧ q
Option (A) will be the correct option.
Jesse's mother gave him 55 pieces of candy to give to his friends at his birthday party. He gave 4 pieces to each of his friends and still had 3 pieces left. The equation 4x + 3 = 55 can be used to find the number of friends (x) at the party.
How many friends were at Jesse's party?
A) 13
B) 14
C) 15
D) 16
The number of friends at Jesse's party is 14. The correct answer is B).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
To determine the number of friends (x) at the party, we can use the equation 4x + 3 = 55.
This equation represents the total number of pieces of candy (4x) that Jesse gave to his friends, plus the number of pieces he had left over (3), which equals the total number of pieces of candy he had to start with (55).
To solve for x, we can start by subtracting 3 from both sides of the equation:
4x + 3 = 55
4x = 52
Next, we divide both sides of the equation by 4 to get x alone:
x = 52 / 4
x = 13
However, it's impossible to have a fraction of friends, so the number of friends at Jesse's party is 14.

you plug the number for the variable into the equation (3(2)²+6order of operations say exponents first so you do 2²=4 so you have 3(4)+6then you multiple 3•4=12 so 12+6finally you add 12+6=1823
plug in the number for the variable so 5–(-5)so a negative and a minus will make it addition (negative + negative = positive)do it is 5+5 which equals 10f(x) = square root x-3

In a sequence of numbers, a3=0, a4=4, a5=8, a6=12, and a7=16. Based on this information, which equation can be used to find the nth term in the sequence, an?
Answer: aₙ = -12 + 4*n
Step-by-step explanation:
We know that:
a₃ = 0
a₄ = 4
a₅ = 8
a₆ = 12
a₇ = 16
This seems to be an arithmetic sequence.
To test this, we need to calculate the difference between any two consecutive terms in the sequence, and this must be a constant for any pair that we choose.
a₄ - a₃ = 4 - 0 = 4
a₅ - a₄ = 8 - 4 = 4
a₆ - a₅ = 12 - 8 = 4
etc
we can conclude that this is an arithmetic sequence.
The n-th term in an arithmetic sequence, where the increase between consecutive terms is 4, is:
aₙ = aₙ₋₁ + 4.
Another way is:
aₙ = a₀ + n*4.
Where to find a₀, we can start with the value that we know and go back:
a₂ = a₃ - 4 = -4
a₁ = a₂ - 4 = -8
a₀ = a₁ - 4 = -12
Then the n-th term can be written as:
aₙ = -12 + 4*n

Answer: it amazing
Step-by-step explanation:
a petting zoo has 5 lambs 11 rabbits 4 goats and 4 piglets. find the ratio of goats to the total number of animals. write the ratio in the simplest form then explain its meaning
Answer:
1:6 or 1/6
Step-by-step explanation:
Because the question asks for the goats to the total number of animals, you have to write the ratio in the same order. So, there are 4 goats, and to find the total number of animals, you just add every number.
5+11+4+4=24
The result would be 4:24, and because you need the ratio in the simplest form, you just divide both sides by the same greatest number. Both 4 and 24 can be divided evenly by 4. So, when you simplify, the answer comes out as 1:6. (Ratios can also be written as fractions, just so you know!! For example, the ratio 1:6 can be written as 1/6; both answers would be correct.)
Hope this helps!!!! Have an amazing day :3
As an accountant, you have calculated income taxes for a customer for the last 3 years. During those three years, the customer made a tax payment of $1,250, received a tax refund of $550, and made a tax payment of $925. The customer also paid a processing fee of $60 each year.
Answer:
The total amount customer paid during those 3 years is $1685
Step-by-step explanation:
We are supposed to find the total amount customer paid during those 3 years
Customer made a tax payment = $1250
He received a refund of amount = 550
So, amount paid by him = 1250-550
Amount paid by him ==700
Now again He made a tax payment = $925
Processing fee = $60
So, Total Amount paid by him =700+925+60
Total Amount paid by him =1685
Hence the total amount customer paid during those 3 years is $1685
