the 1560 members of the temecula community church have a method of quickly notifying members. the pastor and his secretary each call 3 members each of whom then call 3 other members, each of whom then calls 3 more members, and so on. how many rounds of calls are needed before all 1560 members are called
Answers
Using an exponential function, it is found that 7 rounds are needed before all 1560 members are called.
What is an exponential function?An exponential function is modeled as follows:
[tex]y = ab^x[/tex]
In which:
a is the initial value.b is the rate of change.Considering that initially one person knows the method, and then each person will call 3 other people, the parameters are given as follows:
a = 1, b = 3.
Hence the number of people that are called after x rounds is given by:
[tex]y = 3^x[/tex]
The number of rounds that will take for the 1560 members to be called is found as follows:
[tex]3^x = 1560[/tex]
[tex]\log{3^x} = \log{1560}[/tex]
[tex]x\log{3} = \log{1560}[/tex]
[tex]x = \frac{\log{1560}}{\log{3}}[/tex]
x = 6.69.
Rounding up, as at the end of the 6th call not all members will have been called, 7 rounds are needed before all 1560 members are called.

The value of the angle DCH is 72 degrees
How to determine the value of the angle DCH?The given parameters are
m = 11x+1,
DCH = 8x,
DCB = 172°.
The above means that:
11x + 1 + 8x = DCB
This gives
11x + 1 + 8x = 172
Evaluate the like terms
19x = 171
Divide both sides by 19
x = 9
Substitute x = 9 in DCH = 8x,
DCH = 8 * 9

a robot encounters a bunch of coins spread out on the ground. it examines each coin and, if the coin is heads, turns it to tails with 100% probability. if the coin is tails, it turns it to heads with 50% probability. he examines each coin once per cycle. if you have the robot cycle through the coins a very large number of times, what will eventually happen to the proportion of heads and the proportion of tails?
Answers
The proportion of heads and the proportion of tails p(H) + p(T) = 1.
Let p(H) represent the long-term probability that the coin will land on heads, and p(T) represent the long-term probability that the coin will land on tails.
Keep in mind that we must be at a tail and transition with a probability of 0.5 in order to get a head. So, p(H) = 0.5p(T).
Noting that we can either be at a head and transition to a tail with a probability of 1, or at a tail and transition to a tail with a probability of 0.5, we can obtain a tail. p(T) therefore equals 0.5 * p(T) + p(H).
Note that p(T) = 2 p is the result of the first two equations (H). We obtain p(H) = 1/3 and p(T) = 2/3 by substituting into p(H) + p(T) = 1. So, eventually, we'll have two-thirds of the coins with heads and one-third with tails.
What is the probability of finding three heads if there are five coins?The probability of finding three heads is 1/4. We should find the probability of finding three heads in five tosses with the help of the following formula:
p(x) = (x+1) C x-1 p(3 Heads)
p(x) = (5+1) C 4 -1p(3 Heads) = 7/8.

(PLS HELP I NEED THIS ITS DUE IN 30 MIN) The perimeter of the quadrilateral is 120 feet and BA = x + 30, BC = 2x + 10, and CD = x + 20. Determine the length of the sum of the smallest side and the largest side.
Answers
The length of the sum of the smallest value and the largest value is 105 feet.
Given data
BA = x + 30
BC = 2x + 10
CD = x + 20
Perimeter = 120 feet
How to find the length of the sum of the smallest side and the largest side.The perimeter refers to the sum of all the dimensions which is given as 120 feet. We sum the dimensions given to find the value of x.
This is done as follows:
Perimeter = BA + BC +CD
120 = x + 30 + 2x + 10 + x + 20
120 = x + 2x + x + 30 + 10 + 20
120 = 4x + 60
4x = 120 - 60
4x = 60
x = 60 / 4
x = 15
plugging in x = 15 into the dimensions given we have
BA = x + 30
BA = 15 + 30
BA = 45
BC = 2x + 10
BC = 2 * 15 + 10
BC = 30 + 40
BC = 70
CD = x + 20
CD = 15 + 20
CD = 35
Hence we can say that the smallest value is 35 and the largest value is 70.
sum of the values
70 + 35 = 105
The sum of the smallest value and the largest value is 105 feet.

If m< EBC = 3y+10 and m< ABE = 2y-20, find m< EBF.
Answers
By applying the supplementary angle theorem, the magnitude of angle EBF (m<EBF) is equal to 60°.
What is a supplementary angle?A supplementary angle can be defined as two (2) angles or arc whose sum is equal to 180 degrees.
Mathematically, a supplementary angle can be calculated by using this formula:
Q + R = 180
Where:
Q and R are measure of the angles subtended.
Substituting the given parameters into the formula, we have;
m<EBC + m<ABE = 180
3y + 10 + 2y - 20 = 180
5y - 20 = 180
5y = 180 + 20
5y = 200
y = 200/5
y = 40
Now, we can determine the magnitude of angle EBF (m<EBF) based on the given diagram:
m<ABE = m<EBF
m<EBF = 2y - 20
m<EBF = 2(40) - 20
m<EBF = 80 - 20

please help it’s about finding the mean
Answers
The mean of the data is 16 cm and the absolute mean deviation is 1.4 cm.
Given we have the data set values.
Total number of data set values = 10
to find the mean we need to find the sum of the data set values and then divide it by the total number of data set values.
Therefore, mean = 13₊14₊14₊16₊16₊16₊16₊18₊18₊19 / 10
mean = 160/10
mean = 16 cm
To find the absolute mean deviation we need to find the deviation from the mean, from that the absolute mean deviation.
Data value Deviation from mean Absolute mean deviation
13 13 ₋ 16 = ₋3 I ₋3 I = 3
14 14 ₋ 16 = ₋2 I ₋2 I = 2
14 14 ₋ 16 = ₋2 I ₋2 I = 2
16 16 ₋ 16 = 0 0
16 16 ₋ 16 = 0 0
16 16 ₋ 16 = 0 0
16 16 ₋ 16 = 0 0
18 18 ₋ 16 = 2 2
18 18 ₋ 16 = 2 2
19 19 ₋ 16 = 2 3
Now the total of the absolute mean deviation is 14
divide it by 10
= 14/10
= 1.4 cm
Hence we get the mean and the absolute mean deviation as 16 cm and 1.4 cm.

please help me with this question
Answers
The equation of the parabola in vertex form is y=-2(x-4)²+4.
Given that the vertex point is (4,4), (3,2).
The equation of a parabola in vertex form is y=a(x-h)²+k where a is called stretch coefficient and the point (h,k) is the vertex of the parabola.
A parabola with its vertex at the point (4,4), therefore h=4,k=4 and we can write
y=a(x-4)²+4
To find the value of a we use the point (3,2). Substituting on the equation we get:
y=a(x-4)²+4
2=a(3-2)²+4
2=a(1)²+4
2=a+4
2-4=a
-2=a

The value of 8-√5 is approximately 5.76 which is calculated by rounding the square root of 5 to 2 decimal places.
A number y whose square (the outcome of multiplying the number by itself, or y × y), is x (y² = x) is said to be the square root of a number x.
For instance, since 4² = (4)² = 16, 4 and -4 are the square roots of 16.Every nonnegative real number x has a singular nonnegative square root, denoted by √n where the symbol √ is known as the radical sign or radix, which is known as the primary square root.For instance, we write to indicate that the primary square root of √9 is 3. The radicand is the phrase (or integer) whose square root is being analyzed. The quantity or phrase that appears beneath the radical sign is known as the radicand.Now the given expression is of the form ( 8 - √5 )
We know that √5 = 2.2360... ≈ 2.24 (rounded to 2 decimal places.)
∴ 8 - √5
= 8 - 2.24
